Basic principle of Roots blower for sewage aeration:

Roots blower is widely used in sewage treatment aeration equipment. This article gives a detailed introduction from principle to use and maintenance!

Basic principle of Roots blower

Roots blower is a volume rotary blower.

① The compressor keeps the two rotors engaged by the synchronous gear at the rotor shaft end.

② Each concave curved surface on the rotor forms a working volume with the inner wall of the cylinder. During the rotation of the rotor, the gas is taken away from the suction port. When it is moved to the exhaust port,

③ Due to the backflow of gas with higher pressure, the pressure in the working volume suddenly rises, and then the gas is delivered to the exhaust channel. The two rotors do not contact each other,

④ They are sealed by tightly controlled clearance, so the discharged gas is not polluted by lubricating oil.

The above is the basic principle of Roots blower for sewage aeration. I hope it can help you!
