Fire extinguishing technology of water-based automatic fire extinguishing devices for mining vehicles
golden mean fire-fighting equipment co.ltd is an early unit engaged in the research, development and production of water-based automatic fire extinguishing devices for mining vehicles with comprehensive fire prevention and extinguishing measures in coal mines. The automobile fire prevention and spontaneous combustion water-based automatic fire extinguishing systems developed and produced by it, and the new energy battery compartment automatic fire extinguishing technology are relatively advanced special fire extinguishing technologies in my country. This technology integrates detection, alarm and fire extinguishing technologies to enable remote IoT monitoring operations. At the same time, the device can be used manually. Automatic and mechanical emergency starting. The device can be used to protect vehicle engine compartments in gold mines, iron ore, copper mines, coal mines and other areas.
When designing and installing comprehensive fire prevention and extinguishing measures for coal mines, water-based automatic fire extinguishing devices for mining vehicles should comply with relevant standards. Post-installation inspection and acceptance should meet the following requirements:
1. Comprehensive fire prevention and extinguishing measures for coal mines. Water-based automatic fire extinguishing devices for mining vehicles should check the storage pressure of the water-based pipe network and check whether the capacity of the water-based bottle group is the same as the pressure of the pharmaceutical pipe network to meet the design requirements.
2. When nitrogen is used as a driving gas, its purity and dosage should meet the design requirements, and when the fire extinguishing device is started, it should be checked that the nitrogen driving pressure should ensure that the residual amount of the agent bottle meets the relevant standards.
3. Design scheme of detection system, spray system, medicine bottle group, control unit, water-based conveying pipeline, alarm and other important components. Conduct a comprehensive inspection of important components.
4. The amount of water base used in different protected spaces is different. Before installation, check the model and specifications of the medicine bottle set, including the number and specifications, including: the bottle model used (user), pressure holding date, filling time, filling temperature, nitrogen pressure storage operator, filling operator , filling pressure, etc., weigh the bottle group if there is no problem with each parameter to further verify the certainty of the water-based tank model.
5. Insufficient pressure is the main reason that affects the spraying effect of water-based automatic fire extinguishing devices for mining vehicles and comprehensive fire prevention and fire extinguishing measures in coal mines. The pipe is squeezed. The nozzles are caused by obstructions. Therefore, when accepting the vehicle's automatic fire extinguishing device, a sealing test should be conducted on the water-based bottle set first, to check whether the water-based pipe is deformed in appearance and whether the water-based nozzle is cleaned to ensure that the water-based bottle achieves the ideal spray effect.
