Structure of Roots blower
- Roots blower consists of five parts: casing, wall board, impeller, oil tank and muffler.
- Casing: mainly plays the role of supporting (wall boards, impellers, mufflers) and fixing.
- casing
- Wall board: mainly used to connect the casing and impeller, support the rotation of the impeller, and provide end-face sealing.
- Impeller: It is the rotating part of the Roots blower, divided into two blades and three blades. However, due to the many advantages of three blades, such as smaller air pulsation, lower noise, and smoother operation than two blades, it has gradually replaced the two-blade Roots blower.
- impeller
- Oil tank: Mainly used to store lubricating oil used to lubricate gears and bearings.
- Oil tank
- Muffler: used to reduce the noise caused by air flow pulsation when the Roots blower enters and exits.

How does a Roots blower work?
- root blower working principle
- 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.
