合缸机组高中压轴封漏量测量方法的探讨

Renovation of Measuring Method on Steam Leakage in the Front Gland of HP&IP Cylinder

介绍了高中压合缸机组高中压缸前轴封由于结构的原因而无法直接测量其漏量,采用影响系数法确定其漏量的试验计算方法。计算分析表明,准确地确定其漏量对确保试验精度、经济性的准确分析具有重要意义。

The article introduced a calculation method on steam quantity leakage in the front gland of HP＆IP cylinder which can＇t get through direct measuring since the front gland structure of combined cylinder turbine. The leakage quantity will be determined by influence coefficient method. The anlysis on calculation indicates the determination of the gland leakage plays important role on ensuring the experiment accuracy and exact economic analysis.
