The same vacuum pump products, why is it divided into many kinds?Because of the different industry fields and the use of the environment, the different series and specifications of vacuum pumps will also be different.Although there is only a word difference between screw vacuum pump and Roots vacuum pump, there is a great difference in performance and application.The following is the analysis done by Jiangsu Quantianxia Intelligent Equipment Co., LTD., mainly from the performance characteristics, application scope, working principle to distinguish three points:

Different performance characteristics

Screw vacuum pump: compact and simple structure, no need for any working medium, no oil pollution, no sewage discharge, energy saving and emission reduction effect is significant.

Roots vacuum pump: fast start, less power consumption, low operation and maintenance costs, high pumping speed, high efficiency, and insensitive to a small amount of water vapor and dust contained in the pumped gas.

Different application range

Screw vacuum pumps are widely used in pharmaceutical, chemical, semiconductor and other fields with high requirements for clean vacuum.

Roots vacuum pump is widely used in vacuum metallurgy smelting, degassing, rolling, as well as chemical, food, pharmaceutical industry in vacuum distillation, vacuum concentration and vacuum drying and other aspects.

Different working principle

Screw vacuum pump is through two meshing screw to achieve gas suction and exhaust, but also use the movement of the screw to produce gas flow.

The Roots vacuum pump uses two synchronous rotating Roots impellers to realize gas suction and discharge, produce gas flow, and achieve the purpose of vacuum.

Therefore, in the choice of screw vacuum pump and other pump products, we must first understand their needs, do not think that from the literal life almost think that the use of the same, must be based on the specific use of the environment to choose the right type and specifications.
