Warranty repair of pumps fork service center. Wilo service

When the equipment breaks down, its owner, who for one reason or another does not have time to deliver the broken unit to the service center, independently determines the cause of the breakdown, calls a familiar lone master, reports the malfunction and asks to come to repair or replace the part . Perhaps such a repair will be able to restore the performance of the equipment, but for how long? It is likely that after a while the unit will fail again, and already due to another breakdown. What's the matter? In the absence of comprehensive diagnostics, which allows not only to determine the specific cause of the malfunction, but also to assess the general condition of the equipment. And if the owner does not realize the importance of diagnostics in time, then he will spend money “down the drain”, scolding the manufacturers of equipment for its poor-quality manufacture and feeling sorry for himself.

The heart of any heating system is the circulation pump, which is responsible for the forced movement of water in the system. To minimize energy costs and at the same time create comfortable temperature conditions in a residential area, they buy Wilo pumps.

Ensuring their efficient and reliable operation, extending the service life occurs through compliance with operating rules, timely maintenance. If the owner ignores these requirements, equipment malfunctions will inevitably occur. Their elimination in the case when the warranty period has expired is often done by hand.

1 Design and technical features

Vilo pumps significantly increase the efficiency of the heating system and the heat transfer of the coolant. Their use makes it possible to use pipes with a smaller cross section when assembling the line, which will reduce fuel costs, reduce carbon dioxide emissions, and make it possible to achieve savings without losing the quality of operation. This is achieved through a properly thought out and developed design, designed for continuous operation.

The Wilo pump consumes no more than 250 W per day, the operation is silent, since there is no fan and similar technical elements that produce noise. There are two types of circulating equipment on sale - with a dry and wet rotor. The latter are used in the installation of heating systems, as a rule, inside small buildings. The difference also lies in the power and volume of the pumped medium. The weakest model is able to make the heating system more efficient on an area of ​​200 sq.m.

Powerful is designed for heating buildings, the area of ​​​​which reaches 1000 sq.m. Both the one and the other unit has the most simplified design and small dimensions. The technical characteristics regarding the head height make it possible to raise water from 8 meters at a flow rate of 5 m3/h.

Distinctive features are the strength and corrosion resistance of the Wilo pump material. For example, the body is cast iron, the shaft located inside it is stainless steel. Its fastening is possible thanks to graphite bearings. The water flow rate is equipped with a three-stage adjustment.

The permissible temperature of the coolant in household products should not exceed + 110 ° C, for industrial products the temperature limit has been increased. As for the working pressure, the units operated in everyday life are able to withstand 10 bar, and industrial ones - 16.

The operation of the system is controlled by automation. Some models of circulators have a thermostat. The functions of the mechanism are displayed on the liquid crystal display. You can also control the shaft speed by manual switching. Connecting the device is simple and quick, which is facilitated by the presence of spring terminals. Power surges are not terrible for the pump, since the motor and rotor have a multi-stage protection system.

1.1 Requirements for operation and prevention

In order to avoid premature repair of Wilo pumps, the manufacturer urges to adhere to the following:

Subject to these rules, the pump will be characterized by maintaining a stable pressure, and the sound emitted during operation will be uniform and quiet. Most pumps do not need to be repaired for 5 years from the moment they are put into operation. It is required only when the main components are completely worn out or force majeure circumstances that caused the device to fail.

Prevention is another type of periodic measures, the implementation of which insures the pump and its elements against premature breakdowns. At the same time, simple maintenance is carried out with his own hands, without the intervention of a specialist. To do this, visual inspection of the external and internal parts of the unit should be carried out at least 3-4 times annually and cleaned if necessary.

Practice shows that cleaning becomes mandatory after 2-3 years of operation. The quality of the coolant, the general conditions under which the heating system operates affects the conduct of cleaning procedures.

