How to repair a dzhileks drainage pump. Repair of the submersible borehole pump "Vodomet": fixing breakdowns with your own hands

Well pumps are used all over the world. After their invention and appearance on the mass market, the popularity of this equipment began to grow.

However, pumps tend to break down, and it will be necessary to fix the breakdown as soon as possible. You don't want to live weeks without water. It is about the repair of the pump that we will now talk about, and for the closest example we will take products from the company.

1 The main breakdowns of pumps and their diagnostics

The pump is a fairly simple mechanism. Its design is not particularly complex, but this is only a comparative judgment. After all, it has an engine, contacts, an impeller, a shaft, seals, a housing, etc.

All these parts interact with each other, which leads to their gradual wear. As a result, the pump will need to be repaired.

Plus, it is worth noting that the pump works in rather difficult conditions. This does not apply to Gilex surface pumps, which are assembled with and installed in separate rooms. However, even such equipment often needs repair.

2 How is the Gilex pump repaired?

Now consider directly the repair of pumping equipment. It should be understood that the repair of a submersible sample will be different from the repair of a surface one.

To begin with, let's turn to models of the Water Cannon type. The Waterjet pump is a submersible pump that is available in various configurations. There are models of the 40/50, 55/35, 110/110 line, etc. However, they differ not so much in design as in the choice of specific components and dimensions. Otherwise, their design is extremely simple and repeats constantly.

Repair of the Water Jet pump always begins with its disassembly. To do this, it must be carefully removed from the well, disconnected from the system and dry the pump from the water.

Stages of work:

Remove and dry the device.
Remove the top case or cover.
We remove the water intake mechanisms, you will have to use a vice. But remember that the case is hollow inside, and therefore it is important not to overdo it.
We disassemble the pumping part, if the breakdown lies there, then at this stage you will eliminate it. Otherwise, you will have to move to the engine.
We remove the corkscrew plastic ring and take out the engine.
Carefully pull out the wires and evaluate their condition.
After the repair is completed, fill the engine with non-toxic oil and assemble the pump in the reverse order.

It is important to note that the oil in the engine must be harmless. Glycerin is ideal, as it does not harm or pollute the surrounding fluid.

After disassembling the pump, fixing the problem will be quite easy. Problem contacts can be wiped with alcohol or soldered. Broken wires are replaced with new ones or fastened in an artisanal way.

Damaged consumables or rotating parts are only exchanged. They are cheaper to buy than repair. Well, it’s better to send the engine to a specialist who can disassemble, clean and repair it, and also guarantee you a positive result.

As you can see, disassembling and repairing the Water Cannon pump is quite easy. Moreover, it does not matter which Water Cannon you have chosen, since the design principle remains the same.

They act a little differently when repairing surface pumps and Gilex Jumbo-type stations. Here you need to deal with a specific solution to the problem. If the pump is acting up, then you need to remove the housing and check all systems.

Stages of work:

We disconnect the equipment from electricity, the hydraulic accumulator and drain the liquid in the hose.
Unscrew the back of the case.
We remove the moving parts of the body.
We disassemble the pump chamber.
We remove the impeller seals.
Carefully pull out the engine.
We deal with wires.
After the repair is completed, we assemble the pump back.

As in the previous case, you can solve the problem with a breakdown at any stage. The advantage of surface pumps is that their body is not one-piece, and it is easier to remove it. In this case, the parts can be inconsistently removed and turned off.

If there are problems with the impeller or consumables, then they are simply changed. You will have to get to the contacts through the engine camera - this is the main problem, but there should not be anything complicated here either.

Hydraulic accumulators are disassembled by disconnecting the hose and unscrewing the plate. Then the membrane is pulled out from there. It is advisable not to repair the relay yourself, as it is very easy to damage it.

