Submersible well pump with automation: an overview of the best models. Automatic submersible pump: varieties, features, installation

Most suitable option uninterrupted water supply in the absence of centralized water networks is a pump and a well drilled on a household plot, or a well. Quite often, homeowners purchase a lightweight and productive automatic submersible pump, capable of raising water by 5-10 meters, which in most cases is quite sufficient. But this is not the limit, the depth of the well can reach several tens of meters.

Manufacturers also produce submersible pumps for pumping sewage and drainage at the household level. The complete set of any type of pump is accompanied by an instruction that indicates the purpose of the equipment and its technical characteristics. If you decide in advance on the purpose of acquiring a pump and calculate its power, then there will be no difficulties with choosing a device.

Varieties and features of submersible pumps

There are two main types of submersible pumps:

• vibration, working on the principle of reciprocating piston movement;
• centrifugal, creating pressure with the help of blades due to centrifugal force.

Pumping equipment is different:

• by power;
• by performance;
• by depth of immersion;
• by the height of the water supply;
• according to the diameter of the body;
• according to the material of manufacture;
• along the length of the cord.

Depending on the operating conditions and purpose, submersible pumps are divided into four groups. All of them belong to pressure equipment. Automatic models are equipped with float switches that stop the operation of the unit if the water in the well or well drops to a critical level.

The models are distinguished by a cylindrical body shape, which has a small diameter, which implies their placement and operation in deep wells, tanks, tanks, etc. The body is usually made of of stainless steel which increases the life of the equipment. Thanks to additional components, trouble-free operation of the mechanism is ensured, and the presence of a protective cover prevents mechanical damage to the device.

Borehole pumps are equipped with filters that do not allow suction of contaminants and various impurities. In this regard, this equipment is widely used for pumping water from reservoirs. The high pressure submersible pump is equipped with an integrated system electronic control and gives stable indicators of water supply.

Quite often, wells become the only alternative for water supply. suburban area, especially in the case of deep ground water, and downhole pumps are one of the options for raising it to the surface. They are also used for irrigating fields in agriculture and in fire protection systems.

When choosing a borehole pump, experts recommend paying Special attention to its diameter. It must be at least 10mm smaller than the casing to prevent jamming.

Installing a pump in a well

Before starting installation work, it is necessary to visually check all current-insulating units and elements of the borehole pump. In particular, this applies to the electrical cable and the place of its docking with the body. High-pressure submersible pumps do not need to be initially filled with water, so they can be turned on immediately after being immersed in the well.

Vibrating models are securely fixed with a reinforced or made of stainless steel cable, which ensures reliable fastening throughout the required service life.

To prevent foreign debris from getting inside the well and interfering with the operation of the pump, the pipe is protected by a head.

Experts recommend in the case of operation of a borehole pump in winter time expand the well to a depth of 2.5-3m and install a well, and supply to the house water pipes lay in the trench. This solution will protect them from freezing and rupture at sub-zero temperatures.

2. Well pumps

This pumping equipment is designed for pumping clean drinking water with minimal contamination. It is widely used in cottages or with little water consumption. The difference between well pumps is:

• operation at shallow depth;
• impossibility of installation on the bottom of the well.

It should be borne in mind that models designed to work in wells are equipped with filters that can easily become clogged in dirty water. Therefore, their operation in conditions where sediment can rise and be sucked from the bottom is not allowed, as the equipment will fail too quickly, and the manufacturer's warranty will lose its relevance.

Installing a pump in a well

Well submersible pumps are fastened with reliable reinforced cables. Depending on the characteristics and model, the units are either partially lowered into the water, or completely. In any case, they are installed in compliance with the required distance to the bottom surface of the well, which is at least 0.5-1 m. This is done so that the pump cannot suck in particles of silt or sand.

3. Drainage pumps

During a period of intense snowmelt or heavy rains, many homeowners face seasonal problems, one of which is flooding of the site. In connection with the melting of snow, the spill of a nearby river during a flood or a prolonged downpour, the following may occur:

• flooding in basements and underground cellars;
• fluid accumulation in pits, lowlands and ditches.

deal with emergency a submersible drainage pump will help. It is able to cope with water containing particles up to 30 mm in size. Drainage equipment is also used in the event of a pipeline rupture, when irrigating farmland, watering garden plots and home gardens.

