Mining and fire pulse pressure spray gun

Pulse pressure spray gun is a water atomization fire extinguishing equipment. It is the use of instantaneous release of compressed air generated great momentum, so that air and liquid extinguishing medium (such as water) in collision with each other within milliseconds of time mixing nozzle after acceleration, sudden expansion of atomization, the instantaneous injection, resulting in high speed, High-density ultra-fine mist flow, direct fire source roots, set to blow off, asphyxia, cooling mechanism in one of three kinds of fire, the wrong man to achieve rapid and efficient fire-fighting purposes. It is a new application of aerodynamics in the area of ??fire fighting. ? Features high efficiency: Due to the small atomized particles effectively cover large surfaces, the same extinguishing media, extinguishing area up to 5 times. ? Very powerful: Since the release of atmospheres in the millisecond level amount of time, so that the average muzzle velocity mist flow of 120 m / s, the impact is great, can achieve instant fire. ? Pollution, saving energy: with cheap water and air as the extinguishing material, not only non-toxic pollution, and low cost of use and maintenance. ? High mobility: Full means the weight ratio is less than 35 kg, very short assembly time off in favor of the firefighters to reach the fire, to stop the expansion of the initial fire, the effect is particularly evident. ? Wide range: both destroy solid fire, the fire can destroy liquid and gas fire, for fifty thousand volts of electrical fire at one meter away can secure extinguished.
