此次修订改动内容：

1、第7页：高中压内缸中分面间隙允差：自由状态下2mm以下冷紧1/3螺栓后，0.05M寒尺不入：

低压内缸中分面间隙允差，自由状态下2mm以下，冷紧1/3螺栓后0.05mm塞尺不入。

2、第15页：#3、的轴承均应布置在同•条水平轴线上。用轴承应高出该线1.489mm,#2轴承应高

于该线0.329m。要求高中压转子比低压转子对轮端面低0.10-0.15,下张口O.Olnm。（备注：

根据2014年#2机组大修调整，#3、#4轴承均应布置在同一条水平轴线上。#1轴承应高出该线

1.489m,#2轴承应高于该线0.329mm。要求高中压转子比低压转子对轮端面低0.10-0.15,下

张口0.20mmo）

3、第15页：低压转子要比发电机转子对轮端面高0.10-0.Mnm,下张口0.01-0.02m”现改为低发

电机联轴器找中心时，发电机转子要比低压传子对轮端面高0.10-0.Mmm，下张口0.01-0.02mm。

4、第120页，定冷水系统展加定冷水加药装置.并将原在进入发电机前.约2曲地定子水旁跖进入

离子交换器，连续进行水质净化。改为：在进入发电机前，约20%地定子水旁路进入（定冷水加药装置，

将原来的离子交换器进行短接，连续进行水质净化。

5、第144页：增加6.1.1.5除氧器乏汽回收装置，将原除氧器连续排气直接通过之汽回收装置进行

冷凝回收，回收的水质直接进入凝汽器，充分利用水资源，起到节约用水的效果。

前言

本规程根据《国家电网公司电力安全工作规程》、《火电检修规程》、《火电施工质量桧验及评定标准人

《桧修导则小设备制造厂家的设计掘粮、技术说明书、安装T艺说明、运行操作说明、图纸及其它相

关资料，已经投入运行的同类设备的检修规程、技术及质量标准、设备运行经腌，同类设备运行中存在

问即的处理方案等等编制而成。

设备管理人员和检修人员应严格依照检修规程规定的检修周期、检修工序、检修工艺质量标准和检

修试验规程等制定检修计划，并依据检修规程和检修文件包管理标准的要求编制并执行检修文件包、作

业卡、施工方案等作业文件。

本规程由于定稿之际，17部分设备技术资料不全，故本规程与实际不符之处尚待送•步修改补充，

如发现本规程不妥之处，敬请及时指出。
