As a positive displacement pump, the suction chamber in the pump should be closely separated from the discharge chamber. This requires the pump body and screw outer surface and screw and screw clearance should be as small as possible. At the same time, the screw and the pump body, the screw and the screw form a sealing cavity to ensure that it is sealed, otherwise there may be liquid flowing back from the gap. The unique structure of the double screw pump makes it possible to achieve no stirring, no pulsation, smooth transport of various media; Because the pump structure ensures that there is always pumping liquid as a sealing liquid in the working element of the pump, the double screw pump has a strong self-priming capacity and can be mixed with steam and liquid. The special design of the double screw pump also ensures that the pump has a high suction energy, namely a small NPSHr value.
