TIPS

How to use the centrifugal fan correctly  
   Even if the user can choose a good one when choosing a centrifugal fan, if the user does not strictly follow the instructions in use, it will reduce the use effect of the fan and even shorten the service life of the centrifugal fan, which is also a problem for the user. This is a huge loss. The correct use of the centrifugal fan can not only ensure its use effect, but also prolong the service life of the fan to a large extent. Therefore, many users want to know what is the correct use to use What about reduced damage to the fan? Today we will introduce some tips for using centrifugal fans. I believe that as long as the user masters these, the efficiency of the fan can be improved to a certain extent.

        The use of the centrifugal fan starts from its start-up. Sometimes there will be a problem of startup failure or very long startup time. There are many reasons for this situation. If the motor does not drag, check the setting of the safety mechanism; if the rated power of the motor is too low, replace the motor; if the starting procedure is not correct, adjust the starting equipment; if the power consumption when starting is too large, verify that the starting Check whether the gas flow control mechanism is in the closed position when the rotor is stuck; if the rotor is stuck, turn the fan by hand to check and investigate the cause of the jam (friction, obstruction, etc.); if the voltage at the motor wiring is too low, the Check power cord voltage - if loss is excessive, increase power cord.

        Many times users will find that the impeller is always consuming energy in vain. The gas circulates through the leakage between the front cover and the current collector. A certain gap must be maintained, between the front cover of the centrifugal fan and the collector and between the casing and the rotating shaft. To ensure the reliability of fan rotation. This can alleviate this phenomenon to a great extent.

        The problem that often occurs in the use of centrifugal fans is the vibration of the fan. It is not a simple matter to fundamentally solve this problem, but it is a very good way to reduce the speed of the fan, and the effect of this method is also very obvious. on. However, it is still necessary for the user to judge which method to use according to the specific situation of the fan used to be more reasonable.
