Introduce the different characteristics of Roots blower:

Roots blower is a positive displacement fan, and the air volume conveyed is proportional to the speed. Two impellers are used for three times of suction and exhaust for every revolution of the three blade impeller. Compared with the two blade type, the gas pulsation is small, the vibration is small, and the noise is low. Impellers on the two shafts of the fan and the inner hole surface of the elliptical housing.

There is always a small gap between the end face of the impeller and the front and rear end covers of the fan and between the impeller of the fan. It is transported from the air inlet of the fan along the inner wall of the housing to the discharge side at the downwind of the synchronous gear traction. The fan cavity does not need lubricating oil, has simple structure, stable operation, stable function, and is used to many purposes, and has been used in a wide range.

Roots blower is characterized by a three blade rotor structure and a reasonable air inlet structure in the box. The fan has low vibration, low noise, integral structure of impeller and shaft, and no impeller wear. The fan function is permanent and can work continuously for a long time.

The fan has large volume utilization rate, high volume efficiency, compact structure and flexible and diverse device modes. The bearing selection is reasonable, and the service life of each bearing is even, which extends the service life of the fan! The fan seal adopts imported fluororubber materials, which is high temperature resistant, wear-resistant, and has a long service life, and can meet the needs of different users for different purposes.
