Twin Screw Pvc Pipe Machine

As the pump rotates, the intermeshing of the two contra-rotating screws, along with the pump housing, form volumetric chambers. These chambers fill with the pumped fluid and move it axially from the suction side of the pump to the higher pressure discharge side of the pump.A twin screw extruder is a machine consisting of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. The screws are tight and self-wiping, which eliminates stagnant zones over the entire length of the process section. This results in high efficiency and perfect self-cleaning.Twin screw extruders are principally used for specialized applications such as devolatilization, pumping thermally sensitive materials, ingredient mixing (compounding), and reaction chambers for mixing and transport of viscous materials.
