Research of a New Reliability Analysis Method Based on Multilevel Flow Model and Its Application on the Gas Turbine Compressor

Abstract

In long-distance pipelines, the Gas-Turbine-Driven Compressor Unit is the essential power equipment to ensure gas transmission smoothly. Therefore, reliability analysis must be carried out on a regular basis. However, thus far, an accepted analysis system has not been established concerning the Gas-Turbine-Driven Compressor Unit, and a complex system could not be analyzed through the existing methods. Therefore, the present paper proposes a reliability analysis method based on Multilevel Flow Model (MFM-RA). MFM-RA not only clearly reveals a research object’s goals, functions, components and interactive relations, but also is able to calculate the reliability index of the research object and each subsystem. The reliability analysis method, proven to be effective for mechanical systems with complexity, is applied to the lubricating oil system of the compressor unit.
