DESIGN PHILOSOPHY OF A HIGH-PRESSURE FOAM GENERATOR
Purpose. Improvement of the УМПГВ mobile foam generating high-pressure installation intending to fight and localize the fires in places difficult of access. Methodology. The information and theoretical investigations of the existing foam generating equipment on which basis the research preproduction work is realized were carried out. Results. The design documentation for the prototype of the УМПГВ installation capable of piping the foam (or its feeding along the holes) with the small sectional area at considerable distances is worked out. Scientific novelty. To generate the continuous foam flow and to eliminate the backup pressure in a pipeline a fairing and a foam generating net connected with it are used in the structure of the foam generator, they are performed movable. This guarantees spraying the whole surface of the net, and movement of the fairing and overshooting of the flow section of the mouth with it ensure regulation of the gas amount being fed to the net, what allows generating the continuous flow of the foam with the average expansion ratio from the pipeline (hole).
