Screw Vacuum Pump

What is Screw Vacuum Pump?

A screw vacuum pump is a pump that uses a screw rotor to rotate and compress in the pump chamber to transport gas. Its working principle is that through the rotation of a pair of screw rotors, the gas in the pump chamber is compressed and discharged, thereby achieving air extraction and exhaust. Screw vacuum pumps have the advantages of simple structure, easy maintenance, and high reliability, so they have been widely used in the industrial field.

The characteristics of screw vacuum pumps include high pumping rate, low ultimate vacuum, low energy consumption, etc. It can be used in vacuum applications in various processes, such as pharmaceuticals, fine chemicals, new materials, oil and gas recovery, VOC exhaust gas treatment, environmental protection, food and beverages, starch sugar making, vegetable freeze-drying and other fields. At the same time, the screw vacuum pump can also be used in conjunction with other vacuum equipment, such as Roots vacuum units, oil diffusion vacuum pumps, etc., to achieve a more efficient vacuum system.

The screw vacuum pump has a compact structure, high efficiency, high reliability and easy maintenance. When selecting a screw vacuum pump, you need to consider its working pressure, flow, temperature, medium and other parameters, as well as its installation and operating environment and other factors. In addition, in order to ensure the stable operation of the screw vacuum pump and extend its service life, regular inspection and maintenance are required, and attention should be paid to keeping the pump clean and dry.
