Analysis of Common Faults and self-priming pump overhaul
Date:2016/6/13 Number:4018

Self-priming pump in daily use will be some glitches, Kowloon Pump Manufacturing Co., Ltd. now to give you a brief analysis of some of the self-priming pump failures of some repair work.

Stainless steel self-priming pump motor section

1, no reaction after the power is turned on. Most of the power plug, power outlet and motor windings due to short circuit.

2, difficult to start or not start, and accompanied by "buzzing" sound. Available in small bamboo overhaul by running direction quickly toggle fan, if the motor up and running quickly, indicating that the start capacitor start winding or damaged, replace or repair the same capacity capacitor start winding; if motor issuers, mostly motor and pump head mechanical failure, such as damage to the bearing, the impeller stuck like.

3, the motor can operate, but the speed is slow, and chassis overheating, there is a burning smell. Most of the motor winding short circuit caused by the motor should be open, depending on the damage were welding, jumper, isolation, rewind and other measures to repair.

4, when a large operating noise, vibration. Most of bearing damage or the bearing housing and fit properly, need to open the motor check if bearing damage should be replaced; if run cylindrical bearings, the pump casing mating surface using engraved handle; if the bearings run inside the circle, can be wear parts for motor shaft using engraved handle, badly worn, turning after first using the method welding repair.

Stainless steel self-priming pump pump head part

1, the normal operation of the motor, but simply no water or less water. This situation should first check the pump seal check should unplug the power cord, hand to block the mouth water, the pump filled with water, mouth Xian Zhu outlet inside hard blow, observe the pump head is leaking, leaking which is sealed at the place of damage. Common failure parts of absorbent pad opening, the outlet pad, impeller cover pad, maintenance should be replaced. Without phenomenon full of water, mostly in the retaining spacer etch damage the impeller, suction chamber and the outlet chamber of wear, pump head retaining barrier removed, the pump casing and impeller clearance increases, should replace the impeller and pump housing . Note that when replacing the wheel instep completely remove the residual copper vane pump, so as not to damage the new impeller again.

2, chassis charged. Most of seal damage, water infiltration inside the motor through the motor shaft of the motor insulation deterioration due to be used to replace the seal, drying and other methods to repair the motor. Note that, because the long-term contact with water pumps and outdoor work, damp and can easily cause deterioration of insulation properties, in order to ensure personal safety, electric stainless steel self-priming pump should be grounded.
