Vibration Monitoring and Fault Analysis System is a high-tech product that integrates sensor technics, signal processing, computer application, expert system and neural networks. It is mainly used in large mechinacal devices in the power, petrochemical, metallurgy, oil refining, steel, and other industrial fields, such as steam turbine generator group, water turbine generator group, compressors, gas turbines, fans, motors, pumps, gear and the rolling bearing etc, it can serve as a rigorous analysis of vibration monitoring system for the devices. By continuous monitoring equipment operating parameters of the important, it will be able to timely understand of the operating conditions of the equipment, to provide important data for the prediction of incoming accidents, make a fast analysis for the fault that has occourred, quickly find out the cause of the fault, and remind operating personnel to take the necessary measures, it can provide a reliable protection for the safe operation of the equipment.
