摘　　要：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。For, application in big mining height hydraulic support＇s cylinder within the load test, this paper designs a column strength test system with 20 000 kN working resistance which combined with the new release of GB25974.2-2010 for coal mine hydraulic support and jack technical conditions of Part 2 standard requirements. It mainly consists of emulsion pump and pressurized hydraulic system, loading test bed and CAT system. Through the practical application, it turned out that the test bench has reasonable structure, stable performance and it can support column factory test requirements. meet all of the following φ630 Bore hydraulic
