Rotary machinery vibration integrated management system

Abstract

The invention relates to a rotary machinery vibration integrated management system comprising a data acquisition module used for acquiring vibration signals, thermodynamic system parameters and structure parameters of a rotary machinery; the state monitoring module is used for monitoring whether the vibration is abnormal; the comparative analysis module is used for storing historical vibration data; the fault diagnosis module is used for diagnosing the fault type of the abnormal vibration signal; the dynamic balance management module is used for calculating weighted mass and angle; the maintenance management module is used for storing abnormal maintenance work content; the report management module is used for generating a vibration fault condition report; the case management module is used for recording correctly diagnosed vibration events; the vibration standard query module is used for storing the vibration standard of the rotary machine; and the twenty-five anti-measure module is used for storing twenty-five anti-measure contents. Compared with the prior art, integration of vibration monitoring, fault processing and information management of the rotating machinery is realized, and the safety of the rotating equipment and the comprehensive management level of a power plant are improved.

Description

technical field [0001] The invention relates to the field of rotating machinery systems, in particular to a comprehensive vibration management system for rotating machinery. Background technique [0002] Rotating equipment is one of the most important equipment in power generation enterprises, such as steam turbines, generators, six major fans and various pumps, etc. Whether it can operate safely and stably affects the safety and economy of the entire generating set. For rotating equipment, vibration failure is the most important equipment failure, so it is particularly important for the monitoring of vibration signals of rotating machinery in power generation enterprises, the diagnosis and treatment of vibration failures, and the management of vibration information. [0003] The monitoring of vibration signals of rotating machinery, the diagnosis and treatment of vibration faults, and the management of vibration information are three important components of the comprehensiv...

Problems solved by technology

[0003] The monitoring of vibration signals of rotating machinery, the diagnosis and treatment of vibration faults, and the management of vibration information are three important components of the comprehensive management of vibration of rotating machinery. If any part of the work is not in place, it will not be conducive to the comprehensive management of vibration and affect the safety of the unit.

Real-time monitoring of rotating machinery vibration is necessary, but because some equipment does not have monitoring equipment or monitoring methods are not in place, abnormal vibration signals are not captured, which may eventually cause vibration failures and affect the safety of the unit; for rotating machinery vibration fault diagnosis, professional High security requirements, when a vibration fault occurs, due to the failure to analyze and deal with the problem in time, it may cause greater safety accidents and economic losses; for the management of vibration information, due to the large number of rotating equipment in the generator set and the rotating equipment in operation Vibration signals are transmitted all the time, and the amount of information is large. Every fixed period, the vibration data in the monitoring and control equipment of the power plant will be automatically deleted, which is not conducive to the later vibration analysis
