Recently, the "high-pressure water mist fire extinguishing system" project of Qinling Zhongnanshan Tunnel Management Center undertaken by Traffic Control Fire Company, a subsidiary of mechanization company, successfully passed the acceptance and was put into use.
The "high-pressure water mist fire extinguishing system" fully covers key areas such as the data room, power distribution room, and monitoring hall of the Zhongnanshan Tunnel Center, improving the overall fire safety performance of the tunnel management center, reducing maintenance costs, and meeting environmental protection requirements.
The successful implementation of this project is an important step for mechanization companies to help the high-quality development of enterprises with new quality productivity, and also accumulates experience for the development of modern fire protection industry.
Technical Brief:
"High-pressure water mist fire extinguishing system" is a new type of fixed fire extinguishing system that uses water as the fire extinguishing medium. It uses a special sprinkler head to split water into fine droplets under a specific working pressure for fire extinguishing, which has the characteristics of high efficiency, economy and wide range of application.
Compared with traditional fire extinguishing systems, this system has obvious advantages: First, high reliability. The fire is extinguished by continuous water supply through a high-pressure piston pump, which effectively prevents re-ignition. The second is safety and environmental protection. Water is used as the fire extinguishing medium, which has no pollution to the environment and is suitable for manned places. The third is electrical insulation. The diameter of the droplets is less than 50μm, and the electrical insulation is good, which is suitable for electrical places. Fourth, the water consumption is small. Water consumption is much lower than other fire suppression systems, eliminating the need for large water tanks and fire pump rooms. Fifth, it has a long life. The key components are made of high-quality stainless steel, which has strong corrosion resistance. Sixth, economic optimization. The pipe diameter is small, the installation difficulty is low, the maintenance is convenient, and the maintenance cost is low.
