在各种低压缸设计的基础上形成不同参数和功率的通用化汽轮机系列。为了得到新的功率等级,通常需进行新规格品种低压缸的设计。目前,要扩大冷却条件范围和经常满足特殊的(特别是由于出口的需要)多种工况和工艺的要求,就必须在每一通用化汽轮机系列范围内增加低压缸的规格品种。列宁格勒金属厂汽轮机生产联合公司对K—200—130型汽轮机的最新改型足以说明这一问题
In a variety of low-pressure cylinder design based on the formation of different parameters and power of the universal turbine series. In order to get the new power level, it is usually necessary to design a new type of low-pressure cylinder. Currently, expanding the range of cooling conditions and the need to meet a variety of conditions and processes, often due to special needs due to exporting, necessitate the addition of low pressure cylinder sizes within each range of generalized steam turbines. The latest retrofit of K-200-130 turbines by Leningrad Metal Works Turbine Manufacturing Associates is sufficient to illustrate this issue
