摘要
Abstract
A mathematic model was established for estimating the maximum entropy spectrum of the rotary shaft of a centrifugal water injection pump, and the maximum entropy spectrum curve was obtained. The fault types and causes of the pump in running can precisely be judged according to the curve. The corresponding fault diagnosis software and system were also designed. This method can eleminate the influences of energy leakage, window function, palisade effect and etc. On the diagnosis results in traditional entropy spectrum analysis method. Some examples illustrated that the diagnosed results by the method are identical with the real conditions of centrifugal pumps.关键词
