Service Life predicting method for machine and vulnerable component of generating set

Abstract

The invention relates to a method for estimating the life of the mechanical wearing parts for the power set, which comprises: counting the history data of the life of the mechanical and electrical wearing parts, setting up a life database of the mechanical and electrical wearing parts, determining the distribution category and parameters of the mechanical and electrical wearing parts, counting the reliability R(t) of the mechanical and electrical wearing parts, counting the reliable life tR0 of the mechanical and electrical wearing parts, setting up a knowledge base of the malfunction result of the mechanical and electrical wearing parts, determining the changeover period HRP of the mechanical and electrical wearing parts, estimating the residual life HRL, adjusting the planned maintenance interval to realize the optimized maintenance. The advantages of the invention are that the changeover period of the mechanical and electrical wearing parts can be calculated quantitatively in the using stage of the power set, and the residual life of the parts can be calculated quantitatively, thereby a computer online monitor of the changeover period and the residual life of the mechanical and electrical wearing parts can be realized.

Description

technical field [0001] The invention relates to a life prediction method of mechanical vulnerable parts of a generating set, which is applied to the replacement and maintenance of the mechanical wearing parts of the generating set, and belongs to the technical field of power generation engineering and generating sets. Background technique [0002] The mechanical equipment of the generator set has a large number of mechanical wearing parts. The mechanical wearing parts refer to the parts that frequently fail in the power plant and are often replaced or repaired in the planned maintenance and accident maintenance. The replacement or maintenance of the mechanical vulnerable parts of the existing generator sets is mostly replaced or repaired in the planned maintenance based on experience, or replaced or repaired after the mechanical vulnerable parts fail. Due to the serious failure consequences of the mechanical wearing parts of some generator sets, it may cause the equipment to...

Problems solved by technology

Replacing or overhauling mechanical wearing parts after failure may cause large economic losses

According to experience, replace or overhaul the mechanical wearing parts in advance during the planned maintenance of the generator set. It is possible to replace them too early and not make full use of the remaining life of these mechanical wearing parts, resulting in waste and economic losses.

At present, there is no suitable method and system available for life prediction and replacement cycle determination of mechanical wearing parts of generator sets
