Installation should carefully check whether the blades and housing due to shipping damage or deformation, or should be repaired before installation. 2. Check for loose bolts, Fuyang, Huainan positive pressure blower fan before the start, you should first check within Shaanxi two-speed exhaust fan duct interfere with or without rotation of items. 3. Check the motor insulation performance is good, after turning on the power to check friction collision and abnormal vibration. The reason a lot of fan vibration, Shandong Asia-Pacific two-speed exhaust fan to be checked from the following aspects: a, impeller and duct with friction Fuyang, Huainan positive pressure blower, and audible and vibration abnormality; b, bracket feet Bolt is not strong, large vibration will occur; connecting bolts c, impeller and sleeve loose; d, bracket and motor connection loose bolts cause impeller unbalance, bearing damage caused by excessive vibration. 5. Under normal operation found that the motor temperature is too high, Shaanxi two-speed exhaust fan may be caused by the following reasons: a, motor bearing damage, with the gap is small, does not meet the requirements; b, the shaft and the bearing mounting tilt, two bearing different axes; c, three-phase power supply voltage is too low or run-off phase. 6. The exhaust port in Shandong Pacific two-speed exhaust fan interlock device should be located in Fuyang, Huainan positive pressure blower, when any one of the exhaust port open, exhaust fan that is able to automatically start.
