Research on Jet Combustion Test Equipment of Difficult Combusted Hydraulic Liquid
Abstract：In order to enhance the difficult combustion performances inspection and quality control of the difficult combustion hydraulic liquid,two jet combustion test methods of the hydraulic liquid were introduced.Base on a hydraulic pump system to replace the nitrogen cylinder as the pressure source,with the selection designs on the nozzle,the hydraulic system as well as the ignition and air exhausting system,a first set domestic jet combustion test equipment was researched and developed.The jet combustion test equipment and the ISO 15029-1 evaluation method was applied to the jet combustion test with different hydraulic liquids.The test results showed that the flame sustained time of water-glycol hydraulic liquid was 0,the flame sustained time of the water free full synthetic hydraulic liquid was 2.3～9.8 s and the flame sustained time of the antifriction hydraulic oil was 49.8～52.1 s.The test results could reflect the difficult performances of the hydraulic liquid products.Therefore the test equipment could be applied to the inspection and test on the difficult combustion of the hydraulic liquid.
