Characteristics of Roots blower
2020-07-08
Summary
Roots blower is a volumetric fan, the air volume delivered is proportional to the number of revolutions, and the three-blade impeller is sucked and exhausted 3 times by 2 impellers every time it rotates. Compared with the two-blade type, the gas pulsation is small, the vibration is small, and the noise is low. The impeller on the two shafts of the fan and the inner hole surface of the oval shell, the end surface of the impeller and the front and rear end covers of the fan and the impeller of the fan always maintain a small gap. Driven by the synchronous gear, the downwind 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, stable operation, stable performance, adapt to a variety of purposes, has been used in a wide range of fields.
Characteristics of Roots blower
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 selection of bearings is more reasonable, and the service life of each bearing is uniform, thereby extending the life of the fan!
The fan oil seal is made of imported fluorine rubber material, which has high temperature resistance, wear resistance and long service life.
The machine is complete and can meet the needs of different users for different purposes.
