运用系统分析方法寻求提高大型水电机组推力轴承运行可靠性的各种技术途径,而加强水轮机轴向水推力的试验研究,采用顶盖排水等技术措施可以大幅度降低水轮机轴向水推力,有效的提高推力轴承运行可靠性。
The system analysis method is used to seek various technical ways to improve the reliability of the thrust bearing of a large hydropower unit. The experimental research on the axial water thrust of the turbine is strengthened. The technical measures such as roof drainage can greatly reduce the axial water thrust of the turbine. Improve thrust bearing operating reliability.
