Torsion vortex cavitation hydrodynamic heat generator. Heat generator cavitation for space heating

The purpose of the Potapov vortex heat generator (VTG), made by hand, is to get heat only with the help of an electric motor and a pump. Basically, this device is used as an economical heater.

Scheme of the device of the vortex heat system.

Since there are no studies to determine the parameters of the product depending on the power of the pump, approximate dimensions will be highlighted.

The easiest way is to make a vortex heat generator from standard parts. Any electric motor will work for this. The more powerful it is, the greater the volume of water will heat up to a given temperature.

The main thing is the engine

You need to choose a motor depending on what voltage is available. There are many schemes with which you can connect a 380 Volt motor to a 220 Volt network and vice versa. But that's another topic.

Start assembling the heat generator with an electric motor. It will need to be fixed on the bed. The design of this device is a metal frame, which is easiest to make from a square. Dimensions will need to be selected on site for those devices that will be available.

Drawing of a vortex heat generator.

List of tools and materials:

• angle grinder;
• welding machine;
• electric drill;
• set of drills;
• open-end or box wrenches for 12 and 13;
• bolts, nuts, washers;
• metal corner;
• primer, paint, paint brush.

1. Cut the squares with an angle grinder. Using a welding machine, assemble a rectangular structure. Alternatively, you can assemble with bolts and nuts. This will not affect the final version of the design. Choose the length and width so that all the details fit optimally.
2. Cut out another piece of square. Attach it as a cross member in such a way that you can secure the engine.
3. Paint the frame.
4. Drill holes in the frame for the bolts and install the motor.

Pump installation

Now it will be necessary to pick up a water pump. Now in specialized stores you can buy a unit of any modification and power. What should you pay attention to?

1. The pump must be centrifugal.
2. Your engine will be able to spin it.

Install the pump on the frame, if you need to make more crossbars, then make them either from a corner or from strip iron of the same thickness as the corner. The coupling is hardly possible to make without a lathe. So you have to order it somewhere.

Scheme of a hydrovortex heat generator.

Potapov's vortex heat generator consists of a body made in the form of a closed cylinder. At its ends there must be through holes and branch pipes for connection to the heating system. The secret of the design is inside the cylinder. A jet should be located behind the inlet. Its hole is selected individually for this device, but it is desirable that it be half the size of a quarter of the diameter of the pipe body. If you do less, then the pump will not be able to pass water through this hole and will start to heat up itself. In addition, internal parts will begin to break down intensively due to the phenomenon of cavitation.

Tools: angle grinder or hacksaw, welding machine, electric drill, adjustable wrench.

Materials: thick metal pipe, electrodes, drills, 2 threaded pipes, couplings.

1. Cut a piece of thick pipe with a diameter of 100 mm and a length of 500-600 mm. Make an external groove on it about 20-25 mm and half the thickness of the pipe. Cut the thread.
2. Make two rings 50 mm long from the same pipe diameter. Cut an internal thread on one side of each half ring.
3. From the same thickness of flat metal as the pipe, make covers and weld them on the side of the rings where there is no thread.
4. Make a central hole in the covers: one for the diameter of the jet, and the other for the diameter of the nozzle. On the inside of the cover, where the jet is located, make a chamfer with a larger diameter drill. The result should be a nozzle.
5. Connect the heat generator to the system. Attach the pipe where the nozzle is located to the pump in the hole from which water is supplied under pressure. Connect the inlet of the heating system to the second branch pipe. Connect the system outlet to the pump inlet.

The water under pressure, which the pump will create, will pass through the nozzle of the vortex heat generator, which you make yourself. In the chamber, it will begin to heat up due to intensive mixing. Then feed it into the heating system. To regulate the temperature, place a ball lock behind the nozzle. Cover it, and the vortex heat generator will drive water inside the housing longer, which means that the temperature in it will begin to rise. This is how the heater works.

Ways to improve performance

Heat pump diagram.

There is heat loss in the pump. So Potapov's vortex heat generator in this version has a significant drawback. Therefore, it is logical to surround the submerged pump with a water jacket so that its heat also goes to useful heating.

Make the outer case of the entire device slightly larger than the diameter of the available pump. This can be either a finished pipe, which is desirable, or a parallelepiped made of sheet material. Its dimensions must be such that the pump, the coupling and the generator itself enter inside. The wall thickness must withstand the pressure in the system.

