Application: Pump Parts
According to the mechanical structure, the impeller can be divided into three kinds: closed, semi-closed and open.
Closed impeller: conveying clean liquid;Semi-closed impeller and open impeller: suspension containing solid particles, low efficiency.When the closed impeller and the semi-closed impeller are running, the pressure of the liquid acting on the front and back of the impeller is different, which will produce axial thrust pointing to the impeller suction side, causing wear and vibration of the pump. After reducing the axial thrust by the balance hole, the pump efficiency will be reduced.
According to the different suction mode, the impeller can be divided into single suction and double suction.Single suction type: impeller structure is simple, but the liquid can only be inhaled from one side;Double suction type: complex structure, but with a large suction capacity, basically eliminate the axial thrust.
