What is the working principle of Roots blower?

What is the working principle of Roots blower? Widely used in aquaculture oxygenation, sewage treatment aeration, cement transportation, more suitable for low pressure occasions of gas transmission and pressurization system, can also be used as a vacuum pump.

The principle is a rotary compressor that uses two blade rotors to make relative movement in the cylinder to compress and transport gas. The blower is simple in structure and easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transmission, and more suitable for gas transmission and pressurization systems in low pressure occasions, and can also be used as a vacuum pump.

Roots blower is composed of five parts: casing, wallboard, impeller, oil tank and muffler.

Casing: mainly used for supporting (wallboard, impeller, muffler) and fixing.

Wall plate: mainly used to connect the casing and the impeller, support the rotation of the impeller, and play the role of end sealing.

Impeller: it is the rotating part of Roots blower, which is divided into two leaves and three leaves. However, due to the advantages of three leaves, such as less air pulsation, less noise, and more stable operation than two leaves, it has gradually replaced the two leaves Roots blower.

Oil tank: mainly used to store lubricating oil used to lubricate gears and bearings.

Muffler: It is used to reduce the noise caused by air flow pulsation during the inlet and outlet of Roots blower.

characteristic

Due to the adoption of a three blade rotor structure and a reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is permanent and can operate continuously for a long time.

The fan has large volume utilization rate, high volume efficiency, compact structure and flexible installation mode. Complete models can meet the needs of different users for different purposes.