In order to reduce heat loss, make thermal insulation around the body of the device. You can protect it with a casing made of tin. As an insulator, use any heat-insulating material that can withstand the boiling point of the liquid.

1. Assemble a compact device consisting of a submersible pump, a connecting pipe and a heat generator that you have assembled yourself.
2. Decide on its dimensions and select a pipe of such a diameter, inside which all these mechanisms would easily fit.
3. Make covers on one side and the other.
4. Ensure the rigidity of the fastening of the internal mechanisms and the ability of the pump to pump water through itself from the resulting reservoir.
5. Make an inlet and attach a pipe to it. The pump should, with its water intake, be located inside as close as possible to this hole.

Weld a flange on the opposite end of the pipe. With it, the cover will be attached through the rubber gasket. To make it easier to mount the insides, make a simple lightweight frame or skeleton. Inside it, assemble the device. Check the fit and tightness of all components. Insert into the case and close the lid.

Connect to consumers and check everything for tightness. If there are no leaks, turn on the pump. By opening and closing the valve, which is located at the outlet of the generator, adjust the temperature.

Generator insulation

Scheme of connecting the heat generator to the heating system.

First you need to make a casing of insulation. Take a sheet of galvanized sheet or thin aluminum for this. Cut out two rectangles from it if you will make a casing from two halves. Or one rectangle, but in such a way that, after manufacturing, Potapov's vortex heat generator, which was assembled by hand, will completely fit in it.

It is best to bend the sheet on a large diameter pipe or use a cross member. Put the cut sheet on it and press the wooden block on top with your hand. With the second hand, press the sheet of tin so that a slight bend forms along the entire length. Advance the workpiece a little and repeat the operation again. Do this until you get a cylinder.

1. Connect it with a lock, which is used by tinkers for drainpipes.
2. Make covers for the casing, providing holes in them for connecting the generator.
3. Wrap the device with thermal insulation material. Using wire or thin strips of tin, fix the insulation.
4. Place the device in the casing, close the covers.

There is another way to increase heat production: to do this, you need to figure out how the Potapov vortex generator works, the efficiency of which can approach 100% and higher (there is no consensus why this happens).

During the passage of water through a nozzle or jet, a powerful stream is created at the outlet, which hits the opposite end of the device. It twists, and due to the friction of the molecules, heating occurs. This means that by placing an additional barrier inside this flow, it is possible to increase the mixing of the liquid in the device.

Knowing how this works, you can begin to design an additional improvement. It will be a vortex damper made of longitudinal plates located inside two rings in the form of an aircraft bomb stabilizer.

Scheme of a stationary heat generator.

Tools: welding machine, angle grinder.

Materials: sheet metal or strip iron, thick-walled pipe.

Make two rings 4-5 cm wide from a pipe of a smaller diameter than Potapov's vortex heat generator. Cut identical strips from strip metal. Their length should be equal to a quarter of the length of the body of the heat generator itself. Select the width so that after assembly there is a free hole inside.

1. Secure the plate in a vise. Hang on it on one and the other side of the ring. Weld a plate to them.
2. Remove the workpiece from the clamp and turn it 180 degrees. Place a plate inside the rings and fasten it in the clamp so that the plates are opposite each other. Fasten in this way at an equal distance of 6 plates.
3. Assemble the vortex heat generator by inserting the device described opposite the nozzle.

Probably, it is possible to further improve this product. For example, instead of parallel plates, use steel wire, winding it into an air ball. Or make holes of different diameters on the plates. Nothing is said about this improvement anywhere, but this does not mean that it is not worth doing.

Scheme of the device of the heat gun.

1. Be sure to protect Potapov's vortex heat generator by painting all surfaces.
2. Its internal parts during operation will be in a very aggressive environment caused by cavitation processes. Therefore, both the body and everything that is in it, try to make it from thick material. Don't skimp on hardware.
3. Make several options for covers with different inlets. Then it will be easier to select their diameter in order to obtain high performance.
4. The same applies to the vibration damper. It can also be modified.

Assemble a small laboratory bench, where you will run in all the characteristics. To do this, do not connect consumers, but loop the pipeline to the generator. This will simplify its testing and selection of the necessary parameters. Since complex devices for determining the efficiency factor at home can hardly be found, the following test is proposed.

