Let me introduce you: Where is the difference between Roots vacuum pump and screw vacuum pump?

Roots vacuum pump and screw vacuum pump are one of the universal vacuum pumps, each has a different working principle and scope of use, the following is a simple comparison:

1. Different working principles: Roots vacuum pump uses two synchronous rotating Roots impellers to achieve gas suction and discharge, producing gas flow to achieve the purpose of vacuum. The screw vacuum pump realizes the gas suction through two meshing screws, and also uses the movement of the screw to produce gas flow.

2. The operation efficiency is different: because of the simple structure of Roots vacuum pump, the diameter and length of the flow channel are relatively large, so it can achieve high speed and large flow vacuum pump. Due to the shape of the screw, the screw vacuum pump is suitable for occasions where high vacuum and relatively low flow are required.

3. Different application scenarios: Roots vacuum pump is suitable for a wide range of pressure occasions, can be used in manufacturing, environmental engineering, water treatment and food industry and other fields. The screw vacuum pump because of its high vacuum, suitable for chemistry, electronics, optoelectronics and aerospace and other high-precision requirements of the field.

In short, the two kinds of vacuum pumps have their own advantages and application occasions, the specific choice of vacuum pumps also need to be considered according to the use requirements and specific application fields.
