A few tips for using a centrifugal fan correctly
Even if you buy a centrifugal fan of a well-known brand, if the user does not strictly follow the instructions in use, it will reduce the use of the fan and even shorten the service life of the centrifugal fan. This is also a big problem for the user. The loss of the correct use of the centrifugal fan not only guarantees its use, but also greatly extends the service life of the fan. Therefore, many users want to know exactly what kind of use is the most correct. The damage is minimized? Today we will 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 first use of a centrifugal fan is from its start. 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 and 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 most common problem with centrifugal fans is the vibration of the fan. It is not a simple matter to solve this problem fundamentally, but it is a very good solution to reduce the fan speed, and this method is the most effective. 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.
