看看这句话如何翻译? This verification test is very complicate and time consuming for multistage integrally geared compressors as each stage has to be dismantled stepwise in order to attach the test unbalance weights. At smaller wheels the test weights cannot be attached properly. Based on ACE’s experiences the resonance speed or speeds can be analysed with the residual unbalances with sufficient accuracy and compared with the calculated ones. Results for similar compressor units may be discussed in advance查看更多2个回答 . 5人已关注
