What Matters Should Be Paid Attention To In Operation Of Centrifugal Fan

Centrifugal fan operation of some things to pay attention to, let's see what they need to pay attention to the specific matters.

Always pay attention to the temperature and lubrication and cooling of the bearing of centrifugal fan.

1. Pressure oil lubrication for rolling bearings: normal temperature of bearings should be less than 60 C, allowable 70 C, inlet oil temperature 35 C-45 C, outlet oil temperature 55 C-65 C, temperature rise less than 40 C.

2. Oil lubrication of rolling bearings: normal temperature of bearings should be less than 70 C, allowable 80 C, inlet oil temperature 35 C-45 C, outlet oil temperature 55 C-65 C, temperature rise less than 40 C.

3. Sliding bearing: bearing normal temperature should be less than 70 C, allowable 80 C, inlet oil temperature 35 C-45 C, outlet oil temperature 55 C-65 C, temperature rise less than 40 C.

3. Sliding bearing: The normal temperature of bearing should be less than 65 degrees C, 70 degrees C allowed, the inlet oil temperature should be 35 degrees C-45 degrees C, the outlet oil temperature should be 55 degrees C-65 degrees C, and the temperature rise should be less than 35 degrees C.


Pay attention to the vibration and impact noise of the unit. It is necessary to check the amplitude of the bearing seat with a vibration meter. Listen for collisions and other sounds inside the machine.


Monitor the motor load with ammeter. Centrifugal fans are not allowed to operate for a long time under stir-frying load.


For centrifugal fans such as dust exhaust and pulverized coal, it is necessary to check whether the changes of dust and ash particles meet the requirements of centrifugal fans.

For temperature-resistant centrifugal fans, attention should be paid to the change of gas temperature and whether there is a maximum temperature exceeding the permissible temperature of centrifugal fans.
