Three screw pump working principle and characteristics

Three screw pump basic working principle: Three screw pump is the use of screw rotation to suction and discharge liquid. The middle of the screw for the active screw, driven by the prime mover rotation, the screw on both sides of the driven screw, with the active screw for reverse rotation. Due to the mutual engagement of the screws and the tight fit of the screw with the inner wall of the liner, one or more sealed spaces are separated between the suction and discharge of the pump. As the screw is rotated and engaged, these sealed spaces are constantly formed at the suction side of the pump, the liquid in the suction chamber is enclosed therein and continuously displaced in the axial direction of the screw from the suction chamber to the discharge end, to be enclosed in the spaces Liquid is continuously discharged as if a nut is continuously pushed forward when the thread is rotated. Characteristics: The screw seal line that the stator contacts the rotor is completely separated from the discharge cavity, so that the pump has the function of blocking the valve to realize the liquid, Gas, solid multi-phase mixed pump fluid flow does not change the volume, there is no Swiss flow agitator and the formation of vented stator cavity can effectively reduce the transport of solid particles containing medium wear medium viscosity of up to 50000Mpa · s with a solid content of up to 50% of the flow rate is proportional to the speed with the governor can be achieved automatically adjust the amount of pump can be positive and negative transport.
