What is the reason that the axial force of centrifugal pump is too large? What's the effect on the equipment?
1, generally in the multi-stage pump relatively easy to appear.2, stand-alone pumps rarely occur.3, because the axial force changes greatly, flat very often wear. Not for stainless steel.
4, the new pump: in addition to disk balance, and balance drum. Balance the axial forces by two sets of devices. The balance worked very well.5, the original pump only balance disc. The ability to balance axial thrust is poor.
The balance device may be out of order, the axial force is too large, axial movement increases, the impeller in the axial displacement, it is easy to hit the surrounding shell, and then in the high-speed friction damage.
