Working Principle of Air Blower

The air blower is mainly composed of the following six parts: motor, air filter, air blower body, air chamber, base (and oil tank), oil dripping nozzle. The air blower operates by the eccentric rotor in the cylinder, and makes the volume change between the blades in the rotor slot to absorb, compress and eject the air. During the operation, the pressure difference of the air blower is used to automatically send the lubrication to the oil dripping nozzle and drop it into the cylinder to reduce the friction and noise, while keeping the gas in the cylinder from returning. Air blowers are mainly divided into roots air blower, centrifugal air blower and rotary air blower. The working principles of different types of air blowers are different.
