The main features of the Roots blower Roots blower biggest feature is the use when the pressure within the range of variation of the flow rate to be adjusted to allow minimal aeration blower, choose a wide range of pressures, has forced gas transmission characteristics. When the transmission medium is not oil. Simple structure, easy maintenance, long life, low vibration machine. Vacuum pumps. Because of the periodic suction, exhaust and compression caused by fluctuating instantaneous isometric flow velocity and pressure aeration blower, which will have a greater aerodynamic noise. In addition, the gap between the rotor and between the rotor and the cylinder will cause gas leakage, so that the efficiency is reduced. Roots blower displacement is 0.15 to 150 m3 / min Roots blower, rotation speed of 150 to 3000 r / min. Single-stage pressure ratio is typically less than 1.7 up to 2.1, you can use multi-level series. 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, can ease the impact and the amount of compensation 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.
