Because impeller is running in the body without friction, do not need lubrication,
Air blower
Air blower
The exhaust gas is not oily. Is chemical industry, food and other industrial ideal pneumatic conveying gas source.
The air blower belongs to the volumetric operation blower. When used, the flow varies greatly as the pressure changes. But the flow changes with the speed. Therefore, the selection of pressure is wide and the choice of flow can be achieved by selecting the speed.
The speed of the blower is relatively high, and the space between the rotor and rotor, the rotor and the body is small, thus leakage is less and the volume efficiency is higher.
The structure of the blower is determined that the mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact on the selection, the rotor, case and gear ring have sufficient mechanical strength. Safe operation, long service life is one of the characteristics of blower products.
The rotor of the fan blower is checked by static and dynamic balance. The finished product runs smoothly and vibrates very little.
The main types of blower are: roots blower, side flow fan, multi-stage centrifugal blower.
