高压大流量氢气稳压技术在试验中的研究与应用

氢涡轮泵介质试验较以往试验有了很大的变化，尤其是高压大流量氢气介质试验工况的出现。于是，相应的试验技术需要改进和突破。文章涉及的大流量稳压技术是解决上述问题的有效途径，通过对大流量稳压技术中的关键问题（减压器并联稳定性以及临界流文丘里喷嘴氢气流量控制的准确性）的细致研究，确保了该项技术的合理性与稳定性。最后，将大流量稳...

Application of steady pressure technology of high-pressure large-flow hydrogen in test

By contrast with the other tests,the medium tests have changed a lot,especially for the appearance of working condition of the high-pressure and large-flow hydrogen.So,the corresponding test techniques need to be improved.The large-flow steady pressure technology involved in this paper is an effective way to solve such problems.The key technology issues of regulating large flow,including the stability of pressure reducers in parallel and the controling accuracy of the critical gas flow in Venturi nozzle,wer...
