Fire protection of mining vehicles has always been a hot topic of concern to mining companies. In recent years, with the increase in the use of mining vehicles such as articulated mine cars, coal mine monorail cranes, support trucks, rock drilling rigs, scrapers, loaders, wide-body dump trucks, etc., more and more vehicles have been exposed Security risks. Among them, electrical fires in mining vehicles are an important factor affecting mining vehicle fires, and their safety protection cannot be ignored. According to the temperature value in its protection area, the perfluorohexanone temperature automatic fire extinguishing device can achieve real-time and accurate control of its fire, extinguish the fire from the source, and effectively solve the fire extinguishing problem of mining vehicles.

Analysis of the causes of fire caused by electric mine car failure:

1. The line from the battery to the starter is rubbed, causing leakage and causing a fire.

2. When the fuse of the electric switch is blown, an electric arc is ejected, causing surrounding flammable materials to burn and catch fire.

3. The wires are aging, the line load is too large, the contact resistance is too large, the temperature rises, and combustible materials catch fire.

4. Cables and wires are aging and damaged, and the insulation strength is reduced, causing leakage and short circuit and fire.

The perfluorohexanone temperature-sensing self-starting fire extinguishing device abandons the traditional fire protection design concepts of "large range" and "total flooding". It aims at safety, environmental protection, no residue, maintenance-free, and high cooling effect, and adopts an integrated and miniaturized design. , modular assembly, can be used in a single set or in multiple groups, especially suitable for fire protection of electrical equipment with compact structure and small internal space of mining trucks.

Application advantages of new energy mine car 1230 Automatic Fire Suppression Systems:

1. Green and environmentally friendly: Using a new type of perfluorohexanone fire extinguishing agent, there is no residue after extinguishing the fire, and it can physically decompose by itself without damaging the vehicle lines. In addition, it will not destroy the atmospheric ozone layer or pollute the atmospheric environment.

2. Efficient fire extinguishing: With a fire extinguishing concentration of 4%-6%, physical cooling and chemical inhibition can be used to quickly suppress, suffocate and extinguish fires.

3. Human safety: Perfluorohexanone fire extinguishing agent has low toxicity and is harmless to the human body, and can be used to extinguish fires in manned environments.