For prevention, it is necessary to prepare a Phillips and flat screwdriver, a spanner wrench, and a cleaning brush. Inspection requires disassembly, during which you will find the main components of the hydraulic structure: housing, impeller, motor shaft, rotor, terminal box, propeller and the motor itself. Pay attention to such nuances:

• grounding performance;
• absence of leaks at the joints;
• pressure value in accordance with technical standards;
• lack of vibration and extraneous sounds (knocking, clanging);
• hull condition. It must be clean and dry;
• the pump should not get very hot;
• the amount of grease on bearings, flanges and driving units must be sufficient;

Also make sure that the terminal box cables are free of moisture and securely fastened, the gaskets provide a seal, and the connections to the mains are strong. Before dismantling the device, water is drained from the system, the area of ​​\u200b\u200bits receipt is blocked, after which the pump is removed.

6 bolts connecting the shell of the pump part and the motor housing are unscrewed with a ring wrench. When the shell is removed, access to the drainage holes will appear. The impeller remains on the motor rotor. With the help of a narrow flat-type screwdriver, a shirt is prying off, which serves for the impeller and motor compartment. The actions taken will bring the rotor shaft and the impeller out of the stator cup.

At this stage, the inner surface of the shell, the rotor and the impeller are cleaned of dirt deposits or scale. A stiff polymer brush and a small amount of hydrochloric acid cleaner will help with this. It would be useful to check all seals and gaskets for cracks, if found, replace them with new ones.

Repair of the pump is carried out only after disconnecting the power cable and drainage of the site. It should be said that pumps with a wet rotor are equipped with modules depending on the required power and size. Restoring the health of these devices is facilitated - the faulty module is replaced with a new one.

If the warranty period has expired and the repair is minor, you can do it yourself; in case of a more serious malfunction, take your pump to a service center. Most often, repair work comes down to replacing entire assemblies or the entire pump. The following working parts are subject to replacement: connection block, capacitor, speed controller, bearings.

2.1 Disassembly of Wilo circulation pumps for repair (video)

2.2 The shaft does not rotate when the pump is on and characteristic sounds

The reasons are: oxidation of the shaft after a long period of inactivity or the ingress of a foreign object into the impeller. In the first case, you need to repair the pump by following these steps: drain the water, unscrew the screws that tighten the motor and housing. Remove the motor with rotor and impeller. Turn the last knot by hand. Low power products require a screwdriver to unlock the shaft. For her, there is a special notch at the end of the shaft.

In the second case, it is enough to dismantle the electric motor and remove the foreign object. To eliminate this situation in the future, install a strainer in front of the pump. Also, the reason for the failure of the shaft may be problems with the power supply. Check the voltage in the network for compliance with the passport data of the circulator, pay attention to the presence of phases and the correct connection in the terminal box.

2.3 When the temperature in the system rises above 40 ° C, a creak appears

The reason is that the motor pulley hits the drain plug. Noise is eliminated by putting an additional plastic gasket on the cork; if necessary, the cork thread is turned. If the creak appears again, it is advisable to saw off part of the pulley (with markings for a screwdriver) using a grinder. It should be cut about 3 mm and exactly the area that does not go along the sleeve.

2.4 The unit stalls after a short period of operation

The "root of evil" lies in the scale formed in the immersed part of the rotor. To eliminate the problem, disassemble the drive, then clean the limestone deposits between the rotor and stator with a brush. To prevent the formation of scale on the impeller, pouring the stator cup, install a filter.

2.5 The pump vibrates, accompanied by noise

The reason lies in the wear of the bearings that ensure the rotation of the impeller. Worn parts must be replaced. Since the bearings are pressed into place with a puller, you will need a wooden mallet. Drive new bearings into the seat with precise, but gentle blows. The reason for vibration and loud noise may be low pressure in the system. Elimination implies its increase at the inlet, do not forget that the liquid level in the coolant also needs to be increased.

2.6 Low water pressure in the system

This problem occurs when the phases are incorrectly connected in three-phase pumps or the percentage of fluid viscosity is increased. For the first reason, it is enough to connect the equipment according to the instructions. In the second case, the repair comes down to cleaning the nozzle filter, checking the good condition of the pipeline connected to the pump, and adjusting the installation parameters in accordance with the equipment rating data.
