Working principle of Roots blower

Roots blower is a positive displacement fan, the delivered air volume is proportional to the number of revolutions. Each time the three blade impeller rotates, two impellers carry out suction and exhaust for three times. Compared with the two blade type, the gas pulsation is smaller, the vibration is smaller and the noise is lower. There is always a small gap between the impeller on the two shafts of the fan and the hole surface in the oval shell, between the end face of the impeller and the front and rear end cover of the fan, and between the fan impeller. Driven by the synchronous gear, the wind is transported from the air inlet of the fan along the inner wall of the shell to the discharge side. Fan cavity does not need lubricating oil, simple structure, smooth operation, stable performance, adapt to a variety of uses, has been used in a wide range of fields.

Features of Roots blower

Energy saving, high precision, low noise, long service life, compact structure, small size, light weight, easy to use, the products are widely used in petrochemical, building materials, electric power, smelting, chemical fertilizer, mining, port, textile, food, paper making, aquaculture and sewage treatment, environmental protection industry and many other fields. Most of them are used to transport air, and can also be used to transport gas, hydrogen, acetylene, etc Carbon dioxide and other flammable, explosive and corrosive gases.

Characteristics of Roots blower

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

The impeller and shaft are of integral structure, and the impeller has no wear and tear. The performance of the fan remains unchanged and can operate continuously for a long time.

The fan volume utilization rate is large, the volume efficiency is high, and the structure is compact, the installation method is flexible and changeable. The selection of bearings is more reasonable, the service life of each bearing is even, thus prolonging the life of the fan!
