山东矿业学院和兖州矿业（集团）公司机械制修厂、杨村煤矿共同研制的多功能液压阀试验台，能够对煤矿采掘设备中的各类液压阀进行性能试验。它采用电磁比例溢流阀进行压力调整，压力范围宽，数据采集准确，取得了很好的效果。 该试验台的最大特点是全部试验数据都由计算机自动 Shandong Mining Institute and Yanzhou Mining (Group) Co., Ltd. Machinery Factory, Yangcun coal mine jointly developed multi-purpose hydraulic valve test bench, coal mining equipment in various types of hydraulic valve performance test. It uses electromagnetic proportional pressure relief valve for pressure adjustment, wide pressure range, accurate data acquisition, and achieved good results. The most important feature of this test bed is that all the experimental data are automatically by the computer
