汽轮机真空系统严密性研究

Study of Vacuum System Tightness of Steam Turbines

汽轮机真空系统严密性是影响真空的主要原因之一，提高真空系统严密性已成为节能降耗的主要工作，受到广泛重视。本文从真空系统设计、制造、运行等方面，系统分析影响真空严密性的关键原因并提出改进建议。

The vacuum system tightness of steam turbines is one of major causes affecting vacuum.To improve the tightness of vacuum system has become an improtant work in energy-saving and reduction of consumption.This paper systematically analyzes the key causes affecting the tightness of vacuum system in terms of its design,manufacture and operation etc.,and puts forward improvement proposals.
