Correct use of industrial centrifugal fans

The industrial centrifugal fan can be used according to the operation method in use, which will also reduce the use effect of the fan and even shorten the service life of the centrifugal fan. This is also a great loss for the user, and the correct use of the centrifugal The fan not only guarantees its use effect, but also prolongs the service life of the fan to a large extent. Therefore, many users want to know exactly what kind of use is correct, can the damage to the fan be reduced to low? Today Let's introduce some tips for using centrifugal fans. I believe that as long as the user masters these, it will definitely improve the efficiency of the fan to a certain extent.


The use of industrial centrifugal fans begins with its start-up. Sometimes there are problems with startup failures or very long startup times. There are many reasons for this. If the motor does not move, check the set value of the safety mechanism; if the motor rated power is too low, replace the motor; if the starting procedure is not correct, adjust the starting equipment; if the power consumption is too large when starting, verify that when starting When the gas flow control mechanism is in the closed position; if the rotor is stuck, move the fan by hand to check and investigate the cause of the jam (friction, obstacles, etc.); if the voltage at the motor is too low, Check the power line voltage - if the loss is too large, increase the power line.

Many times users will find that the impeller always consumes energy in vain. The gas forms a recurrent activity through leakage between the front cover and the current collector. Maintain a certain gap between the front cover of the centrifugal fan and the current collector and between the casing and the shaft. To ensure the reliability of the fan rotation. This can greatly alleviate this phenomenon.

The problem with the use of industrial centrifugal fans is the vibration of the fan. It is not a simple matter to solve this problem fundamentally, but if the fan speed is reduced, it is a very good method, and the effect of this method is also significant. . However, it is also necessary for the user to judge what method is used to be more reasonable according to the specific conditions of the fan used.
