style="text-indent:25px">升液管的使用壽命與設(shè)備本身的結(jié)構(gòu)特點和使用中的各種條件及升液管徑尺寸有關(guān)。機臺鋼性好震動較小,爐體移位較少且平穩(wěn)、繁、管體受熱溫差不大、管徑較粗壁厚均勻且不易堵鋁的，使用壽命較長。因受氮化硅升液管材料自身持性的影響,特提出一些應(yīng)多加注意的原則: 1、盡量減輕機械碰撞,特別是在搬運及安裝調(diào)試時, 猛烈的撞擊和不均勻的受力,將**縮短升液管的使用壽命。 2、盡量減輕機械震動,特別是在熱狀態(tài)下,持續(xù)的受力和震動,將**縮短升液管的使用壽命。 3、盡量減輕溫差波動，特別是在急促升溫及降溫時,反復(fù)的熱沖擊將**縮短升液管的使用壽命。另外，機臺使用人員的操作水平、經(jīng)驗、熟練程度也非常大的影響升液管的使用壽命。要想延長升液管的使用壽命,必須在各個環(huán)節(jié) 注意,嚴(yán)格把關(guān)持之以恒。 </p></p><br /><p>文章來源地址:
