摘要目前国内外电站汽轮机大多采用的是梳齿型汽封,文中着重研究此种汽封的漏汽问题,应用了马丁公式作为主要研究方法,进行理论推算的同时并进行试验修正,最终推导出可供设计参考的经验公式,以此公式为依据可以比较准确地计算出汽封漏汽量。 At present, comb-type steam seal is mostly used in domestic and international power plant steam turbine. This paper applies Martin formula as the main methods to research the steam seal leakage. The theoretical calculations and experimental correction are used to derive the empirical formula for design. Based on this formula, the steam seal leakage can be calculated more accurately.
