[Abstract]:The technology of equipment condition monitoring and fault diagnosis is a new type of application technology, which is developed in modern times and intersected by many subjects. Its application in industrial enterprises of our country can promote the reform of maintenance system in enterprises, and develop to a more reasonable predictive maintenance system based on condition monitoring and fault diagnosis technology, thus reducing the incidence of accidents. It is necessary to reduce the maintenance cost, ensure the long-term safe operation of the equipment, improve the management level of the equipment, promote the technological progress and increase the economic benefit of the enterprise. It has broad application prospect. According to the present situation of equipment maintenance system in Tianshan Iron and Steel Company, a condition monitoring system and a predictive maintenance system based on fault diagnosis are established. Based on the understanding of the development of fault diagnosis technology at home and abroad, and on the basis of fully expounding the fault diagnosis technology and the theory of predictive maintenance, this paper introduces the technological characteristics of Tiangang equipment, and analyzes the problems and causes in the management of Tiangang equipment. The necessity of carrying out predictive maintenance in Tiangang is discussed. The main research work is as follows: (1) the common parameter indexes and treatment methods of fault diagnosis technology in time domain and frequency domain are analyzed. By summarizing the common faults of Tiangang equipment, the causes and possible harm of fault are discussed. The phenomena and characteristics of typical faults are explained, and the calculation method is given. (2) according to the actual needs of Tiangang, through studying the fault diagnosis mode of the equipment, we can reasonably select the equipment monitoring and diagnosis system Fang charm, The predictive maintenance model of Tianshan Iron and Steel Co., Ltd is established. (3) by discussing the implementation process of predictive maintenance based on spot inspection in Tianshan Iron and Steel Company, the basic work and implementation steps of spot checking and fixing repair system are explained in detail. And through the inspection of spot inspection to promote the optimization process of spot inspection. (4) by discussing the development process of status monitoring and diagnosis technology in Tiangang, the contents and steps of implementing equipment monitoring and fault diagnosis are explained concretely. And the basic work carried out by Tianshan Iron and Steel Company (5) by analyzing the example of fault diagnosis, the paper discusses the routine inspection of operation and maintenance personnel, Based on the rationality and effectiveness of the monitoring mode of equipment running state, which combines professional spot inspection with technical precision inspection, a predictive maintenance system based on spot inspection and fault diagnosis for Tiangang equipment is established. The paper solves the problem that Tiangang used to rely on subjective decision to carry out periodic maintenance. The equipment maintenance cycle is short, the maintenance cost is high, and sudden accidents are easy to occur in production. Through the condition monitoring and fault diagnosis of the equipment, Tiangang reduces the maintenance cost, ensures the safe operation of the equipment, improves the equipment management level, and plays the most solid support for the enterprises to participate in the market competition actively.
