Determination of pump crosshead movement
Thread Content
Are there any standards regarding the clearance between the rotor and the magnetic cylinder in single-stage, single-suction centrifugal pumps and magnetic drive pumps, and how can this clearance be determined?
For this main parameter, it is still necessary to refer to the standard parameters specified in the manual. Usually, it depends on the bearings he uses, or the allowable clearance of the straight-thrust bearings in the bearing bushes. In short, the data within the specifications outlined in the manual should be taken as the standard.
Hello, sea friend! I think it’s necessary to confirm the size of the pump; the clearance in a larger pump must be greater than that in a smaller one. So it can’t be generalized. It is recommended to consult the original pump manufacturer.
This momentum must be compatible with the thermal expansion and contraction of the components as well as with the thickness of the liquid film.
