Working principle of three-leaf roots blower

Compared with the two-leaf blower, the three-leaf Roots blower has less gas pulsation, less vibration and lower noise. Impellers on the two shafts of the fan always keep a small gap with the inner hole surface of the elliptical shell, between the end face of the impeller and the front and rear end covers of the fan, and between the impellers of the fan, and the downwind driven by the synchronous gear is transported from the inlet of the fan to the discharge side along the inner wall of the shell. The fan cavity does not need lubricating oil, with simple structure, stable operation and stable performance, which is suitable for various purposes and has been widely used in various fields.
