Form of failure	Causes	Troubleshooting
Self-suction oils are not pumped.	1. There is no liquid storage or insufficient liquid storage in the pump casing. 2. Air leakage in suction pipeline 3.Speed is too low 4.Suction Lift is too high or suction pipe is too long 5. Mechanical seal leakage is too large 6. The gas in the suction line cannot be discharged from the Outlet.	1.Add enough reservoir fluid 2. Check and eliminate air leakage 3.Adjust Speed 4. Lower the Suction Lift or shorten the suction line 5. Repair or replace 6. Let it drain out
The self-suction pump noise and vibration are high	1. Unstable feet 2. The pump shaft is bent 3. Cavitation phenomenon 4. Bearing wear is serious 5. Miscellaneous items in and out of the pipeline 6. The main shafts of the pump and the motor are not concentric	1. Reinforcement 2. Replace or correct 3.Adjust working conditions 4. Replacement 5. Remove debris 6.Adjust coaxiality
There's not enough fuel to pump.	1. The impeller flow channel and suction pipe are blocked 2. The impeller or impeller seal is severely worn 3. Insufficient power or too low speed	1. Remove blockages 2. Replace the mouth ring 3.Add enough Power and adjust to rated Speed
Self-suction pump axle Power It's too much.	1.Flow is too large 2.Speed is too high 3. The pump shaft is bent or the impeller is stuck 4. The flow passage in the pump is blocked or stuck	1. Increase outlet pressure 2. Reduce appropriately 3. Replace or correct 4. Queue blockage
