As an important mechanical equipment, centrifugal fans play a key role in fields such as industrial production. However, in the process of its use, some problems are often encountered.

First of all, the start-up problem of centrifugal fans cannot be ignored. Sometimes there will be start-up failure or a very long start-up time. There are various reasons for this. If the motor cannot pull, check the setting value of the safety mechanism; if the rated power of the motor is too low, replace the motor; if the starting procedure is incorrect, adjust the starting equipment; if the power consumption is too large when starting, verify whether the gas flow control mechanism is in the closed position when starting; if the rotor is stuck, manually rotate the fan to check and investigate the cause of the jam (friction, obstacles, etc.); if the voltage at the wiring point of the motor is too low, check the power line voltage. If the loss is too large, increase the power line.

Secondly, many users will find that the impeller is often consuming energy in vain. This is because the gas forms a circulating activity through the leakage between the front cover and the collector. In order to ensure the reliability of the fan rotation, a certain gap must be maintained between the front cover and the collector of the centrifugal ventilator and between the casing and the rotating shaft. This can largely alleviate the phenomenon of energy waste of the impeller.

Finally, the most common problem in the use of centrifugal fans is the vibration of the fan. Solving this problem fundamentally is not an easy task. Reducing the speed of the fan is a method with remarkable effects, but this requires users to judge which method is more reasonable according to the specific situation of the fan in use.

In short, understanding the common problems in the use of centrifugal fans and adopting corresponding solutions is crucial for ensuring the normal operation of centrifugal fans and improving their working efficiency.
