为提高质量和寿命,涡轮盘和压缩机盘在制造中要进行预应力处理,而为避免微观裂纹的存在,还要进行低温超速试验。本文介绍了德国申克公司向美国GE公司提供的超速试验台及试验过程。
In order to improve the quality and life expectancy, the turbine disc and the compressor disc are to be prestressed during the manufacturing process. In order to avoid the existence of microcracks, the low temperature over speed test is also to be carried out. This article describes the speeding test rigs and test procedures provided by Germany Schenck to GE in the United States.
