PL24-48 foam - water dual-purpose fire a gun, PL series of fire cannon advantages: the jet set, long range, large fire area, multi-function, easy operation, the gun barrel can be rotated and positioned locking features. It can be equipped with various types of foam fire engine, fire boats, high platform, fixed fire turret and fire pipeline. Main specifications and technical parameters and performance standards are in line with People's Republic of China GB19156-2003 "fire artillery General technical requirements" Second, the principle PL Series foam / water cannon dual mainly by the base, housing, sprinklers, barrel, horizontal Rotary and other institutions. Foam liquid from the base into the housing, then through the diffusion nozzle atomization, and the intake air from the barrel of the tail formation of air bubbles, foam injected by the barrel out the fire, the operator can adjust the horizontal rotation and pitch position of the gun barrel quasi-fire point, as far as possible should spray jet wind, fire that is safe and can give full play to the performance. Third, the performance parameters Model PL24 PL32 PL40 PL48 supporting flow (L / S) 24 32 40 48 Rated working pressure (MPa) 0.8 Working pressure range (MPa) 0.5-1.2 maximum range (≥m) foam mixture 40,455,055 water 45,505,560 expansion ratio (20 ° C) ≥6 25% dialysate time (20 ° C) ≥2.5 pitch angle (°) -30 ~ + 70 level back angle (°) 360 flanged connection mode (divided car fixed and fixed connection with ball)
