RB-022 works when pressure blower fan impeller rotates, the centrifugal force, the vane to move outwardly to promote gas, thereby forming a series of spiral movement. Air between the impeller blades rotating spiral accelerated and squeeze the gas pump outside the side grooves, when it enters the side channel two later, the gas is compressed, and then again between the impeller blades spin up. When the air along a spiral track through the impeller and the lateral grooves, each of the impeller blades increases the degree of compression and speed, with the rotation proceeds, the gas kinetic energy increases, so that the side channel along by the gas pressure further increases. When the air reaches the side of the tank and the discharge flange connection point, the gas incurs extruded blades and through the outlet. RB-022 fan features: a high-pressure, high winds, low noise and lightweight. 2 fan with aluminum alloy material, significantly reducing weight to achieve the purpose of lightening. 3 IEC Designed motor (1HP above), totally-enclosed fan-shaped aluminum frame motor, special shaft design may be suitable for prolonged use. 4 special fan blade design, high pressure, air volume, low noise, long life 5. Blower special air volume control damper, air volume control and high stability, easy operation. 6 fans range styles inventory, fast delivery. RB-022 wind turbine maintenance 1. Complete product information booklets, all borrowed materials, supplies, performance, operating range and other ranges were filing out books. (2) using oil-bath Pillow Block Bearings, closed sump, bearings and shaft protection against acid erosion of alkaline gases, long life, low failure rate. 3 to provide fans with maintenance manual for each maintenance work there are certain procedures, maintenance records, but also to record and retain for easy transition. 4 modular production, unified specifications, spare parts supplies full list can be in the fastest time, at least cost to complete the repair. 5 user-friendly design of the bearing box, easy to change the oil, easy to measure vibration. 6 chassis configuration manholes, cleaning impeller fouling hassle-free viewing.
