Pump shaft action of pipeline centrifugal pump

Sealing ring of pipeline centrifugal pump is also known as anti leakage ring. The gap between the impeller and the pump shell is too large, the pump shaft is connected by coupling and motor, the motor torque to the impeller in the pump will cause the high pressure zone of the water flow through the gap area of low pressure water pump efficiency and reduce the influence! Clearance is too small will cause the impeller and pump shell friction wear. Pipeline centrifugal pump in many manufacturers in the heart is still in favor of.
