In electroplating, electronics, chemical industry, leather, dyeing and finishing, waste water, waste gas and other fields, plastic horizontal self-priming pump plays a great role.However, in operation, the plastic horizontal self-priming pump sometimes appears noise, so what are the reasons for the noise, and what are the treatment methods?
1. Motor reversal.(adjust motor wiring sequence and make it turn forward)
2. Impeller friction or impeller twisted to foreign body, cover and vibration in friction.(open the main body, check whether the impeller is damaged, treatment: clean up or replace)
3 into the air, playing a lot of sound.(check the inlet and outlet pipes and joints, the sealing position of pump suction inlet is wrong, and the possibility of air inlet is found and repaired in time)
4. Bearing damage, harsh sound.(replace with new motor bearing)
5 axis eccentric, rotating, seal contact surface of the left and right friction swing.(disassemble and re-align the axis)
