(a) the pump can not be started

  One is after closing the motor does not turn without any sound. This shows that the circuit power supply circuit then impassibility, should check whether the circuit, whether insurance fuse, without exception is likely to burn out the motor stater winding, should remove line replacement. Another is that after closing the motor does not turn and accompanied by a "buzz" sound. This case should be immediately shut down inspection. The reason is that there is a 1 power line or the stater winding is not a phase, the formation of phase. 2 voltage is too low. The reason is that the power supply voltage is low, the cable is too long and the section is too small, transformer capacity is too small, should be one by one investigation. There are 3 foreign bodies in the pump body, bearing damage death card, "package axis" and "killed" phenomenon, should the proposed clean water pump inspection.

(b) no water, little or no water after the start of the pump.

  The fault reasons are: 1 parts such as water flow, water diversion tube, shell and other components seriously blocked or water pipe rupture. At this time often appears to increase the current meter readings and pointer swing. Should be immediately shut down for inspection and cleaning up. 2 the normal operation of the motor but the amount of water is less. The reason is not reasonable pump configuration, the actual head compared with the pump rated head is too much, the need to replace a higher lift pump. Also may be a pump reversal, only the lead out of any two can be adjusted relative to. If the sealing ring or impeller excessive wear and tear, should be removed in time to replace the. 3 motor running normally but not water, the main reason is that the water level in the pumping process is too low, can be transferred to the valve of the water pipe or the water pump will be put to the following half meter.

(c) the unit turns violent vibration noise

  The reasons are: the guide bearing wear

1 pump shaft, in bearing swing, or shaft bending caused by eccentric wear, the current meter degree increases, the pointer swing violently, vibration, should immediately stop replacing the guide bearing or shaft straightening.

2 impeller fastening bolts loose, impeller and guide shell collision friction, causing the pump body vibration, should be suspended from the pump, tighten the bolt.

3 thrust bearing wear, so that the front baffle plate and the flow guide pipe friction, the current table pointer swings violently. There is a clear friction, should be replaced immediately thrust bearing, impeller wear should be replaced when the impeller.

4 the motor rotor and the pump rotating part of the balance is not qualified, the rotation of the unit vibration. Should take out the motor rotor and pump impeller into action, static balance test, so that it can reach the equilibrium state.
