引言我厂生产的第一台20万瓩汽轮机1972年在朝阳电厂投运已来已近八年了,随后又有三台机组陆续投运。机组从设计、试制、成批生产直到电厂运行,为社会主义建设发光发热,这说明成绩是主要的。但是,电厂的运行实践证明尚有许多问题急待解决,这就要求我们为使20万机组的不断完善而努力。该机组高压调节伐运行不稳定,振动很大,致使伐杆经常断裂。据统计去年一年已投运的20万机组总计共发生了60起重大事故,而其中伐杆断裂事故就发生了27起,占重
Introduction The first 200,000 tons turbine produced by our factory has been put into operation for about eight years in Chaoyang Power Plant in 1972, and then three units have been put into operation one after another. From the design, trial production, mass production until the power plant operation, for the construction of socialism glowing, indicating that the results are the main. However, the operation of power plants proved that there are still many problems to be solved urgently, which requires us to make 200,000 units continue to improve and work. The unit high-pressure regulation of cutting instability, vibration, resulting in the cutting bar often rupture. According to statistics, a total of 200 major accidents have occurred in 200,000 units put into operation last year, of which 27 occurred in the case of cutting bar breakage,
