Fire hose, vacuum, hose collapse, residual water, hose line stability.Abstract
The article examines the problem of fire hose deformation under negative pressure in the residual fire extinguishing agent return systems. It has been shown that when creating a vacuum inside the sleeve line, the sleeve can flatten due to atmospheric pressure. Analysis of the conditions for sleeve collapse occurrence was conducted, and permissible vacuum values were determined. The criterion for the stability of the sleeve line during water return has been proposed. The research results can be used in the development of wastewater return systems in fire trucks
