1. Mud pump suction operation, the pump should be vertical placement, the pump shell should be all buried in mud; if used for pumping mud, should remove the pump cover at the inlet of the filter cover.
2. Before the start should first check whether the motor line is connected, reliable grounding; pulled by hand to see whether the pump shaft coupling, flexible rotation, no seizure and abnormal noise; if there is not a normal phenomenon, should be excluded.
3. Because of the larger starting current, so the start action should be agile, to prevent erosion contact; observe the pump shaft rotation direction after the start, if it is found that the pump shaft reverse, immediately cut off the power, any two wire exchange three-phase motor, can change motor steering.
4. In the unit operation process, should pay close attention to the motor and pump abnormal noise and vibration; check whether the temperature of the bearing parts due to high and hot (generally not more than 35 DEG C); if abnormal should immediately stop check, troubleshooting before it can continue to work.
5. Regularly check the pump on bearing technology, bearing and lubricating oil cleaning in a timely manner; regularly check whether the oil seal wear, the coupling buffer block is intact, the bolt is loose; regularly check the motor winding, if the phase insulation resistance less than 380 billion ohm, should be dried.
