Embodiment

[0135] Taking the basic data of a certain equipment of a certain production line as an example, the reliability maintenance evaluation method based on fuzzy comprehensive evaluation of the present invention will be introduced below.

[0136] (1) Determine the implementation scope of reliability maintenance assessment

[0137] After analysis by the reliability maintenance assessment team, it is determined that the object of this assessment is the liquid sulfur product pump of a certain device, and at the same time, the level of failure mode analysis is set as the equipment level.

[0138] (2) Collection and arrangement of basic data

[0139] The content of reliability maintenance evaluation data collection generally includes product overview, operation status, fault information, maintenance information, cost information and the above information of similar products. The data collected this time are shown in Table 3.

[0140] Table 3 basic data information table

Abstract

The invention discloses a reliability-based maintenance evaluation method comprising steps of a fault mode and fault cause analysis, a fuzzy fault influence analysis, equipment maintenance level determination, and maintenance mode determination. According to the evaluation method and system, a proper equipment maintenance strategy can be formulated based on an equipment maintenance level, so that the maintenance cost can be lowered, secure and reliable operation of enterprise production can be guaranteed; and the requirement of modern enterprise equipment management can be met.

Description

technical field [0001] The invention relates to a maintenance evaluation method, in particular to a reliability-based evaluation method, and belongs to the technical field of risk management of petrochemical industry. Background technique [0002] In order to meet the growing demand for domestic energy, the production scale of domestic petroleum and petrochemical enterprises has been continuously expanded, and the production technology has been continuously improved, making the equipment increasingly large, continuous and automated, and the structure of the equipment is also more complex. The maintenance cost and production loss caused by equipment failure have accounted for 30% to 40% of the total production cost of enterprises. Some industries have already ranked second or even higher in the total cost of production. According to statistics, my country's annual expenditure on equipment maintenance alone is as high as more than 80 billion yuan, accounting for 7% to 9% of m...
