Nowadays, more and more buildings are equipped with fire-fighting facilities, and there is a key component in the fire-fighting facilities, which is the fire exhaust fan.

However, it should be noted that if the equipment is used for too long, it will cause a lot of dust or other unclean things inside. If it is not properly removed, it will endanger the normal use of the fire exhaust fan. If the actual effect of the exhaust system is not good or trivial, it will be regretful if it fails to operate and leads to higher disasters.

I will discuss with everyone about the knowledge of daily removal, protection, and maintenance of fire exhaust fans

1、 Adjust the tension of the drive belt used in the fire fan, rotate the impeller with your hand, and observe whether the leather pushing is stable.

2、 Clean the interior of the mechanical and electrical engineering, impeller, filtration equipment, and casing, and apply rust proof paint to address the issue of paint explosion.

3、 Add lubricating grease to the rotating position of the fire exhaust fan to ensure the sensitivity and reliability of the coupling and rolling bearings.

4、 Check whether the opening and closing action of the regulating valve of the fire exhaust fan is firm and agile. Assuming that the regulating valve does not open and close quickly, it should be appropriately disassembled and replaced.

5、 To inspect and replace the gaskets and sealing fillers between the welding surfaces of the fire exhaust fan, it is necessary to ensure that these gaskets and sealing fillers are intact.

6、 The fire smoke exhaust fan can be manually started to check the display light, current quantity, and output power of the ammeter to ensure that they are normal. It is also necessary to check whether there is a buzzing sound in the fan components and whether the three-phase current values are balanced.
