离心式压缩机广泛地应用在输气管线压缩机站,化学与石油加工装置,制冷分离装置及气源与控制用压缩空气系统中。在各种应用中,安全有效的运转,在很大程度上取决于压缩机的控制水平。为了使压缩机安全运转,要求采用喘振控制系统,以确保其不工作于稳定极限以下。因为喘振控制通常要使已压缩过的气体旁路或放空,所以精确地控制压缩机使其工作尽量接近于稳定极限,是充分利用能量的 Centrifugal compressors are widely used in gas pipeline compressor stations, chemical and petroleum processing units, refrigeration separation units, and compressed air systems for gas source and control. In a variety of applications, safe and efficient operation depends to a large extent on the level of control of the compressor. In order to operate the compressor safely, a surge control system is required to ensure that it does not operate below the stability limit. Since surge control usually bypassed or vented compressed gas, precisely controlling the compressor to work as close as possible to its steady-state limit is a function of energy
