On-line Condition Monitoring And Fault Diagnosis Is System For Larger Rotary Machinery

As a means of solving engineering vibration problems, vibration testing and analysis technique has been used for many years. In the past twenty years, with the development of science and technology, vibration testing and analysis technique has changed a lot not only in theory but also in application. After coming into 70's, microcomputers have been used more and more popular, especially FFT algorithm introduced, which made vibration testing and analysis technique enter a new stage.The condition monitoring and fault diagnosis system for larger rotary machinery is applied to all kinds of larger rotary machinery such as Stirling engine. The condition monitoring and fault diagnosis system can give the causes of all faults and abnormalities and also gives the opposite measures by getting the condition parameters of machineries in the past or nowadays. The system is vibration signal processing system in windows. It has the functions of collecting vibration signal power spectruiru cepstrum and transfer function analysis and so on with the PCL₁800. At the same time, the system can convert the data into the corresponding graph. This book introduces detailedly this system's components and their functions. It can be used largely in the fields of electrical system, oil and chemistry company, refine industry, automobile and the ship manufacturing etc for testing and analyzing of the vibration signals.This system software is programmed with the advanced programming language Visual C++ and runs in the window system. The design of the software interface can meet the demands of most users. The interface is friendly and popular common.