Turn on the vortex heat generator and note the time when it heats the water to a certain temperature. It is better to have an electronic thermometer, it is more accurate. Then make changes to the design and run the experiment again, watching the temperature increase. The more the water will be heated in the same time, the more preference will have to be given to the final version of the established improvement in the design.

Ready heat generator.

Depending on the type of device, the method of its manufacture also varies. It is worth familiarizing yourself with each type of device, studying the features of production, before starting work. An easy way to make a Ranke vortex tube with your own hands is to use ready-made elements. This will require any engine. At the same time, a device of greater power is able to heat more coolant, which will increase the productivity of the system.

For a successful construction, ready-made solutions must be found. You can create a vortex heat generator with your own hands, the drawings and diagrams of which will be available, without much difficulty. To carry out construction work, you will need the following tools:

• Bulgarian;
• iron corners;
• welding;
• drill and a set of several drills;
• fittings and a set of keys;
• primer, colorant and brushes.

The vortex motor is one of the sources of alternative energy for home heating.

It should be understood that rotary devices emit quite a lot of noise during operation. But compared to other devices, they are characterized by greater performance. Drawings and diagrams for the manufacture of a do-it-yourself vortex heat generator can be found everywhere. It should be understood that the work will be completed successfully only with full compliance with the production technology.

Installation of the pump of the vortex heat generator and construction of the housing

The casing of this device is made in the form of a cylinder, which must be closed from the sides of each base. Through holes are located on each side. Using them, you can connect a do-it-yourself vortex heat generator to the home heating system. The main feature of such a product is that a jet is installed inside the casing, near the inlet. This device must be selected individually for each individual case.

Scheme of the vortex engine.

The production process includes the following items:

• cutting the pipe of the required size (about 50-60 cm);
• thread cutting;
• making a pair of rings from a pipe of the same diameter with a length of approximately 50 mm;
• welding covers to places where the thread was not cut;
• cutting two holes in the center of each cover (one for connecting the pipe, the second for the jet);
• drilling a chamfer next to the jet to get the nozzle.

The installation of the vortex motor pump is carried out after the selection of the unit of the required power. When buying, you should follow two rules. First, the device must be centrifugal. Secondly, the choice will be appropriate only if the device will function optimally in tandem with the installed electric motor.

Vortex motor insulation

Before putting the device into operation, it should be insulated. This is done after the construction of the casing. It is recommended to wrap the structure with thermal insulation. As a rule, high-temperature resistant material is used for this purpose. The insulation layer is attached to the casing of the device with a wire. As thermal insulation, one of the following materials should be used:

Ready heat generator.

• glass wool;
• mineral wool;
• basalt wool.

As you can see from the list, almost any fibrous thermal insulation will do. A vortex induction heater, reviews of which can be found throughout the Runet, should be insulated with high quality. Otherwise, there is a risk that the device will give off more heat to the room where it is installed. Good to know: " .

At the end, some advice should be given. First - the surface of the product is recommended to be painted. This will protect it from corrosion. Secondly, it is desirable to make all the internal elements of the device thicker. This approach will increase their wear resistance and resistance to aggressive environments. Thirdly, it is worth making several spare covers. They must also have holes of the required diameter in the required places on the plane. This is necessary in order to achieve a higher efficiency of the unit by selection.

Summarizing

If all the rules for manufacturing the structure were taken into account, then the vortex generator will last a long time. Do not forget that a lot in the heating system also depends on the competent installation of the device. In any case, the manufacture of such a design from improvised means will cost less than purchasing a finished device. However, for the optimal functioning of the device, it is necessary to responsibly approach the manufacturing processes of the body and the thermal insulation sheathing.

The Potapov vortex heat generator, or VTP for short, was designed specifically to generate heat energy with just an electric motor and pump. Such a device is used primarily as an economical source of heat.

Today we will consider the design features of this device, as well as how to make a vortex heat generator with our own hands.

Principle of operation

The generator works as follows. Water (or any other coolant used) enters the cavitator. The electric motor then spins the cavitator, in which the bubbles collapse - this is cavitation, hence the name of the element. So all the liquid that enters it begins to warm up.

The electricity required to run a generator is spent on three things:

• On the formation of sound vibrations.
• To overcome the force of friction in the device.
• For heating a liquid.

