摘要
隔板汽封漏汽量对汽轮机的相对内效率产生较大的影响,目前各种隔板汽封漏汽量的计算公式形式上存在较大的差异。从理论上深入地分析了几种常用隔板汽封漏汽量计算公式之间的异同以及各自的适用条件,给出了适合于计算隔板汽封漏汽量的通用计算公式。举例对各种计算公式的计算结果进行了分析。
The steam leakage of diaphragm gland influences on relative internal efficiency of steam turbine greatly.There are larger formal differences between current steam leakage calculation formulas for various diaphragm glands.The differences and the similarities of several frequently-used steam leakage calculation formulas for various diaphragm glands and the applicable conditions for each formula were theoretically analyzed in depth;and a general formula of steam leakage calculation for diaphragm glands was given.Based on practical examples,the calculation results of various calculating formulas were analyzed.
