What are the reasons for rapid wear of the stator in screw pumps?

Why is a single-screw pump chosen for transporting clean water as a medium?
Bearing damage and positioning issues with the bearing housing can both cause this problem.
Plain water as a medium should not be suitable for screw pumps, right? Let’s just say I don’t know how you install it. Anyway, when I was installing it, if water was added to the rotor, it would become sticky and make installation very difficult. Then it’s easier to get in once we use soapy water
The bearing is broken, but it seems unlikely that all six pumps are damaged; the maintenance staff also failed to detect any issue.
It’s best to take a video to check the damaged area to see if it could be caused by cavitation. I only say it’s possible. The information you provided is incomplete, so I have to mention what I think might be the case in my answer. “For screw pumps, the stator wears out very quickly; firstly, there is definitely no casing material, and the medium is clean water. That was your original question. The best way to solve the problem is to be involved on-site, but that’s not possible; therefore, it’s necessary to provide the most comprehensive information. There’s no need here to blame anything like \"the bearings are broken; could all six pumps be damaged as well?\" Once again, Shen provides the most comprehensive information to facilitate problem-solving. With all due respect.
Why is a single-screw pump used for ammonia solution? I’m a bit confused
Is the medium clean? Does it contain particles? Has cavitation occurred? Send a photo: lol
Cavitation only occurs when a screw pump is used to pump clean water; corrosion is what causes wear. Centrifugal pumps are generally used for pumping clean water, while screw pumps are typically used for pumping dirty fluids
