1. Turn off the main power, make the corresponding labeling, and check whether the 3C fire smoke connecting the ground wire is correct.2. Detect whether the insulation resistance of the 3C fire smoke motor meets the regulations and check the main circuit contact.If the joint is severe, the joint should be replaced.3. View and replace the pads and sealing fillers between the joint surfaces.4. Adjust the tightness of the 3C fire smoke, and use the hand disk to move the wind wheel to observe whether the rotation is shaking.Check the screws and joint shafts of each part and be tight.5. Fill in an appropriate amount of lubricating oil to the rotating site to ensure the sensitivity and stability of the joint bearing and bearing.6. View whether the mechanical opening and closing movements of the fire ventilation equipment regulating valve are reliable and sensitive, and the opening and closing viewpoint signs are clear.7. Clean the motor and wind wheels, filters and inside of the case.8. Check whether the components in the remote control point control box are normal.9. Manually turn on the indicator light and voltage, the current meter is normal, whether there is any sound in each component of the fire and ventilation equipment, and whether the three -phase current value is balanced.10. Three consecutive times to start and stop the 3C fire smoke, and check whether the remote control of each point of the fire and ventilation equipment is correct.11. For two hours of trial work, observe whether the motor bearing temperature and the increase in motor temperature are normal.Make sure that the 3C fire smoke work is normal.
The above is the daily maintenance of the 3C fire exhaust fan
