Water mist (watermist) is relative to the concept of "waterspray". It uses special water mist guns to generate water particles by high-pressure water spray. Water mist fire extinguishing is mainly through the dual role of high efficiency cooling and anoxic asphyxiation.

Characteristic description of fire fighting motorcycle:

I. Characteristics of Fire Fighting Four-wheeled Vehicles

1. Select four-stroke, single-cylinder air-cooled, large displacement engine to ensure the driving power of four-wheel fire truck.

2. The drive adopts rear drive shaft drive and is equipped with reverse gear mechanism, which makes driving and turning more convenient and fast. It overcomes the disadvantages of unstable driving of traditional chain drive, especially the slippage or breakage of the chain on load climbing, which easily causes accidents.

2. Characteristics of Water Mist Fire Extinguishing Devices

1. The water mist fire extinguishing gun adopts integrated fine atomizing nozzle, which makes the water mist area more compact, improves the efficiency of cooling and hypoxia asphyxiation, and improves the fire extinguishing effect by 30%.

2. Direct current spray makes use of jet foaming technology to make foam more effective foaming, improve the distance and area of fire extinguishing gun, and effectively enhance the extinguishing effect.

3. High-pressure pumps are made of Weililong products manufactured by German Harvey technology. Its pressure is greater than 10MPa and flow rate is greater than 38L/min. At present, domestic similar products have not reached this performance.

4. The high-pressure pump adopts a 1/2 speed direct connection device, which improves the working stability of the high-pressure pump and prolongs the service life of the high-pressure pump.

5. The design of high-pressure waterway adds a secondary reflux device, which makes the engine start more easily and quickly.
