Jack test system

The utility model provides a jack testing system which comprises an oil tank, the oil tank is connected with a gear pump set and a variable displacement piston pump set which are relatively independent through an oil suction filter, and the gear pump set is connected with a main control valve set through a tubular one-way valve and a first high-pressure filter. The variable displacement piston pump set is connected with the main control valve set through a second high-pressure filter, and the main control valve set is connected with an axial cylinder used for providing axial loading for the jack to be tested and a radial cylinder used for providing radial loading for the jack to be tested and controls corresponding loading, pressure maintaining and unloading actions. The test system is used for detecting the performance of the jack after the jack is produced and completing the standard loading of the jack in the axial direction and the radial direction. 本实用新型提供了一种千斤顶测试系统，它包括油箱，所述油箱通过吸油过滤器与两套相对独立的齿轮泵组和变量柱塞泵组相连
