Causes of axial turbulence in multistage pump

When the multi-stage pump is working, its rotor position is fixed to ensure: A. The impeller outlet is aligned with the center of the vane (or pump casing). B. The rotor components (such as the impeller) do not rub against the pump body.   The fixed method is: 1. A pump with a balance disc, the balance disc itself being a positioning device. Due to its automatic adjustment of the axial thrust, the rotor position is limited to a small variable range. 2. For pumps without balance discs,...