Drainage pumping equipment may be installed directly on the surface from which contaminated water is pumped out. With its help, it is quite possible to drain any flooded room in the absence of additional water flows.

4. Fecal sewage pumps

The main purpose of fecal pumping equipment is the removal of sewage from cesspools and liquid domestic wastewater. The design of the device is similar to drainage pumps, but have high rate capacity to cope with the larger size and quantity of particles of impurities in the effluents.

From pollution and blockages fecal pumps the design of the equipment itself protects, including wide flow channels.

Centrifugal pumps are installed in all types of wells, however, not all water pumping devices have similar characteristics and are equally well suited to a certain type of well.

Autonomous water supply systems of a private house function thanks to pumps that are installed directly in a well or well and provide water to the house. Currently, a popular type of water intake equipment for the private sector is a submersible well pump with automation, which is powered by electricity and produces an uninterrupted supply of water to the system.

The choice of model is a crucial moment in the arrangement of a well or well, because. the performance of the water supply system in the house, the frequency of maintenance and repair of equipment, and its service life depend on this.

There are three main types of submersible pumps for autonomous fluid supply:

• with built-in automation;
• with check valve;
• vibration;
• centrifugal.

A common advantage that any deep well pump has is high efficiency: each kilowatt of electricity consumed provides the user with the maximum possible amount of water in the tap (compared to surface models). Other advantages of this type of technology include:

• no noise during operation;
• frost protection in winter;
• stable operation (failures and malfunctions occur quite rarely).

Today automatic operation water intake equipment in the private sector - the standard of quality and ease of use. Automation not only provides a constant supply of water, but also protects the device from overheating and turns it off when shallowing (at "idle").

There are two ways to automate equipment: electronic and hydropneumatic. Electronic automatic pumps that have a built-in control unit in the piping or device housing - preferred view water intake equipment. Such automation has more a simple circuit and the principle of operation, differs in reliability and the smaller sizes. Hydropneumatic automation submersible wells is a system of a pressure switch and a hydraulic accumulator, with the help of which the pressure is regulated directly in the tank and pipeline.

Choosing the right well pump

In order to choose the right automatic pump for a well or a well, it is necessary to take into account the basic parameters of equipment operation. It is important to distinguish between models for a well and a well - these sources have fundamental differences, influencing the choice of units for supplying liquid to the water supply system. Well pumps, as a rule, have a larger diameter casing than well pumps, which causes more simple design models. Be sure to have an internal engine cooling system.

Whereas in borehole pumps cooling is carried out by the flow of water between the walls of the well and the engine, then the models for the well require a different method of cooling. Since the distance from the unit to the walls of the well is quite large, the engine is protected from overheating from the inside with the help of the pumped liquid. Additional protection from overheating well wells is a special float mechanism that prevents the equipment from idling.

Principles for choosing a submersible pump

The principle of selecting a model of equipment for water supply to a greater extent depends on the technical parameters of the water supply system to the house, and to a lesser extent - on the depth and location of the water horizon of the well / well. The purchase of a submersible pump is influenced by two main parameters:

• volume of water consumption;
• distance from home;
• chemical composition of water and its physical characteristics.

The volume of water consumption in the house is a basic parameter that affects the choice of model. The greater the need, the more productive and powerful the unit should be.

Fig.1 Hydraulic accumulator device

It is preferable to use models with hydraulic accumulators that have a reservoir. This allows the equipment not to work constantly, which will reduce electricity consumption. The volume of water is constantly renewed as it is consumed due to the difference in air pressure in membrane tank. When the pressure in the tank drops, a relay is automatically activated, turning on the unit.

The capacity of the hydraulic accumulator, chosen correctly, will provide consumers necessary quantity water in the house. For permanent consumption (when living in a house or cottage all the time), you need to purchase a hydraulic accumulator from 50 liters. Suitable for seasonal living in the country compact model up to 10 liters.

The more the well or well is removed from the house, the more power the pump needs to constantly draw water and maintain a stable pressure in the system. If the source is within 20 meters of the object, then you can choose any model of the unit. When the house is located up to 50 meters from the well, it is necessary to look for a model with a water rise height of up to 20 meters. If the distance of the well from the house is 50 meters or more, then the height of the water rise specified by the manufacturer must be at least 40 meters.