At the same time, according to the creators of the device, in particular, the Moldavian Potapov himself, renewable energy is used for work, although it is not entirely clear where it comes from. Be that as it may, no additional radiation is observed, therefore, we can talk about almost one hundred percent efficiency, because almost all the energy is spent on heating the coolant. But that's in theory.

What is it used for?

Let's take a small example. There are many enterprises in the country that, for one reason or another, cannot afford gas heating: either there is no mains nearby, or something else. Then what is left? Heat with electricity, but the tariffs for this kind of heating can be terrifying. This is where Potapov's miracle device comes to the rescue. When using it, the cost of electricity will remain the same, the efficiency, of course, too, since it still won’t be more than a hundred, but the financial efficiency will be from 200% to 300%.

It turns out that the efficiency of the vortex generator is 1.2-1.5.

Required Tools

Well, it's time to start making your own generator. Let's see what we need:

• Angle grinder, or impeller;
• Iron corner;
• Welding;
• Bolts, nuts;
• Electric drill;
• Keys 12-13;
• Drills for drills;
• Paint, brush and primer.

Manufacturing technology. Engine

Note! Due to the fact that there is no information regarding the characteristics of the device in terms of pump power, all parameters given below will be approximate.

The easiest option to make a vortex heat generator with your own hands is to use standard parts in your work. Almost any engine can suit us, the more power it has, the more coolant it can heat. When choosing an electric motor, you should first of all consider the voltage in your home. The next step is to create a frame for the engine. The bed is an ordinary iron frame, for which it is better to use iron corners. We will not say any dimensions, since they depend on the dimensions of the engine and are determined on the spot.

1. We cut the squares of the required length with a turbine. We weld from them a square structure of such dimensions that all the elements fit there.
2. We cut out an additional corner and weld it to the frame across so that an electric motor can be attached to it.
3. We paint the bed, wait until it dries.
4. We drill holes for fasteners, we fix the electric motor.

Installing the pump

Next, we must choose the "right" water pump. The range of these tools today is so wide that you can find a model of any strength and dimensions. We only need to pay attention to two things:

• Will the engine be able to spin this pump;
• Is it (pump) centrifugal.

At the vortex generator, the body is a cylinder, closed on both sides. On the sides there should be through holes through which the device will be connected to the heating system. But the main feature of the design is inside the case: a jet is located immediately near the inlet. The jet opening must be selected purely individually.

Note! At the same time, it is desirable that the jet opening be half as large as 1/4 of the total cylinder diameter. If the hole is smaller, then water will not be able to pass through it in the required amount and the pump will start to heat up. Moreover, the internal elements will begin to collapse by cavitation.

To make the case, we need the following tools:

1. An iron pipe with thick walls, about 10 cm in diameter;
2. Couplings for connection;
3. Welding;
4. Several electrodes;
5. turbine;
6. A pair of pipes in which the thread is made;
7. Electric drill;
8. Drill;
9. Adjustable wrench.

Now - directly to the manufacturing process.

1. To begin with, we cut off a piece of pipe about 50-60 cm long and make an external groove on its surface about half the thickness, 2-2.5 cm. We cut the thread.
2. We take two more pieces of the same pipe, each 5 cm long, and make a couple of rings out of them.
3. Then we take a metal sheet with the same thickness as that of the pipe, cut out peculiar covers from it, weld them where the thread was not made.
4. In the center of the covers we make two holes - one of them along the circumference of the nozzle, the second - along the circumference of the jet. Inside the cover next to the jet, we drill a chamfer so that we get a nozzle.
5. We connect the generator to the heating system. we connect the branch pipe near the nozzle to the pump, but only to the hole from where water flows under pressure. We connect the second branch pipe to the inlet to the heating system, while the outlet must be connected to the inlet of the pump.

The pump will create pressure, which, acting on the water, will force it to pass through the nozzle of our design. In a special chamber, the water will overheat due to active mixing, after which it is supplied directly to the heating circuit. In order to be able to regulate the temperature, the do-it-yourself vortex heat generator must be equipped with a special locking device located next to the nozzle. If you cover the constipation a little, then the structure will move water through the chamber longer, therefore, because of this, the temperature will rise. This is how this kind of heater works.

