一、问 题 的 提 出目前我国空分行业已生产和完成技术设计的用于空分设备的透平膨胀机,就其轮径规格而言已达十余种。此数尚不包括用于氦液化设备的小型透平膨胀机及用于特殊场合的大型透平膨胀机。然而透平膨胀机的新产品设计方法却仍处在单配设计阶段,这种状况既费时,而且在一定程度上已影响到产品质量、主要零部件的通用性以及生产效率的提高。那么,如何扩大现有透平膨胀机产品的适应范围及其通用性呢?又如何使用户能方便地选择到所需要的
First, the issue put forward At present, China’s air separation industry has produced and completed the technical design for the air separation plant turboexpander, its wheel diameter specifications has reached more than 10 species. This figure does not include small turboexpander for helium liquefaction equipment and large turboexpander for special occasions. However, the new product design method of turbo-expander is still in single-stage design stage, which is time-consuming and has affected the quality of products, the commonality of main components and the improvement of production efficiency to a certain extent. So, how to expand the adaptability and versatility of the existing turbo-expander products? How to make it easy for users to choose what they need
