Manufacturers explain that affect multiple industries fire exhaust fan normal start of the factors fire exhaust fan, as a new ideal fire necessary facilities, widely used in construction. Fire exhaust fan in everyday use need to pay attention to daily maintenance and maintenance, in the face of situations, if fire exhaust fan can not start properly, will bring very serious consequences, summed up the four manufacturers influence fire exhaust fan starts factors: 1. Power failure, exhaust fan, plug connection is bad, the lack of current 2. wiring faults, such as loose, short, other wiring errors. Limiting device (such as air switch) 3. line does not match, exhaust fan price, can not meet the start-up current. The motor was damaged, leading to not start. These are the reasons summarized in factory fire exhaust fan does not start. When we encounter such a failure from the four aspects of the investigation, which can guarantee fire exhaust fan can start properly. Fire exhaust fan and kitchen exhaust fan is the same kind of dedicated fans do? Currently, the exhaust fan is marketed more broad range of applications of a new fan. For example, an ordinary exhaust fan fire exhaust fan for the kitchen, can be referred to as the exhaust fan, so that the majority think the two are the same kind of fan. Fire exhaust fan and kitchen exhaust fan is completely different, not just applications of its function is very different. Fire exhaust fan must reach 280 degrees temperature, exhaust fan principle, and the kitchen exhaust fan reach 100 degrees can be, under normal circumstances, and the fire alarm host linkage exhaust fans are anti-handling in the fire system Smoke systems. No side exhaust pipes set exhaust valves, exhaust fan and exhaust pipe connections smoke damper settings. Note that exhaust valve and smoke damper is completely different device functions. Exhaust valve usually normally closed, high-temperature exhaust fan fire, open fire, and alarm host linkage, open the condition that an outbreak of fire alarm system (probe alarm) Fire Alarm System in the automatic state, exhaust valves open automatically linked exhaust fan starts. Through the above description, and general exhaust fan fire exhaust fan is completely different, whether the installation location or features and principles are different, and I hope you can understand after correctly distinguish the two fans, the choice of avoiding errors .
