Working principle of screw pump

 

The single screw pump is a closed screw pump with internal meshing, which is a rotor type positive displacement pump. The main working components are composed of a stator with a double-headed spiral cavity and a single-headed spiral screw that meshes with the stator hole, that is, the rotor.

 


When the input shaft drives the rotor through the universal joint to make planetary rotations around the stator, the stator and the rotor pair continuously mesh to form a sealed cavity. The volume of these sealed cavities keeps moving at a uniform speed. The input medium flows from the suction end through the stator-rotor. It is transported to the extruding end, and the medium input into the sealed cavity flows through the stator without being disturbed or destroyed.

 


Therefore, it can transport media and viscous liquids containing hard abrasive impurities and solid particles. The single screw pump can be installed horizontally and vertically. The pump and the drive motor are connected by an elastic coupling or an intermediate transmission device and are installed on the same base. According to the needs of users to provide unit installation size.
