机械密封损坏， o 型圈损坏导致水泵泄露。
ISG vertical centrifugal pump selection is a concern of many friends, the modern era has changed, so we suggest that you can choose ISG vertical centrifugal pump through the network. It's also more convenient to buy.
Insufficient water injected into the pump, incorrect rotation direction and blockage of impeller passage are all the reasons that cause the pipeline pump not to water.
The pump is partially blocked, the speed is too low, the total lift is higher than the rated value of the pump, and the impeller damage results in insufficient flow of the pump.
There is air in the liquid, the speed is too low, the impeller is damaged, and the outlet valve is too large, which results in insufficient outlet pressure.
Mechanical defects such as too small operating clearance, motor shaft bending, bolt loosening lead to excessive power consumption of the pump, ___________
The impeller blockage causes unbalance and cavitation, which results in pump vibration.
The mechanical seal is damaged and the O-ring is damaged, which leads to the leakage of the pump.
Bearing overheating and oil shortage, pump overload leads to excessive noise.
