摘要
核聚变领域和高能物理等领域内的大型科学装置的迅猛发展,促进了 1.8 K/2 K超流氦系统的进步和广泛应用.作为获取超流氦的常用方法,介绍了 1.8 K超流氦系统中常温减压泵机组的工艺流程、结构、设计参数、自动控制流程、远程监控的设计以及启动停机过程的性能测试验证.通过常温减压泵机组的逐步减压控制,快速且稳定地获取了1.8 K超流氦,泵组各实测参数均达到或优于设计参数.
Abstract
The rapid development of large-scale scientific devices in the fields of nuclear fusion and high-energy physics has promoted the progress and widespread application of 1.8 K/2 K superfluid helium systems.The room temperature decom-pression method is a common method to obtain superfluid helium.The process flow,structure,design parameters,automatic control process,remote monitoring design,start-up and shutdown process and performance test and verification of the warm compressed pump unit in the 1.8 K superfluid helium system were introduced.Through the gradual pressure reduction con-trol of the warm compressed pump unit,1.8 K superfluid helium was obtained quickly and stably,and all measured parame-ters of the pump unit reached or exceeded the design parameters.
