How to better use centrifugal fans

The use of a centrifugal fan starts from its start. Sometimes there may be startup failures or longer startup times, and there are many reasons for this situation. If the motor cannot be dragged, check that the safety is the set value of the mechanism; If the rated power of the motor is too low, replace the motor; If the starting program is incorrect, adjust the starting equipment; If the power consumption is too high during startup, verify whether the gas flow control mechanism is in the closed position during startup; If the rotor gets stuck, manually rotate the fan to check and investigate the cause of the blockage (friction, obstacles, etc.); If the voltage at the connection of the motor is too low, check the voltage of the power line - if the loss is too large, increase the power line.
Many times, users will find that the impeller is always consuming energy in vain. The leakage of gas between the front cover and the collector forms cyclic activity. The clearance that needs to be maintained is between the front cover of the centrifugal fan and the collector, and between the casing and the shaft. Reliable fan rotation. This can greatly alleviate this phenomenon.
The common problem with centrifugal fans in use is the vibration of the fan. It is not a simple task to fundamentally solve this problem, but reducing the fan speed is a good solution, and the conclusion of this method is also significant. However, users still need to determine what method to use based on the specific situation of the fan they are using in order to be more reasonable.