About other alternative heating methods

Increasing productivity

The pump loses thermal energy, which is the main disadvantage of the vortex generator (at least in its described version). Therefore, it is better to dip the pump in a special water jacket, so that the heat emanating from it also benefits.

The diameter of this jacket should be slightly larger than that of the pump. We can use for this, according to tradition, a pipe cut, or we can make a parallelepiped from sheet steel. Its dimensions must be such that all elements of the generator fit freely into it, and the thickness must be such that it can withstand the operating pressure of the system.

In addition, heat loss can be reduced by installing a special tin casing around the device. The insulator can be any such material that is able to withstand the operating temperature.

1. We assemble the following design: a heat generator, a pump and a connecting pipe.
2. We measure what their dimensions are, and select a pipe of the desired diameter - so that all the details can easily fit in it.
3. We make covers for both sides.
4. Next, we make sure that the parts inside the pipe are rigidly fixed, and also that the pump is able to pump the coolant through itself.
5. We drill an outlet, attach a pipe to it.

Note! It is necessary to place the pump as close as possible to this hole!

At the second end of the pipe, we weld a flange, through which the cover will be fixed to the gasket. It is possible to equip a frame inside the case to make it easier to install all the elements. We assemble the device, check how strong the fasteners are, check the tightness, insert it into the case and close it.

Then we connect the vortex heat generator to all consumers, check it again for tightness. If nothing flows, then you can activate the pump. When opening / closing the tap at the inlet, we regulate the temperature.

We warm the VTP

First of all, we dress the casing. For this, we take a sheet of aluminum or stainless steel and cut out a couple of rectangles. It is better to bend them along such a pipe, which has a larger diameter, so that a cylinder is eventually formed. Next, follow the instructions.

1. We fasten the halves together using a special lock used to connect water pipes.
2. We make a couple of covers for the casing, but do not forget that they should have holes for connection.
3. We wrap the device with thermal insulation material.
4. We place the generator in the casing and tightly close both covers.

There is another way to increase productivity, but for this you need to know exactly how Popov's miracle device works, the efficiency of which can exceed (not proven and not explained) 100%. We already know how it works, so we can proceed directly to improving the generator.

Whirlpool damper

Yes, we will make a device with such a mysterious name - a vortex damper. It will consist of plates arranged along the length, placed inside both rings.

Let's see what we need to work.

• Welding.
• Turbine.
• Steel sheet.
• Pipe with thick walls.

The pipe must be smaller than the heat generator. We make two rings out of it, about 5 cm each. From the sheet cut out several strips of the same size. Their length should be 1/4 of the length of the device body, and the width should be such that after assembly there is free space inside.

1. We insert a plate into a vise, hang metal rings on one end of it and weld them to the plate.
2. Remove the plate from the clamp and turn the other side. We take the second plate and place it in the rings so that both plates are placed in parallel. Similarly, we fix all the remaining plates.
3. We assemble the vortex generator with our own hands, and install the resulting structure in front of the nozzle.

Note that the field of improving the device is almost limitless. For example, instead of the above plates, we can use steel wire, twisting it first in the form of a ball. In addition, we can make holes in plates of various sizes. Of course, all this is not mentioned anywhere, but who said that you cannot use these enhancements?

Finally

And as a conclusion - a few practical tips. Firstly, it is desirable to protect all surfaces with staining. Secondly, all internal parts should be made of thick materials, since it (the parts) will constantly be in a fairly aggressive environment. And thirdly, take care of several spare caps with different hole sizes. In the future, you will select the required diameter in order to achieve maximum performance of the device.

The main task of the Potapov vortex heat generator (VTP) is to obtain thermal energy using an electric motor and a pump. Due to the high savings, the device has received great demand in the market.

Principle of operation

Water or another coolant is fed into the cavitator, with the help of an electric motor, the cavitator is untwisted, which gives the collapse of the bubbles inside, this process is called cavitation, and all the liquid that has entered it is heated.

The energy that is needed to run the generator is used to perform three functions:

• To convert sound vibrations;
• To overcome the friction force in the device;
• For heating a liquid.

Scheme of connection of the vortex heat generator

1 - pumping unit; 2 - jet apparatus; 3 - heat exchanger;
4 - circulation pump; 5 - heating system; 6 - expansion tank.

