Résumé

Centrifugal compressors are wildly used in many process industries. The stability is one of the most important characters of centrifugal compressor. When the compressor operates in the condition of small volume flow rate, the working conditions of rotating stall and surge will occur, which leads to the unstable condition for centrifugal compressor. The signals of compressor are tested and analyzed when surge condition occurs in this paper. In addition, a new method to improve the compressor stability is proposed. It is called the active control casing treatment (ACCT) system. The flow in the compressor impeller is changed by the ACCT system and the stability of compressor is improved. The experimental researches have been done in this paper. The test results of ACCT system are also discussed in this paper.
