Matters needing attention in the operation of explosion-proof and anti-corrosion fans

2019-05-15

Dust removalExplosion-proof and anti-corrosion fanIt is a kind of equipment widely used in metallurgy, chemical industry, cement, electric power and other occupations. It plays an important role in the process flow of the entire production system. The defects of this equipment will directly cause the entire production system to fail to work normally. The following editor will introduce to youExplosion-proof and anti-corrosion fanWhat matters should be paid attention to in operation, I hope to help you.

one,Explosion-proof and anti-corrosion fanAlways pay attention to the temperature and smooth cooling of the centrifugal fan bearing.
1. The pressure of rolling bearing is lubricated smoothly: the normal temperature of the bearing should be less than 60°C, 70°C is allowed, the inlet oil temperature is 35°C-45°C, the outlet oil temperature is 55°C-65°C, and the temperature rise is less than 40°C
2. The rolling bearing grease is smooth: the normal temperature of the bearing should be less than 70°C, 80°C is allowed, the inlet oil temperature is 35°C-45°C, the outlet oil temperature is 55°C-65°C, and the temperature rise is less than 40°C
3. Sliding bearing: the normal temperature of the bearing should be less than 70°C, 80°C is allowed, the inlet oil temperature is 35°C-45°C, the outlet oil temperature is 55°C-65°C, and the temperature rise is less than 40°C
3. Sliding bearing: the normal temperature of the bearing should be less than 65°C, and 70°C is allowed, the inlet oil temperature is 35°C-45°C, the outlet oil temperature is 55°C-65°C, and the temperature rise is less than 35°C

two,Explosion-proof and anti-corrosion fanPay attention to the vibration and impact noise of the unit. Always check the amplitude of the bearing housing with a vibrometer. Pay attention to whether there are bumps and other sounds inside the machine.

3. Use an ammeter to supervise the load of the motor, and do not allow the centrifugal fan to run under the frying load for a long time.
4. 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 the use of centrifugal fans.
5. For temperature-resistant centrifugal fans, pay attention to the change of gas temperature, and whether there is a maximum temperature that exceeds the allowable centrifugal fan.
