The first FRP centrifugal fan, for maintenance and repair a broken main power, check the electrical grounding of the motor is good. 2 fastening screws and various parts of the coupling. 3 detects the motor insulation resistance is compliant, check the main circuit contacts. If the contacts severe erosion (wear contact point to the original thickness of 1/3), replace the contacts. Note: when maintenance should be hung in the power of positive pressure blower sign informing people being repaired second valve for maintenance: 1 to adjust the tightness of the belt, the hand plate moving wind turbine industrial heaters, observe the rotation is stable . 2 Check and replace gaskets and packing joints between each. 3 Clean the motor and wind wheel, filters and internal chassis. Department should make up for peeling paint brush. 4 to fill lubricating moving parts, in order to ensure the flexibility and stability of the coupling and the third bearing, electrical circuit repair and maintenance: a check valve mechanical opening and closing action is reliable, flexible, opening and closing angles are clearly marked . Two lights and a manual start checking voltage, current meter is working properly, the fan running all components have same sound, three-phase current imbalance. 3-point comprehensive inspection of each remote control box components are normal. 4 three consecutive open stands, remote check points are correct and reliable. 5 commissioning two hours, observing motor bearing temperature, motor temperature is normal. Make sure the fan is operating normally. For suction fan should be every six months for regular maintenance, and record, ensure good operation of the suction fan. Fans routine maintenance and troubleshooting methods, whether any of the products, using the process requires care and maintenance in order to increase the life of the product and is not easy to fail. Daily suction fan maintenance needs to do the following: 1. Regularly check the fan motor, frame and other parts of the screws are loose 2. Regularly check the fan blade screws are loose 3. Check the fan motor is running well, it has slowed down, there are No buffer start, excessive noise and other phenomena has 4. Check the fan control switch is stable, maintain a good line 5. Check whether the voltage stability and maintaining good lines 6.
