Common type blower features: 1, casting resin sand casting process, by the Shandong Light Industry Machinery Factory foundry production, sixteen fan casting quality fully guaranteed. 2, in strict accordance with involute impeller design theory and simulation on a computer to do many times before installed rotational equilibrium experiments clover Roots blower, and fully guarantee the involute meshing characteristics Roots blower, effectively reducing the leakage and improve efficiency. Roots blowers can be roughly divided according to different single-stage and two-stage model of the sub-blower way it works, of which only one compression stage blower purchase Roots blower, which we call single-stage blowers, and the two single stage blowers together, for two consecutive compressed gas blowers we call the two-stage blower. Divided by Transmission: direct connection with fans and blowers Union; divided by Cooling: air cooling fans, blowers and water-cooled counterflow cooling blowers; by structure type: Vertical blowers, blower horizontal, vertical shaft blowers, densely into blowers and other groups; press seal type points: labyrinth seals, piston ring seals, packing and mechanical seals and other various types of blowers.
