　　The use of centrifugal fans

　　Nowadays, high-speed centrifugal fans are widely used in both civil and industrial applications. For the majority of users, correct and reasonable operation and use of centrifugal fans can reduce the failure rate and extend the service life. At the same time, it can also ensure that the centrifugal fan maintains a normal operating state for a long time, creating more considerable economic benefits. Therefore, the centrifugal fan operator must have the correct operating skills. In order to repay the support of users over the years, centrifugal fan manufacturers will summarize and explain the use skills of centrifugal fans.

　　When starting the centrifugal fan, if the starting failure or the starting time is too long, there are many reasons. 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 when starting, verify when starting When the gas flow control mechanism is in the closed position.

　　If the rotor is stuck, turn the fan by hand to check and investigate the cause of the stuck (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 power cable. In addition, if you use a centrifugal fan, one of the common problems is fan vibration. To solve this problem fundamentally, you can reduce the fan speed.

　　Although the faults can be reduced by operating the centrifugal fan correctly, it does not mean that no faults will occur. If the centrifugal fan fails, you don't have to worry too much. As long as you can find out the cause of the failure and adopt corresponding methods, you can quickly and effectively resolve the failure and restore the centrifugal fan to normal operation.