Choosing a Vibrating Pump

The chemical composition of water and, to a greater extent, its physical characteristics, also influence the choice of a submersible pump model. The more insoluble impurities, suspensions and solid particles in the water, the more vulnerable the technique becomes. Typically, manufacturers and service companies for the installation of autonomous water supply systems recommend additionally installing filters in wells. But at even they cannot completely remove all mechanical impurities.

Fig.2 Vibration pump device

The more foreign particles are in the well or well, the simpler the device should be. Optimal choice- a vibration pump for a well, which works by changing the water pressure in the injection chamber of the unit. Water is supplied to the tank due to reciprocating movements (vibration) of the rubber diaphragm due to the constant magnetization-demagnetization of the motor core.

Popular brands of submersible pumps

Various domestic and foreign manufacturers are represented on the market of water intake equipment for the private sector. Russian popular brands are not inferior to foreign ones in terms of reliability, but they also have significant advantage– they are adapted to the quality of water and electricity supply in Russian conditions. The most popular brands of pumps are Grundfus, Aquarius, Gileks. The former are in high demand among consumers due to their high technical and performance characteristics- engine power, performance. However, the cost of such devices is somewhat higher: average price is 25-28 thousand rubles (automatic models), and 3-4 thousand rubles (vibration). More affordable, but not inferior in terms of basic technical parameters to the Gileks pump, the cost of which, depending on the model, can vary from 7 to 10 thousand rubles for vibration models and up to 20 thousand for devices with automation.

If you are not sure which pump is right for your well, enlist the help of a consultant. An experienced specialist should know all the basic and secondary parameters that affect the choice of model. Do not choose too cheap or expensive models. It is better to give preference to the "golden mean" from domestic manufacturer. The quality of such equipment is good, and the cost is not too high due to the big name, like the models of foreign brands.

Those who prefer to relax outside the city understand that the pump cannot work without interruptions. This leads to rapid wear of the equipment. But water is needed almost constantly. It is for this reason that it was developed pumping station. It can easily withstand heavy loads for a long period of time.

The principle of operation of a submersible outdoor station is that it is used mechanical device, which changes the level of pressure in a sealed system, due to which there is a directed movement of the water flow. All stations are equipped with a filtration system.

Peculiarities

All manufacturers claim that submersible pumping stations have their own specific features. These include:

• the distance from the pumping station to the well is about 20 meters, while minimum depth catchment well - 4 meters;
• the installation location depends on the type of equipment. The station can be mounted directly in inner part well or installed outside it.
• when mounting, use only high-strength material that is not susceptible to rust or a sharp drop in temperature. This is especially true for the platform.

When using pumping stations, the user may encounter the following troubles:

• the pumping station does not pump water from the well - this moment indicates that the integrity of the system has been violated. Also, the cause of equipment failure may be a malfunction of the mechanism or a decrease in pressure in one of the sections of the system.
• the pumping station stopped turning on in the well - this happens when part of the system is damaged. The reason for this may be the effects of an internal type or external (a sharp drop in temperature).

Attention! Do not install a pumping station in a well in the winter season. this will not allow you to configure the system to normal mode, and low temperatures have a negative impact on the functionality of the structure.

How to choose?

When choosing necessary equipment should focus on the power characteristics of the product.

It is also worth paying maximum attention technical features And functional characteristics element.

When choosing a pump for a well, small-sized systems are preferred. But in the case of water supply, it should be given to larger and more powerful equipment. It will have to last a long period of time and provide the inhabitants of the house necessary volumes water.

Before buying, you should consult with the seller of the consultant, only he will tell you about the throughput of the product and about its technical capabilities. It will also be much easier to weed out all unnecessary and get a unique device for working with plumbing.

Kinds

Depending on the type of installation and method of control, all pumping stations can be divided into three large groups:

• a pumping station with a submersible pump for a well is a device that meets high quality standards and has an operating period many times longer than the direct immersion of the entire system;



• submersible pumping station for a well with automation - in this case, the work takes place in automatic mode. There is no need to constantly adjust the activation and deactivation of the system. All that is required is to expose required indicators on the case using special handles and buttons.



