What we need to do is to press the centrifugal fan to keep the airway unblocked in operation. The power of the centrifugal fan will be overloaded when the air volume is very small. We should pay attention not to use the centrifugal fan for a long time in the sealed and insufficient air supply environment or when the valve is completely closed. In the best case, the current should be monitored regularly. 2. Before the centrifugal fan is used, it is necessary to test the fan. This process is to ensure that the fan runs without fault, so that the effectiveness of the fan can be guaranteed to the greatest extent.
3. If the fan has not been used for a long time and is reused, we must first check whether the various components of the fan are still solid. Once we find any looseness, we must tighten it in time. In this way, when the fan is in trial operation, the fan will not be used normally because of the loosening of the fan components.
4. Before starting the fan, it is necessary to inspect the centrifugal fan and the articles in the pipeline that hinder rotation. If so, it should be cleared before starting.
5. Fans should be put into use cautiously after debugging has not found any problems, and every reflection of centrifugal fans should be observed regularly. Once abnormalities are found, they should be stopped immediately for inspection.
