M701F机组高压旁路调门不能关闭的原因分析

Analysis on reasons causing high-pressure bypass governor valve of M701F unit to be unable to close

通过结合三菱燃气-蒸汽联合循环机组旁路逻辑动作行为,论述了M701F机组在启机过程中高压旁路调门不能正常关闭的问题。针对这些问题进行了分析,提出了解决措施,以避免出现类似的问题。

Combining with the bypass logic action behavior of the Mitsubishi gas-steam combined cycle unit,the problem of the high-pressure bypass governor valve of the M701F unit,which could not be closed normally during the unit start-up process,was expounded.The problems were analyzed.The solution was given,and similar trouble was avoided.
