Screw pump And screw pump are two kinds of pumps commonly used in fluid conveying equipment. They all use the centrifugal force generated by the rotating screw to push or compress the liquid.

First of all, in terms of structure, the main difference between screw pump and screw pump lies in the structural form of screw. The screw pump is mainly composed of one or more screws and casings, usually double screw or triple screw, while the screw pump is mainly composed of a closed spiral shell and a spiral rotor, usually single screw. The screws of the screw pump mesh with each other to form a closed cavity, while the gap between the spiral shell of the screw pump and the rotor forms a compression area. COLFAX agent

Secondly, from the working principle, screw pump and screw pump also have some differences. The screw pump pushes the liquid from the suction end to the discharge end through the rotating screw, so it is suitable for conveying low viscosity clean water or liquid containing certain particles. The screw pump has a strong conveying capacity and can transport high viscosity liquid with stable flow and pressure. The screw pump compresses the liquid through the rotating screw rotor and pushes it to the outlet, which is suitable for conveying high viscosity liquid, especially the paste with high viscosity. The screw pump has small conveying capacity but high pressure, so it is suitable for conveying with high process requirements. CIRCOR SECCO

In addition, screw pump and screw pump have some differences in the scope of use. Screw pumps are widely used in petroleum, chemical, food, pharmaceutical and other industries due to their simple structure, small size, low noise, easy maintenance and other characteristics. The screw pump is mainly used in petroleum, chemical industry, paper making, power and other fields due to its strong adaptability, good wear resistance and other characteristics, especially for liquid and paste materials with high suspended particle content.

In addition, there are some differences between screw pump and screw pump in terms of performance parameters. Screw pumps usually have higher screw speed and flow, but lower pressure can achieve relatively large conveying capacity. The screw pump usually has a lower speed and flow, but a higher pressure can achieve higher pressure transmission. Viking

To sum up, there are some differences between screw pump and screw pump in structure, working principle, scope of use and performance parameters. According to the specific transportation needs and process requirements, selecting the appropriate pump type can better meet the production needs.
