进入八十年代以来,我国在水电设备的设计制造中,采用新材料、新结构、新工艺、新技术等方面发展很快。近年来,我们在完成水电站的水电设备完善化和水电设备的更新改造方面已取得可喜的成绩,获得了显著的经济效果。例如:下马岭水电站65000千瓦水轮发电机组,增容换用新转轮,在设计工况下,较旧转轮增加出力4500多千瓦;桓仁电站一号机对转轮(HL741—LJ—410)进行了改型,经在48.89米水头下试 Since the 1980s, China has witnessed rapid development in the design and manufacture of hydropower equipment with new materials, new structures, new techniques and new technologies. In recent years, we have made gratifying achievements in completing the hydropower facilities of hydropower stations and in upgrading and rehabilitating hydropower equipment, and achieved remarkable economic results. For example: Xiamaling Hydropower Station 65,000 kilowatts hydro-generating units, capacity change for the new runner, in the design conditions, the older runner to increase output of more than 4500 kilowatts; Huanren Power Station on the 1st runner (HL741-LJ- 410) was modified, after 48.89 meters head under the test
