en.Wedoany.com Reported - At 16:20 on April 16, another achievement was reported from the Huainan Luohe Power Plant Phase IV 2×1000MW ultra-supercritical double reheat coal-fired power project, constructed by China Energy Engineering Group Construction Co., Ltd. The high-pressure cylinder of Unit 7 was precisely and smoothly installed. Following the recent "two major components in one day" hoisting of the stator and intermediate-pressure cylinder, this efficient completion of another critical milestone has laid a solid foundation for the full-scale installation of the turbine body.
The high-pressure cylinder hoisted this time measures 6.4 meters in length, 3.9 meters in width, and 4.55 meters in height, with a total weight of 170 tons. To ensure a flawless hoisting operation, the project team planned meticulously in advance. Leveraging the mature technical system used for the stator and intermediate-pressure cylinder hoisting, they employed a combined hoisting system consisting of two 180-ton cranes rigidly coupled and synchronized with four 200-ton hydraulic lifting devices. Full preparatory work, including pre-tensioning of steel strands, hoisting tool calibration, crane deflection monitoring, and load tests, was completed beforehand. Furthermore, joint pre-hoisting condition acceptance and briefing sessions were conducted with the owner, supervisor, and general contractor to clarify key process points, risk prevention and control measures, and emergency response plans, ensuring all hoisting conditions were comprehensively met at once.
During the hoisting operation, the site implemented unified command, dedicated personnel supervision, and closed-loop control throughout the entire process. Technical standards and safety regulations were strictly followed, executing key procedures such as lifting, suspension tests, translation, and precise placement in sequence. Through standardized operations, the high-pressure cylinder was installed steadily and accurately. All monitoring indicators fully complied with the construction and acceptance specifications, marking the successful completion of the hoisting task.
The successful installation of the high-pressure cylinder is another significant achievement following the "two major components in one day" hoisting of the stator and intermediate-pressure cylinder. It fully demonstrates the project team's professional capabilities and pragmatic work style in scientific planning, meticulous control, and collaborative operations. Moving forward, the project team will build on this momentum, closely monitor all construction milestones, strictly adhere to safety and quality standards, and efficiently advance the subsequent installation of core equipment and system commissioning. They are committed to building a green, efficient, high-quality, and exemplary coal-fired power project.
