Abstract Purpose. The study of the dependence of generated air-mechanical foam multiplicity on the socket length of foam generator of the fire-hose barrel SPRUK 50/0.7 «Viking».
Methods. Experimental studies were carried out on the basis of the University of Civil protection of the Ministry of Emergency Situations of the Republic of Belarus in accordance with the requirements of Standard of Belarus 11.13.14-2009 «Manual fire barrel. General specifications».
Findings. It was stated that the prototype of the foam generator with a socket length of 220 mm was the most optimal. It was found that with increasing consumption of foaming agent, the multiplicity of generated foam grows, reaching a maximum at a flow rate of Q = 2 l/s, and then begins falling, therefore, to form an air-mechanical foam, it is advisable to use the third position of the flow regulator of fire-hose barrel. A prototype foam generator with a socket length of 220 mm allows you to apply the foam with the highest ratio and the required range of foam jet. It has also been established that to obtain a foam forming solution, it is necessary to use a fire pump foam mixer.
Application field of research. Extinguishing fires with air-mechanical foam using a fire-hose barrel SPRUK 50/0.7 «Viking».
Conclusions. In the course of experimental studies of prototypes of foam generator, it was established that the foam generator with a socket length of 220 mm allows to achieve the greatest range of the foam jet. Reducing or increasing the length of the socket leads to a decrease in the range.
Keywords foam generator, low multiplicity foam, mesh, socket, stand, range of foam jet, foam multiplicity
