Which case is the screw pump

The screw pump is a volumetric pump with internal meshing eccentric rotation. The main components of the screw pump are a single-headed spiral rotor and a stator with a double-closed spiral usually made of elastic material. When the rotor is fixed in the cavity, the stator is wound around the stator. When the axis is rotated by the planet, the closed wrist formed between the rotating stators is displaced along the spiral of the rotor; therefore, the medium is continuously, evenly and continuously supplied from the suction port to the pressing end, based on this Features, single screw pump is especially suitable for the following working conditions.
Conveying high-viscosity media: Media with a viscosity of from 37,000 to 200,000 centipoise can be delivered depending on the size of the screw pump.
Media containing particles or fibers: The particle diameter can be 30 mm (not exceeding the rotor eccentricity). The fiber length can be 350mm (corresponding to the pitch of the 0.4 rotor). The content is generally up to 40% of the medium enthalpy. If the solid matter in the medium is a fine powder, the highest content can be as high as 60% or higher. When the conveying pressure is required to be stable and the inherent structure of the medium is not detrimental, the single-screw pump is most ideal.
