2. Fan the common causes of failure analysis generated a lot of fan vibration, low noise centrifugal wind chassis Anqing, checks can be carried out from the following areas: A, impeller and duct with friction, Mingguang centrifugal wind chassis, and abnormal sound and vibration; B, stand foot bolt not tightened, large vibration will occur; C, the impeller due to the transport of compressive deformation or loose bolts and vibration; D, blade and shaft sleeve attachment screws loose or bending E, stand Loose screws result in connection with the motor blades unbalanced, bearing damage caused by intense vibrations. 3, fever. Under normal operation for some time, found that the motor temperature is too high, you may have the following causes: A, motor bearing damage, with the gap is small, does not meet the requirements; B, the shaft and the bearing mounting skew, Anqing centrifugal wind chassis specifications, two bearing misalignment; C, the resistance is too large, the motor overload operation; D, the power supply voltage is too low or the three-phase motor-off phase operation. Product Details Price: 1 yuan minimum purchase quantity: 1 Product details HTFC wind chassis HTFC HTFC wind chassis series Wind chassis, one machine, high efficiency, low noise vibration filial piety, having a novel structure, light weight, ease of installation ( floor installation, lifting may be), it is widely used in hotels, halls, theaters, underground parking tasted industrial enterprises and other needs ventilation, fire smoke in the workplace.
