摘要國電諫壁發電廠於1999年與英國帕森斯公司合作,對7號汽輪機高低壓缸通流部分進行了改造,取得了較好的效果。Cylinder wall thickness
汽缸壁厚度In this system, cylinder walls are lubricated by splashing oil thrown off from the connecting - rod bearings
在這一系統中,汽缸壁是由連桿軸承運動飛濺起來的油進行潤滑的。The oil is thrown upward as droplets or fine mist and provides adequate lubrication to valve mechamisms, piston pins, cylinder walls, and piston rings
飛濺上來的油形成油滴或油舞,使氣門機構,活塞銷,汽缸壁和活塞環得到充分的潤滑Highly oxidation resistance and shear stable formulation, to release and remove the deposits of piston skirt and cylinder. restrain the oil mud in high or low temperature to keep the engine highest clean
具有優良的清凈分散性,有效減緩及清除汽缸壁及活塞上的沉積物,抑制高低溫油泥的生成,保持發動機高度清潔。On the basis of the above, integrating with the practical facts about the test for width and thickness of stripe in the in - wall of cylinder after laser thermal treatment, it is proved that the feasibility of eddy - current test technology applied in the lest for width and thickness of stripe in the in - wall of cylinder after laser thermal treatment
在此基礎上,結合汽缸內壁激光熱處理條紋厚度和寬度檢測的實際情況,證明了電渦流多頻率多參數檢測技術在汽缸內壁激光熱處理條紋厚度和寬度檢測中的可行性。Starting with automation system, this paper, firstly, outlines the status of sensor lying in automation field and its developing state, shows the superiority about eddy current test by comparing it with the other nondestructive tests, expatiates the modern developing state about eddy current technology both here and there, shows the vista about eddy current test in our country and the background of the subject about the test for the width and thickness of stripe in the in - wall of cylinder after laser thermal treatment. secondly, beginning with maxwell equation in electromagnetic field theory and combining with some electromagnetic phenomena in real life, this paper explains qualitatively the operating principle about eddy current technology and the test theory for multi - parameter test with multi - frequency by math illation and gives some applying occasions about it
通過同其它幾種無損檢測技術的比較,給出了電渦流技術的優越性,闡述了國內外電渦流技術的發展現狀,展望了我國電渦流技術發展的未來,給出了汽缸內壁激光熱處理條紋厚度與寬度的檢測這個課題的背景;然後從電磁場理論中的麥克斯韋方程出發,通過一系列的數學嚴密推導,並結合現實生活中的一些電磁現象,定性地解釋了電渦流技術的原理,以及電渦流傳感器多頻率多參數的檢測原理,給出了電渦流技術的部分應用場合,以及電渦流檢測的等效電路。By raising the temperature of the cylinder walls in this way, the outward flow of heat is greatly reduced
通過這樣來給氣缸壁升溫,蒸汽熱量的向外流失大幅減少。分享友人
