Roots blower structure: Rotor: the shaft, impeller, bearings, timing gears, couplings, bushings and other components. Impeller: Selection involute surface, high capacity utilization. Bearings: Close coupling end 3000 as the choice of locating double row spherical roller bearings. Near gear end as a free end selection 32000 type single row radial short cylindrical roller bearings to accommodate axial displacement of the rotor heat distention. Synchronous gear: the ring gear and the hub composition, easy to adjust the impeller clearance. ◆ host shell blower Roots blower housing, base, wall panels, fuel tank, rotor, gray cast iron HT250 manufactured by using resin sand casting, aging treatment. Surface design of the rib-like projections, not only played at a high temperature deformation is not easy pneumatic conveying blower, cooling surface and increase the surface area of ??the fan, the blower case design temperature of 160 ℃. Interface machining dust blower to smooth, to ensure airtight assembly. ◆ clover Roots blower rotor made of gray cast iron HT250 manufactured rotor leaf type line arc line. Taiwan uses four-axis CNC machining center with movable, once forming, high precision. Rotor balancing rigorous accuracy of G2.5 level, so that the exhaust air flow quite smoothly continuous, and shrink fit secured to transport the particles on the blower shaft, rotor during operation without touching the friction between the two, no seal and lubrication. Rotating blades static balance and dynamic balance in line with VDI 2060 Q-6,3, ISO1940 and ANSI S2.19 G2.5 standards.
