Centrifugal fan cleaning disassembly and assembly requirements! 

 After the centrifugal fan operates in the environment for a period of time, a layer of dirt will accumulate in each gap or on the surface of the parts. In order not to affect the normal use of the centrifugal fan, it is necessary to remove the casing and bearing box of the fan for thorough cleaning. If the two parts of the centrifugal fan are not removed first, the overall cleaning of the whole fan can not be completed; Secondly, what we need to pay special attention to in the process of cleaning is that we can not disassemble and clean the motor directly connected to the fan part, in order to prevent the mechanical failure of motor burning. After the complete cleaning of the centrifugal fan, the parts should be assembled. First, a pair of inclined pads are used to flat the iron pad and placed on the foundation. Secondly, whether it is cleaning or assembling the centrifugal fan, the regulating mechanism is tested first to check its rotation flexibility. It can be seen that when disassembling and assembling centrifugal fans, we should start from those key points. Only by paying attention to these key points can we ensure the accuracy of the actual disassembly work, and reduce the possibility of problems during assembly after the completion of cleaning work, so as to ensure that users can use the fans normally and ensure that the production work is not affected. In addition, we can not ignore the selection of centrifugal fans. For the ventilation system with noise requirements, we should first choose the centrifugal fan with high efficiency and low impeller circumference velocity, and make it work at the high efficiency point. In addition, corresponding measures should be taken to reduce noise and vibration according to the propagation mode of noise and vibration produced by ventilation system.
