影響雙(shuang)級(ji)真(zhen)空濾油機的因素很多：

重慶中(zhong)凈過濾設備(bei)專(zhuan)用(yong)生產制(zhi)造雙級真(zhen)(zhen)空濾油(you)機(ji)在恒(heng)壓作(zuo)用(yong)下(xia)，介(jie)質傳(chuan)(chuan)導(dao)(dao)(dao)電(dian)(dian)(dian)流的(de)(de)能力(li)(li)稱(cheng)為(wei)電(dian)(dian)(dian)導(dao)(dao)(dao)率(lv)(lv)，電(dian)(dian)(dian)導(dao)(dao)(dao)率(lv)(lv)的(de)(de)倒數稱(cheng)為(wei)介(jie)質電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)。換(huan)句話說，全自動真(zhen)(zhen)空濾油(you)機(ji)的(de)(de)導(dao)(dao)(dao)電(dian)(dian)(dian)性(xing)是油(you)在給定壓力(li)(li)下(xia)在兩(liang)個(ge)電(dian)(dian)(dian)極(ji)之(zhi)(zhi)間傳(chuan)(chuan)導(dao)(dao)(dao)電(dian)(dian)(dian)流的(de)(de)能力(li)(li)。電(dian)(dian)(dian)導(dao)(dao)(dao)率(lv)(lv)越大，傳(chuan)(chuan)導(dao)(dao)(dao)電(dian)(dian)(dian)流的(de)(de)能力(li)(li)就越大。絕緣油(you)的(de)(de)體(ti)(ti)積電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)是絕緣油(you)在兩(liang)個(ge)電(dian)(dian)(dian)極(ji)之(zhi)(zhi)間單(dan)位體(ti)(ti)積的(de)(de)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)，通常用(yong)p表示(shi)。一般測量兩(liang)極(ji)之(zhi)(zhi)間的(de)(de)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)R，然后(hou)根據下(xia)式計算電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)。對于(yu)低(di)(di)電(dian)(dian)(dian)導(dao)(dao)(dao)率(lv)(lv)、高電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)的(de)(de)石油(you)，其絕緣性(xing)能良(liang)好。普通新型(xing)絕緣油(you)的(de)(de)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)為(wei)1x1012”~ 1x1014q.cm。隨著溫(wen)度的(de)(de)升高，油(you)的(de)(de)粘度降低(di)(di)，油(you)中(zhong)一些導(dao)(dao)(dao)電(dian)(dian)(dian)顆粒的(de)(de)運動速度加快，會降低(di)(di)電(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)率(lv)(lv)。

雙(shuang)級真空濾油機

(1)溫(wen)(wen)度(du)的影(ying)響(xiang)。一般(ban)情況下，濾油器的體積電(dian)阻(zu)率(lv)隨溫(wen)(wen)度(du)的變化(hua)而變化(hua)。因(yin)此，在(zai)測量(liang)過程中，溫(wen)(wen)度(du)必須保持在(zai)規定的值，以免影(ying)響(xiang)測量(liang)結果。

(2)它與電(dian)場強度有(you)關，就像石油(you)測(ce)試一樣(yang)，由于電(dian)場強度不同，測(ce)得的體積電(dian)阻(zu)率也不同。因此，為了使(shi)測(ce)量(liang)結(jie)果具有(you)可比性，應在規定的電(dian)場強度下進行殘差測(ce)定。

(3)與施(shi)加電(dian)壓(ya)的(de)時(shi)間(jian)(jian)有(you)關，即如(ru)果施(shi)加電(dian)壓(ya)的(de)時(shi)間(jian)(jian)不同，剩余的(de)結果也(ye)會(hui)不同。一般在(zai)室溫(wen)下(xia)測(ce)量(liang)時(shi)，施(shi)放(fang)電(dian)壓(ya)的(de)時(shi)間(jian)(jian)應(ying)較長(如(ru)不小于5min)。而在(zai)高溫(wen)下(xia)測(ce)量(liang)時(shi)，可(ke)以縮(suo)短(duan)壓(ya)力時(shi)間(jian)(jian)(如(ru)1min)。

兩級真空濾油(you)機是一種(zhong)過濾變(bian)壓器(qi)(qi)油(you)中固體雜質和水分，提(ti)高變(bian)壓器(qi)(qi)油(you)性能(neng)，提(ti)高變(bian)壓器(qi)(qi)油(you)絕(jue)緣強度的(de)機械設備(bei)。

