液压油是液压系统传递动力的介质,它对于液压系统的可靠性,机械零件的摩擦磨损,液压机械的性能,使用寿命及降低能量消耗等方面均具有直接的影响。因此,正确合理选用和评价液压油的工作已愈来愈引起人们的重视。为了选择一种较佳油品,供工程施工机械在高原低温(零下30℃左右)条件下使用,我所研制的液压油泵试验台,去年年初在齐齐哈 Hydraulic fluid is the hydraulic power transmission medium, which has a direct impact on the reliability of the hydraulic system, the friction and wear of mechanical parts, hydraulic machinery performance, service life and reduce energy consumption. Therefore, the correct and reasonable selection and evaluation of hydraulic oil work has drawn more and more attention. In order to choose a better oil for construction machinery in the plateau low temperature (minus 30 ℃ or so) under the conditions of the hydraulic pump I developed the test bed early last year in Qiqiha
