高唐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。在高唐機械密封系(xi)(xi)統(tong)(tong)(tong)(tong)中，上述系(xi)(xi)統(tong)(tong)(tong)(tong)并不(bu)同時(shi)包括在內。密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)(tong)的(de)選擇主要(yao)取(qu)決于主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件的(de)應(ying)(ying)用(yong)(yong)范圍。例(li)如(ru)，如(ru)果主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)用(yong)(yong)于高(gao)溫液體(ti)，密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)(tong)應(ying)(ying)確保降(jiang)低(di)(di)主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)環境溫度，即采(cai)用(yong)(yong)溫度控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)。如(ru)果主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)用(yong)(yong)于固體(ti)雜(za)質含量高(gao)的(de)工作介(jie)質，密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)(tong)應(ying)(ying)確保在主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)前降(jiang)低(di)(di)固體(ti)雜(za)質含量，即采(cai)用(yong)(yong)除雜(za)系(xi)(xi)統(tong)(tong)(tong)(tong)。在腐(fu)蝕(shi)性介(jie)質中，密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)(tong)必須(xu)確保主密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)降(jiang)低(di)(di)腐(fu)蝕(shi)速(su)率或消(xiao)除腐(fu)蝕(shi)，即使用(yong)(yong)流體(ti)而不(bu)是堵塞流體(ti)系(xi)(xi)統(tong)(tong)(tong)(tong)；在高(gao)壓(ya)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)裝置(zhi)中，輔助系(xi)(xi)統(tong)(tong)(tong)(tong)應(ying)(ying)確保多(duo)級降(jiang)壓(ya)和(he)其他(ta)措施，即壓(ya)力(li)控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)。

　　高唐機械密封的三個(ge)主要功能如(ru)下：

　　1、沖洗功能，沖洗是高唐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。一般的高唐機械密封應該沖(chong)(chong)洗，特別(bie)是對于輕(qing)烴泵，沖(chong)(chong)洗時達到隔(ge)離介(jie)質、冷卻和改善潤滑的(de)目的(de)。隔(ge)離介(jie)質的(de)目的(de)可以通(tong)過將與介(jie)質相容的(de)液體(ti)引(yin)入密封腔進行外部循環沖(chong)(chong)洗來實現。

　　2、除雜和過濾功能，密封流體中的微細固體粒子、污垢等雜質對高唐機械密封造成的(de)(de)危害非常嚴(yan)重，可(ke)能導致(zhi)密(mi)(mi)封端面的(de)(de)磨損，也可(ke)能堵塞寒冷密(mi)(mi)封系統(tong)的(de)(de)管線。密(mi)(mi)封性系統(tong)軟(ruan)件具有去除(chu)殘(can)(can)渣(zha)、保(bao)持(chi)液(ye)(ye)體清潔的(de)(de)作用。當殘(can)(can)渣(zha)的(de)(de)相對密(mi)(mi)度小于液(ye)(ye)體媒質(zhi)相對密(mi)(mi)度時，能用過濾裝(zhuang)置(zhi)去除(chu)殘(can)(can)渣(zha)；而(er)當殘(can)(can)渣(zha)的(de)(de)相對密(mi)(mi)度超過液(ye)(ye)體媒質(zhi)相對密(mi)(mi)度時，可(ke)選用旋液(ye)(ye)分離設備或(huo)網式過濾器(qi)去除(chu)殘(can)(can)渣(zha)。

　　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。借助高唐機械密封可以用雙端高唐機械密封代替密(mi)封(feng)介質，將難以直接密(mi)封(feng)的介質轉化為(wei)密(mi)封(feng)潤滑(hua)性能好、清潔(jie)的密(mi)封(feng)液(ye)體(ti)介質。
