| 摘 要： | 泄漏量是大多数液压元件出厂试验的必检项目，提出用气动测量的方法进行检测，并在理论上对其可行性进行了探讨，证明了能够利用气动量仪对液压元件的泄漏量进行定量检测。利用这种方法可消除液压元件在泄漏量检测过程中出现的堵塞现象，节约能源，提高工效。

| Abstract: | Leakage flow rate is the item bound to be measured for the great majority of hydraulic components as final products. In this article,a leakage checking method by means of pneumatic measuring is proposed and its feasibility in theory discussed. By means of this method,the leakage flow rate of hydraulic components can be measured quantatively,the stoppage frobrem in the processes for checking the leakage flow rate of hydraulic components can be get rid of. It saves the energy and improves checking efficiency. |
