多轴系汽轮发电机组中心调整过程分析

多转子的轴系中心调整是一项复杂的工作。实际检修过程中,要经过多次计算,多次试验,并进行优化才能调整到位。针对此情况,引进了由实缸到半缸再到实缸的调整方案,以图表形式编制了汽轮发电机组轴系调整的快速计算方法。并以N335-16.18/538/538汽轮发电机组的轴系大修中心调整过程为例,探讨有关轴系中心计算调整标准的制定,调整计算方法及调整过程中应注意的事项。最后介绍了D600A型汽轮机联轴器螺栓紧固的工艺流程及矢量图法,以期为同类机组的检修调整提供参考。

Analysis on Shaft Centering of Multi-Rotor Turbo-Generator

The shaft centering of multi-rotor units is complicated and tedious. Repeated calculation and testing are needed in maintenance to reach the optimized result. For this situation, a complete-partial-complete cylinder adjustment scheme is proposed, and a chart-based fast calculation method is provided for turbine-generator shaft adjustment. In this paper, the N335-16.18/538/538 type turbine-generator shaft centering is taken as an example to show the standard establishment, calculation approach as well as the key issues which need to pay more attention in practice. Finally, the technological process and vector diagram method for fastening the coupling bolts of D600A type turbines are presented to provide reference for similar units.
