针对应用于大采高液压支架立柱的试验问题,结合新发布的GB25974.2-2010煤矿用液压支架第2部分《立柱和千斤顶技术条件》标准要求,设计了20 000 k N工作阻力的立柱加载试验系统。该试验系统主要由乳化液泵站、增压加载系统、加载试验台和CAT系统等部分组成;通过实际应用表明,该试验台结构合理、性能稳定,能够满足准630 mm缸径以下所有液压支架立柱的出厂试验要求。
In view of the test problems applied to the pillar of large mining hydraulic support, combined with the newly released GB25974.2-2010 Coal Mine Hydraulic Support Part 2 “Technical Requirements of Column and Jack” standard, a column load of 20 000 kN working resistance was designed Test system. The test system mainly consists of emulsion pump station, pressurization loading system, loading test rig and CAT system. The practical application indicates that the test rig has reasonable structure and stable performance, and can meet all the hydraulic support column below 630 mm bore The factory test requirements.
