Form of failure |
Causes |
Troubleshooting |
|
The pump does not produce water |
water pump reverse Air leakage in water pipes There is too little water in the pump chamber The voltage is too high and the coupling slips when starting. Suction Lift is too high |
Change Motor wiring No air leakage in society Increase water storage capacity Adjust Voltage Lower the pump installation position |
|
Insufficient Flow |
Suction pipe diameter is too small Impeller flow path blocked Head is too high Speed too low |
Replace water inlet pipe Clean impeller Open the water outlet valve Huixia rated Speed |
|
Head too low |
Flow is too large Speed too low |
Close the water outlet valve Restore rated Speed |
|
The sound is too loud |
Shaft severely worn Shaft sleeve severely worn The driving magnetic steel cup is in contact with the isolation sleeve |
Replace pump shaft Replace shaft sleeve Disassemble the pump head and reassemble it |
|
Leakage |
Type 0 sealing ring is damaged |
Replace Type 0 sealing ring |
