Publish: Browse:
Gear pump is one of the more commonly used in hydraulic systems. Not only should there be many precautions in use, it can't be placed there after use, and it must be cleaned and maintained. Now let's talk about the matters needing attention after the large flow gear pump stops running.
① If it is a pump that transports easily crystallized, easily solidified, and precipitated media, the large-flow gear pump should immediately flush the pump and pipeline with clean water to prevent blockage.
② The shutdown of the high temperature pump should be performed in accordance with the provisions of the technical documents of the equipment. After stopping, it should be turned for half a turn every 20 to 30 minutes until the temperature of the pump body drops to 50 ° C.
③ When the cryopump is stopped, when there are no special requirements, the pump should always be filled with liquid; the suction valve and discharge valve should be kept open; cryogenic pumps with double-end mechanical seals, liquid level controllers and the sealing liquid in the pump seal cavity The grouting pressure of the pump should be maintained.
④ After the centrifugal oil pump stops running, the inlet valve of the pump should be closed, and the valves of the auxiliary system should be closed after the pump has cooled down. Drain the liquid accumulated in the high-flow gear pump to prevent rust and frost cracking.
Different types of pumps should be checked according to different situations, whether they are blocked, rusted, etc., and relevant defense measures should be prepared to prepare for the next use.