According to the creators of the unit and even Potapov himself, the operation of the device is based on renewable energy, although it is not entirely clear where it comes from. In any case, due to the fact that there is no additional radiation, it is theoretically possible to talk about almost one hundred percent efficiency, since the vast majority of energy is spent on heating the coolant.

For example:

The state has a number of enterprises that, for a number of reasons, do not use gas heating. What to do? Alternatively, you can use electric heating, however, due to high tariffs, this type of heating will not always be acceptable.

Potapov's device, in this situation, will be the most effective. The fact is that its operation will not increase your energy costs in any way, and the efficiency will also not be higher than 100%, but regarding the financial efficiency, it will increase by 200% - 300%. This clearly demonstrates the efficiency of the vortex generator of the order of 1.2-1.5.

Tools and materials

• Angle grinder or impeller;
• Metal corner;
• Welding machine;
• Bolts, nuts;
• Electric drill;
• Drills for a drill;
• Key for 12 and 13;
• Primer, brush and paint.

Manufacturing

It's important to know!!! Since there are no pump power parameters as such, the parameters discussed below will be approximate.

For the manufacture of a vortex heat generator, an engine will be required on its own, the power of which will be the greater, the better, due to the fact that it can heat a larger amount of coolant. Of course, you should focus on the voltage in your home or room. After you have decided on the engine, you need to make a frame for the engine. The bed will look like an ordinary iron frame, on which ordinary iron corners will be used.

With regards to the size of the frame, it all depends on the size of the engine. Using a turbine, you need to cut the squares of the desired length and weld a square structure out of them, the dimensions of which should allow you to accommodate all the elements. Next, you need to cut an additional corner and attach it to the frame across, since an electric motor will need to be attached to it. Next, paint the frame and drill holes for fasteners, and then fix the electric motor.

Pump installation

When choosing a water pump, you should pay attention to this:

• Is it a centrifugal type of pump;
• Will the engine be able to spin this pump.

As for the pump model and manufacturer, there are no restrictions. After that, the pump must be fixed in the same frame, if necessary, additional fasteners can be used.

Hull design

The device has a cylinder-shaped body, which is closed on both sides. The device is connected to the heating system through through holes on the sides. However, the main feature of the device is the jet, which is located inside the structure directly near the inlet. The diameter of the jet hole is again selected individually.

Important!!! So that the diameter of the orifice of the jet is half that of 1/4 of the total diameter of the cylinder. In the case of a very small size, water in the required amount simply cannot pass through it, and the pump will heat up. Also, cavitation will have a destructive effect on internal parts.

Materials and tools to make the case

• Iron pipe with a diameter of 10 cm and thick walls;
• Couplings;
• Welding machine;
• electrodes;
• turbine;
• A pair of threaded pipes;
• Electric drill with drills;
• Wrench.

Manufacturing process

First of all, you should cut off a piece of pipe, the length of which will be about 50-60 cm and on its surface it will be necessary to make an external groove of 2-2.5 cm, as well as cut the thread. Next, you will need to take two more pieces of this same pipe, 5 cm each, and make a couple of rings out of them. After that, you will need to take a sheet of metal the same thickness as the pipes and cut out a kind of cover from it. Further, these covers will need to be welded in those places where there is no thread. In the center of the covers, two holes will need to be made, the first should be made around the circumference of the nozzle, while the second should be made around the circumference of the jet.

From the inside of the cover next to the jet, it is necessary to drill a chamfer in order to get a nozzle. Then you can connect the generator to the heating system. The nozzle near the nozzle must be connected to the pump, though only to the hole from where water flows under pressure. The second branch pipe must be connected to the inlet to the heating system. The output is connected to the pump inlet. As a result of the pressure created by the pump, water will pass through the nozzle of the structure. The water heated by mixing in a special chamber will be supplied to the heating circuit. To adjust the temperature, the device is equipped with a special locking mechanism, which is located next to the nozzle. If you slightly cover the constipation, the water will pass at a slower speed through the chamber, as a result of which its temperature will increase.

How to increase device performance

As a result of the loss of thermal energy by the pump, the efficiency of the device drops, this is the main disadvantage. To combat this phenomenon, it is recommended to dip the pump in a special water jacket, so that the heat from it will be beneficial. The diameter of this jacket should be slightly larger than that of the pump. For these purposes, a pipe segment can be used, or maybe a parallelepiped made of sheet steel. In terms of dimensions, it must be such that all elements of the generator can fit into it, and the thickness must withstand the working pressure of the system.

