Knapsack mine saddled with pulse pressure spray gun type ore pulse pressure spray gun, high voltage pulse high-voltage pulse of fire extinguishing equipment fire extinguishing installations (QWMB12) - 
 Use of compressed air moment release of the great kinetic energy, air and liquid fire extinguishing medium, such as water, mixed, by a sudden expansion of the atomizing nozzle to accelerate a collision in the millisecond time, instantaneous injection to produce high-speed high-density water mist flow, direct access to the root of the source of fire, set off by wind, asphyxia, cooling three kinds of fire-based management in one, so as to achieve fast and efficient fire fighting purposes. High-voltage pulse fire extinguishing installations, especially for the initial fire fight warehouses, airports, coal, petrochemical, transport, commercial establishments and homes. Mainly used in the fire early, especially in the narrow space, underground, 
 Transport and small-scale A, B, and class C fires put out more of their good performance. The early use of fire in the forest and the natural environment is also an excellent choice; while its inhibition of the fire is also very effective. The main technical parameters of the high-voltage pulse fire extinguishing installations are as follows: 
 A water tank capacity: ≥ 12 L 
 2, the pulse jet clearance time: ≤ 3 s 
 Storage cylinder volume: 2 L 
 4, the number of effective pulse jet: ≥ 10 
 Storage cylinders Nominal pressure: 30 ± 1 MPa 
 6, the spray distance: ≥ 10 m 
 7, the jet exit velocity: 80 to 120 
 m / s Arrangement: injectors, cylinders, bottle valve, the 300/27/6 Pakistan bipolar reducing valve, brace, pressure gauge, safety valve, ejector inlet pipe, injection into the trachea, water tanks, water tanks into the trachea