雙級真空濾油機(ji)工作原(yuan)理

濾(lv)油機工作時，油在復雜(za)的(de)內外(wai)壓差的(de)作用(yong)下(xia)進(jin)入預濾(lv)器，大(da)顆(ke)粒雜(za)質，過濾(lv)器，油多級遠(yuan)紅外(wai)加熱后，進(jin)入特殊個(ge)性化真空(kong)分(fen)(fen)(fen)離(li)器，首先形成霧在真空(kong)分(fen)(fen)(fen)離(li)器，形成薄膜，真空(kong)的(de)接觸面(mian)積擴大(da)數百次(ci)，油中(zhong)的(de)水(shui)分(fen)(fen)(fen)高熱、高真空(kong)，大(da)的(de)表面(mian)，在真空(kong)系(xi)統(tong)快速蒸發和排出的(de)條件下(xia)，泵(beng)送速度高。

真(zhen)空(kong)分離器上(shang)部排(pai)出(chu)的(de)蒸汽先由冷凝器進行冷卻和(he)(he)除濕，再(zai)在冷卻器中(zhong)(zhong)冷卻。冷凝水(shui)被排(pai)到(dao)儲(chu)水(shui)裝置中(zhong)(zhong)，經(jing)過兩(liang)次冷凝和(he)(he)除濕后，終由真(zhen)空(kong)泵排(pai)到(dao)空(kong)氣中(zhong)(zhong)。

真空汽化脫水后，真空分(fen)離器內(nei)的干油(you)通過(guo)油(you)泵(beng)由負壓變為正(zheng)壓。過(guo)濾后，將凈(jing)油(you)從出(chu)油(you)口排出(chu)，完(wan)成凈(jing)油(you)的整個過(guo)程。

雙級(ji)真空濾油(you)機步驟

1、啟動濾油器前(qian)，設(she)置真(zhen)空度和控(kong)制溫度。電接點真(zhen)空計真(zhen)空度設(she)置在(zai)-0.07 ~ 0.092mpa之(zhi)間，溫控(kong)器溫度一般設(she)置在(zai)50 ~ 65℃。

2、打開真空(kong)泵進口管上的閥門，啟動真空(kong)泵，觀(guan)察真空(kong)度(du)的升高(gao)。

3、當(dang)真空度達到設(she)定(ding)真空度時，應(ying)接(jie)(jie)通電接(jie)(jie)點(dian);當(dang)紅外(wai)液位(wei)控(kong)(kong)(kong)制(zhi)(zhi)器(qi)(qi)(qi)(qi)控(kong)(kong)(kong)制(zhi)(zhi)的油(you)(you)泵自動(dong)(dong)開(kai)(kai)(kai)啟時，可(ke)自動(dong)(dong)開(kai)(kai)(kai)啟進口電磁閥。當(dang)進、出(chu)口油(you)(you)達到平衡時，加熱(re)器(qi)(qi)(qi)(qi)可(ke)以(yi)打開(kai)(kai)(kai)。手(shou)動(dong)(dong)打開(kai)(kai)(kai)溫(wen)控(kong)(kong)(kong)器(qi)(qi)(qi)(qi)，自動(dong)(dong)控(kong)(kong)(kong)制(zhi)(zhi)加熱(re)器(qi)(qi)(qi)(qi)是否受熱(re)。(注：加熱(re)器(qi)(qi)(qi)(qi)的使(shi)用由溫(wen)控(kong)(kong)(kong)器(qi)(qi)(qi)(qi)的設(she)定(ding)值和進油(you)(you)電磁閥的雙向(xiang)控(kong)(kong)(kong)制(zhi)(zhi)控(kong)(kong)(kong)制(zhi)(zhi)。換(huan)句(ju)話說(shuo)，只有(you)同時滿足這兩(liang)種條件，加熱(re)器(qi)(qi)(qi)(qi)才會投入(ru)使(shi)用。換(huan)句(ju)話說(shuo)，不允(yun)許在沒有(you)油(you)(you)的情況(kuang)下干燒加熱(re)器(qi)(qi)(qi)(qi)。

4、當石(shi)油(you)(you)進入真空罐和(he)油(you)(you)位達到(dao)上限(xian)紅(hong)外油(you)(you)位的(de)高度，紅(hong)外自(zi)(zi)動(dong)(dong)控(kong)制器給石(shi)油(you)(you)進口(kou)(kou)的(de)電磁(ci)閥(fa)信號關(guan)閉石(shi)油(you)(you)進口(kou)(kou)，同時，油(you)(you)泵自(zi)(zi)動(dong)(dong)打開，和(he)石(shi)油(you)(you)出(chu)口(kou)(kou)開始(shi)釋(shi)放油(you)(you)，防止攝取過多的(de)石(shi)油(you)(you)和(he)石(shi)油(you)(you)。如(ru)果油(you)(you)位低(di)于油(you)(you)位儀(yi)上紅(hong)外油(you)(you)位自(zi)(zi)動(dong)(dong)控(kong)制儀(yi)的(de)下限(xian)高度，油(you)(you)泵將自(zi)(zi)動(dong)(dong)停(ting)止出(chu)油(you)(you)。因此，整個濾油(you)(you)過程(cheng)都是自(zi)(zi)動(dong)(dong)控(kong)制的(de)，無需(xu)觀(guan)看。