2.1 Overview of the design and properties of the pumps of the Vodomet line (video)

It is usually created using a pumping station. It is clear that it is better if it works without problems, but breakdowns happen from time to time. To quickly restore the water supply and save on services, you can repair the pumping station with your own hands. Most of the breakdowns can be fixed on their own - you don’t have to do anything super complicated.

The composition of the pumping station and the purpose of the parts

A pumping station is a collection of separate devices interconnected. To understand how to repair a pumping station, you need to know what it consists of, how each of the parts works. Then troubleshooting is easier. The composition of the pumping station:

Each of the parts is responsible for a certain parameter, but one type of malfunction can be caused by the failure of various devices.

The principle of operation of the pumping station

Now let's look at how all these devices work. When the system is first started, the pump pumps water into the accumulator until the pressure in it (and in the system) equals the upper threshold set on the pressure switch. While there is no water flow, the pressure is stable, the pump is off.

A faucet was opened somewhere, the water was drained, etc. For a while, water comes from the accumulator. When its quantity decreases so much that the pressure in the accumulator drops below the threshold, the pressure switch is activated and turns on the pump, which pumps water again. It turns off again, the pressure switch, when the upper threshold is reached - the shutdown threshold.

If there is a constant flow of water (a bath is taken, watering the garden / vegetable garden is turned on), the pump works for a long time: until the required pressure is created in the accumulator. This happens periodically even when all taps are open, since the pump supplies less water than flows out of all points of analysis. After the flow has stopped, the station works for some time, creating the required reserve in the gyroaccumulator, then it turns off and on after the water flow appears again.

Problems and malfunctions of pumping stations and their correction

All pumping stations consist of the same parts and their breakdowns are mostly typical. It makes no difference whether the equipment is Grundfos, Jumbo, Alco or any other company. Diseases and their treatment are the same. The difference is how often these malfunctions occur, but their list and causes are usually identical.

The pumping station does not turn off (does not gain pressure)

Sometimes you notice that the pump has been running for a long time and will not turn off in any way. If you look at the pressure gauge, you can see that the pumping station is not gaining pressure. In this case, the repair of the pumping station is a lengthy business - you will have to sort out a large number of reasons:

If the shutdown limit of the pressure switch is much lower than the maximum pressure that the pump can create, and for some time it worked normally, but then it stopped, the reason is different. Possibly the pump the impeller worked. Immediately after the purchase, he coped, but during the operation the impeller was worn out and "now there is not enough strength." Repair of the pumping station in this case is the replacement of the pump impeller or the purchase of a new unit.

Another possible reason is low voltage in the network. Maybe the pump is still working at this voltage, but the pressure switch is no longer working. The solution is a voltage stabilizer. These are the main reasons that the pumping station does not turn off and does not build up pressure. There are quite a few of them, so the repair of the pumping station may be delayed.

Repair of the pumping station: often included

Frequent switching on of the pump and short periods of its operation lead to rapid wear of the equipment, which is very undesirable. Therefore, the repair of the pumping station should be carried out immediately after the discovery of the "symptom". This situation occurs for the following reasons:

Now you know why the pumping station often turns on and what to do about it. By the way, there is another possible reason - pipeline leakage or some connection, so if all of the above does not apply to your case, check if the joint is leaking somewhere.

Air in water

There is always a small amount of air in the water, but when the faucet starts to “spit”, something is not working properly. There can also be several reasons:

The pump station does not turn on

The first thing to check is voltage. Pumps are very demanding on voltage, they simply do not work at low voltage. If everything is fine with the voltage, things are worse - most likely the motor is faulty. In this case, the station is carried to a service center or a new pump is installed.

If the system does not work, you need to check the electrical part

Other reasons include a plug / socket malfunction, a frayed cord, burnt / oxidized contacts at the point where the electrical cable is attached to the motor. This is something you can check and fix yourself. A more serious repair of the electrical part of the pumping station is carried out by specialists.

