10000公斤/厘米~2高压容器的研制

国家地震局地球物理研究所 本高压容器是我国第一台10000公斤/厘米~2液体围压的三轴试验容器。容器的高压腔尺寸为φ8.5吤厘米 可放置φ2.5࡫.5厘米的岩石样品及各种探头。它以9138油泵为侧向压力源 可产生0-10000公斤/厘米~2的围压 能模拟地壳深部30公里处的压力环境。与长江500型岩石三轴应力试验机配套使用 可进行岩石三轴压力破裂试验。容器简体采用了三层缩套配合结构 液压油进出口及电测导线的引出均在底座及大柱塞上轴向开孔 以免应力集中。上密封和下密封采用三角垫及密封环密封 引线密封采用锥塞及密封绝缘锥套密封。

THE DESIGNING OF A 10kb HIGH PRESSURE VESSEL

The dimension of the high pressure space of the vessel is φ8.5 × 40 cm and a rock sample of φ2.5 × 5.5 cm and various gages can be put in it. The pressure source is a type 9138 oil pump. It can produce 0-10 kb confining pressure, which corresponds roughly to that at 30 km depth in the crust. In conjunction with a CJ-500 test machine, the triaxial compression experiment on rocks can be performed.A t.rilayer structure of the vessel has been adopted. The oil entrance is in the bottom and the electric signal leads are in the axial plug. For upper and lower seals triangle pads and "O" rings are used. For electric signal leads a cone plug and a insulation cone sheath are used.
