Operation and use of heavy duty centrifugal fans

(1) After the test operation of the heavy duty centrifugal fans is qualified, the surface of the heavy duty centrifugal fans shell should be wrapped with a heat insulation layer and the use of insulation materials, so as to reduce the heat transmission outside the shell and protect the safety of the bearing. Moreover, the thickness of the insulation layer should be well controlled, and it should also be convenient for maintenance and disassembly.

(2) The oil supply, vibration and temperature of the bearing should be checked frequently, so that the fan can operate normally.

(3) When the large centrifugal fan has just begun to work, the vibration of the bearing part is very small, but with the increase of the use time, the vibration will gradually increase. Once the maximum limit of the fan is reached, it is necessary to stop the machine for repair. Otherwise, if you continue to use it, there will be problems, hazards, and damage to the fan.

2. Stop the heavy duty centrifugal fans

(1) Normal parking

The normal stopping operation of the heavy duty centrifugal fans is as follows: first cut off its heat source, then reduce the speed of the heavy duty centrifugal fans to the minimum, let it slow down, until the temperature of the casing drops to normal temperature, and then stop the main motor.

(2) Accidental parking

That is, there is an emergency and the unit has to stop unexpectedly. At this time, the unit is in a hot state and the car should be manually turned on until the temperature of the casing drops below normal temperature.
