How to use centrifugal fan correctly

Even if the user can choose a good centrifugal fan, but 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 great loss to the user. The correct use of centrifugal fan can not only ensure its use effect, but also to a large extent extend Long service life of the fan, so many users want to know what is the right use, in order to reduce the damage to the fan? Today we will introduce some tips for using centrifugal fan. It is believed that as long as users master these, the efficiency of fan can be improved to a certain extent.
The use of centrifugal fan starts from its start-up. Sometimes there will be startup failure or start-up time is very long. There are many reasons for this. If the motor can not be dragged, 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 not correct, adjust the starting equipment; if the power consumption is too large, verify whether the gas flow control mechanism is in the off position when starting; If the rotor is stuck, manually turn the fan to check and investigate the cause of the seizure (friction, obstacles, etc.); if the voltage at the motor wiring is too low, check the power line voltage - if the loss is too large, increase the power line.
Most of the time, users will find that the impeller is always consuming energy in vain. The gas circulates through the leakage between the front cover and the collector. A certain clearance must be maintained between the front cover of centrifugal fan and the collector, and between the casing and the shaft. To ensure the reliability of fan rotation. This can alleviate this phenomenon to a great extent.
Centrifugal fan in the use of the most common problem is the vibration of the fan, want to fundamentally solve this problem is not a simple thing, but if you reduce the speed of the fan is a very good way, and the effect of this method is also the most significant. However, users need to judge what method to use according to the specific situation of the fan to be more reasonable.
