1, the operation of the pump should always observe the flow of current, voltage meter and water, and strive to operate under rated conditions.

2, the application of the valve regulating flow, head shall not overload operation.

There is one of the following conditions: 1) immediately stop operating current exceeds the rated value of the rated voltage;

2) under the rated head, the flow rate is lower than the normal;

3) insulation resistance less than 500 billion ohm;

4) when the moving water level falls to the pump suction port;

5) electrical equipment and circuits are not specified;

6) the electric pump has a sudden sound or a larger vibration;

7) protection switching frequency trip.

3, should always continue to observe the instrument, check the electrical equipment every half a month to measure the insulation resistance, the resistance value of not less than 500 billion ohm.

4, each irrigation period (2500 hours) for a maintenance protection, the replacement of wearing parts for.

5, lifting and handling of electric pump:

1) disconnect the cable, disconnect the power supply.

2) with the installation tool gradually removing outlet pipe, valve, pipe, and pinch plate under the tight section of the water pipe, which in turn, remove the pump by hanging out well. In the process of lifting (found stuck can not be forcibly lifting, should be up and down about customer service card safe hoisting and unloading activities.

3) remove the support plate, and water from the lead and three core cable or flat cable connector cable cut.

4) remove the locking ring of the shaft coupling, screw down the fixing screw, remove the connecting bolt, and separate the motor and the water pump.

5) out of the motor water filling.

6) pump disassembly: disassembly wrench, remove the left inlet section, remove the tube in the pump with lower impact tapered sleeve, impeller loose, remove the impeller and the conical sleeve and remove deflector shell, which in turn is discharged in an impeller and a diversion shell, guide housing, check valve etc..

7) motor removal: in order to remove the base, thrust bearing, thrust plate, the lower guide bearing seat, water, remove the rotor, remove the bearing seat, stator and so on.

Electric pump assembly:

(1) the assembly sequence of the motor: the stator assembly, the lower guide bearing assembly, the rotor assembly, the thrust plate, the left fastening nut, the thrust bearing assembly, the base assembly, the upper guide bearing seat assembly, the skeleton oil seal and the connecting seat. Adjusting stud, so that the motor shaft extends to the specified requirements. A good film, then adjust the pressure adjusting spring and a cover. (2) pump assembly: the axis and the inlet section will be fixed on the seat I can hold, the impeller and the conical sleeve is fixed on the shaft with removable cylinder, and then loaded on the diversion shell and impeller Bahrain.. so...... the upper shell, check valve etc.. The following eight departments of motor and pump assembly, first in the water Festival and on the bearing seat through the contact plane between the uniform on the tension nut mounted on the shaft coupling, pump shaft, a fixed stud and a lock ring, with the tide of the impeller and the conical sleeve barrel is fixed on the pump shaft, is arranged on the guide housing this in turn, impeller...... Bahrain on diversion shell etc.. Pump installed after pulling the nut, remove the gasket, the lacing nut tightened evenly, then turn the pump from the coupling, the rotation must be uniform.
