摘要
西屋型汽轮发电机组在国外早已使用弹性基础 ,但在国内还没有业绩。西屋机型使用弹性基础后有一些问题需要解决 ,因此 ,西屋机型使用弹性基础后 ,可精确地进行动力分析、可不停机进行机组的对中与调整、可解决基础的不均匀沉降、可节省检修时间、可抗地震等。
The spring supported foundations have been used for Westinghouse turbine-generator units all over the world, but no reference is in China up to now. After application of spring supported foundations to Westinghouse units some problems have been solved, including the accurate dynamic analysis, alignment and regulation to the unit without shutdown of unit, uneven settlement of foundation, etc.. This kind of foundation can save the maintenance time and resist to earthquake.
