Works: the high-voltage pulse the extinguishing device qwmb12-great kinetic energy of the compressed air instantaneous release, the clash mixing of air and liquid fire extinguishing medium (such as water) in the millisecond time, a sudden expansion of the atomizing nozzle accelerated instantaneous injection, resulting in high-speed, high-density ultra-fine mist flow, direct access to the root of the source of fire, set off by wind, choking, cooled three fire-fighting base management in one, so as to achieve the purpose of fast and efficient fire-fighting. Uses: high-voltage pulse fire extinguishing device is particularly suitable for the Fight warehouses, airports, coal, petrochemical, transport, commercial establishments and houses of the initial fire. Mainly used in the early stages of a fire, especially in narrow spaces, underground, transport and small range of a, b, c class fire fighting more of its good performance. The initial use of fire in forest and other natural environment is also an excellent choice; while it is also very effective to suppress the fire. The high voltage pulse extinguishing apparatus main technical parameters are as follows: 1, tank volume: ≥ 12 L 2, pulse jet clearance time: ≤ 3 s, effective pulse storage cylinder volume: 2L ejection frequency: ≥ 10 5, the gas cartridge Nominal pressure: 30 ± 1 mpa, spray distance: ≥ 10 m 7 jet exit velocity: 80 ~ 120 m / s Arrangement: injectors, gas cylinders, bottle valve, 300/27/6 Pakistan bipolar relief valve, the brace, pressure gauge, safety valve, injector inlet pipe, intake manifold injector, water tanks, water tanks into the trachea