The motor hums but does not pump water (the impeller does not rotate)

This error may be caused low voltage in the network. Check it, if everything is normal, move on. You need to check if it's burned out. capacitor in terminal block. We take, check, change if necessary. If this is not the reason, go to the mechanical part.

First you should check if there is water in the well or well. Next, check the filter and check valve. Maybe they are clogged or defective. Clean, check the performance, lower the pipeline into place, start the pumping station again.

We check the impeller - this is already a serious repair of the pumping station

If that doesn't help, the impeller may be jammed. Then try manually turning the shaft. Sometimes, after a long period of inactivity, it "sticks" - it becomes overgrown with salts and cannot move itself. If you cannot move the blades by hand, the impeller may have jammed. Then we continue the repair of the pumping station by removing the protective cover and unlocking the impeller.

Some types of repair work

Some do-it-yourself pumping station repair steps are intuitive. For example, it is not difficult to clean a check valve or filter, but it can be difficult to replace a membrane or a pear in a hydraulic accumulator without preparation.

Replacing the "pear" of the accumulator

The first sign that the membrane is damaged is the frequent and short-term switching on of the pumping station, and the water is supplied in fits and starts: sometimes strong pressure, sometimes weak. To make sure that the diaphragm is the problem, remove the plug on the nipple. If not air comes out of it, but water, then the membrane has torn.

To start the repair, disconnect the system from the power supply, relieve pressure - open the taps and wait for the water to drain. After that, it can be turned off.

Loosen the flange at the bottom of the tank. We are waiting for the water to drain.
We unscrew all the bolts, remove the flange.
If the tank is from 100 liters or more, unscrew the membrane holder nut at the top of the tank.
We take out the membrane through the hole in the bottom of the container.
We wash the tank - it usually has a lot of rusty sediment.
The new membrane must be exactly the same as the damaged one. We insert a fitting into it, with which the upper part is attached to the body (we twist it).
We install the membrane in the accumulator tank.
If there is, install the membrane holder nut at the top. With a large tank size, you can’t reach it with your hand. You can tie the holder to the rope and so install the part in place by screwing the nut.
We tighten the neck and press it with a flange, install the bolts, successively twisting them several turns.
We connect to the system and check the work.

Replacement of the pumping station membrane is completed. It's a simple matter, but you need to know the nuances.

Dzhileks pumps are pressure equipment for water supply, which has come into our everyday life since 1993, when the Dzhileks plant was founded in the Russian city of Klimovsk, Moscow Region.

Pressure equipment for wells and wells, for use in open reservoirs and sewers, intelligent water supply systems and hydraulic accumulators, expansion tanks, pipes and fittings - the plant's product line is expanding and improving with each.

Features of the repair of Gileks pumps

Despite the fact that Gileks products are durable and durable, like any other equipment, it requires periodic inspection, prevention or repair. Fortunately, the range of accessories and additional equipment allows you to solve the problem of any level of complexity. And a wide dealer network and a well-functioning system of service centers can always help in repairs.

But, given the specifics of the mentality of our people and, sometimes, the real lack of the ability to take the device to the service center, you can always fix the Gileks pressure equipment with your own hands. However, to begin with, let's look at what and why can fail in pressure vessels.

Problem Diagnosis

Any pressure equipment gradually wears out, and, due to a number of reasons, it can periodically cause some inconvenience to its owners that require urgent intervention. Fortunately, the design of the pumps is quite simple:

case box;
electric motor;
sealing system;
shaft with impeller;
pipe branch;
flow channel and check valve;
filters;
electric cable.

The most common problems that users of pressure equipment may face can be:

when connected to the network, the equipment does not turn on - you need to test the contacts, drive and cable;
increased noise or vibration during operation of the equipment - check the motor, shaft bearings and impeller;
the motor does not respond - it is necessary (if possible in a particular model) to check and replace the winding;
the relay or hydraulic accumulator fails - most likely the reason is a rupture of the membrane or a level of water pressure in the system that is different from that stated in the technical data sheet of the product;
the pump does not turn off - most likely the problem is a malfunction.

