FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment, to manual and stationary devices for generation of air-mechanical hybrid foam of medium expansion rate or sprayed water. In a combined fire extinguishing installation, comprising a medium expansion foam generator, comprising a housing with a mesh cassette installed inside the housing and a means for supplying a fire extinguishing substance to the mesh cassette, as well as a means of connecting to a pressure pipeline for supplying a fire-extinguishing substance, generator housing is made cylindrical with annular projection concave inside the housing from the foam outlet side and with the annular projection convex to the outside of the housing on the side of the fire extinguishing agent supply to the mesh cassette, mesh cassette is made of coaxially installed one inside the other inner, medium and external annular rims and two meshes located with a gap relative to each other, one of which is fixed by edges in gap between mating side surfaces of external and medium rims, and the other mesh is fixed by its edges in the gap between the mating side surfaces of the medium and inner rims, and is installed in the generator housing on the fire extinguishing substance supply side to the meshes cassette with the support against the annular projection concave inside the housing, and the fire extinguishing agent supply means to the mesh cassette in the generator is made in the form of a nozzle attached to the generator housing by means of centring stops and equipped with a branch pipe with a means of connection to the fire extinguishing agent supply pipeline.
EFFECT: increased efficiency of extinguishing emergency transport, forest, emergency industrial and other fires.
