Vibrating pump kid DIY repair

Considering that submersible vibration pumps are a common technical device, in the course of their operation, malfunctions also often occur, which can lead to a variety of reasons. For example, a breakdown of such equipment can be associated with a malfunction of the power magnet or winding, a break in the traction, a break in a valve, an open circuit or a short circuit. At the same time, these devices often have simple breakdowns, which every owner can cope with.

However, even after carrying out a high-quality repair of the pump, the kid with his own hands, he often fails to return to the previous level of work. Sometimes you can observe a completely sad situation when the device cannot perform its main function. For this reason, great care should be taken when assembling and adjusting the pump. It is possible to carry out these works correctly only if the owner has an idea of ​​the design equipment and the principle of its operation. At the same time, it will be useful to know about the nuances of proper pump settings, which this article is devoted to.

Not every owner knows how to identify the cause of a vibration pump breakdown and return it to working condition with his own hands. This task will be much easier if you learn how this device works, and what nodes does it consist of... First of all, this information will be useful to those who for the first time failed a vibrating pump Brook or Aquarius and who do not understand where to start repairing submersible pumps with their own hands.

The trickle or Aquarius submersible pump performs its main function due to its ability to convert alternating current strength into mechanical vibrations transmitted by the armature and piston. It is these nodes that provide water circulation. When the piston starts to vibrate, water flows under pressure from the hydraulic chamber to the outside, entering the discharge pipe.

The design of the pump can be distinguished the following elements:

By its design, the electromagnet has the form of a core with two coils on which a copper cable is wound. A mandatory operation when placing an electromagnet in the pumping unit body is to apply a compound to this element. This procedure allows you to securely fix the magnetic system in the case, as well as provide good insulation and heat removal.

The following components can be distinguished in the vibrator design:

The rod and the armature form one common connection, where the first is fixed under pressure in the second. As for the shock absorber, it is located on the rod. According to its design, the rod looks like a rubber membrane, which must be made of very high quality, since certain characteristics of the operation of the Trickle, Aquarius pump depend on this.

An important role is played rubber diaphragm, which is secured by an emphasis. This ensures that the hydraulic and electrical chambers of the pump do not come into contact with each other, and in addition, it provides support for the stem, influencing its direction. A rubber piston is always present at the top of the rod.

Another element present in the equipment body is a rubber valve, the task of which is to close off the outlet openings during operation of the installation, however, when no water enters the pump, it allows it to escape.

To cope with a malfunction that has arisen, you should know not only the cause of its occurrence, but also an effective method for its elimination.

Buzzing but not pumping

It is possible to determine what caused this malfunction if we recall the pump device: there are two nuts on the rod directly above the shock absorber. When their attachment begins to loosen, the shock absorber changes its position, which, in turn, brings the vibration pump to idle.

To eliminate this malfunction, the pump is disassembled, after which it is necessary to tighten the nuts as much as possible, and the upper one must be locked. The tightening screws located on the cover can create a serious problem: this will happen if they are covered with rust, which makes it difficult to remove them without special tools. A Bulgarian can help in this matter. When it is time to assemble, you can use hex head tightening screws instead.

Also, the malfunction in question may be associated with damaged valveswho have exhausted their resource. Sand, which often gets inside the pump, can be a contributing factor. For this reason, it is imperative to make sure that the rubber elements are not damaged. If the valve has undergone excessive wear or severe damage, then it will have to be replaced.

Along with this, a similar breakdown can be associated with a stem break. Therefore, it will be useful to make sure that he was not injured either. If you are late with this, then its extraction, even if a slight deformation is obtained, becomes almost impossible.

During pump operation, it is often observed knocking out plugs, charring the cable.

A burned-out armature winding or cable malfunction can be called the cause of such a malfunction. If the first reason takes place, then the repair will not bring the desired result: in addition to the fact that it is possible to rewind the anchor only with certain knowledge, the effect of this operation, which will require a lot of time and effort, will be insignificant, since there is no guarantee that a short circuit will occur again.

In principle, a new winding can be made by rewinding the coils. However, this operation should be performed taking into account such parameters as the thickness and grade of the wire; the number of turns that will have to be created for a specific voltage, and others. However, the simpler solution seems to be precisely the use of a new winding.

To check the cable, a special device is used - a tester. It is not always possible to replace a faulty cable, since in "Little boy" the wire is covered with a compound. Only when the task arose to add lengths to the wire, you can resort to the method of twisting it.