Do-it-yourself pump repair Dzhileks Vodomet

Consider the most common models of water jet pressure equipment, which have a similar apparatus structure. This is a range of submersible pumps marked Profi - improved specifically for working in wells with sandy walls and bottom.

Models 40/50 (75), 55/35 (50/75/90), 110/110 (75H/110H) practically do not fail from overheating, because equipped with an annular gap for cooling the engine with water. In addition, the valve and piston system is eliminated from their design, which contributes to greater durability and added filter system, which does not often clog the inlets. And two seals for insulating and sealing the electric motor and a remote thermal switch greatly facilitate the diagnostic process and.

Systems of old models Vodomet 60/52 (32/72/92) and 115/75 (115) designed for static water levels from 5 to 25 meters. The main difference between the models is the different number of steps.

Repair of the submersible pump Gileks Vodomet 60/52 must begin with a careful disassembly of the apparatus, after an external examination and diagnostics. If you are disassembling the device for the first time, then it is important that the diagram and order of the parts to be disassembled during subsequent assembly are strictly observed.

Following the instructions of the Gileks company, the repair of the Water Jet pump begins with unscrewing the water intake hole. Then we remove all the parts from the shaft, and only then we take out the white stopper ring and the engine from the outer glass. The procedure is as follows:

install the device in a vertical position;
tapping on the fitting cover, move the ring with the engine, which cannot be pulled out simply through the thread;
set the device in a horizontal position and, pulling the cable back a little, move the engine back;
rest a screwdriver on the ring and slide it so that it can be deployed across the body;
take out the ring and the engine;
we disassemble the wiring compartment and check the capacitor compartment for moisture ingress (especially if the device was energized);
check ;
we check the covers between the steps and the impellers for the degree of wear (we pay special attention to these details if the device was buzzing, but did not pump water);
check the filter grids.

Repair of drainage devices Gileks

Drainage devices are specially designed in such a way as to pump liquids of varying degrees of contamination from the desired space. All models of this kind are equipped with protective floats to prevent dry running and sealed bearings. Otherwise, modifications differ from model to model in details.

You can repair a faulty Gilex if two problems are observed:

the device does not turn on;
The device is buzzing, but refuses to work.

In the first case, you should pay attention to the possibility of failure of the capacitor or the winding. Shutdown of the device can be caused by a short circuit due to voltage drops and a burnt winding. In addition, the pressure unit may turn off if the float is stuck or stuck.

In the second case, either the connection does not work (the cable is frayed outside or inside), or there are problems with the valve or stem. The rod broke or the fasteners on the shock absorber were loose. A broken stem cannot be repaired by itself.

Repair of the pumping station Dzhileks

The pumping station is a self-priming surface centrifugal and piping system. Models of this series are designed for horizontal installation and pump from 3 cubic meters of water per hour. Models differ in the level of engine noise and the presence of automation, which is needed to monitor the water level.

The Gilex unit must be configured to turn off if the water level drops below the declared minimum according to the technical data sheet. If the setting and adjustment of the station is incorrect, it will not turn off in time, which will lead to breakdowns.

Let's consider an example of repairing a pumping station Gileks. They are equipped with a pressure switch RDM 5, a tank with membranes (hydraulic accumulator), an electric motor, a centrifugal pumping apparatus, a water intake with a filter and a piping system. You can monitor the pressure inside the installation using the arrow on the pressure gauge.

