摘要: 主要介绍了超高压氦增压系统的工作原理、设计原则和加工方法，讨论了各功能部件的选择与高压密封设计，同时指出了在使用超高压氦增压系统时应当注意的问题。在系统建成后，通过手动、自动控制分步增压和保压实现了最高300 MPa的超高压氦气输出，相应的高压漏率达到(3.5～5.0)×10-7 Pa·m3/s。对系统主要性能参数进行了考核，并将其与3种同类增压装置的相应参数进行了比较，结果表明该系统设计合理、性能优越并且安全可靠。该系统将主要应用于惯性约束微球靶充氘氚系统的各项性能测试。Abstract: Operation principle, design principle, fabrication and cautions in operation of ultrahigh pressure He booster system are introduced, and main parts selection method and high pressure seal design of the booster system are discussed. The asdeveloped system can output 300 MPa helium gas with (3.5～5.0)×1010-7 Pa·m3//s leak rate through manual or automatic pressure boosting and keeping. Main function parameters of the system are accessed and compared with those of three congeneric systems. The result shows that the system was rationally designed with superior performance and safety, and the system would be used to test ICF microsphere filling DT system.
