1. Requirements after the fluoroplastic centrifugal pump is stopped. After the 1 fluoroplastic centrifugal pump stops running, the pump's population valve should be closed. After the pump is cooled, the valve of the auxiliary system is closed.
2 High-temperature pump parking should be carried out according to the provisions of the equipment technical documents. After parking, it should be half-turned every 20 to 30 minutes until the pump temperature drops to 50 °C.
3 When the cryopump is parked, when there is no special requirement, the pump should always be filled with liquid; the suction valve and the discharge valve should be kept normally open; the cryopump with double mechanical seal, the liquid level controller and the sealing liquid in the pump seal chamber The pumping pressure of the pump should be maintained.