There are five main reasons why a station may fail or not work correctly:

It hums but doesn't work. This happens if you left your device for a long time without water and movement. The impeller could just stick to the body. Twist it by hand and try to connect. If it still does not work, check the voltage level of the mains and the condition of the capacitor.
Doesn't turn on at all. Ring the network, winding, cable with a tester. Perhaps somewhere the contacts just went away, and as soon as they are connected, everything will work again.
Pumps water constantly and does not turn off. You need to set up the relay. You can adjust it with two mounting springs or screws (depending on which relay is installed in your station model).
The flow of water is intermittent. The problem is the depressurization of the pipeline or joints. Also, check the water level.
Too frequent switching on of the device with uneven water flow. It is also necessary to check the integrity of the constituent parts of the accumulator tank. Either you have to change the unusable membrane, or the tank is cracked, or the relay itself is broken.

A drainage pump in a suburban area is a kind of lifesaver in case of unforeseen situations. By design, it resembles equipment for supplying drinking water, but it has the ability to move contaminated media with large inclusions.

But like any other technique, equipment can fail. Let's try to understand the weaknesses of the unit and find out if it is possible to repair the drainage pump with our own hands if necessary.

The ability to pump water with fine gravel, large inclusions of sand, organic residues is a very useful quality when you need to pump out water after flooding or drain a pond. Drainage units are designed to work in such conditions, but exceeding the load often leads to breakdowns.

It is better to get acquainted with the internal content of the device immediately after purchase in order to imagine what parts can fail in the event of clogging or breakage. To do this, it is not necessary to open the case or disassemble it - just study the diagram that is attached to the instructions for connecting and servicing the device.

The suction port of the pump unit can have a different location: for submersible models, it is located at the bottom and is equipped with a filter mesh

Devices for private use in summer cottages do not differ in high power or complex filling. Unlike heavy industrial equipment, they are compact, relatively light (average weight - 3-7 kg), consist of steel or plastic parts, although cast iron is still used for the production of industrial models and some household ones.

The main components of the submersible mechanism are a pumping unit that pumps water and an electric motor that rotates a shaft with blades. The motor is housed inside a robust case, which is made of stainless steel or reinforced polypropylene and is double. Water circulates between the outer and inner walls, preventing cooling.

Timely repair of the Gilex pump with your own hands is a guarantee of a long service life in good condition. Most often, malfunctions of devices are depressurization of the housing of submersible units, burnout of the motor winding and destruction of the blades of the impellers, if too large elements get on them.
The article proposes to get acquainted with the features of the pumps of the company "Dzhileks", describes a brief instruction for the repair and operation of the equipment.

What are the features of Jilex borehole pumps

The Water Jet pump, a general view of which is shown in the photo, is a fairly popular model in the budget category. Its price is affordable for many owners of their plots, you can buy a device in almost any plumbing store. Has a large number of positive reviews.

Some features of the unit are as follows:

Compared to other similar devices, Gileks water jet pumps are more responsive to the purity of the pumped water. If there is sand in the liquid, the pump will not last long.
Not the best way to affect the durability of his work: high iron content and lime impurities in the water.
The water cannon necessarily requires the installation of electrical protective equipment:

voltage stabilizer;
machine corresponding to the rated power of the pump.

It is advisable to purchase a device for protection against "dry running".
Do not use Gileks pumps with a capacity of 3.6 cu. m / h in weak wells, with a flow rate of 0.5 to 1 cubic meters. m/hour.

Tip: When purchasing a pump from Gileks, it is necessary to mount it in a well with clean water only, there should be no voltage drops in the power supply, use a stabilizer and all kinds of protection. The parameters of the pump and well must match.

Pump breakdown diagnostics

Like any equipment, Gilex pumps break down, and they need to be fixed as soon as possible so as not to be left without water, especially in the summer. The pump is a fairly simple mechanism that is not very complex.
Its design includes:

Engine.
Frame.
Contacts.
Shaft seal.
Impeller and other elements.

When interacting with each other, they gradually wear out, which may require their repair.
Surface pumps Gileks are assembled with hydraulic accumulators and installed in a separate room, which contributes to their greater safety, in contrast to the submersible pumps of the Gileks-Vodomet line, which are constantly in the water and removed for the winter, which subsequently complicates their use.

