Abstract

Abstract: Due to diversification of technical development of steam turbine seal, when a power plant try reform its steam turbine for energy conservation, it is faced with a question: how to select various seals. According to the characteristics of the radial motion of turbine shaft under various conditions, the variation laws of seal safety gap and economical gap of steam turbine in two conditions were analyzed, and the classifying method of various gland seal was proposed, which provides more scientific and rational reference standard and basic principle for steam turbine seal reformation in power plants.

Key words: steam turbine, classification of gland seal, type selection, combination, standardization
