Abstract:

This report deals with the ignition of hydraulic fluids by means of compression processes caused by rapid pressurization of air filled portions of hydraulic and pneumatic systems. A theoretical analysis of the gas temperatures attained during the compression process is presented. Employing this analysis a reasonable correlation was obtained between the experimental conditions under which ignition would occur during a compression process and the spontaneous ignition temperatures of the hydraulic fluid. Further analytical studies were made of the parameters which affect the rate of compression during rapid venting of high pressure air or liquid into a pipe containing air at low pressure. The predicted pressure rise rates and maximum pressures were found to be in fair agreement with the experimental results. Author
