摘　　要：针对液压坑道钻机夹持器、油缸和油路阀组等液压元器件在煤矿井下维修后需试验其密封性能、机能执行可靠性的需要,设计了一种煤矿井下用小型压力试验机。压力试验机由液压工作站和电控柜两部分组成,试验机测试系统由液压油源子系统、循环过滤冷却子系统、接油盘收集子系和油箱子系统四部分组成,工作加载采用电液比例控制技术进行无级调压,应用三维软件直观展示了试验机搭建后的三维模型。Aiming at the need for hydraulic components such as hydraulic tunnel drilling rig grippers,oil cylinders and oil circuit valve groups to be tested for their sealing performance and performance reliability after maintenance in underground coal mine,a small pressure tester for coal mine was designed.The pressure tester is composed of a workbench and an operation cabinet.The tester test system is composed of four parts:hydraulic oil source subsystem,circulating filtering and cooling subsystem,oil receiving tray collecting subsystem and oil tank system.The liquid proportional control technology is used for stepless pressure regulation,and built after the three-dimensional model of the tester is visually displayed by using three-dimensional software.
