Host by cast iron rotary fan casting, metal ring 2 (or spring 8), host a shaft, a rotor, slide 4, an eccentric cylinder, pump cover consisting of two rotary blower outlets, among fans metal ring rotor vane pump cover and eccentric cylinder manufacturing rotary blower by wear-resistant castings, the host axis by 45 # steel manufacturing. rotary vane blower 4 equal portions embedded in rotor rotary blower fastened to the center of the rotor shaft, the shaft with bearings at both ends of the front and rear pump cover mounted on an eccentric connected to the cylinder, this time is embedded in the rotor and the vane rotor inner wall of cylinder 4 is formed with four volumes ranging space, turning the rotary blower fan wholesale phone during operation, the metal ring or spring slide along the cylinder wall to promote uniform motion, rotary blower block by suction, suction port guide gas tank, exhaust, exhaust inlet gas guide groove formed a working process rotary fan by: intake stroke, compression stroke rotary fan uses three parts exhaust stroke when the rotary fan rotation of the rotor vane groove 4 reciprocate. The air is sucked into, compressed, is discharged to form the fan. Rotary fan notable design features eccentric rotation of the rotor in the cylinder, oil-lubricated, low-speed, air flow range: 0.31 m3 to 5.41 m3 per minute per minute, the pressure range: 9.8 kPa to 49 kPa varactor compression low-noise blowers called rotary fan. 1. Small, air volume, low noise, energy province. 2. smooth operation, easy installation. 3. Anti-load change, stable air volume. 4. with air chamber, stable bulk gas.
