What are the common methods of balancing the axial thrust of a water pump?
The symmetrical arrangement of impeller.The balance disc device.The balance drum and two-way thrust bearing method.Adopts the drum with balance disc balance measures
Both sides of the impeller inlet.The impeller is installed on the cover plate of back blade, in addition, the extra axial thrust by the thrust bearing.The axial thrust balance method of multistage pump is as follows:
Single stage pump axial thrust balance method has:A sealing ring is arranged in the front and rear impeller, impeller cover plate is provided with a balance hole (the balance hole is generally from 4 to 6, a total area of five times on the sealing surface gap area) or a balance tube.
