本工程汽轮机为哈尔滨电机厂有限责任公司生产，C350/317-24.6/0.4/569/569型汽轮机，超临界、一次中间再热、三缸两排汽、单轴、间接空冷抽汽凝汽式机组。为确保1、2号机组汽轮机扣缸工作顺利进行，西南热电公司超前策划、周密部署，各参建单位密切配合、团结协作，组织优化汽轮机扣盖方案，全体作业人员进行安全技术交底，确保各个环节安全、高效、有序进行。

9时36分1号机组汽轮机低压缸部件第一钩起吊，23点58分2号机组低压外缸落下，两台机组汽轮机扣缸工作顺利完成。整个汽机扣缸过程中，建设单位、总包、监理、施工单位专业人员全程旁站，严格对汽轮机扣缸过程中的工艺及质量点进行见证验收，整个扣缸过程中各技术参数准确无误。

1、2号机组汽轮机扣缸工作的顺利完成，标志着两台机组汽轮机本体安装工作向前迈进一大步，为按期高质量投产赢得了宝贵的时间。下一步，西南热电公司将继续从严从细做好后续机组安装中安全及质量管控，以“高水平达标投产”为契机，全力以赴、攻坚克难、奋勇争先，为打造全国首台套风光火储多能互补一体化电力优质工程而努力奋斗。

The steam turbine in this project is a type C350/317-24.6/0.4/569/569 steam turbine produced by Harbin Electric Machinery Factory Co., LTD. It is supercritical, one intermediate reheating, three cylinder and two row steam, single shaft, indirect air cooling extraction condensing unit. In order to ensure the smooth progress of turbine cylinder work of Unit 1 and 2, Southwest Thermal Power Company has advanced planning and thorough deployment, and the participating units have cooperated closely and cooperated in unity to organize and optimize the turbine lid plan, and all operators have carried out safety and technical communication to ensure that all links are safe, efficient and orderly.

At 9:36, the first hook of the low-pressure cylinder of the steam turbine of Unit 1 was lifted, and the low-pressure outer cylinder of Unit 2 fell at 23:58, and the steam turbine cylinder of the two units was successfully completed. During the whole process of cylinder docking, the construction unit, the general contractor, the supervisor and the professional staff of the construction unit stood by the whole process to strictly witness and accept the process and quality points of the turbine cylinder docking process, and the technical parameters in the whole process of cylinder docking are accurate.

The successful completion of turbine cylinder work of Units 1 and 2 marked a big step forward in the installation of turbine bodies of the two units, and won valuable time for high-quality production on schedule. In the next step, Southwest Thermal Power Company will continue to strictly and carefully do a good job in the safety and quality control of the follow-up unit installation, take the opportunity of "high level of standard production", go all out, overcome difficulties, and strive to create the country's first set of wind and fire storage multi-energy complementary integrated power quality project and strive.
