Among the owners of private houses and summer residents, pumping manual devices that work on the vibration principle are quite common. One of the most common models is the "Kid" pump. It has a low cost, but its performance is quite high.
Needs to repair
The equipment pumps water over impressive distances. Like any other technical equipment, the described requires regular maintenance. Owners of such units can carry out repairs on their own. If you have the most minimal technical skills, then you can do the work at home.
How to disassemble the device and reassemble it for repair
Repair of vibration pumps "Kid" involves disassembling the device. Before that, notches must be made on the case to indicate the location of the parts of the device. The screws that serve to connect the body parts must be removed one by one. Each of them is loosened by a few turns. In order to easedismantling of a part of the body under the fixing screws, in the area of the ledges it is necessary to carry out compression with a vice. To simplify subsequent maintenance manipulations, conventional screws are replaced with similar ones. An alternative solution is bolts that have perpendicular slots on their heads. A piston disc is installed parallel to its seat, while maintaining the alignment of these nodes.
You can check the parallelism by measuring with a caliper, checking the distance from the gasket to the edge of the piston. If you do not observe parallelism, then you can call the grower on the nut. For the correct position of the grower, a piece of foil is wrapped under it. If there was a violation of parallelism, then a bend in the stem could lead to this. You can eliminate its inclination by unfolding the gasket.
When assembling the pumping device, it is important to consider that the holes in the gasket match. They should be centered and located at the top of the case. Their mutual position can be easily confused, because the nodes are symmetrical. You can check if the unit is working by lowering it into a liquid. When there is no hose, a jet of liquid will come out of the outlet nozzle, the height of which reaches 30 cm.
Pouring the compound
Repair of the "Kid" submersible pump may be required when the epoxy compound peels off from the casing. This can be caused by uneven expansion of the aluminum structure and the plastic compound at the time of temperature increase. In order to carry out the replacement, it is necessary to lift the pump fromwells and wells and de-energize it.
The device is disassembled. Usually its components are fixed with bolts. It is necessary to tap the body with a hammer and understand where the places of delamination are, you can recognize them by the characteristic ringing. At the next stage, the assembly with the compound is removed from the body. Notches are applied to the inner surface of the housing using an angle grinder, which should look like a grid. The same notches should be located on the node with the compound. Grooves must be made taking into account the depth within 2 mm.
When the “Kid” water pump is being repaired, at the next stage a sealant is applied to the inner surface of the housing, this also applies to the assembly with the compound. It is recommended to prefer a composition that is designed to connect glass surfaces. The assembly with the compound is placed inside the case, and a fairly impressive effort must be applied. Once the sealant has cured, the pump can be reassembled in reverse order.
How to check if the pump parts are in the correct position
Repair of the "Kid" pump during disassembly may be accompanied by an audit, which allows you to understand whether the components of the device are located correctly. The gap between the solenoid coils and the piston should be approximately 5 mm. It is important to check the condition of the valve. It must be blown in both directions.
The valve must show no visible damage. For reliable fastening of the valve, its nut must be supplemented with one more. It is important to make sure that there is no mechanical damage on the piston assembly. Despite the fact that it is firmly reinforced, it must retain a certain flexibility. For its reliable fixation on the sleeve assembly, it is necessary to rivet the nut. To increase reliability, you can counter it.
Work methodology
Repair of the "Kid" pump may also be accompanied by disassembly of the sleeve block. The piston assembly is removed for this, as is the washer, which is responsible for adjusting the distance between the membrane and the sleeve. There may be several of these washers. The stop ring is removed, and from the side of the piston assembly it is necessary to remove the membrane, which is made of durable rubber. This will allow you to see the aluminum cylinder.
The sleeve assembly is pressed against the spring, the cylinder can be dismantled. When reassembly is carried out, the gap can be adjusted. Do-it-yourself repair of the “Kid” pump is carried out in such a way that the created distance is 0.5 cm. You can change this value by adding or removing washers that are installed on both sides.
The hose is detached from the equipment and hung out in a bucket that is pre-filled with water. As soon as the power is turned on, you need to check the mains voltage so that it is between 220 and 240 volts.
Final works
When do-it-yourself water pump "Kid" is being repaired, at the last stageit is necessary to turn off the device and drain the water from the equipment. It is important to make sure that the valve is open. It must be blown through, the air must pass freely, and as the pressure increases, you will feel the hole blocking. The piston assembly must move. When blowing in the opposite direction, the air flow should again pass without visible obstructions.
Pump setting
If the equipment cannot be blown directly, then the defect can be corrected by reducing the operating voltage to 200 volts. You can do this with a transformer. Sometimes the owners of the described equipment are faced with the fact that the pump does not pump water. The locknut in the adjusting screw sometimes loosens. The screw must be turned, which will affect the efficiency of the unit.
The cause is sometimes also a pumping cuff made of rubber, which can be damaged. You can see this malfunction only if you disassemble the pump. This knot outwardly looks like a pair of saucers, which are arranged to each other with bottoms. Their diameter is approximately 4 cm. You can buy such cuffs for a penny, and they are sold in specialized departments.
Do-it-yourself repair of the “Kid” pump may also be required if the pumping rod fails. This error is quite serious. It will be extremely difficult to work without special equipment. Such a breakdown can be repaired if you have another pump that will play the roledonor.
Main malfunctions
Repair of the "Kid" pump may be required if the equipment has been running dry for a long time. In this case, overheating occurs. The design provides for the presence of a stator, which at idle can face serious damage. Damage can accumulate. The service life decreases over time, and then reaches a critical level. Then there is a short circuit of the turns.
A breakdown of this kind can be eliminated by rewinding the coils of the unit. Repair of the "Kid" pump is sometimes required even when the connections in the housing are loose. This happens with constant use. Threaded connections can lose strength due to vibrations. If the threads have been loosened on the piston as well as the valve, then it will not be possible to see this with a simple inspection of the body. The problem can be solved only by the method of periodic prevention. All connections are regularly inspected by the master and well tightened.
The most common breakdowns and how to fix them
If you can’t deal with problems on your own, then the Malysh pump is being repaired in Moscow today. For example, you can contact RemBytTekhnika, which is located 8 km from the Moscow Ring Road. If you plan to carry out the work yourself, then first you need to deal with the cause of the breakdown.
Sometimes it also happens that the check valve with the piston has received increased wear. To prevent this problem, it is importanttake care of sealing the case, because the manufacturer installs rubber gaskets that cannot be sufficiently effective. Water with coarse mechanical impurities passes through them, which affects the working condition of the piston.
It is important to use a mechanical type filter, this will minimize the effect of the contaminated environment on the equipment. If you have such devices, then you may encounter problems with the check valve in the unit. In order to eliminate the problem, when preparing the device for operation, it is necessary to adjust it. To check, use a barrel of water or other capacious container. It is important to achieve maximum pressure by changing the tension of the nut on the valve.
Conclusion
If you plan to repair the pump yourself, then you need to start such work with the dismantling of the equipment. This stage is perhaps one of the most difficult. The body of the equipment is two halves, which are pulled together by four bolts, so you may encounter certain difficulties during disassembly.
