術文件，如需修改或變更，應由設計單位、設備制造廠出具相應

的證明文件，辦理相關的審批手續。發電廠土建工程除滿足本規

范《電力建設施工技術規范第1部分：土建工程》的規定外，

特殊要求按本部分相關規定執行。

1.0.4汽輪發電機組的施工應按設備訂貨合同、技術協議及制造

廠有效技術文件的要求執行，如合同協議及制造廠技術文件無明

確要求或要求不全面時，按本部分規定執行。

DL5190.3—XXXX

2術語

2.0.1橢圓度ellipticity

最大直徑與最小直徑之差。

2.0.2不柱度non-cylindricity

圓柱形軸或孔通過軸中心線的軸向剖面上下線與平行線的偏

差。其數值為該軸或孔在軸向剖面上最大與最小直徑之差。要求

為正圓柱體的部件，不柱度表示偏離正圓柱要求的程度。

2.0.3錐度taper

圓錐、圓臺形狀回轉面與基準面的傾斜程度。對于圓錐形狀

其數值為圓錐基準面直徑與圓錐高度的比值，對于圓臺形狀其數

值為上下直徑之差與圓臺高度的比值。

2.0.4傾斜度tilt/（坡度）tilt（gradient）

直線或平面與基準線或基準面相交的傾斜程度。其數值為給

定的基準面或線長度內該面或線與基準面或線的最小距離與給定

長度的比值。

2.0.5平面度flatness

實際表面偏離標準平面的程度。其數值用實際平面距離標準

平面最遠點的距離值表示。

2.0.6不平行度non-parallelism

兩個相互平行的線或面間的不平行的程度。其數值為該二要

素間最大與最小垂直距離之差。

2.0.7不垂直度non-perpendicularity

兩條軸線、軸線與平面或兩平面之間所形成的角度與標準直

角之差。以單位長度內標準垂直線或面與所測線或面的最小距離

△表示，單位△/m。

2.0.8徑向晃度radialrunout

2

DL5190.3—XXXX

徑向晃度表示測量斷面所在的軸表面到軸中心線距離的偏離

程度。用百分表垂直指向被測斷面的軸中心線，轉子軸頸在支持

面上盤動，被測表面上各點讀數的最大與最小值之差，為軸頸在

該截面的徑向晃度。

2.0.9端面瓢偏endingrunout

端面瓢偏表示該端面與軸中心線不垂直的程度。在被測端面

接近直徑的周邊部位，相對180°位置各安放一個垂直于端面的百

分表，盤動轉子，兩表同時指示的最大差值減去最小差值的1/2

即為端面瓢偏值。

2.0.10大型水泵largepumps

徑大于700mm的低壓泵。

2.0.11高速水泵high-speedpumps

額定轉速高于1500r/min的水泵。

2.0.12可調式汽封adjustablesteamseal

可調式汽封是一種隨著啟動過程中蒸汽壓力的逐漸增大而分

段閉合的汽封。其主要特點：啟動時，汽封塊張開，使動靜部分

達到最大間隙，避免了啟動過程中由于振動及變形而導致的碰磨。

隨著機組升速加負荷，汽封塊端部閉合，使動靜間隙減小，以減

少汽封的漏汽量從而提高機組的效率。

2.0.13空冷凝汽器air-cooledcondenser（ACC）

空冷凝汽器簡稱為ACC，指以空氣作為冷卻介質，使汽輪機

排汽凝結成水的表面式換熱器。

2.0.14相對振動relativevibration

相對振動是指轉軸和相應結構（例如軸承座或機殼）之間的

徑向位移量的測量值，如無特別說明，本部分中的“軸振動”均

指相對振動。

2.0.15絕對振動absolutevibration

絕對振動是指轉軸相對于某一慣性參考系的位移量的測量值。

3

DL5190.3—XXXX

2.0.16輔機故障減負荷試驗runbacktest

當發生部分主要輔機故障停運，機組最大出力低于給定負荷

時，測試控制系統將機組負荷快速降低到實際所能達到的出力，

并控制機組在允許參數范圍內繼續運行能力的過程，稱為輔機故

障減負荷試驗。
