  1. At present, surge control method for centrifugal compressor being used is commonly by least - flow method. it can ’ t make compressor working within operating condition area, sometimes starts the surge control system earlier, which will waste energy sources and depress economy benefit. even, its control system commonly consists of simulation instrument, can ’ t modify the changing surge curve of compressor in time and can ’ t control nonlinear surge curve preferably

    目前，在用的離心壓縮機的防喘振方法一般採用最小流量法，它不能充分使壓縮機工作在其工況區，往往過早起動防喘振系統，浪費了能源，降低了經濟效益。且控制系統一般採用模擬儀表構成，在壓縮機的喘振線發生變化時不能及時修正，對非線性的喘振線不能較好的實施控制。
  2. Cracking failure of centrifugal compressor ' s impellers was analyzed, the welding craters in the impellers led to stress concentration. the unsteady gas flow accelerated the development of cracks in the impeller

    摘要針對某石化公司離心壓縮機葉輪多次發生開裂、掉塊等故障以及裂紋形成機理進行了分析。分析結果表明了葉輪開裂原因系疲勞開裂，葉輪焊接缺陷產生了焊接弧坑，造成表面應力集中，氣流激振加速了裂紋擴展。
  3. An optimization design system has been constructed and practically used for centrifugal compressor components and mixed - flow pump impeller
