How to analyze the fault of the operation method of the fire exhaust fan

Release Time：2021-07-20

Fire-fighting smoke exhaust fans are more common, and the key is used for fire fighting. It can be seen from the name that this kind of machinery and equipment is key to exhaust thick smoke, so it is very common. Fire-fighting smoke exhaust fans can be manually opened or fully automatically opened. Due to the uniqueness of machinery and equipment, the actual operation method must be grasped, and the startup item should be started at a moderate opportunity. Then, what is the appropriate operation method of fire-fighting smoke exhaust fan.
1. The control cabinet of the fire-fighting smoke exhaust fan also has manual, full-automatic actual operation method, zero-line live wire and over-voltage and under-voltage device. If over-voltage and under-voltage protection is detected in the three-phase AC circuit, the maintenance posture will be immediately executed when the fire-fighting smoke exhaust fan is out of phase error and all one-phase leads, the switching power supply of the main power supply circuit will be disconnected, and the load will be quickly maintained, and the common fault audible and the alarm will be transmitted.
2. In manual or automatic startup, the centrifugal fan can only be started after confirming that the outer wire of the smoke exhaust fire damper has been connected and is relatively disconnected. In full automatic case, when the fire alarm is signaled, the machine and equipment will send out an audible and visual alarm, and the fire exhaust fan will be started in addition.
3. The fire smoke exhaust fan control system is used to operate the fire smoke exhaust fan. It can operate the smoke exhaust system to implement the reservation posture. The fire smoke exhaust fan receives the feedback data signal of the fire smoke exhaust fan, monitors the branch situation of the fire smoke exhaust fan, carries out communication network with the superior leadership monitoring system, and transmits light control information to relevant staff. When the fire monitoring receives the fire accident data signal, the control box of the linked fire smoke exhaust fan starts the fire smoke exhaust fan and opens the smoke exhaust fire damper to discharge the smoke in the room from the ventilation duct to the outdoor, so as to achieve the actual effect of the smoke exhaust system.
How to analyze the fault of fire exhaust fan.
1. Smoke exhaust fan motor grease quality is poor, deterioration or excessive filling, containing dust, sticky sand, dirt and other miscellaneous fire smoke exhaust fan quality, affecting the motor fever caused by bearings, which reminds us to do a good job in daily use Fan cleaning work.
2. There will be noise problems when the fire exhaust fan is used. The main reason for this problem is the collision between the components in the exhaust fan. When installing the exhaust fan, you need to pay attention to adjusting the distance between the blades.
3. When the fan suddenly shuts down during application, people should check whether there is a problem with the switching power supply. If it is not the problem with the switching power supply, there will be an abnormality in the internal route. When applying the exhaust fan, be careful not to let the axial flow fire exhaust fan overload operation.
