Single -speed fire smoke is a common and important device to control the flue gas and harmful gases generated during the internal fire of the building.It is mainly used to help eliminate smoke and keep the air smooth when the fire occurs to provide safe evacuation channels and reduce the risk of fire spread.It uses a single fixed wind speed to run, which has the characteristics of high reliability and simple structure. It is widely used in various buildings such as commercial buildings, residential buildings and public places.
The working principle of a single -speed fire smoke exhaust fan is based on a fan that the smoke is drawn from the inside of the building through a fans.When the fire occurred, the smoke exhaust system was started, and the smoke exhaust fan started to run.The negative pressure generated by the fan allows the smoke to flow from the fire area to the exhaust port, and then discharge outdoors through the smoke exhaust pipes.At the same time, fresh air will enter the building through other ventilation systems to maintain normal airflow.
Single -speed fire smoke exhaust fan is mainly used to eliminate fire and heat at the fire scene, and maintain the availability and safety of evacuation channels.It has the following functions:
1. Tobacco discharge function: The main function is to exclude the smoke generated by the fire scene.When the fire occurs, the flue gas will spread rapidly, affecting the attention and breath of personnel, and increasing the difficulty of escape.The smoke exhaust fan discharges flue gas from the inside of the building through a strong wind, maintains the smooth flow of evacuation channels, and provides escape channels and rescue conditions.
2. Calls exclusion: The heat generated by the fire is an important factor in the spread of fire and the safety of the safety of the personnel.While eliminating flue gas, the single -speed fire exhaust fan can also excrete the heat generated by the fire, reduce the temperature of the fire scene, reduce the speed of the fire, and provide better rescue conditions for firefighters.
3. Keep stress difference: During the fire, there will be a certain pressure difference within the building, usually due to the rise in the heat generated by the fire source.Single -speed fire smoke exhaust fan can maintain the pressure difference between the internal and external pressure of the building through a strong wind exhaust capacity, prevent flue gas from flowing, and keep the evacuation channel smooth.
4. Automatic control: It is usually equipped with an automatic control system that can automatically start and stop operation according to the signal of the fire detector or the fire control center.This can achieve rapid response, timely exclude smoke and heat, and ensure the safety of personnel.
5. High -efficiency wind power: It has strong wind power, can generate a large amount of exhaust volume, and quickly exclude the flue gas and calories at the fire scene.It usually adopts high -efficiency fan design and professional airway system to ensure the efficiency and reliability of air exhaust effects.
6. Reliability and durability: Usually high -quality materials and advanced manufacturing processes have high reliability and durability.They are usually strictly tested and certified that they can run stably under harsh environmental conditions and have a longer service life.
