[Asia Pump Network News] YG Vertical Pipeline centrifugal pump maintenance can be divided into two types of maintenance and mechanical seal maintenance, these two types of maintenance process has a different way, and now small series of these two Maintenance methods introduced one by one. YG Vertical Pipeline Centrifugal Oil Pump Maintenance (A) the operation of maintenance 1, the inlet pipe must be filled with liquid, the pump is prohibited long-term operation in the cavitation condition. 2, regularly check the motor current value, the motor may not exceed the rated current. 3, long-term operation of the pump, due to mechanical wear and tear, so that the unit noise and vibration increases, the parking should be checked, if necessary, replace the wearing parts, unit overhaul period is generally one year. (B) mechanical seal maintenance 1, mechanical seal lubrication should be clean without solid particles. 2, mechanical seal is strictly prohibited in the case of dry work. 3, before starting should be circling pump (motor) a few times, so as not to suddenly start causing graphite ring fracture damage. 4, sealing leakage tolerance 3 drops / min, otherwise it should overhaul.
