Fault phenomenon | Possible causes | Exclusion method |
A.The inlet and outlet valves are not opened, the inlet and outlet pipelines are blocked, and the runner impeller is blocked B.The running direction of the motor is wrong, and the speed of the motor is slow due to the lack of items C.Air leakage of suction pipe D.The pump is not filled with liquid and there is air in the pump chamber E:The inlet water supply is insufficient, the suction head is too high, and the bottom valve leaks F:The pipeline resistance is too large and the pump selection is improper | A:Check and remove obstruction B:Adjust the motor direction and tighten the motor wire C:Tighten all sealing surfaces to remove air D:Open the pump cover or open the exhaust valve to exhaust air E:Shut down for inspection and adjustment (this phenomenon is easy to occur when the grid connected water pipe is used with suction head) F:Reduce the pipeline bend, re select the pump | |
A:Press 1 to check the cause B:The pipeline and the impeller of pump passage are partially blocked, and the valve opening is insufficient due to scale deposition C:The voltage is low D:Impeller wear | A:Press 1 to exclude B:Remove the blockage and readjust the valve opening C:Voltage stabilization D:Impeller replacement | |
A:Use in excess of rated flow B:Suction head too high C:Pump bearing wear | A:Adjust the flow and close the outlet valve B:reduce C:Replace the bearing | |
A:Unstable pipeline support B:Liquid mixed with gas C:Cavitation is produced D:Bearing damage E:Motor overload operation | A:Secure the piping B:Increase suction pressure, exhaust C:Reduce the vacuum D:Replace the bearing E:Adjust by pressing 5 | |
A:Excessive flow, overload operation B:local friction C:Motor bearing damage D:Insufficient voltage | A:Turn down the outlet valve B:Check and eliminate C:Replace the bearing D:Voltage stabilization | |
A:Wear of mechanical seal B:There are sand holes or cracks in the pump body C:Uneven sealing surface D:Loose bolt installation | A:replace B:Welding repair or replacement C:Trimming D:Tight confinement |
