Faults often occur in the opening of regenerative blower, which affects the function of fan. Have you found the cause of the fan failure?
When the high-pressure fan can not start, please confirm the power supply immediately. Check the fans one by one and determine the parameters. If the configuration is unreasonable, it needs to be adjusted.
Then check whether the starting capacitor is in good condition and see if the capacitor is invalid. Because there is insufficient electricity in many expired capacitors, electricity can be used. At the same time, ensure that there is a lot of dust in the fan. There is a lot of dust in the air. The dust content of GE in the process of fan operation affects the long-term corrosion of blade rings, and the balance of blade rings, joints and joints of fan is liable to collapse. Therefore, bearing wear is serious, high-pressure fan can be greatly reduced, fan can not operate normally.
You also need to check whether the fan motor is damaged. Many users do not notice the direction of the fan when installing the motor. Errors occurred during installation. Failed to start the fan.