Tip: The relative simplicity of the design allows you to repair the units yourself. The main thing is not to make mistakes that can increase material costs.

Diagnosing the most common breakdowns is quite easy:

If the pump does not respond when the electricity is connected, it is necessary to check the contacts and the supply wire. In this case, the device is disassembled and the contacts are diagnosed by the tester. If one of them does not have a signal, then it is damaged.
The unnatural color of the element or it is damp can also indicate its unsuitability. If the reaction is positive, you need to look for the cause in the cable, it may be interrupted. This is more often the case with submersible pumps, where the cable is suspended and poorly protected.
Uneven operation, clicks, “flooding” of the unit indicate problems with the impeller or even with the motor. In this case, you need to disassemble the pump and carefully inspect all the elements. Perhaps the impeller got cracked, or the bearings failed.
If the engine fails, the problem must be sought in it.

Tip: The Gilex pump motor is a rather delicate mechanism, especially for submersible models. If its winding is burned out, then replacing it is not so easy. Therefore, it is better to use a new motor, which Gileks supplies as spare parts for its products.

Due to the occurrence of a “dry run”, it can wear out very much and even burn out at Gileks-Jumbo stations.
Very often in such models there are malfunctions associated with pressure in the system. In this case, the reasons may be:

malfunctions in the pressure switch. Checking and setting it up is quite simple;
hydroaccumulator problems. Here the membrane with air can break or get other damage. In this case, partial disassembly of the tank is necessary. The lack of air in the membrane leads to an imbalance in the entire system, and hence to a drop in pressure.
the pump broke, which happens quite rarely. Usually, working elements fail and the device cannot cope with pumping, which is accompanied by a slight hum, low pressure, and poor rotation of the impeller.

How to repair submersible models of Gileks pumps

Repair of surface pumps and submersible pumps is different.
The submersible device repair sequence is as follows:

The unit is pulled out and dried.
The top case or cover is removed.
The water intake mechanisms are removed, for which it is better to use a vice. But when working, you must be careful, the body is hollow inside, which makes it weak.
The pump section is dismantled. If a breakdown is detected at this stage, it can be fixed, otherwise you will have to move to the engine.
The corkscrew plastic ring is removed and the motor is pulled out.
The wires are carefully pulled out and their condition is assessed.
At the end of the repair, non-toxic oil is poured into the engine and the pump is assembled in the reverse order.

Tip: The oil in the engine must be harmless. Glycerin, which does not pollute the surrounding liquid, is best suited for this.

When disassembling the pump, problems are fixed quite easily:

Wipe with alcohol or solder problem contacts.
Broken wires are replaced with new ones.
Damaged consumables or rotating parts should only be replaced. They cost more to repair than they cost.
Engine repairs are best left to a specialist who will disassemble, clean and repair it. In addition, it will give a guarantee for a certain period.

How are Gileks surface pumps repaired

If there are signs of pump breakdowns, it is necessary to remove its casing and check all systems.
The order of work is as follows:

The equipment is disconnected from electricity, the accumulator and the liquid is drained in the hose.
The back of the case is unscrewed.
The moving parts are removed.
The pump chamber is disassembled.
The impeller, seals are removed.
The engine is carefully pulled out.
wires are controlled.
After completing the repair of the pump, it is assembled in the reverse order.

You can repair this type of device at any stage. Their body is one-piece, which facilitates the removal of the pump, and the parts do not have to be removed and disconnected sequentially. If there are problems with the impeller or consumables, they simply need to be replaced. Contacts can be accessed through the engine's camera, which is a major issue, but it's not difficult.
The hydraulic accumulator is disassembled by disconnecting the hose and unscrewing the plate. After that, the membrane is pulled out. It is not advisable to make the relay yourself, it is easy to damage it.
How any Gilex pump is repaired is well shown in the video in this article. Timely repair of any equipment is the key to its long operation in good condition.
