Overhaul management system and service life management method for important compressor parts in coal chemical industry

Abstract

The invention relates to an overhaul management system and a service life management method for important compressor parts in a coal chemical industry, which can be used for the equipment management of multiple compressor sets in the coal chemical industry enterprises and belong to the technical fields of chemical engineering and compressors. The overhaul management system is characterized by comprising data management software, a computation / application server, a database server, an external system interface, a compressor data acquisition system, a parameter measuring point and a user side browser. The service life on-line management method is characterized by comprising the following steps of: operating the service life analysis software of the important compressor parts in the coal chemical industry, which is complied with C language, on the database server; calculating the accumulated low cycle fatigue service life loss and accumulated torsional vibration fatigue service life loss of the important compressor parts on line; and guiding the optimized operation and the active overhaul measure of the multiple compressor sets. The invention has the advantages that one set of active state overhaul management system manages the service life of the important parts of a plurality of compressors and the technical effect of active state overhaul is realized.

Description

technical field [0001] The invention relates to an overhaul management system and life management method for important components of coal chemical compressors, which are applied to the equipment management of multiple compressor units in coal chemical enterprises and belong to the technical fields of chemical engineering and compressors. Background technique [0002] The important parts of the compressor refer to the expensive and seriously damaged parts, mainly including: crankshaft, bearings, rotors, pistons, and sealing components. The start-up process, shutdown process, and load change process of the compressor are called unsteady-state operation processes. During the unsteady operation of the compressor, it is easy to cause a large loss of life to the important parts of the compressor. Improper operation of the compressor can shorten the life of the important components of the compressor. As the running time of the compressor increases, the cumulative loss of the impo...

Problems solved by technology

At present, the mainstream scheme of equipment maintenance in the world has been replaced by the active condition maintenance scheme. Although the maintenance strategy has gradually begun to change in China, there are still many different understandings and deficiencies in the existing condition maintenance scheme of equipment in China: 1. It is the lack of research on the overall strategy of condition-based maintenance, over-reliance on online monitoring technology, and the application of online monitoring devices to measure the depth of condition-based maintenance application research; the second is the lack of scientific assessment methods for grasping the current health status and future development trends of equipment. The health assessment is still limited to the simple qualification of the original preventive test standards; the third is the lack of comprehensive statistical analysis software for various data of state-of-the-art maintenance
