Embodiment Construction
[0032] Such as image 3 Shown is a foam fire truck injection type positive and negative pressure foam proportional mixing system, the mixing system is connected to the external water inlet pipeline 5 through the foam pump outlet pipeline 9, and the end of the external water inlet pipeline 5 is connected to the water inlet of the pressure water pump 8, The water outlet of the pressure water pump 8 is connected to the water outlet pipeline 10 . This invention is different from the traditional positive pressure system which connects the foam injection port to the water outlet, but creatively connects the main foam inlet to the water inlet pipeline, which can overcome the problem that the foam stock solution cannot be injected when the water pump outlet pressure of the positive pressure system exceeds 12bar .
[0033]Foam tank 24 is provided on the foam proportional mixing system in positive and negative pressure state, and foam tank 24 is connected to the inlet of foam pump 1 th...
