本文介绍了西安重型机械研究所0.1Torr 水蒸汽喷射泵试验研究所取得的最新成果。通过对真空泵系统的不断完善,以及理论和实践的多次反复,该泵的主要技术经济指标已达到国际上同类泵的先进水平,其蒸汽耗量仅约为国内同类泵的三分之一。下几期还将简要地介绍蒸喷泵带普遍意义的若干关键技术,如泵的优化设计;水蒸汽的湿度测定;汽水分离和加热装置;消音器以及电子计算和的应用等。 This article introduces the latest achievements of the experimental research of 0.1Torr steam jet pump in Xi’an Heavy Machinery Research Institute. Through the continuous improvement of the vacuum pump system, as well as repeated many times of theory and practice, the main technical and economic indexes of the pump have reached the international advanced level of the same kind of pump, and its steam consumption is only about one third of that of similar pumps in China. The next few will also briefly introduce some of the key technologies of steam jet pump with general significance, such as pump optimization design; water vapor humidity determination; steam and water separation and heating device; muffler and electronic calculation and application.
