随着我国水利资源的开发应用，近年来大型水电机组不时涌现，大型水轮机转轮被普遍应用。随着机组容量的增大，其构造尺寸不时增大，受其制造才能和程度的限制，所需大型转轮叶片受制于人，全部需求进口。为此，展开大型转轮叶片关键技术的研讨已成为燃眉之急。

　　哈尔滨电机厂有限义务公司多年来不断承当着为国度制造大型发电机组的任务，所承当的景洪电站水轮机转轮制造任务，叶片原定由罗马尼亚进口，因其外方不能按期交货，哈电决议自行研制，处理受制于人的技术难题。

　　哈电热加工事业部接到任务后，立刻组织精干的技术队伍投入研制工作。这一任务难度很大，景洪叶片呈“L”型，转轮直径为8.3m，为巨型机组；最大轮廓尺寸为4500mm×3300mm，而且易变形。依照请求，叶片加工余量要控制在5～38mm范围内，加工后的叶片公差仅为2mm。针对高难度的研制任务，他们设计了三套工艺计划，找出各个环节的工艺难点，制定了相应的工艺措施。经过多日的努力，胜利研制出5片景洪叶片。经检测，各项指标均满足或超越技术请求。近半年来，经过进一步的开发、研制，目前可完成批量消费，创始了我国批量制造巨型水轮机叶片的先河。

 With the development and utilization of water resources, large hydropower generating units continue to emerge in recent years, large turbine runner has been widely used. With the increasing capacity of the units, the structure size is increasing, and by its manufacturing capacity and level of restrictions, the required large-scale runner blade control of others, all imported. To this end, to carry out large-scale rotor blades on key technologies has become imperative.

Harbin Electric Machinery Co., Ltd. has been manufacturing for the country undertaking the task of large generating units, assumed the task Jinghong Power Station turbine blade manufacture, leaves the original imports from Romania, can not be scheduled because of the foreign delivery, HEC has decided to develop and solve the kinds of technical problems.

Harbin Electric Division, received the task of processing immediately after the organization capable of the technical team put into development work. This task is very difficult, Jinghong leaves were "L" type, wheel diameter is 8.3m, for the giant unit; maximum profile size 4500mm × 3300mm, and easy to shape. As requested, the leaves of allowances to control the range of 5 ~ 38mm, tolerance of processed leaves of only 2mm. Difficult task for the development, they designed a three technology programs that identify all aspects of the process difficult to develop the corresponding technical measures. After several days of efforts, successful production of 5 Jinghong leaves. After testing, the indicators are to meet or exceed the technical requirements. Past six months, after further development, development, production can be achieved at present, creating a giant turbine blades of high-volume manufacturing of the first of its kind.
