The first use of centrifugal fans began with its start-up. Sometimes there will be a start-up failure or start-up time is very long, there are many reasons for this situation. If the motor cannot 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 incorrect, adjust the starting equipment; if the power consumption is too large, check whether the gas flow control mechanism is in the closed position when starting; if the rotor is stuck, use the manual fan to check and investigate the stuck original. Because (friction, obstacles, etc.); if the voltage at the connection of the motor is too low, check the voltage of the power line, such as excessive loss, increase the power line.
Many times users will find that the impeller is always white energy consumption. The gas leaks between the front cover and the collector to form cyclic activity. There must be a certain gap between the front cover of the centrifugal ventilator 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 large extent.
The most common problem in the use of centrifugal fans is the vibration of fans. It is not a simple matter to solve this problem fundamentally, but if reducing the speed of fans is a very good method, and the effect of this method is most remarkable. However, users need to judge which method is more reasonable according to the specific conditions of the fans they use.