Reducing heat loss can also be achieved by installing a special tin casing around the device. A variety of materials can be used as an insulator that can withstand high temperatures. To assemble a structure consisting of a heat generator, a pump and a connecting pipe, it is necessary to measure their diameters, select a pipe of the required diameter so that all elements can fit in it.

After that, you need to make covers that are fixed on both sides. All parts inside the pipe must be securely fixed for the pump to pump the coolant through itself. Next, you need to drill an outlet hole and securely fix the pipe on it. The pump must be fixed as close as possible to this hole. A flange should be welded to the second end of the pipe, with which to fix the cover on the gasket seal. Also, a frame can be equipped inside the case, on which it will be possible to mount all the elements. Next, you should assemble the device, check the strength of its fasteners, tightness, insert into the case and close. If there is no leakage, adjust the temperature when opening/closing the inlet tap. Insulate the VTP.

You may be interested in information about building a solar collector yourself. We make a casing from a sheet of aluminum or stainless steel, after we cut out two rectangles, we bend them along the pipe until cylinders are formed. The halves are interconnected by a special lock, which is used to connect water pipes. It is necessary to make a couple of holes for the casing and leave holes for connection. Wrap the device with thermal insulation, and place the generator in the casing, while closing the covers tightly.

Another way to improve the performance of the ECP is to create a vortex damper

For these purposes, it will be necessary to use: welding, an impeller, a sheet of steel, a pipe with thick walls. The dimensions of the pipe must be smaller than the dimensions of the heat generator. From it you need to make two rings, each 5 cm long, cut several strips from the sheet.

It is necessary to insert a plate into a vise and hang metal rings on one end of it, which are welded to the plate. Next, you should take out the plate and turn it on the other side, take the second plate and place it in the rings so that the plates are parallel. We do the same procedure with all the plates. After that, the vortex generator should be assembled, and the structure should be placed opposite the nozzle.

The most effective way to deal with water hammer is to smoothly turn the water on and off. And this is true not only for industry, but also for ordinary users; to modernize the system, which implies the installation of special shock-absorbing devices in the direction of water movement. This means that the part of the pipe that is located in front of the thermostat is changed to plastic. As a rule, the length of this ...

Unfortunately, water hammer in water supply systems is far from uncommon and most people know about it. However, not everyone is aware of the danger of hydraulic shocks and the danger they carry, due to the fact that this is fraught not only with equipment failure, but also with the appearance of cracks and deformation of pipes. In order to avoid negative consequences, it is necessary to clearly ...

Connecting the device to hot water pipes is regulated by SNiP. In the case of installing a new device, you will have to attach pipe sections to the pipeline, and a coil directly to them. The connection procedure itself does not present any difficulties at all. For these purposes, you just need to connect the ends of the PP pipes with a soldering iron. Connecting the ends of PP pipes when installing a new ...

The high cost of heating equipment makes many people think about whether it is worth buying an industrial model or is it better to assemble it yourself. In fact, the heat generator is a somewhat modified centrifugal pump. To assemble such a unit on their own is within the power of someone who has minimal knowledge in this industry. If there are no own developments, then ready-made schemes can always be found on the net. The main thing is to choose one by which it will be easy to assemble a heat generator with your own hands. But first, it does not hurt to learn as much as possible about this device.

What is a heat generator

Equipment of this class is represented by two main types of devices:

• Stator;
• Rotary (vortex).

However, not so long ago, cavitation models also appeared, which may soon become a worthy replacement for units operating on conventional fuels.

The difference between stator and rotary devices is that in the first, the liquid is heated using nozzles located at the inlet and outlet of the unit. In the second type of generators, heat is generated in the process of pump revolutions, leading to water turbulence.

Watch the video, the generator in operation, measurements:

In terms of performance, a do-it-yourself vortex heat generator is somewhat superior to the stator one. It has 30% more heat dissipation. And although today on the market such equipment is represented by various modifications that differ in rotors and nozzles, the essence of their work does not change from this. Based on these parameters, it is better to assemble a heat generator on your own with a vortex type. How to do this will be discussed below.

