The axial thrust is an important indicator for design and safety consideration in hydroelectric power stations using Kaplan turbines. During transients in hydropower stations, the axial thrust is influenced by many factors including water hammer and rotation speed and is difficult to describe preciously. The bifurcation principle is used in the present work to analyze the spiral case as a piping system with branches that each divert part of the flow as it goes around the periphery of the runner. This analytical...

The axial thrust is an important indicator for design and safety consideration in hydroelectric power stations using Kaplan turbines. During transients in hydropower stations, the axial thrust is influenced by many factors including water hammer and rotation speed and is difficult to describe preciously. The bifurcation principle is used in the present work to analyze the spiral case as a piping system with branches that each divert part of the flow as it goes around the periphery of the runner. This analytical approach improves the computational precision. Screw propeller theory is then used to calculate the axial thrust and to analyze factors that influence the thrust. The calculated results agree well with those obtained experimentally.

>=The causes of failure of pivot-copper bushing pairs in a 125MWKaplan turbine (model ZZ500-LH-1020) were analyzed dur-ing overhauling in Gezhouba Hydropower Plant. The type of wearin these rubbing pairs was determined from observations of theirmacroscopic wear appearances and analyzing their wear particlesin the used lubricating-oil for their shape with the ferrgraphy. Itwas indicated that adhesive wear, abrasive wear and fatigue wearexisted in the rubbing pairs. Moreover, alternating stresses resul-ting in static loads with accompanying subsidiary pulsating loadstogether were being produced and transmitted through at the sametime during sliding friction. Such a kind of damage in the rubbingpairs belongs among mechano-sliding fatigue, namely, wear-fa-tigue damage caused by the kinetic interaction of mechanical fa-tigue and sliding friction phenomena. Its problem is categorizedin study of tribo-fatigue which is a "science concerned with wear-fatigue damage and failure of active systems of machines and e-quipments".

对检修中的葛洲坝水力发电厂18号和15号125MW的Kaplan水轮机(ZZ500-LH-1020型)的枢轴-铜瓦摩擦副进行了失效分析。从宏观磨损形貌推断,枢轴-铜瓦摩擦副中存在着粘着磨损、磨料磨损和疲劳磨损三种磨损类型;从对收集到的枢轴-铜瓦摩擦副的润滑油样进行的磨屑铁谱分析中,也证实枢轴-铜瓦摩擦副中存在着粘着磨损、磨料磨损和疲劳磨损;在滑动摩擦过程中,同时还产生着和传递着静载荷拌有脉动的附加载荷的交变负荷,它的损伤属于机械-滑动疲劳损伤。针对枢轴-铜瓦摩擦副的失效原因,探讨了枢轴-铜瓦摩擦副的再制造方案。
