Multistage pump shaft channeling large change, pump operation suddenly interrupted
The key to the second scheme is to design the balance drum reasonably so that it can balance most of the axial forces. For other single-stage pumps, pumps and other products in the design, to take some measures to ensure that mining multi-stage pump shaft pump in the mechanical seal within the required range.
The other is the balance drum and axial thrust bearing, which balances most of the axial force by the balance drum. The remaining axial force is borne by the thrust bearing, while the axial thrust bearing axially limits the pump shaft.
In this case, the following method can be used to eliminate the shaft channelingOne is the balance plate and axial thrust bearing, the balance plate balances the axial force, and the axial thrust is limited by axial thrust bearing;
