Among the owners of private houses and summer residents are quite common pumping hand devices that work on the vibration principle. One of the common models is the “Kid” pump. It has a low cost, but its performance is quite high.
Need repair
Equipment pumps water over impressive distances. Like any other technical equipment described, it 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 perform the work in the domestic environment.
How to disassemble the device and assemble it during repair
Repair of vibration pumps "Kid" involves disassembling the device. Before this, notches must be made on the case to indicate the location of the parts of the device. The screws that are used to connect the housing parts must be removed in sequence. Each of them is weakened by several revolutions. In order to facilitate the dismantling of the housing part under the fixing screws, it is necessary to compress with a vise in the area of the ledges. To simplify subsequent maintenance operations, the conventional screws are changed to similar ones. An alternative solution is bolts that have perpendicular slots on their heads. Parallel to its saddle, a piston disk is installed, while alignment of these nodes should be observed.
You can check the parallelism by measuring with a caliper, checking the distance from the gasket to the piston edge. If you do not observe the parallelism, then you can call the grover on the nut. For the correct position of the grover, a piece of foil is wound under it. If there was a violation of parallelism, then this could lead to a bend of the rod. You can exclude its tilt by unrolling the gasket.
When assembling the pumping device, it is important to ensure that the holes in the gasket match. They should be centered and located at the top of the enclosure. Their relative position can be easily confused, because the nodes are symmetrical. Check if the unit is working by lowering it into the liquid. When there is no hose, a stream of liquid will come out of the outlet pipe, the height of which reaches 30 cm.
Compound Fill
Repair of the “Baby” submersible pump may be required when the epoxy compound is detached from the housing. The uneven expansion of the aluminum structure and the plastic compound at the time the temperature rises can lead to this. In order to carry out the replacement, it is necessary to lift the pump from the well and the well and disconnect it from power.
The device is disassembled. Usually its components are fixed with bolts. With a hammer, you need to tap the case and understand where the exfoliation places are, you can recognize them by a characteristic ring. At the next stage, the assembly with the compound is removed from the housing. On the inner surface of the body using an angle grinder, notches are applied, which should be in the form of a mesh. The same notches should be located on the site with the compound. Grooves must be made taking into account the depth within 2 mm.
When the “Kid” water pump is being repaired, a sealant is applied to the inner surface of the casing at the next stage, 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 housing, and a rather impressive effort must be applied. Once the sealant hardens, the pump can be assembled in the reverse order.
How to check if pump parts are in the correct position
Repair of the “Kid” pump during disassembly can be accompanied by an audit, which allows you to understand whether the components of the device are located correctly. The gap between the electromagnetic coils and the piston should be approximately 5 mm. It is important to check the condition of the valve. Its blowing should be carried out in both directions.
There should be no visible damage to the valve. 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 fortified, it must retain some flexibility. For its reliable fixation on the sleeve assembly, it is necessary to unfasten the nut. To increase reliability, you can lock it.
Methodology
Repair of the pump "Kid" may also be accompanied by disassembly of the sleeve unit. For this, the piston assembly is removed, as well as 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 on the piston unit side, 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, while the cylinder can be dismantled. When reassembling, the clearance can be adjusted. Do-it-yourself repair of the Kid pump is done in such a way that the distance created is 0.5 cm. You can change this value by adding or removing washers that are installed on both sides.
The hose is disconnected from the equipment and hung out in a bucket that is pre-filled with water. As soon as the power is turned on, it is necessary to check the mains voltage so that it is in the range from 220 to 240 volts.
Final work
When repairing the water pump "Kid" with your own hands, at the last stage you need to turn off the device and drain the water from the equipment. It is important to verify that the valve is passable. It must be purged, the air must pass freely, and when the pressure increases, you will feel the locking of the hole. The piston assembly must be moved. When blowing in the opposite direction, the air flow must again pass without visible obstacles.
Pump setting
If the equipment cannot be blown directly, then the defect can be corrected by reducing the operating voltage to 200 volts. This can be done using 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 is sometimes loosened. The screw must be twisted, which will affect the efficiency of the unit.
Sometimes the reason is also the swinging rubber cuff, which may be damaged. You can only see this fault if you disassemble the pump. This knot looks like a pair of saucers, which are located to each other by the 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 necessary if the swinging rod fails. This malfunction 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 act as a donor.
Major 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 with time, and then reaches a critical level. Then a short circuit of the turns occurs.
Damage 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 occurs during continuous operation. Threaded connections may lose strength due to vibration. If the thread has been loosened on the piston as well as the valve, then this cannot be seen with a simple inspection of the housing. The problem can only be solved by periodic prevention. All connections are regularly inspected by the master and tighten well.
The most frequent breakdowns and methods for their elimination
If you cannot cope with malfunctions yourself, then repair the Malysh pump in Moscow today. For example, you can contact "RemBytTehnika", which is located 8 km from MKAD. If you plan to carry out the work yourself, then first you need to figure out the cause of the breakdown.
Sometimes it also happens that the check valve with the piston has increased wear. To prevent such a problem, it is important to take 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 medium on the equipment. If you have such devices, then you may encounter a problem in the unit in the check valve. In order to eliminate the problem, when preparing the device for operation, it is necessary to adjust it. For verification, use a water barrel or other capacious container. It is important to achieve maximum pressure by changing the nut tension on the valve.
Conclusion
If you plan to carry out pump repairs yourself, then you must begin such work with the dismantling of equipment. This stage is almost one of the most difficult. The equipment case is two halves, which are pulled together by four bolts, so when disassembling, you may encounter certain difficulties.