Complete set and principle of operation

The simplest design has a device consisting of the following elements:

1. Rotor made of carbon steel;
2. Stator (welded or monolithic);
3. Clamping sleeve with an inner diameter of 28 mm;
4. Steel ring.

Let us consider the principle of operation of the generator using the cavitation model as an example. In it, water enters the cavitator, after which it is spun by the engine. During the operation of the unit, air bubbles in the coolant collapse. In this case, the liquid that has entered the cavitator is heated.

For self-assembled work, using the drawings of the device found on the network, it should be remembered that it requires energy, which is spent on overcoming the friction force in the device, the formation of sound vibrations, and heating the liquid. In addition, the device has almost 100% efficiency.

Tool required to assemble the unit

It is impossible to assemble such a unit from scratch on your own, since for its manufacture it will be necessary to use technological equipment, which the home master simply does not have. Therefore, with their own hands, they usually assemble only an assembly that in some way repeats. It is called the Potapov device.

However, even to assemble this device, equipment is needed:

1. Drill and a set of drills for it;
2. Welding machine;
3. grinding machine;
4. Keys;
5. fasteners;
6. Primer and paint brush.

In addition, you will need to purchase a motor powered by a 220 V network and a fixed base for installing the device itself on it.

Generator manufacturing steps

The assembly of the device begins with the connection to the pump, the desired pressure type, the mixing nozzle. It is attached using a special flange. A hole is made in the center of the bottom of the pipe through which hot water will be discharged. To control its flow, a braking device is used. It is in front of the bottom.

But since cold water also circulates in the system, its flow must also be regulated. To do this, use a disk rectifier. When the liquid cools, it goes to the hot end, where it is mixed with the heated coolant in a special mixer.

Next, they proceed to the assembly of the design of the vortex heat generator with their own hands. To do this, I use a grinder to cut squares from which the main structure is assembled. How to do this can be seen in the drawing below.

There are two ways to assemble the structure:

• Using bolts and nuts;
• With a welding machine.

In the first case, get ready for the fact that you have to make holes for fasteners. This requires a drill. During the assembly process, all dimensions must be taken into account - this will help to obtain a unit with the specified parameters.

The very first stage is the creation of a frame on which the engine is installed. It is collected from iron corners. The dimensions of the structure depend on the size of the engine. They may differ and are selected for a specific device.

To fix the engine on the assembled frame, you will need another square. It will act as a cross member in the structure. When choosing an engine, experts recommend paying attention to its power. The amount of heated coolant depends on this parameter.

We watch the video, the stages of assembling the heat generator:

The last stage of assembly is painting the frame and preparing holes for installing the unit. But before proceeding with the installation of the pump, its power should be calculated. Otherwise, the engine may not be able to start the unit.

After all the components are prepared, the pump is connected to the hole from which water flows under pressure and the unit is ready for operation. Now, using the second pipe, it is connected to the heating system.

This model is one of the simplest. But if there is a desire to regulate the temperature of the coolant, then a locking device is installed. Electronic control devices can also be used, but it should be borne in mind that they are quite expensive.

Connecting the device to the system is as follows. First, it is connected to the hole through which water enters. She is under pressure. The second branch pipe is used for direct connection to the heating system. To change the temperature of the coolant, a locking device is located behind the nozzle. When it is closed, the temperature in the system gradually increases.

Additional nodes may also be used. However, the cost of such equipment is quite high.

Watch the video, the design after manufacturing:

The body of the future generator can be made welded. And the details for it according to your drawings will be machined by any turner. Usually it has the form of a cylinder, closed on both sides. Through holes are made on the sides of the body. They are needed to connect the unit to the heating system. A jet is placed inside the case.

The outer cover of the generator is usually made of steel. Then holes for bolts and a central one are made in it, to which a fitting for supplying liquid is subsequently welded.

At first glance, it seems that there is nothing difficult in assembling a heat generator with your own hands on wood. But in fact, this task is not so easy. Of course, if you do not rush and study the issue well, then you can handle it. But at the same time, the accuracy of the dimensions of the machined parts is very important. And the manufacture of the rotor requires special attention. Indeed, if it is machined incorrectly, the unit will work with a high level of vibration, which will negatively affect all the details. But the bearings suffer the most in this situation. They will break very quickly.

Only a properly assembled heat generator will work efficiently. At the same time, its efficiency can reach 93%. Therefore, experts advise.
