Roots blower is a volumetric fan with impeller end face and front and rear cover. The principle is a rotary compressor that uses two lobed rotors to move relative to each other in the cylinder to compress and transport gas. This kind of blower has simple structure and convenient manufacture. It is widely used in aquaculture aeration, sewage treatment aeration, cement transportation. It is more suitable for gas transportation and pressurization systems in low-pressure occasions, and can also be used as a vacuum pump.

Roots blower consists of five parts: casing, wall panel, impeller, fuel tank and muffler.

Casing: mainly plays the role of support (wall panel, impeller, muffler) and fixation.

Wall plate: mainly used to connect the casing and the impeller, and support the rotation of the impeller, as well as the effect of the end face seal.

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

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

Muffler: used to reduce the noise generated by the airflow pulsation when the roots blower enters and exits.

Features:

Due to the use of three-blade rotor structure and reasonable structure at the inlet and outlet in the shell, the fan has small vibration and low noise.

Impeller and shaft for the whole structure and the impeller without wear, fan performance lasting, can be long-term continuous operation.

The fan volume utilization rate is large, the volume efficiency is high, and the structure is compact, and the installation method is flexible and changeable.

The machine is complete and can meet the needs of different users for different purposes.