• sewer pumping station with a dry well - in this case, the installation will require the services of a wizard. Only he can do everything installation work without any work or error.



Installation

To install the installation pump type personally, you will need to use a special scheme. Only a visual representation will allow you to correctly position all the elements of the system and prevent the formation of impassable and hard-to-reach system segments.

It is very important to carefully follow the proposed scheme. In the future, this will help to significantly simplify the repair of the pumping station in the well.

How to connect?

For correct connection pumping station to the well should use a specially created instruction:




To prevent the user from encountering additional problems during the connection process, use the video below:

The most important task of a submersible pump is uninterrupted operation under water, therefore corrosion resistance and electrical safety are the main criteria when choosing it. The device has such advantages as ease of installation, high efficiency, compactness and noiselessness.

But what is the difference between different models of submersible devices, and what to look for when buying them?

Types of pumps

Regardless of the type of submersible products, the main purpose of their work is to deliver water from the source to the taps, however, the principles of operation of different types of pumps are very different.

Submersible pumps are divided into two main types:

• Centrifugal. The gear, or, in other words, the impeller, is responsible for the presence of water pressure in this type of device. When the electric motor is turned on, it begins to spin inside the chamber, which has an effect on the water flow rising through the hose.
• Vibrating. In these pumps, the piston is responsible for the pressure. The magnetic coil inside the device is magnetized and demagnetized (about a hundred times per second), which creates a kind of vibration - that's why the devices are called vibrational. When the coil attracts the piston, the pressure in the working compartment decreases and water enters there, and as soon as the pressure rises again, it rushes into the water pipe.

Positive and negative sides of pumps




Centrifugal pumps

This type of submersible devices is much more powerful and productive than vibration counterparts. The pumping of liquid not contaminated with small particles guarantees a long service life of five years. However, the presence in it of solid particles with a diameter of one or two millimeters greatly reduces this figure. And in the case when their size exceeds three millimeters, the product may even break down, and after all, repairing the device can cost a pretty penny.

• The average cost of centrifugal models of the device on the market is seven thousand rubles.

Vibratory pumps

This kind submersible device more resistant to the presence of contamination in the liquid: the presence of solid particles with a diameter of up to two millimeters does not negative impact on the parameters of reliability and durability of the device. But stony particles with a diameter of three to six millimeters reduce the life of the product by more than ten percent. However, it is not difficult to replace a damaged valve or piston yourself.

• The average cost of vibration models is about two thousand rubles.

What to look for when buying a pump



Pump performance (number of pumped cubic meters liquids in one hour) - very important technical specifications. You should also pay attention to the height of the liquid rise. Usually the package contains all necessary information about the product.

If the depth of the well is from five to twenty meters, then which pump you buy will not really matter. With a well depth of twenty to fifty meters, care must be taken to purchase a device whose liquid rise height will be more than twenty meters. If the bottom of the source is at a depth of fifty meters or more, then this parameter should not be less than forty.

In the case when water goes to the tank under the roof of the house, the height of the object relative to the ground (about five to ten meters) is added to the parameter.

• In a clean and well-groomed well, absolutely all models of pumping devices can be used without any problems. A well that has never been cleaned or repaired requires the use of exclusively vibrating varieties of the device.

Both types of water pumping devices are sold in variations that take into account both the upper and lower methods of pumping liquid from the well. The lower water intake is only available for appliances with high performance. Due to the increased power, such models do not overheat, due to a decrease in the amount of water in the source. Most the best way– purchase of a device equipped with top type fluid intake.

If the liquid level drops, the product will not be damaged because automatic control cut off power to the pump immediately.

A little about pumping automation



When the liquid reaches a critical point, the device begins to overheat, because the mechanical parts of the device are cooled due to the transfer of thermal energy to the water in which they are located. If the volume of fluid in the well continues to decrease, then the centrifugal submersible will begin to run in what is known as a "dry" mode, which will cause irreparable damage to its bearings.

Many models have a built-in sensor that detects overheating of the system. If the temperature rises above the normal value, the current supply is blocked.

Device security requires automatic protection mechanical and electrical nature. Automatic data control system in submersible pumping equipment is provided by:

• water pressure sensors in the pipeline;
• liquid level sensors;
• measuring instruments that control the "dry run";
• control blocks;
• complex blocks that include several objects at once.

