調(diào)速電機(jī)在長期使用過程中，由于周圍的工作環(huán)境條件較差、地面不整潔，時(shí)間一長，由于帶電以及電樞的吸氣作用、電機(jī)電磁的吸引等原因，很容易使塵埃、紙毛、金屬屑等進(jìn)入電機(jī)內(nèi)部，黏附于離合器電樞的內(nèi)孔和磁極轉(zhuǎn)子的表面。一旦積累過多便會(huì)堵塞其間的空隙，使磁極轉(zhuǎn)子與異步電機(jī)同速旋轉(zhuǎn)，出現(xiàn)印刷高速"飛車"、轉(zhuǎn)速無法調(diào)整的現(xiàn)象，嚴(yán)重時(shí)甚至損環(huán)電機(jī)轉(zhuǎn)差離合器控制裝置的有關(guān)元件。因此，對(duì)于膠印機(jī)滑差電機(jī)，應(yīng)每年定期拆下對(duì)其邊行除塵清洗，以避免此類問題的發(fā)生。膠印機(jī)的電氣系統(tǒng)因保養(yǎng)不善常會(huì)出現(xiàn)以下故障。
．主傳動(dòng)電機(jī)運(yùn)轉(zhuǎn)不正常
滑差電機(jī)在運(yùn)轉(zhuǎn)過程中會(huì)劇烈振動(dòng)，引起軸承發(fā)熱。拆開離合器電樞與磁極轉(zhuǎn)子，檢查電機(jī)的軸承是否嚴(yán)重缺乏潤滑油脂，而造成軸承嚴(yán)重磨損，電動(dòng)機(jī)的運(yùn)轉(zhuǎn)性能下降。此時(shí)需要更換已損壞的軸承，并加注好潤滑油脂。正常情況下，應(yīng)對(duì)這部分機(jī)構(gòu)的所有部件進(jìn)行一次清洗、加油，以保證主傳動(dòng)電機(jī)的正常運(yùn)行。

一般固體材料中的聲速隨其溫度升高而降低，有試驗(yàn)數(shù)據(jù)表明，熱態(tài)材料每增加1C，聲速下降1%。對(duì)于高溫在役設(shè)備常常碰到這種情況。應(yīng)選用高溫專用探頭和高溫耦合劑（3－6C)，切勿使用普通探頭。層疊材料、復(fù)合（非均質(zhì)）材料。要測(cè)量未經(jīng)耦合的層疊材料是不可能的，因超聲波無法穿透未經(jīng)耦合的空間，而且不能在復(fù)合（非均質(zhì)）材料中勻速傳播。對(duì)于由多層材料包扎制成的設(shè)備（像尿素高壓設(shè)備），測(cè)厚時(shí)要特別注意，測(cè)厚儀的示值僅表示與探頭接觸的那層材料厚度。
減速器-型號(hào)選擇
盡量選用接近理想減速比：
減速比=伺服馬達(dá)轉(zhuǎn)速/減速機(jī)出力軸轉(zhuǎn)速
扭力計(jì)算：
對(duì)減速機(jī)的壽命而言,扭力計(jì)算非常重要,并且要注意加速度的轉(zhuǎn)矩值(TP),是否超過減速機(jī)之負(fù)載扭力.
適用功率通常為市面上的伺服機(jī)種的適用功率,減速機(jī)的適用性很高,工作系數(shù)都能維持在1.2以上,但在選用上也可以以自己的需要來決定:
要點(diǎn)有二:
A.選用伺服電機(jī)的出力軸徑不能大于表格上使用軸徑.
B.若經(jīng)扭力計(jì)算工作,轉(zhuǎn)速可以滿足平常運(yùn)轉(zhuǎn),但在伺服全額輸出時(shí),有不足現(xiàn)象時(shí),我們可以在電機(jī)側(cè)之驅(qū)動(dòng)器,做限流控制,或在機(jī)械軸上做扭力保護(hù),這是很必要的.

不少人都認(rèn)為電動(dòng)閥貴，使用成本高，據(jù)知，其實(shí)不然，如果以整體計(jì)算，傳統(tǒng)閥要加上許多配件及管路安裝，價(jià)格并未占優(yōu)勢(shì)，反而要承擔(dān)較多的保養(yǎng)費(fèi)用。就電動(dòng)閥而言，因電動(dòng)閥具備裝配容易、故障率低以及符合業(yè)界自動(dòng)化需求的優(yōu)點(diǎn)，是業(yè)者較劃算的選擇。因?yàn)槭褂靡话銈鹘y(tǒng)氣動(dòng)閥，免不了要有配管、電磁閥及壓縮機(jī)等才能匹配，而電動(dòng)閥是以馬達(dá)驅(qū)動(dòng)，安裝簡易省事，且電動(dòng)閥安裝配合工廠原有的自控線路即可，可節(jié)省其他成本支出。此外，以馬達(dá)驅(qū)動(dòng)方式開閉較平順，無瞬間沖力過大的缺點(diǎn)，故障率可大幅降低。
