Big-scale Turbine-compressor Sets Failure Diagnosis And Maintenance System

For improving the safety of the set using, these days, the state monitor of the large rotor machinery have been adopted in large. Following the development of the regular and the condition maintenance of equipment, the technology of the trouble diagnosis of equipments has been thought highly of, and developed go on. Following the development of the technology of communication and network, beside the technology of single set, people hope the technology of the maintenance could share, so that could solve more set trouble, so it is an inevitable trend for the diagnosis technology that network should be connected.USA, Japan, the developed countries in Europe have unfolded the prescience maintenance for the large sets broadly, namely state monitor maintenance, it can save 30-50% maintenance cost, and it can make running cycle of the equipment extend. In the recent 20 years, some large corporations cooperated with famous universities and science departments, they manufactured the systems of monitor and trouble diagnosis of the large running equipments fit themselves, but some of these systems have some weakness, such as analysis speed is slow, it lack the comprehensive analysis ability in the monitor engineering signal collected, it hasn't good interchangeable and extensible capability, it isn't good in precise analysis diagnosis professionally.So, it is necessary to admit the advantages of the monitor diagnosis analysis systems from the abroad and the civil develop and manufacture the monitor diagnosis system with recent and advanced technology. This system could change the old way patrol, make the equipment monitor timely and effectively, it could save not only the time and personnel work, but also the time of the maintenance of equipment, it could achieve the purpose that reduce the consumption and save cost and improve the efficiency of equipment using and procreation, at the same time it provide the scientific foundation of the management of the equipment and procreation.The large turbine compressor is the "heart" of all unit of Daqing Petroleum Chemical Corporation, it exerts the great function during the corporation procreation, this kind of important equipments running in the surroundings of high temperature, high pressure, high running speed, strong erosion, inflammable, explosive and so on, so the accidents like bearing burned, serious wear, impeller burst, vane crack occurred many times. For the reason that petroleum chemical corporations always running automatically and continually, these large sets once occurred trouble, it would make chain reaction, it would make great economic loss. Therefore it is the problem need to solve urgently on how to improve the management of the large sets and ensure the large sets running safely and reliably.Large turbine compressor trouble diagnosis and maintenance making policy assistant system is a distributed network system face to whole enterprise, it connects the large turbine compressors with the net. The system can not only monitor and diagnose trouble on line about these sets running state, but also provide the basic state and the ability of maintenance situation message, it conjoins the vibration data and technical parameter and present regular monitor message, it realizes the regular assessment in common running condition of the sets and the comprehensive trouble diagnosis analysis in unusual running condition, it provides important foundation for maintenance and the sets trouble found earlier. It changes the old way in patrol and maintenance of important sets basically, and improves the level of equipments management.
