采用基于国产铰链式六面顶压机二级6-8型大腔体静高压装置中的10/4(即八面体传压介质边长为10mm,二级WC-Co硬质合金立方块截角边长为4mm)组装,选择不同的围压材料和传压硬质合金台棱、圆片,在室温下用ZnTe的高压相变对压腔进行了压力标定。实验结果表明,叶蜡石是较合适的围压材料;但由于传压台棱、圆片自身强度的限制,及一级压腔形成的围压值较低等原因,致使实验没有达到预期的末级压砧围压增强效果。通过结合两种压腔的力学简化模型分析得知,围压材料与二级增压装置的预密封边共同形成了二级压腔的密封边,该大面积密封边消耗了系统的大部分加载力,因此在围压实验中没有观测到二级6-8型大腔体静高压装置压力极限的提高。
Using a 10/4 (based on the octahedron pressure transmission medium side length of 10 mm, a secondary WC-Co cemented carbide cube cut Angle side length of 4mm) assembly, select a different confining pressure material and pressure carbide ceilings, wafers, at room temperature using ZnTe high pressure phase pressure on the pressure chamber pressure calibration. The experimental results show that pyrophyllite is a suitable confining material. However, the experimental results did not reach the expected value due to the limitation of the pressure table edge, the self-strength of the wafer, and the low confining pressure of the primary cavity. Final pressure anvil confining pressure enhancement. By combining the mechanics simplified model analysis of the two kinds of pressure chambers, it is found that the confining material and the pre-seal side of the second-stage supercharger together form the sealing edge of the second-stage pressure chamber, which consumes most of the system loading Therefore, in the confining pressure test, no increase of the pressure limit of the second stage 6-8 high pressure hydrostatic unit was observed.
