Reasons and treatment methods of submersible pump running vibration

The violent vibration operation of submersible pump and water pump impeller and motor rotor balance and mechanical reasons

( 1 ) the unbalanced rotor processing method of removing motor, dynamic balancing of rotor.

( 2 ) the pump impeller is not balance method is static balance to pump impeller.

( 3 ) the shaft bending which is a serious fault, will make the air gap motor bearing force is not uniform, deterioration, or will make the motor stator and rotor rub, produce severe vibration diving pump is running, should be an immediate overhaul, the shaft alignment bending.

( 4 ) bearing wear processing method is to replace the rolling bearing and water lubrication bearing and the shaft sleeve is damaged.

( 5 ) the connecting flange and the bolt loosening treatment is tighten loose bolts, so the flange connection.
