MOBILE FIRE EXTINGUISHING PLANT WITH FOAM GENERATION USING THE COMPRESSION METHOD Russian patent published in 2018 - IPC A62C27/00 

FIELD: fire safety.

SUBSTANCE: invention relates to fire fighting equipment, namely to the fire-fighting ground vehicles with the generation of foam using the compression method. Mobile fire extinguishing plant with foam generation using the compression method includes the mixing chamber, which is connected at the outlet with the foam supply device, which supplies foam to the fire bed, and the water supply system, which is connected to the inlet of the mixing chamber by the pipelines, including the water supply pump with the drive, the foam generation concentrate supply system including the foam pump with the foam pump drive, as well as the air supply system including the air compressor with a drive. According to the invention, it is further provided with the drive motor, and the drives of the air compressor and the foam pump are made in the form of kinetically connected adjustable hydraulic transmission of the air compressor drive and an adjustable hydraulic transmission of the foam pump drive.

EFFECT: technical result, which is achieved by the claimed invention, consists in the possibility of obtaining the foam that is necessary according to the foam head and density in any operating modes of the water supply pump, including those without switching on the water supply pump, if the water head in the fire hydrant is sufficient to supply water without an additional increase in the head of the water pump, or with the inclusion of the water supply pump at a reduced speed, in particular when taking water from fire hydrants with insufficient support, and also in provision of the possibility of the compressor rotation speed control, in particular, to provide in provision of smooth startup and shutdown of the compressor.
