Problems solved by technology

The biggest difficulty in carrying out RCM work is the lack of effective reliability data and maintenance data. The reliability obtained by the traditional RCM method is "static", but in practice these effective data often change dynamically with th

specific Embodiment

[0043] This embodiment is the equipment preventive maintenance plan information management system established by Sinopec Wuhan Branch for more than 2,000 machines and pumps in the whole plant.

[0044] The sources of the basic equipment data used are:

[0045] (1) The equipment account data comes from the EM (Equipment Management) system of Sinopec Corporation;

[0046] (2) The historical inspection and maintenance data of the equipment comes from the EM system of Sinopec Corporation;

[0047] (3) The analysis data of equipment failure intensity is provided by Sinopec Wuhan Branch;

[0048] (4) The equipment operation monitoring data is associated with the equipment monitoring platform of Sinopec Wuhan Branch to provide data access interface.

[0049] Under normal circumstances, there are two measuring points for the state value L of the bearing of the pump equipment, that is, the front end L value and the rear end L value; the vibration value V has five measuring points, na...

Abstract

The invention discloses a preventative device maintenance method based on dynamic reliability and belongs to the technical field of petrochemical equipment management. The preventative device maintenance method based on the dynamic reliability comprises the following steps of 1 establishing a device basic database including equipment accounts, historical maintenance and repair data, a fault strength analysis data, operation monitoring data and the like; 2 utilizing basic data to conduct operation time analysis, fault strength analysis and alarm state and operation trend analysis on devices; 3 utilizing results to establish a device reliability level and fault strength incidence matrix, formulate DRBPM data analysis logic, automatically screen preventative maintenance devices and generate preventative maintenance planning reports of the devices; 4 examining, verifying and executing the preventative maintenance planning reports of the devices. The preventative device maintenance method based on the dynamic reliability can be used for dynamic analysis and management of states of petrochemical equipment, facilitate formulation of scientific and effective device maintenance measures and provide guarantee for timely device fault elimination and production continuity reliability and can be widely applied to the technical field of petrochemical equipment management.

Description

technical field [0001] The invention belongs to the technical field of petrochemical equipment management, and in particular relates to an equipment preventive maintenance method based on dynamic reliability. Background technique [0002] Equipment is the basis for the production and operation of an enterprise, and the quality of equipment management and maintenance directly determines the production capacity and level of the enterprise. Petrochemical plants generally have the characteristics of large-scale, complex and continuous production, and their operational reliability and maintainability are very important. At present, many domestic petrochemical enterprises adopt traditional maintenance methods for production equipment, that is, after-the-fact maintenance and regular maintenance methods. After-the-fact maintenance, also known as faulty or corrective maintenance, is the maintenance performed after the equipment fails or its performance decreases. This "repair as it...
