First, the characteristics of fire four-wheelers

l, select four; medium-range, single-disc air-cooled, big and stiff engine to ensure the driving power of the four-wheeled fire truck.

2. The drive adopts rear drive shaft drive and equipped with reverse gear mechanism to make driving and turning head more convenient and quicker; overcoming the traditional chain drive driving instability, especially the load climbing chain slipping or breaking, which is easy to cause accidents and other defects. .

Second, the characteristics of water mist fire extinguishing device

l, the water mist fire extinguisher uses integrated fine atomizing nozzle to make the water mist area more careful, improve the efficiency of cooling and oxygen deficiency and suffocation, and improve the fire extinguishing effect by 30%.

2. The direct current spray utilizes the jet foaming technology to make the foam foam effectively, improve the jetting distance and area of the fire extinguisher, and effectively enhance the fire extinguishing effect.

3. The high-pressure pump uses the Power Dragon products manufactured by Harvey Technology of Germany. The pressure is greater than 10 MPa, and the flow rate is greater than 38 L/min. At present, domestic similar products have not yet reached this performance.

4. The high-pressure pump adopts a 1/2-speed direct-coupled device to improve the working stability of the high-pressure pump and prolong the service life of the high-pressure pump.

5, high-pressure water design has added a two-stage reflow device, making the engine start easier and more efficient.
