結果表明,泄漏的主要原因是焊接缺陷導致焊縫區發生縫隙腐蝕,而工作介質的局部酸性、流體的流動形態、大氣中有害物質、溫差應力等綜合作用,加上使用期過長等加劇了腐蝕,導致該塔泄漏。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焊接工藝從分段焊和局部加熱兩個方面進行了優化,結果表明:採用普通工藝焊接時,葉片焊后殘余拉應力出現在焊縫及其附近區域,並且在葉片出水邊的熔合線附近(危險區域)出現了峰值;在採用優化的分段焊時,先焊兩端后焊中間的方法可以降低葉片危險區域的焊接殘余拉應力峰值,降低效果與葉片出水邊焊段長度、焊縫各段的焊接方向有關;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、加熱溫度以及加熱面積成正比,與冷卻面積成反比,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。Meixing electronics factory is major in the vacuum tube stereo power amplifier, which is located in the nanhai city , owned a workhouse over 1300 square meter, with five plant, they are box, seal and transformer circling 、 debugging & check, we also have the machine process, such as milling machine 、 punch 、 drill press 、 electric welding 、 matrix 、 incision machine, and radio tube test machine. we have realize the product line manufacture, the monthly whole output is over 200 sets

計算結果表明:塔壁外側在冷卻水面到達的瞬間進入塑性屈服,筒節中部塑性屈服區較大,當靠近焊縫時塔壁的塑性變形區逐漸縮小直至消失,塔壁塑性屈服區的分佈特點解釋了塔體長期使用后發生鼓凸變形及簡體與焊縫連接處產生裂紋的原因。All cracks were detected in regions where such manually made weld passes existed.
