The self balance multistage centrifugal pump developed in- dependently by our company was revolutionized in its structure,has no need of balance disc or drum for counterbalancing the axial force,and offers safer and more reliable operation condition,without frequent displacement of balance device,wear-and-tear and failure of mechanism,and steam friction which would take place in the traditional centrifugal pump.Adoption of the patented technologies for hi-pressure self-balance sectional centrifugal pump(Patent No.:ZL03.2.351.1)and ni-pressure multistage pump combined seal (Patent No.:ZL03.3502.X)increases more technical superiorities.
This type of pump is widely used for delivering water containing up to 5%wt solids of grain size less than 0.2mm and media similar to water in physical property in such applications as petrochemical medium transfer the descaling of hot rolled steel, water injection of oilfield,crude oil transfer,chemical product,boiler feed,mine drainage,coal mining,etc.
2,Structural features
Opposed impeller arrangement provides permanent axial hydraulic balance without balance disc or drum,and the bearing set bears transient axial thrust and residual axial force due to the avoiding the shaft breaking and other serious faults resulting from failure of the balance device due to fluid containing solids or steam friction at high-temperature.This makes the pump operate smoothly and reliably under any extreme operating conditions.ZDF Section