Strong vibration and overheating of the pump

If the pump is overheated, then this may be due to turning it on without water. In such cases, it is highly likely that the device will burn out. Such a phenomenon as overheating leads to the expansion of the case, the compound filling gradually begins to move away from its surface, which covers the magnet from all sides, which usually ends with the appearance of vibration. If the pump runs for a rather long time without water, then the magnet may lose its entire filling. When the magnet and the piston begin to closely adjoin each other, the piston is no longer able to continue its work.

To eliminate this malfunction and to avoid its occurrence in the future, it is very effective to use the following method.

At the first stage the pump is being disassembled, as a result of which it is necessary to remove its electrical part. Next, you need to knock on the case to make sure that the magnet moves freely inside. It must be removed from the case, and why make grooves about 2 millimeters deep on it, using a grinder for this purpose. Moreover, the grooves should run both along and across.

On the inside of the case, they are made without adhering to the principle of symmetry.Then a sealant is applied to the surface of the housing, which can be replaced with glue, after which the magnet is pressed inside the pump. After waiting for the magnet to be fixed with the sealant, you can start assembling the pump.

It should be mentioned that today there are pump models on sale that have suction holes located at the top of the case. Thanks to this design, the problem of lifting impurities from the bottom of the well is effectively solved, as well as cooling the pump, as a result of which the device can operate without any risk and with an empty tank for 7 hours. If a thermal relay is provided in the design of the device, then in this case the pump will automatically turn off during power surges or overheating. However, such models are much more expensive than conventional pumps.

Low pressure, the pump does not pump well

The most common cause of this kind of breakdown is a small gap in the vibrator. If the inspection showed that the valve is not damaged, the fastening of the nuts on the stem is not loosened, and there is no break in the thrust, then to eliminate the malfunction, it is enough to put additional washers on the vibrator. Such a solution will help to increase the clearance, which will lead to an increase in pressure and, consequently, in pump stroke. Keep in mind that when carrying out such an operation, the device should always be set up and checked - the required number of washers can be calculated only based on the results of the pump operation.

Among all the malfunctions that the owners of the "Malysh" and "Aquarius" pumps face, it is often possible to observe the peeling of the epoxy compound from the body. The main reason for this is unbalanced expansion the aluminum housing of the plastic compound at those moments when the elements of the equipment are heated.

1. Before starting repairs, the pump should be removed from the well or well and disconnected from the network.
2. We begin to analyze the equipment. Remember that most often bolts act as fasteners fixing the pump working units.
3. We take a small hammer and apply light blows to the body. Thus, we need to find out where the compound has departed. You can understand this by the presence of a sonorous sound.
4. Find the knot with the compound and pull it out.
5. With the help of a grinder, you need to make notches on the aluminum case from the inside, which should resemble a grid. A similar operation is performed with a unit that has been treated with a compound. It is very important that the depth of the grooves created does not exceed 2 millimeters.
6. Next, you need a sealant, which should be used to cover the inner side of the body and the assembly itself with the compound. The most suitable means for performing such an operation seems to be a composition intended for joining glass surfaces.
7. We take the assembly with the compound and return it to the "Aquarius" pump casing - this can be done only by creating a pressure of about 300 kilograms.
8. When the sealant has set, we begin to assemble the pump in reverse order.

To find the cause of the breakdown and eliminate it, you must correctly assemble the pump, configure and test it. To do everything correctly, you need to be very careful and avoid errors when performing operations. At the initial stage of assembly, make sure that the clearance between the piston and the magnetic system of the pump is sufficient - its thickness should be about 4-5 millimeters.

Next, you need to make sure that the valve is not damaged. To do this, we begin to blow in the direction of the water inlet - all air should freely pass through the valve. The piston should also be inspected, making sure its integrity, elasticity and absence of deformation.

Further it is necessary find out the size of the gap between the body and the valve, which is located close to the suction ports. Ideally, if the gap is 0.6-0.8 millimeters.If everything is in order with the gap, then it will effectively perform its main function - to provide free baking of water when the pump is in the off state.

When assembling the body, you must make sure that the symmetrical elements retain their dimensions. To do this, the hole that ensures the removal of water in the rubber gasket must be aligned with the hole located in the upper part of the case.

Although the Malysh pump seems to be a technically complex device, its can be repaired on their own. The main thing is to know which elements of the pump play a key role in its operation and how to behave in the event of certain malfunctions. Observing the above-described pump assembly technology upon completion of the repair, you can be sure that this equipment will continue to effectively cope with its main task.

