Motor section
1. No response after power on. Most of them are caused by short-circuiting of power plugs, power outlets, and motor windings.
2, difficult to start or can not start, and accompanied by "squeak" sound. During inspection and repair, small bamboo strips can be used to rapidly move the blades according to the running direction. If the motor is quickly operated, it indicates that the starting capacitor or starting winding is damaged. Replace the capacitor with the same capacity or repair the starting winding. If the motor is issued, the motor and the pump head are mostly. Mechanical failure, such as bearing damage, stuck impeller and so on.
3, the motor can run, but the speed is slow, and the chassis is overheated, burned odor. Most of them are caused by the short circuit of the motor windings. The motor should be disassembled and repaired by welding, jumper, isolation, rewinding, etc., depending on the damage.
4, large noise and vibration during operation. Most of the bearings are damaged or the bearing and the chassis are not properly mated. The motor must be dismantled and inspected. If the bearing is “out of circleâ€, the mating surface of the pump casing can be used to decorate it; if the bearing “runs inside "Circular" can be used to decorate the worn part of the motor shaft. The wear is serious and it is repaired by lathing after welding.
Pump head section
1. The motor runs normally but has little or no water. This situation should first check the seal of the pump, check the power plug should be unplugged, hand plug the suction port, fill the water pump, with the mouth to seal the exit and blow in the air, observe the pump head is leaking, leaking The place is where the seal is damaged. Common faults include suction pad, outlet pad, and impeller cover pad, which should be replaced during maintenance. If there is no full water phenomenon, the impeller is damaged, the water-retaining partition between the water-absorbing chamber and the outlet chamber is worn out, the pump head is covered with water, and the gap between the impeller and the pump casing is increased. The impeller and the pump casing should be replaced. . When replacing the rake wheel, care should be taken to completely remove the remaining copper blades in the pump so as not to damage the new impeller again.
2, the chassis is charged. Most of them are damaged by water seals. Water penetrates into the motor through the motor shaft and deteriorates the insulation performance of the motor. It can be repaired by replacing the water seal and drying the motor. It should be noted that because the water pump is exposed to water for a long time and it is open to work in the open air, it is vulnerable to moisture and deteriorates the insulation performance. In order to ensure personal safety, the electric self-priming pump should be reliably grounded.
