Pump industry suppliers - Why are self-priming pump motor burning

why self-priming pump motor burning

general self-priming pump is not super traffic, not super power output is not easy to cause the motor burning, and the number of customers in the application and installation are many is not stipulated in the self-priming water pump manufacturer installed applications. Slack period specifications increase lead to reduced and water pump suction long-term high speed machine seal damage, water yield specification change communication lead to excess traffic, long-term operation will lead to motor burning, when electricity chance to destroy the worst.

self-priming sewage pump operation: hand rotating shafts can some tapes or buzzing noise condition, such as open pump above water gate, sign up for the two-thirds of the capacity of many liquid water in the pump shell, turn off the gate, then start without irrigation water again. Connected switch power supply, start-up, commissioning, when looking from the motor to turn clockwise. Start work, check whether can run everything is all right? If any abnormal situation, should find out why, various cleaning.

self-priming pump operation suddenly shut down how to solve the

1, the set of warm or volatile liquid inlet water is not enough; Expand the suction inlet, pump body sealing gasket destroyed; Check the condition of the sealing gaskets and to carry out the conversion in accordance with the regulations.

2, impeller or pipe wall; Check if there is any roadblocks. Cause gas or channel pipeline leak; There are no air pockets or gas leak inspection channels pipes.

3, the pump head of the pump is too high, super power flow; Adjust the entrance gate, driving school student driver traffic to reduce electrical flow.

4, self-priming pump bottom valve or channel tube immersed in deep; To the factory has proper immersed in deep, with clapboard clearance vortex.

5, the stuffing box filler or sealing damage, make the gas leakage into the pump body; Check the filler or sealing and press must be moved around. Inspection RunHua whether everything is ok.

before starting the self-priming pump need to be aware of:

1, naturally aspirated without infarction diving sewage pump and pipeline should be persistent excellent sealing.

2, check the water pump base, even the axis of standard parts, rolling bearing and docking position have loose? If you have any loose should be tight.

3, check the components have damaged in transport. Naturally aspirated without infarction submerged sewage pump itself does not allow for pipe support plate.

4, before type self-priming sewage pump equipment can check the foundation level.
