48、lt;/p><p>　　閥門電動裝置的正確選擇應(yīng)依據(jù)： 1．操作力矩：操作力矩是選擇閥門電動裝置的最主要的參數(shù)。電動裝置的輸出力矩應(yīng)為閥門操作最大力矩的1.2～1.5倍。 2．操作推力：閥門電動裝置的主機(jī)結(jié)構(gòu)有兩種，一種是不配置推力盤的，此時直接輸出力矩；另一種是配置有推力盤的，此時輸出力矩通過推力盤中的閥桿螺母轉(zhuǎn)換為輸出推力。 3．輸出軸轉(zhuǎn)動圈數(shù)：閥門電動裝置輸出軸轉(zhuǎn)動圈數(shù)的多少與閥門的公稱通徑、閥桿螺距、螺紋頭數(shù)

49、有關(guān)，按M=H/ZS計算（式中：M為電動裝置應(yīng)滿足的總轉(zhuǎn)動圈數(shù)；H為閥門的開啟高度，mm；S為閥桿傳動螺紋的螺距，mm；Z為閥桿螺紋頭數(shù)。） 4．閥桿直徑：對于多回轉(zhuǎn)類的明桿閥門來說，如果電動裝置允許通過的最大閥桿直徑不能通過所配閥門的閥桿，便不能組裝成電動閥門。因此，電動裝置空心輸出軸的內(nèi)徑必須大于明桿閥門的閥桿外徑。對于部分回轉(zhuǎn)閥門以及多回轉(zhuǎn)閥門中的暗桿閥門，雖不用考慮閥桿直徑的通過問題，但在選配時亦應(yīng)充分考慮閥桿直徑與鍵槽的尺寸，

51、電機(jī)的容許溫升值。 4．因某種原因轉(zhuǎn)矩限制機(jī)構(gòu)電路發(fā)生故障，使轉(zhuǎn)矩過大。 5．使用環(huán)境溫度過高，相對地使電機(jī)的熱容量下降。 以上是出現(xiàn)超負(fù)荷的一些原因，對于這些原因產(chǎn)生的電機(jī)過熱現(xiàn)象應(yīng)預(yù)先考慮到，并采取措施，防止過熱。 過去對電機(jī)進(jìn)行保護(hù)的辦法是使用熔斷器、過流繼電器、熱繼電器、恒溫器等，但這些辦法也都各有利弊，對于電動裝置這種變負(fù)荷的設(shè)備，絕對可靠的保護(hù)辦法是沒有的。因此必須采取各種方法組合的方式。但由于每臺電動裝置的負(fù)荷情況不同，難

52、以提出一個統(tǒng)一的辦法。但概括多數(shù)情況，也可以從中找到共同點(diǎn)。</p><p>　　采取的過負(fù)荷保護(hù)方式，歸納為兩種： 1．對電機(jī)輸入電流的增減進(jìn)行判斷； 2．對電機(jī)本身發(fā)熱進(jìn)行判斷。 上述兩種方式，無論那種都要考慮電機(jī)熱容量給定的時間余量。如果用單一方式使之與電機(jī)的熱容量特性一致是困難的。所以應(yīng)選擇根據(jù)過負(fù)荷的原因能可靠的動作的方法——組合復(fù)合方式，以實現(xiàn)全面的過負(fù)荷保護(hù)作用。 羅托克電動裝置的電機(jī)，因其在繞組中

53、埋入了與電機(jī)絕緣等級一致的恒溫器，當(dāng)?shù)竭_(dá)額定溫度時，電機(jī)控制回路便會切斷。恒溫器本身熱容量是較小的，而且其限時特性是由電機(jī)的熱容量特性決定的，因此這是一個可靠的方法。 過負(fù)荷的基本保護(hù)方法是： 1．對電機(jī)連續(xù)運(yùn)轉(zhuǎn)或點(diǎn)動操作的過負(fù)荷保護(hù)采用恒溫器； 2．對電機(jī)堵轉(zhuǎn)的保護(hù)采用熱繼電器 3．對短路事故采用熔斷器或過流繼電器。 閥門電動裝置的正確選擇和超負(fù)荷的防止是戚戚相關(guān)的，應(yīng)引起重視。</p><p>　　在扭矩方面
