1:The pump does not absorb water, the pressure gauge and the vacuum gauge jump violently
Reason:
1).Poured traction water not enough.
2).Leakage of pipe and instrument connection.
3).Suction is too high.
Solution:
1).Check for water leakage.Poured traction water.
2).Tighten the bolt.
3). Reduce the suction height.
2:small flow rate
Reason:
1).Multistage centrifugal pump inlet has air intrusion.
2). The low water level.
3). The impeller has blocked.
4) sealing serious wear and tear.
Solution:
1).Check pipeline.
2). Extend inlet pipe.
3). Remove and remove garbage.
4). Replace seal.
3:The pump consumes more power
Reason:
1).Sealing bolts are too tight.
2). Excessive flow of flow.
3). Contact.
4). of impeller and pump body. Pump bearing wear.
5). Pump shaft bend.
Solution:
1).Adjust valve.
2). Repair impeller and pump body position.
3). Replace bearing.
4). Replace pump shaft.
4:Pump vibration increase
Reason:
1).Impeller block.
3) impeller damage. Traffic tailed.
4). The pump shaft and motor is not in horizontal line.
5) bearing damaged.
6). Inhaled air
Solution:
1).Remove and remove garbage.
2). Change the impeller.
3). Open the valve.
4). The recalibration.
5) improve the inlet line.
