The structural characteristics of screw pump
2H-type twin-screw pump can be divided into built-in bearings and external bearings in two forms.
At the same time screw and pump body, screw and screw between the formation of a sealed cavity, to ensure that the closed, otherwise there may be liquid back from the gap back.
Therefore, the pump body and screw outer surface and screw and screw gap should be as small as possible.
Twin screw pump as a positive displacement pump, the pump suction chamber should be closely spaced from the discharge chamber.
The twin screw pump is an externally engaged screw pump which utilizes two screws that are engaged with each other and do not touch each other to draw the liquid.