The principle of operation of electric protection against lowering the water level

Work mode centrifugal pump implies the consumption of a considerable amount of current. Its strength is affected by the density of the pumped liquid - than more density the more electricity is consumed. If the volume of water in the well decreases, air enters the working compartment of the pumping equipment, as a result of which the current strength is reduced by a factor of two. A sensor that measures the “dry run” monitors the current value, and when its strength decreases, it turns off the power.

• The vibration type pump functions differently, for this reason other types of auto-protection are used for it.

Another kind of electrical protection against a decrease in the volume of liquid in the source is based on the fact that water and air have different electrical conductivity. Electrodes are lowered inside the well, while their lower ends are located five centimeters higher than the critical mark. The submersible will be de-energized without manual intervention, preventing overheating and prolonging safe operation.

The principle of operation of mechanical protection against lowering the water level

Protection is provided by a plastic float, which is connected to the measuring device through a thin nylon line. As soon as the liquid level drops to a critical level, set by the length of the nylon line, the measuring instrument signals this to the control system, which will turn off the device. As soon as the volume of water returns to normal, the system will turn on the pumping unit again.

The principle of operation of the water pressure sensor

If the volume of liquid in the source drops, the pumping tube begins to suck in air, which leads to a drop in pressure inside the hose. The measuring instrument reacts to this process and turns off the submersible device. Such sensors are used to protect all types of well pumps.

The principle of operation of automatic regulation of mains voltage

If the voltage in the device rises or falls, even by twenty volts, then the wear process will increase by more than ten percent. A difference of forty volts will add an additional forty percent to this indicator. Therefore, in order not to spoil an expensive product, the voltage value should be equalized using stabilizers operating with an inductive load.

Advantages of automatic submersible pumps



Pumping stations

The volume of accumulators of these devices is five to ten liters, which means that when you bathe, wash clothes or wash dishes, the device will turn on up to six times per minute. Because of this operating mode device life is reduced. Also, the pumping station cannot lift liquid from a level below nine meters.

Semi-submersible pumps

In terms of automation, submersible and semi-submersible pumps are no different, which cannot be said about the price. The cost of submersible vibratory devices is ten times less than semi-submersible ones, and centrifugal devices are three to five times less. Installation and repair of submersible pumps is much easier. In general, semi-submersible pumps have only one advantage: they increase the volume of pumped water by more than one and a half times. This will be effective when more than five cubic meters of water are consumed, which avoids its deficiency. If the water consumption is less than this indicator, then the use of a semi-submersible device is not beneficial in terms of economy.

Type of pumping device and automatic systems should be chosen based on source contamination parameters, level and volume of fluid consumption. A site where the water resource is consumed less than one cubic meter per day should be equipped vibration pumps. They are inexpensive, and their repair and maintenance do not cause problems. If the water consumption is one to four cubic meters per day and the distance to the source is more than fifty meters, then buy centrifugal pumps.

The most popular models of submersible pumps



Submersible well pumps from a variety of manufacturers are on the market. Consider the most popular brands:

• "Baby" - this device can provide stable access to water to a small suburban housing or plot of land. Summer residents appreciate this product for its affordable price and reliability.
• "Brook"- one of best brands in terms of price-quality. Renowned for its flawless performance.
• "Aquarius"- the devices of this brand are based on a simple, but robust design. For the manufacture of pumps used corrosion-resistant materials of high quality.
• "Jileks"- submersible automatic pumps of this brand incorporate special control units. Based on the pressure in the water supply, the pump starts or stops.
• Grundfos- manufacturers produce pumps that work perfectly in water containing impurities and other contaminants. Pumps of this brand are compact and durable.
• "dab"- devices of this brand are specially designed for automatic pumping of liquid from a source. The devices are equipped with means for measuring pressure and water level. There is also an electromechanical control.

If you become the owner of centrifugal pumping equipment, then carefully follow the operating rules, otherwise there is a risk of an oil film in the source, which requires large material costs to remove it.

Another disadvantage of this product is the need to lay a power line from the house to the well, which will provide the device with access to the network.

On the market, you can purchase pumps whose body is made of plastic; in terms of corrosion resistance, they are no worse than any stainless steel models.
