Fire fire smoke is no stranger to us. It can be seen in many places in life. Fire smoke is mainly used in ventilation systems such as highway tunnels, railway tunnels.Fire fighting smoke has a continuous area. Under normal circumstances, it can be hung on both sides of the tunnel.Lets introduce the maintenance methods of fire smoke:
1. Break the main power supply, hang the "prohibiting closing of the gate" sign, and check whether the motor ground wire is good.
2. Tighten the screws and axis of each part.
3. Detect whether the insulation resistance of the motor meets the regulations and check the main circuit contact.If the contact is severely abstructed (the contact point is worn to 1/3 of the thickness of the original), the contact should be replaced.
4. Adjust the tightness of the belt, use the hand plate to move the wind wheel, and observe whether the rotation is stable.
5. Check and replace the pads and sealing fillers between the joint surfaces.
6. Clean motor and wind wheels, filters and inside of the case.For the paint out of the paint, it should be made up.
7. Add lubricating oil to the rotating site to ensure the flexibility and stability of the bearing and bearing.
8. Check whether the mechanical opening and closing movements of the regulating valve are reliable and flexible, and the opening and closing angle signs are clear.
9. Whether the manual startup indicator light, voltage, and current meter work are normal, whether there is no sound in the operation of each component of the fire exhaust fan, and whether the three -phase current value is balanced.
10. Check whether the components in the remote control point control box are normal.
11. Three consecutive start and stop, check whether the remote control of each point is correct and reliable.
12. Two hours of trial transportation, observe whether the temperature of the motor bearing and the increase in motor temperature are normal.Ensure that fire firewipes are operating normally.
