【摘要】 通过现场测试 ,研究了国产 30 0MW汽轮机在运行过程中低压缸和低压轴承标高的动态变化规律。研究结果表明 ,真空和排汽温度是影响低压缸和低压轴承动态标高的主要因素。真空和排汽温度越高 ,轴承标高降低得越多。该型机组低压缸和低压轴承的标高变化规律基本一致更多还原

【Abstract】 Through tests in the field, the dynamic elevation changing regularity of low pressure (LP) cydinder and LP bearings in operation course of a 300MW steam turbine has been studied.Results of Study show that the vacuum and exhaust steam temperature are main factors influencing upon the dynamic elevation of LP cylinder and LP bearings of said unit.The higher the vacuum is, the more the evelation lowers; the higher the exhaust steam temperature is, the more the elevation lowers. The elevation changing regularity of LP cylinder and LP bearings of this type units is basically consistent.更多还原
