1. Overview of wet fire extinguishers
Wet
Fire Extinguisher is a common fire-fighting equipment suitable for various places, such as residences, public places, offices, etc. The fire extinguisher is mainly composed of a water pump, a pressure tank, a nozzle, a valve and other components. Its working principle is to spray water and a special foam mixture onto the fire source to form a covering layer, making it difficult for the fire source to contact oxygen and eventually be extinguished.
2. Working principle of wet fire extinguisher
The working principle of wet fire extinguishers is based on foam fire extinguishing technology. After mixing foam and water, foam liquid is formed through pressure, vibration and other means, and then the foam liquid is sprayed to the fire scene to extinguish the source of the fire and prevent the spread of the fire.
During use, the wet fire extinguisher must first pump out the water in the pressure tank, then pump the water into the pipeline through the pressure release valve, transport it from the pipeline to the nozzle, and mix with air to form foam. After the foam is obtained, the nozzle begins to spray The foam liquid quickly covers the entire burning area, reducing the temperature of the burning area and quickly extinguishing the fire source.
3. Application scenarios of wet fire extinguishers
Wet fire extinguishers are widely used in various indoor places, such as residences, shopping malls, hospitals, schools, etc. Especially in places that are flammable and explosive, such as chemical warehouses, pharmaceutical factories, etc., wet fire extinguishers should be used to extinguish fires.
In short, wet fire extinguishers are common fire-fighting equipment that can effectively extinguish fire sources and protect people's lives and property. When using it, you need to pay attention to its usage method and prevent misoperation to avoid unnecessary losses.
