Three-lobe Roots blower

 

principle :

  Three leaf roots blower is a kind of positive displacement fan. Its pressure can be adjusted within the allowable range according to the requirements of users. There are two groups of impellers rotating in opposite directions inside the casing, between impellers and impellers, and between impellers and shells

Only a small gap in the state of rotation. When the impeller passes through the suction end, a certain amount of air is captured between the impeller and the shell. With the rotation of the impeller, the air moves laterally, and the pressure increases gradually, and then it is sent to the outlet end.

characteristic

■ wide range of air volume and pressure.
Caliber: 32mm-400mm (1.25 "- 16")
Air volume: 0.38-283m 3 / min (13-9985cfm)
Pressure: one stage PRB can reach 8000mmaq (0.8kgfgcm2)

■ the exhaust gas is free of oil.

■ computer dynamic balance correction, low vibration and low noise.
The air volume is stable, and the pressure change has little influence on the air volume.
Special impeller design, high efficiency and energy saving.
The structure is simple, strong and trouble free.
The first grade grinding gear has high precision, long service life and low noise.
Strict quality management and standardized products.
The impeller is processed by a new six axis planer
It is convenient to replace and has higher precision.
