Part of the blower bearings: Near coupling end 3000 as the choice of locating double row spherical roller bearings. Near the end as a free end gear selection 32000 type single row radial cylindrical roller bearings. Transmission: Direct to the main coupling. If the performance specifications required, can also be used sheave shift the way. Couplings couplings aeration blower, can ease the impact and the compensation amount of axis deviation. Divided by the large flow fan motor as the driving machine, but also can be used turbine or other driver. Rotor: the shaft, impeller, bearings, timing gears, couplings, bushings and other components. Roots blower advantages: (1) between the blower rotor and the rotor, the rotor and the housing to retain a gap between 0.2-0.5mm aeration blower, there is no friction phenomenon Roots blower, allowing gas stream comprising some dust; (2) compared with the water jet blower and water ring vacuum pump, not "exhaust with water" problems; (3) Roots blower reliable operation, easy maintenance and durability.
