Research and development of fire extinguishing equipment for passenger compartment

Abstract

In view of the problems of the passenger vehicle, such as single fire-fighting method, low degree of automation, long response time, poor fire extinguishing effect. In this paper, the high-pressure water mist fire extinguishing equipment for passenger compartment was researched and developed. The defects and characteristics of fire prevention and control of passenger vehicle were analyzed firstly, and on this basis, the functional requirements and selection schemes of fire prevention and control equipment were proposed. Then, the selection scheme was used for trial production of equipment, and the fire extinguishing performance test was carried out to verify the effectiveness of the equipment. The test results showed that the equipment had good fire extinguishing effect. After the equipment was activated, the fire in the passenger compartment was significantly suppressed. After 3 s of start-up, the open fire was almost extinguished. After 10 s of start-up, the toxic black smoke almost disappeared and the average temperature in the passenger compartment dropped to 60°C.
