“囯模扒开”世界首台500兆囯模扒开瓦冲击式水电机组球阀铸钢件在川交付

  中新囯模扒开网德阳11月18日电 (记者 囯模扒开刘忠俊)11月18日,国机重型装备集团股份有限公司(以下简称“国机重装”)研制,世界首台500兆瓦冲击式水电机组球阀铸钢件在四川省德阳市正式交付并起运,该球阀铸钢件是冲击式水电机组核心部件。

  据了解,球阀铸钢件是冲击式水电机组的核心部件,由大瓣阀体、小瓣阀体、活门铸件组成,零件最大重量约90吨,最大轮廓尺寸超过5米,尺寸规格、重量均属于同类型球阀之最。

  世界首台500兆瓦冲击式水电机组球阀铸钢件将应用于国家能源局能源领域首台(套)重大技术装备项目——扎拉水电站500兆瓦冲击式水电机组。这是国机重装为扎拉水电站提供世界首件500兆瓦转轮中心体锻件后,接续努力制造的又一重大技术装备关键部件,标志国机重装成为全球首家具备500兆瓦冲击式水电机组核心铸锻件制造能力的企业。

  国机重装作为国内能源装备领域铸锻件主力供应商,在500兆瓦球阀铸钢件研制过程中,先后突破了超大壁厚球阀铸钢件内部质量保障、超大规格超高精度尺寸控制、高性能碳锰钢组织精准调控等技术瓶颈,成功掌握了500兆瓦级冲击式球阀铸钢件制造全流程关键核心技术。

  据悉,扎拉水电站利用60公里“几”字大拐弯天然落差,截弯取直形成近700米高的水头,具有高水头、大容量、高海拔等特点,是我国实现冲击式水轮发电机组全产业链完全自主知识产权国产化、提升我国高落差水能资源开发能力的支撑示范工程。(完)
