燃气轮机中间缸制造技术的研究

An Examination on the Manufacturing Technology of Gas Turbine Intermediate Cylinder

作为E级燃气轮机的关键部件,中间缸的尺寸庞大,毛坯采用焊接组合件,材料软,是大型壁薄零件[1],加工极易变形。介绍了E级燃气轮机中间缸加工的一种新方法,详细阐述了该加工方法具体的加工流程、加工特点以及所需工装工具。该加工新方法解决了壁薄气缸加工装夹变形问题,解决了立车加工中校中心的难题,从而确保中间缸的加工精度,实现燃气轮机关键部件中间缸制造技术的优化突破。

As a key component of E-class gas turbine, the intermediate cylinder is huge in size, owing to that the blank is made of welded assembly it is a large-scale, thin wall part with soft material that is easily deformed during processing. Introduced a new method to process intermediate cylinder of E-class gas turbine with detailed specific processing procedures, processing characteristics and the required special tools of the processing method. This approach can settle the issues and problems such as deformation of thin-walled cylinder during clamping ＆ processing, centering in vertical lathe, so that the machining accuracy of the intermediate cylinder could be ensured by optimization and breakthrough of the manufacturing technology of key components in gas turbine-the intermediate cylinder.
