淄川機械密封包括壓力控制、溫度控制、流體替換(堵塞)和雜質去除系統。在淄川機械密封系(xi)(xi)(xi)(xi)統(tong)(tong)中,上述(shu)系(xi)(xi)(xi)(xi)統(tong)(tong)并不同時包括在(zai)內(nei)。密(mi)封(feng)(feng)(feng)(feng)系(xi)(xi)(xi)(xi)統(tong)(tong)的選擇主(zhu)(zhu)要(yao)取決于主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)件的應(ying)(ying)用(yong)(yong)范圍。例如(ru)(ru),如(ru)(ru)果(guo)主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)用(yong)(yong)于高溫液體(ti),密(mi)封(feng)(feng)(feng)(feng)系(xi)(xi)(xi)(xi)統(tong)(tong)應(ying)(ying)確(que)(que)(que)保(bao)(bao)(bao)降(jiang)(jiang)低主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)的環(huan)境溫度(du),即(ji)采(cai)用(yong)(yong)溫度(du)控制系(xi)(xi)(xi)(xi)統(tong)(tong)。如(ru)(ru)果(guo)主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)用(yong)(yong)于固體(ti)雜質含量高的工(gong)作介質,密(mi)封(feng)(feng)(feng)(feng)系(xi)(xi)(xi)(xi)統(tong)(tong)應(ying)(ying)確(que)(que)(que)保(bao)(bao)(bao)在(zai)主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)前降(jiang)(jiang)低固體(ti)雜質含量,即(ji)采(cai)用(yong)(yong)除(chu)雜系(xi)(xi)(xi)(xi)統(tong)(tong)。在(zai)腐(fu)蝕(shi)性介質中,密(mi)封(feng)(feng)(feng)(feng)系(xi)(xi)(xi)(xi)統(tong)(tong)必須確(que)(que)(que)保(bao)(bao)(bao)主(zhu)(zhu)密(mi)封(feng)(feng)(feng)(feng)降(jiang)(jiang)低腐(fu)蝕(shi)速(su)率或(huo)消除(chu)腐(fu)蝕(shi),即(ji)使用(yong)(yong)流體(ti)而不是(shi)堵(du)塞流體(ti)系(xi)(xi)(xi)(xi)統(tong)(tong);在(zai)高壓密(mi)封(feng)(feng)(feng)(feng)裝置中,輔助(zhu)系(xi)(xi)(xi)(xi)統(tong)(tong)應(ying)(ying)確(que)(que)(que)保(bao)(bao)(bao)多(duo)級降(jiang)(jiang)壓和其(qi)他措施,即(ji)壓力(li)控制系(xi)(xi)(xi)(xi)統(tong)(tong)。
淄川機械密封的三個主(zhu)要功(gong)能如下:
1、沖洗功能,沖洗是淄川機械密封基本的功能,它直接將液體注入單面密封或雙面密封的高壓側。一般的淄川機械密封應該沖(chong)洗(xi),特別是(shi)對于輕(qing)烴(jing)泵,沖(chong)洗(xi)時(shi)達到隔離介質(zhi)(zhi)、冷卻和改善潤滑的目(mu)的。隔離介質(zhi)(zhi)的目(mu)的可以通過將(jiang)與介質(zhi)(zhi)相容(rong)的液體引入密(mi)封腔(qiang)進(jin)行外(wai)部循(xun)環沖(chong)洗(xi)來(lai)實現(xian)。
2、除雜和過濾功能,密封流體中的微細固體粒子、污垢等雜質對淄川機械密封造成的(de)(de)危害非常嚴重,可能導致密(mi)(mi)封端面的(de)(de)磨損,也(ye)可能堵(du)塞寒冷密(mi)(mi)封系統(tong)的(de)(de)管(guan)線。密(mi)(mi)封性系統(tong)軟件具有去(qu)除殘(can)(can)渣、保持液(ye)體(ti)清潔的(de)(de)作用(yong)。當(dang)殘(can)(can)渣的(de)(de)相(xiang)對密(mi)(mi)度小于液(ye)體(ti)媒質相(xiang)對密(mi)(mi)度時,能用(yong)過(guo)濾(lv)裝置去(qu)除殘(can)(can)渣;而(er)當(dang)殘(can)(can)渣的(de)(de)相(xiang)對密(mi)(mi)度超過(guo)液(ye)體(ti)媒質相(xiang)對密(mi)(mi)度時,可選用(yong)旋液(ye)分離設(she)備(bei)或網(wang)式(shi)過(guo)濾(lv)器去(qu)除殘(can)(can)渣。
3、流體替代功能,含有固體顆粒的氣相介質和液相介質的直接密封難度很大,它們溫、毒、貴、易蒸發、易結晶。借助淄川機械密封可以用雙端淄川機械密封代替密封介(jie)質(zhi),將(jiang)難(nan)以直接(jie)密封的介(jie)質(zhi)轉化為密封潤滑性能(neng)好、清潔的密封液體介(jie)質(zhi)。
