1.After starting the pump does not water :
Solution: adjust the pump to the steering, and check to reduce the speed of the reasons, to be clear, to eliminate the pipeline leakage.
2.Water pump out of the water shortage :
Solution: in accordance with the provisions of the manufacturers to modify, improve working conditions; check and adjust the blade angle, replace the impeller or impeller pump body section, or to take measures to repair welding.
3.Motor overload:
Solution: select machine, repair or replacement of bearings or shaft, blade angle adjustment, not to overload, replace the power or replacement of the impeller, the pump speed is reduced to the rated value; replace the water pump or open the valve on the pipeline.
4.Pump in the operation of vibration and noise:
Solution: increase the depth of submergence, replacement of the impeller in the pool water surface with wood, foundation reinforcement or tighten the anchor bolts, replace the coupling or stop tightening screws, replacement of rubber bearings or bearing contact spray in hard chromium plating, increase the pool to rearrange the pump position, re calibration of pump shaft.
Motor overload, insufficient water pump, water pump, water pump start after running vibration and noise of axial flow pump failure is more prone to the work process, the timely processing of these faults, not only to protect the axial flow pump, it is more important in order not to delay the work schedule and work efficiency. Equipment used more or less will meet the fault, the fault is sometimes not terrible, terrible is to meet the problem can not be solved.
