随着水电站装机容量与单机容量的不断增大,水轮发电机组的稳定性问题,越来越引起人们的重视,要求水电机组的设计、制造、研究等部门努力提高水机组的稳定性能,以保证水电站的安全运行。 从我们水电部门来说,也要在水电站设计施上,运行检修中,采取积极措施,努力改善水电机组的稳定性。其中重要的一条,是要改善过去老式的安装检修办法,提高安装检修水平;在运行中要严密监视水电机组稳定性的各项参数(振动、摆度、压力脉动值等),靠过去那种凭经验,或仅仅依靠百分表、压力表目测是不行的,必须采用先进的测试技术。
With the continuous increase of hydropower station installed capacity and stand-alone capacity, the stability of hydro-generator units has drawn more and more attention and demanded that the design, manufacture and research departments of hydropower units work hard to improve the stability of hydro-units. Ensure the safe operation of hydropower station. From our hydropower department, we must also take active measures to improve the stability of hydropower units during the design, operation and maintenance of hydropower stations. One of the important items is to improve the old-fashioned installation and maintenance methods and improve the level of installation and maintenance. During the operation, the parameters (vibration, swing, pressure pulsation value, etc.) of the stability of hydropower units should be closely monitored. With experience, or just rely on the dial indicator, pressure gauges visual does not work, you must use advanced testing techniques.
