How to turn a screw pump manually?
Thread Content
As the title suggests, the crude oil pump in our facility is a screw pump. How does one turn such a screw pump? What should I pay attention to?
Pay attention to it; it should be no different from turning a centrifugal pump’s impeller
Are there any other ways to turn the screw pump? The screw pump cannot be emptied.
Reply to 2# 328104062: Our screw pump is connected by a back gear, not by a coupling like that used in centrifugal pumps. Moreover, the pump shaft is very thick, so ordinary pipe wrenches cannot handle it...
Is there anyone here? Why isn’t anyone answering? ===ing...
Reply to 5# wangym521: Single screw or double/triple screw?
Reply 6# lwmmking is of the twin-screw type
I really don’t understand. Is there anyone skilled who can give me some guidance?
Remove the motor cover and rotate the motor fan, and that’s it.
For pumps with large shaft journals, there are specialized turning tools (with straps) available, which are very convenient
If the flower pads are connected, there will be gaps; a crowbar can be used to pry at those gaps in order to turn the shaft
