Hubei Chengli Group sprinkler pump common faults have two major categories
One, sprinkler pump head section
1. The motor runs normally but there is no water or very little water. In this case, firstly, check the sealing performance of the sprinkler water pump. When checking, unplug the power plug, close the suction port by hand, fill the sprinkler pump with water, and use the mouth to hold the outlet and blow it in. Observe whether the pump head is inflated. Leakage, where the leak is the seal damage. Common fault areas include impeller cover pad, outlet pad, and suction 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.
Second, sprinkler motor part
1. No response if power is turned on. Most of them are caused by short-circuiting of power plugs, power outlets, and motor windings.
2, if the motor is difficult to start or can not start, and accompanied by a "click" 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, if the motor can run, but the speed is slow, and the chassis is overheated, there is charred odor. Most of the motor windings are short-circuited. The motor is disassembled and repaired by means of welding, jumper, isolation, and rewinding, depending on the damage.
4, if the motor is running, the noise is large and the vibration is great. Most of the bearings are damaged or the bearing is improperly mated with the chassis. Check the motor for disconnection. If the bearing is damaged, replace it. If the bearing runs in a circle, the worn portion of the motor shaft may be damaged. The wear is serious. After the method of turning repair. If the bearing runs out of circle, the matching surface of the pump casing can be used for stencil processing. If none of the above methods can solve the problem of the sprinkler pump, please contact the after-sales department of the sprinkler manufacturer to solve it for you by a professional engineer!
