The reason and solution of the sudden stop of pump

The pump suddenly stops running, this situation is more common in practice, but many people do not know the reasons for this failure, so when the first use of the pump, encounter this kind of problem, the first reaction of water quality problems, in fact, there are many reasons why this kind of problem, mostly caused by improper use or selection, how to determine the cause of the problem and the solution? Shanghai Welpump for everyone to do a small summary:
1, when in the selection of self suction pump, suction pump caused by excessive long time idling, the liquid does not suck up. So in the choice of self priming pump, be sure to determine the suction height of the pump, can meet your needs.
2, the impeller or the impeller of the centrifugal pump is a serious blockage. This situation is in use for a period of time, as a result of the liquid pumping impurities particles, leading to the impeller of the centrifugal pump has been blocked. Before the election, you must first find out whether the liquid contains particulate impurities, to facilitate customer service to you to choose the right pump.
3, the pump to produce air or at the entrance of the pipeline, there is a leak of the situation. Pump leakage will cause leakage of the pump can not be pumped out of the liquid, especially for the self suction pump, imports if the leakage of liquid certainly does not suck up, be sure to seal the pump inlet pipe.
4, packing gland or seal is not strict, there is wear and tear, lead to air leakage into the pump casing. For example, G single screw pump for a long time without a change of wearing parts, you need to check is not wearing parts, including mechanical seal or packing.
5, in the pumping heat or play in the process of liquid suction head is insufficient. Ensure adequate inlet head of the pump, the liquid is too small, the pump is easy to overload, leading to pump stop.
6, valve or entrance tube immersion depth of the problem. This situation is similar to the fifth, that is, the pump is not enough water or air pump suction does not come up, so that the motor overload resulting in parking.
The gasket 7, pump shell damage, this is more common, because a lot of pump seals are used in rubber if pumping the liquid when the temperature or corrosive, such as IHF fluorine pump, used for a long time will cause corrosion of seal or gasket aging, so that pump leakage, leakage.
All of these may cause the pump running in no reason to stop, affect the efficiency of the work. So in our daily work, mainly to check the existing static head, look at the entrance of the pipeline is reasonable, to see whether there are obstacles between devices to inspect, entrance pipeline and the existence of cavitation packing or seal timely inspection and replacement, regular lubrication, increase the suction head, timely communication with suppliers to solve the problem, the use of baffles to eliminate eddy current, in accordance with the provisions of the specification of the strict control of the depth of immersion, we cannot ignore the mat lady check the seal, in accordance with the requirements of the timely replacement.
