摘要:
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，将大流量稳压技术应用到氢吹系统的设计当中去，并顺利地完成了试验。试验结果表明：基于这种高压大流量稳压技术的氢吹系统设计是合理、可靠的，同时为后续高压大流量试验提供了更好的技术支持和实践基础。
Abstract:
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, were analyzed to insure its rationality and stability. This technology was used for the design of hydrogen blowing system. And the tests were accomplished successfully. The test results show that the hydrogen blowing system based on the large flow steady pressure technology is reasonable and reliable. The study provides a better technical support and practical foundation for the follow-up engine test.
