Jinxiang Yun cooling ventilation equipment | suction fan Nanchang | Nanchang FRP suction fan | curtain Nanchang | Nanchang Pad | Nanchang home chiller | Nanchang chiller | Jiangxi suction fan | Jiangxi home air cooler | cooling fan, Jiangxi, Nanchang gold clouds in Nanchang plant cooling ventilation equipment industry enjoyed a high reputation, has many years of industry experience, pressurized turbine prices, customers can provide satisfactory products and professional services. The main cause of the fan rattling has these, as follows: (1) The fan shaft and motor shaft is not concentric; (2) based on the stiffness of the overall stent or inadequate; (3) bolts, rivets loose, or the impeller deformed; with the impeller shaft and the shaft hole between the plate (4) loosening; (5) there is dust or dirt on the blade or worn or deformed, so that the rotor becomes unbalanced; (6) Fan inlet and outlet piping is not installed, the resonance phenomenon occurs; (7) of the bearing temperature is too high, Jiujiang fan prices, or bearing box severe vibration occurs; (8) the quality of grease, but off, or interspersed with impurities, or deterioration up; (9) Rolling friction occurs between the inner and outer rings, or curved, damage; (10) or the inlet housing and the impeller friction; (11) the motor current is too large, or the temperature is too high; (12 ) When the fan starts, adjust the inner door or gate outlet piping is not closed tightly; (13) motor input voltage is too low, a power single-phase power outage; (14) transport medium temperature is too low, so that the motor is overloaded; (15) The system can not match the fan system performance, so that the fan is at a low pressure flow area, can not run well.

Notes centrifugal fan selection when (1) should be based on some of the key parameters to choose centrifugal fan, including aspects of the nature of gas transportation, the fan uses. (2) in the selection, should take into account the leakage loss, the calculation error and other aspects in addition to its safety factor should be taken into account, the amount of wind is 01.05-1.1, pressure to 1.1-1.15 for the best, so the fan will not damage. (3) pipe network resistance characteristic and centrifugal fan characteristic matching degree is also very important and should be able to allow the fan to stabilize the operation. General efficiency of its design case, should not be less than 90% of maximum air efficiency. (4) Select the fan should carefully compare prices small wind turbines, and to consider the long-term effects of the economy, rather than a one-time investment. (5) If you use more wind turbines, you should choose the same model. 2. centrifugal fan maintenance (1) 2,000 hours of operation a. Remove surface dirt, for bearings, bolts, inlet and outlet, couplings, belt to be checked, whether the issue. b. for lubrication should be checked, lubricants and seals were replaced. (2) 8000 hours operation including the above, but also on the impeller shaft and parts to be checked, if the problem should be repaired, not replace.
