我站于2014年建成了15号航空液压油高压流量标准装置。经测试,装置工作压力达到28MPa;流量范围为(0.01~5)m3/h;介质最高工作温度达80℃;装置不确定度优于0.1%(k=2)。装置中油箱作为容纳油品的容器,兼具散热、分离液体中气体和沉淀污物的功能。装置由于工作在高压状态,功率损耗大,因此对油箱排气、散热及过滤功能要求更高。本文结合液压知识 I stood in 2014 built 15 aviation hydraulic oil high pressure flow standard device. After testing, the working pressure of the device reaches 28MPa; the flow range is (0.01 ~ 5) m3 / h; the maximum working temperature of the medium reaches 80 ℃; the uncertainty of the device is better than 0.1% (k = 2). The fuel tank in the device serves as a container for containing oil, and has the functions of dissipating heat, separating gas in the liquid and precipitating dirt. Due to its high voltage operation, the device consumes a large amount of power and therefore requires more fuel, air and heat removal and filtration functions.
