SMC油霧分離器的結構:
SMC油霧(wu)分(fen)離器外(wai)殼內(nei)帶(dai)有加(jia)(jia)熱(re)蒸(zheng)汽夾套(tao),其(qi)內(nei)裝(zhuang)有可(ke)(ke)旋轉(zhuan)(zhuan)(zhuan)的(de)(de)葉片即刮(gua)板。刮(gua)板有固定式(shi)和(he)轉(zhuan)(zhuan)(zhuan)子式(shi)兩種(zhong)(zhong)(zhong),前者(zhe)與殼體(ti)內(nei)壁的(de)(de)間隙(xi)為0.5~1.5mm,后者(zhe)與器壁的(de)(de)間隙(xi)隨轉(zhuan)(zhuan)(zhuan)子的(de)(de)轉(zhuan)(zhuan)(zhuan)數而變。料(liao)液(ye)由蒸(zheng)發(fa)器上部沿切線(xian)方向加(jia)(jia)入(亦有加(jia)(jia)至與刮(gua)板同軸的(de)(de)甩料(liao)盤上的(de)(de))。由于重力(li)、離心力(li)和(he)旋轉(zhuan)(zhuan)(zhuan)刮(gua)板刮(gua)帶(dai)作用,溶(rong)液(ye)在(zai)器內(nei)壁形成(cheng)下(xia)旋的(de)(de)薄膜,并在(zai)此過程中被蒸(zheng)發(fa)濃縮,完(wan)成(cheng)液(ye)在(zai)底部排出。這種(zhong)(zhong)(zhong)蒸(zheng)發(fa)器是一(yi)種(zhong)(zhong)(zhong)利(li)用外(wai)加(jia)(jia)動(dong)力(li)成(cheng)膜的(de)(de)單(dan)程型蒸(zheng)發(fa)器,其(qi)突出優點是對物料(liao)的(de)(de)適應(ying)性很強,且停(ting)留時間短,一(yi)般為數秒或幾(ji)十(shi)秒,故可(ke)(ke)適應(ying)于高粘度(如(ru)栲(kao)膠、蜂蜜等)和(he)易結晶、結垢、熱(re)敏(min)性的(de)(de)物料(liao)。但(dan)其(qi)結構(gou)復雜,動(dong)力(li)消耗(hao)大,每平方米傳熱(re)面約需(xu)1.5~3kW。此外(wai),其(qi)處理量很小且制造安裝(zhuang)要求(qiu)高。
SMC油霧分離器維護方法:
1、正常使用(yong)(yong)過程中如發生(sheng)不(bu)(bu)滴油(you)(you)(you)(you)現象時(shi)(shi)(shi),應檢(jian)查(cha)進口空(kong)氣流(liu)量是否(fou)低(di)于(yu)起霧(wu)流(liu)量,是否(fou)漏氣,油(you)(you)(you)(you)量調(diao)節針(zhen)閥或油(you)(you)(you)(you)路是否(fou)堵塞。2、使用(yong)(yong)時(shi)(shi)(shi)應及(ji)時(shi)(shi)(shi)排除油(you)(you)(you)(you)杯(bei)(bei)底部沉積的水分,以保證潤滑滑油(you)(you)(you)(you)的純度。一般可(ke)通過油(you)(you)(you)(you)霧(wu)器(qi)底部的排水旋鈕排水,排水完畢后應迅(xun)速擰緊旋鈕。3、油(you)(you)(you)(you)杯(bei)(bei)內油(you)(you)(you)(you)面低(di)至(zhi)油(you)(you)(you)(you)位(wei)(wei)下限(xian)(xian)位(wei)(wei)置時(shi)(shi)(shi),應及(ji)時(shi)(shi)(shi)加油(you)(you)(you)(you)。油(you)(you)(you)(you)霧(wu)型(xing)油(you)(you)(you)(you)霧(wu)器(qi)可(ke)實現不(bu)(bu)停(ting)(ting)氣加油(you)(you)(you)(you);微霧(wu)型(xing)油(you)(you)(you)(you)霧(wu)器(qi)必須先停(ting)(ting)氣,后加油(you)(you)(you)(you)。油(you)(you)(you)(you)面不(bu)(bu)得超(chao)過油(you)(you)(you)(you)位(wei)(wei)上限(xian)(xian)位(wei)(wei)置。4、油(you)(you)(you)(you)杯(bei)(bei)一般是用(yong)(yong)聚碳酸脂制(zhi)成的透明(ming)容器(qi),應避免(mian)接觸有(you)機溶劑、合成油(you)(you)(you)(you)等,并(bing)避免(mian)在這些化學物(wu)質的氣氛中使用(yong)(yong)。5、定期檢(jian)查(cha)油(you)(you)(you)(you)霧(wu)器(qi)油(you)(you)(you)(you)杯(bei)(bei)的金(jin)屬外(wai)殼是否(fou)完好(hao),油(you)(you)(you)(you)杯(bei)(bei)、視(shi)油(you)(you)(you)(you)窗是否(fou)有(you)裂紋、被污染(ran)。發現密封(feng)圈損壞時(shi)(shi)(shi)應及(ji)時(shi)(shi)(shi)更換。新(xin)的密封(feng)圈應涂上潤滑脂再安裝。
