Operating principle Rotary blower fan is biased against the inner cylinder rotor eccentric operation, and volume change blade rotor slots between the air intake, compression, spit. The blower pressure difference in the operation automatic lubrication to drip nozzle inner cylinder was dropped to reduce friction and noise while maintaining the cylinder of gas is not reflux. Rotary fan their maintenance knowledge 1, must be hand use, Chengdu rotary blower, hand repair. 2, allowed sick to run. 3, periodically clear the dust inside, rotating fan manufacturers wholesale, especially on the impeller dust, dirt and other impurities, in order to prevent corrosion and imbalances. 4, repairs must be emphasized first stop off. 5, a thermometer and regularly check the sensitivity of the subject of oil. Rotary Fan Features: 1, flow, pressure coverage, wide application range, high quality 2, the impeller type line using a special complex envelope line, has an engagement, less internal leakage, where good rotary fan, low temperature, efficiency High pressure fluctuation pulse, low noise. 3, because the rotor using a special appearance, enhances the rigidity of the shaft, improved rotary blower fan manufacturers boost wholesale, Chengdu rotary fan, Zhucheng East Machinery Co., Ltd. by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd.
