液压泵和液压马达试验系统从功能利用方式分为非功率回收和功率回收两大系统。一般说,前者宜试验小功率元件,后者适于试验大功率元件。 Hydraulic pump and hydraulic motor test system from the functional use of the system is divided into non-power recovery and power recovery of the two systems. In general, the former should test low-power components, which are suitable for testing high-power components.
