How does a Roots style blower work?

• The working principle of Roots blower can be simply summarized into the following steps:
• 1.Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
• 2.Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
• 3.Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
• By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

Root vacuum pump working principle

• The working principle of the Root vacuum pump is to use a pair of blade-shaped rotors to synchronously and counter-rotate in the pump chamber, sucking the gas from the air inlet, compressing it and expelling it through the exhaust port to achieve the air extraction function. ‌
• The characteristic of this kind of pump is that there is a certain gap between the rotors and between the rotors and the inner wall of the pump casing, allowing high-speed operation.
• Roots vacuum pump is a kind of vacuum pump without internal compression. Usually the compression ratio is very low, so it needs to be used in conjunction with a backing pump to achieve efficient pumping.
• This kind of pump is widely used in the fields of petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balancing, aerospace space simulation and other fields. It is favored because of its fast start-up, low power consumption, low operation and maintenance costs and other characteristics. favor. ‌

What is a roots type vacuum pump?

• Roots vacuum pump is a high-performance vacuum equipment that uses the mutual meshing of Roots impellers (or double Roots impellers) to achieve the purpose of air suction and exhaust.
• The principle is as follows: when the Roots impeller rotates, the gas forms a vacuum between the impellers due to the small gap between the impellers.
• At the same time, the gas at the air inlet of the vacuum pump is compressed. After the rotation of the impeller, the gas is sequentially transported and gradually expanded to achieve the purpose of exhausting.
