What Is Screw Pump

Screw pump is a positive displacement pump. The name gerotor comes from the generated rotor. A generator set consists of an inner rotor and an outer rotor. The inner rotor has n teeth, while the outer rotor has n+1 teeth; N is defined as a natural number greater than or equal to 2. The geometric shape of two rotors divides the volume between them into n different dynamically changing volumes. During the rotation cycle of the component, each of these volumes is constantly changing, so any given volume first increases and then decreases. Increasing will create a vacuum. This vacuum generates suction, so this part of the cycle is the position of the air inlet. As the volume decreases, compression occurs. During this compression period, liquids can be pumped, or if they are gaseous liquids, they can be compressed. The design of a toothed disc pump usually uses an inner rotor and an outer rotor composed of intersecting arcs. Screw pump can also be used as a rotary engine without piston. High pressure gas enters the inlet and pushes the inner and outer rotors, causing them to rotate as the volume between the inner and outer rotors increases. During compression, the exhaust is extracted.
