Detailed Description

The degradation of the equipment refers to the phenomenon that the operation efficiency of the equipment is gradually reduced due to the abrasion, fatigue or deformation, corrosion, aging and other reasons of the parts in the use process. Degradation conditions inevitably occur during use of the device. The equipment degradation reduces the operation efficiency of the equipment, and further gradually increases the energy consumption of the production enterprises. In order to cope with the equipment degradation, analysis of changes in the equipment degradation condition, i.e., the operation efficiency, is becoming an issue.
The treatment scheme to be adopted is also different for different equipment degradation conditions. Because of the different actual structures, the operating efficiency varies to different extents between the various devices, and often cannot be described by a single data or factor
Existing analysis of plant operating efficiency is typically based on plant reliability considerations, where limits for safe operation are derived based on fatigue limits for certain materials or components, while systematically less specific functional relationships are derived for plant operating efficiency and its related parameters (time, cumulative load, etc.). The analysis of the operating efficiency of the equipment generally aims at the whole equipment, the granularity is thicker, and the conclusion is more general. Meanwhile, when the difference caused by overhaul and maintenance occurs to the components affecting the operation efficiency of the equipment, the original operation efficiency analysis accuracy is also reduced.

The parallel connection relationship refers to that in the working process of the equipment, a plurality of constituent units jointly complete a task, and then the relationship of the two constituent units is regarded as parallel connection. For example, in the case of a tire component on an automobile, when a plurality of tires together fulfill the task of providing friction to the ground to drive the automobile, the tire constituent units are in parallel connection when the tires are divided into different constituent units.
103. An operational efficiency expression of the plurality of constituent units is obtained.

obtaining a recovery coefficient of maintenance behavior on the operation efficiency, wherein the recovery coefficient is multiplied by the operation efficiency before maintenance is equal to the operation efficiency after maintenance, or the recovery coefficient and the operation efficiency before maintenance are added to be equal to the operation efficiency after maintenance;
obtaining an overhaul plan, wherein the overhaul plan comprises different overhaul behaviors applied to the equipment and conditions for implementing the overhaul behaviors;
and correcting the operation efficiency change curve by using the maintenance plan and the maintenance behavior to recover the operation efficiency.
4. An apparatus for generating an expression of operation efficiency of an apparatus, comprising:
a processor, a memory, a bus, and an input/output device;
the processor is connected with the memory and the input and output equipment;
the bus is respectively connected with the processor, the memory and the input and output equipment;
the processor being adapted to perform the method of any one of claims 1 to 2.
5. A computer readable storage medium storing instructions which, when run on a computer, cause the computer to perform the method of any one of claims 1 to 2.
