Previous knowledge about centrifugal fans has also been talked about a lot. Today, we will explain the knowledge about the use and operation of large centrifugal fans. The main contents of this period are as follows: (1) After the large centrifugal fans are qualified for commissioning, they should be coated with insulation layer on the surface of the fan casing and use insulation materials in order to reduce the heat transfer from the casing to the outside. Sow, protect the safety of bearings. Moreover, the thickness of the insulation layer should be well controlled, and it should be easy to repair and disassemble.
(2) The oil supply, vibration and temperature of the bearing should be checked regularly so that the fan can operate normally.
(3) When a large centrifugal fan is just starting to work, the vibration of bearing parts is very small, but with the increase of service time, its vibration will gradually increase. Once the maximum limit of the fan is reached, it is necessary to shut down and repair it. Otherwise, if it continues to be used, there will be problems, dangers and damage to the fan.
