After the stainless steel submersible pump is installed and used, it will trip automatically after a period of time and start it immediately without any response. It can start again after waiting for a few minutes to ten minutes. Why is this: when purchasing a stainless steel submersible pump, the model is not selected correctly: the actual head used is relatively low, the head of the selected stainless steel submersible pump is too high, and the working conditions do not meet the scope of use of the selected sewage pump.
　　




The power supply voltage used on site is unstable: stainless steel submersible pumps are especially used with 220V sewage pumps in rural areas. The voltage in many areas in rural areas does not reach the standard voltage, which causes the current in the pump motor stator winding to increase more, which leads to the stator winding The temperature rises too much and the motor is burned out.
　　
Mechanical failure of the stainless steel submersible pump: the bearing of the stainless steel submersible pump is seriously damaged, the stator and the rotor are rubbed "sweeping" or the pump body is blocked by debris, and the impeller is stuck and other mechanical failures will cause the stainless steel submersible pump to always overload and trip. .
　　
The stainless steel submersible pump has a problem when it leaves the factory: the stainless steel submersible pump is overloaded due to quality reasons in the manufacture and repair of the stainless steel submersible pump. Therefore, when the stainless steel submersible pump has tripped, after troubleshooting the model problem, check the power supply voltage, bearings, etc. according to the conventional method to ensure that the machine runs without problems.
