IMO screw pump It is widely used in the current chemical field. Screw pump There are many types, including single screw, twin screw, three screw, five screw, etc. Today, I will briefly introduce the working principles and differences of various screw pumps.
The classification of screw pump The screw pump is a volumetric rotor pump. Its principle is to pump fluid out through the displacement of several sealed cavities between the screw inside the pump and the pump sleeve. In the screw pump, it is strictly sealed that there is no theoretical leakage between two adjacent sealing cavities, rather than strictly sealed.
According to the field application and relevant data, the screw pump has stable flow, small pressure fluctuation, strong self-priming capacity, low noise, high efficiency, long life, small size and reliable operation. Its remarkable advantages lie in that no eddy current is formed when transporting media, various media with a wide range of viscosity are transported, non Newtonian fluids with large viscosity, strong corrosiveness, high viscosity and high viscosity are transported, and gas-liquid mixed transportation is conducted. This product is used in offshore platform engineering, petrochemical industry, shipping, electric power, mechanical hydraulic system, food, paper making, sugar making, military industry, sewage treatment and other industries.

The screw pump can deliver any medium. Of course, it does not mean that a screw pump can deliver all of them, but it should be selected according to the requirements of medium properties and performance parameters. Screw pumps are generally divided into single screw pumps, twin screw pumps Three screw pump And five screw pumps have their own advantages, but when promoting the use of screw pumps, we should make reasonable choices to make the screw pumps energy saving, material saving, benefit or meet certain specific needs, so that the screw pumps of screw pumps can have different performance.
The pump shell of the single screw pump is made of a non-metallic elastic material, usually rubber, with a spiral groove inside. The metal lead screw moves the seal chamber from the high-pressure position to the high-pressure area through eccentric rotation, completing the suction and discharge of liquid and the formation of pressure. In addition to conventional media, the single screw pump can also transport special liquids containing metal particles and fibers. When treating sewage and mud, single screw pump is generally used, and its working pressure is generally low.
