Screw pump is a kind of internal rotation eccentric rotary displacement pump. Screw pump according to the number of pump into single screw pump, twin screw pump and three screw pump. A single-screw pump consists essentially of a single-headed screw rotor and a stator with a double-ended screw, usually made of an elastic material. As the rotor rotates in a circle about the axis of the stator within the cavity, the enclosed wrist formed between the stator and rotor is displaced along the helix of the rotor, so that the medium is continuously, uniformly, and constantly withdrawn in volume Mouth to the pressure out. In this case, single screw suitable for working in what environment? 1, conveying high viscosity medium: According to the size of the screw pump can deliver viscosities from centipoise medium. 2, medium containing particles or fibers: the particle diameter can be 30mm (not exceeding the rotor eccentricity). The fiber length can be 350mm (equivalent to the pitch of 0.4 rotor). Its content is generally up to 40% of the media pit, the medium if the solid matter is a fine powder, the maximum content of up to 60% or more can also be transported. 3, requiring delivery pressure stability, the inherent structure of the medium do not love to destroy.
