在高參數(shù)或超臨界汽輪機(jī)中，高、中壓轉(zhuǎn)子溫度較高，這會(huì)引起轉(zhuǎn)子材料彈性模量的變化。材料的彈性模量隨溫度的升高而降低，從而使轉(zhuǎn)子的彎曲的剛度和臨界轉(zhuǎn)速降低，故在分析計(jì)算中應(yīng)計(jì)入轉(zhuǎn)子溫度變化的影響。當(dāng)汽缸或軸承座溫度較高時(shí)（如空載下汽輪機(jī)葉片的鼓風(fēng)作用），會(huì)引起支撐系統(tǒng)動(dòng)剛度降低，使得軸瓦振動(dòng)增大。另外，當(dāng)負(fù)荷運(yùn)行后，如果轉(zhuǎn)子存在不均勻的溫度分布，會(huì)導(dǎo)致轉(zhuǎn)子產(chǎn)生熱彎曲，引起振動(dòng)增大。在高參數(shù)、大容量，尤其是超臨界汽輪機(jī)的高壓轉(zhuǎn)子中，由于汽隙（葉頂間隙和汽封間隙）的不均勻會(huì)引起附加的蒸汽力作用，他可能影響軸系的穩(wěn)定性，使失穩(wěn)轉(zhuǎn)速降低。另外，對于噴嘴調(diào)節(jié)的汽輪機(jī)，在某些負(fù)荷工況，因部分進(jìn)汽改變軸承的動(dòng)特性，也可能導(dǎo)致軸承失穩(wěn)。 <p> <br /> </p> </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">旋轉(zhuǎn)機(jī)械，尤其是大型汽輪發(fā)電機(jī)組軸系的振動(dòng)十分復(fù)雜，影響因素較多，不但有靜態(tài)的，而且有動(dòng)態(tài)的，并且這些因素往往綜合作用，相互影響。當(dāng)轉(zhuǎn)子的工作轉(zhuǎn)速接近其臨界轉(zhuǎn)速時(shí)，就要發(fā)生共振，這是產(chǎn)生極大振動(dòng)的主要原因之一。因此，在轉(zhuǎn)子設(shè)計(jì)時(shí)，應(yīng)保證工作轉(zhuǎn)速相對于其臨界轉(zhuǎn)速有足夠的避開率。通常軸承座的振動(dòng)幅值與轉(zhuǎn)子激振力的大小成正比，與支承系統(tǒng)的動(dòng)剛度成反比。所以，在轉(zhuǎn)子激振力一定的條件下，軸承座的振動(dòng)大小主要決定于支承系統(tǒng)的動(dòng)剛度。增大軸承座的剛度，可使振動(dòng)響應(yīng)峰值轉(zhuǎn)速略有抬高，但可較大的降低軸承座振動(dòng)峰值。為避免轉(zhuǎn)子與支座發(fā)生共振現(xiàn)象，應(yīng)使支座自振頻率與工作頻率之比大于2。.調(diào)查法?；仡櫣收习l(fā)生前打火、冒、異味、供電變化、雷擊、潮濕、誤操作、誤維修。</p><div

style="text-indent:25px">工程振動(dòng)量值的物理參數(shù)常用位移、速度和加速度來表示。由于在通常的頻率范圍內(nèi)振動(dòng)位移幅值量很小，且位移、速度和加速度之間都可互相轉(zhuǎn)換，所以在實(shí)際使用中振動(dòng)量的大小一般用加速度的值來度量。常用單位為：米/秒2?(m/s2?)，或重力加速度(g)。??描述振動(dòng)信號(hào)的另一重要參數(shù)是信號(hào)的頻率。絕大多數(shù)的工程振動(dòng)信號(hào)均可分解成一系列特定頻率和幅值的正弦信號(hào)，因此，對某一振動(dòng)信號(hào)的測量，實(shí)際上是對組成該振動(dòng)信號(hào)的正弦頻率分量的測量。對振動(dòng)變送器主要性能指標(biāo)的考核也是根據(jù)傳感器在其規(guī)定的頻率范圍內(nèi)測量幅值精度的高低來評定。???.直觀法。觀察回路外部損傷、導(dǎo)壓管泄漏，回路過熱，供電開關(guān)狀態(tài)等。江蘇高精度TS-V-3振動(dòng)變送器</p><p
