  1. The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased

    本文利用數值模擬手段對轉輪的接工藝從分段和局部加熱兩個方進行了優化,結果表明:採用普通工藝接時,葉片后殘余拉應力出現在及其附近區域,並且在葉片出水邊的熔合線附近(危險區域)出現了峰值;在採用優化的分段時,先兩端后中間的方法可以降低葉片危險區域的接殘余拉應力峰值,降低效果與葉片出水邊段長度、各段的接方向有關;局部加熱法降低轉輪危險區域殘余應力的效果主要與加熱時間、加熱溫度以及加熱積成比,與冷卻積成反比,並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。

  4. The paper expounds how to find out the potential safe problems and unobvious defects, such as beyond - limit deflection in fixed girders for gantry bucket wheel stacker / reclaimer, by means of completely checking fixed girders, movable beams, geometric shapes of stiff and flexible supporters, metal thickness and welding and how to solve the safe problems and remove the defects

    摘要通過對門式斗輪堆取料機固定梁、活動梁、剛性支腿、撓性支腿的幾何形狀、金屬厚度、狀況、聯接螺栓狀況進行全檢測,發現門式斗輪堆取料機固定梁存在下撓超標的安全隱患和其他非明顯缺陷,從而對堆取料機的安全狀況有了全的掌握,並根據檢測結論對固定梁下撓缺陷及時進行校消缺,避免發生設備垮塌事故,保證了堆取料機的安全穩定運行。