Most gardeners and gardeners use a water pump to provide water supply, as well as watering a greenhouse, garden beds, orchard or lawn. Often they buy various models of submersible vibration pumps and the absolute priority is "Kid". They are small in size, inexpensive, but have good power, allowing you to supply water over a long distance.

But these budget electrical appliances have a significant drawback - they often fail for various reasons. With some breakdowns, it is quite possible to repair the pump with your own hands. About what breakdowns are most common and how to repair - our article.

It is possible to carry out a high-quality repair of a vibration pump with your own hands only if you understand its structure, as well as the principle of operation. Information about setting up an electric pump will not be superfluous. Indeed, there are situations when the repair work was carried out correctly, but due to the fact that there was no competent setting, the unit cannot perform its function.

The design consists of the following basic elements:

• metal case;
• electromagnet;
• vibrator.

The baby vibration pump device has a standard look for such technical mechanisms.

The water pump can be with top or bottom water intake. If vibration pumps have an upper liquid intake, then the suction valve is at the top, and the electric drive is at the bottom. This arrangement has several advantages:

• The "electrical part" of the device is under water, which contributes to constant cooling;
• silt deposits from the bottom are not absorbed.

Models with a lower water intake have the opposite arrangement of the mechanism components. Such units require constant monitoring of the water level. Dry running leads to overheating and, as a result, to breakdown. The technical parameters of the models differ from each other.

In order to know how to repair a pump, a baby needs to learn all the nuances of installing the mechanism. It is important to know not only the device of this device, but also all its "problem areas".

The electromagnet is firmly fixed in the housing with a compound. It not only fixes the core with the coils, but also acts as an insulator and transfers heat from the coils to the body. A compound is a special mixture that is prepared from epoxy resin, sand, and also a plasticizer. Carrying out repairs with your own hands, the damaged areas of the compound are sealed with a sealant.

Vulnerable elements of a submersible electric pump are rubber parts. Despite the fact that they are made of high quality material, they wear out during operation, and therefore require replacement. If the pump is out of order, the repair should begin with the inspection of the rubber parts.

Please note that there must be a gap of 0.6-0.8 mm between the body and the valve. It allows water to flow out when there is no pressure.

First of all, you should inspect the rubber valve covering the inlet. It has to be changed more often.After that, we inspect the rubber diaphragm that separates the hydraulic chamber from the electric drive. Don't ignore the rubber piston located on the rod.

The principle of operation of a vibration pump is that the alternating current is converted into electromagnetic oscillations of the armature, which are transmitted to the piston located on the same rod. The oscillating motion of the piston builds up pressure, allowing water to be pumped.

Schematic representation of the device

How does an electric pump work? After connecting the device to the mains, the magnet attracts the armature. At this moment, the poles are magnetized. The shock absorber performs its function - to return the anchor to its place. This process takes place in half the period of the current wave. Accordingly, over the full period, the anchor will be pulled twice. Considering that the frequency of the mains is 50 Hz, then there will be 100 armature oscillations per second.

The rubber piston vibrates with the same frequency. After all, it is located on a rod pressed into the anchor. The pump device contributes to the formation of a hydraulic chamber, which on one side is limited by a valve near the inlet, and on the other by a piston.

Water is an elastic two-component medium consisting of air that has dissolved and that which has not dissolved. Through the inlet, the valve passes liquid into the inside of the electric pump. The vibration of the piston causes the water to behave like a spring. Each time you unclench, some of the water is pushed out of the appliance chamber.

Having mastered the device of the baby vibration pump, you can start repairing it. We bring to your attention examples of how to repair a baby pump on your own.

Assembling the Kid with your own hands

1. The main and most important thing before disassembly is to mark the location of the parts relative to each other on the case. It is best to cut with a sharp screwdriver. But you can do it with a marker.
2. Next, remove the screws that connect the pump. First, in turn, unscrew the screws a few turns, and then completely twist them. For convenience, the device can be fixed in a vice.
3. The piston disc is set parallel to the saddle along the axes, checking the distance from the edge to the gasket with a centimeter or compass. Sometimes the parallel is broken. The reason may be a grover on the screw (you can wrap a strip of foil under it) or a bend in the stem (turn the gasket slightly to align it).
4. It is important during assembly not to confuse the position of the rubber gasket where the holes match.
5. After correcting the deficiencies or breakdown, you need to check the operation of the pump. To do this, it is dipped in a bucket full of water. Even if there is no hose, if the equipment is working properly, a stream of water will flow from the branch pipe.
