龍江機械密封的這三個功能一定要了解

  龍江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。在龍江機械密封系(xi)統(tong)(tong)(tong)中(zhong)(zhong),上述系(xi)統(tong)(tong)(tong)并不(bu)同(tong)時包括在(zai)內。密(mi)(mi)封(feng)(feng)(feng)系(xi)統(tong)(tong)(tong)的(de)選擇主(zhu)要取決(jue)于主(zhu)密(mi)(mi)封(feng)(feng)(feng)件(jian)的(de)應用(yong)(yong)范圍(wei)。例如(ru),如(ru)果主(zhu)密(mi)(mi)封(feng)(feng)(feng)用(yong)(yong)于高溫(wen)液體(ti)(ti),密(mi)(mi)封(feng)(feng)(feng)系(xi)統(tong)(tong)(tong)應確(que)保降低主(zhu)密(mi)(mi)封(feng)(feng)(feng)的(de)環境溫(wen)度,即(ji)采用(yong)(yong)溫(wen)度控制系(xi)統(tong)(tong)(tong)。如(ru)果主(zhu)密(mi)(mi)封(feng)(feng)(feng)用(yong)(yong)于固(gu)體(ti)(ti)雜質(zhi)(zhi)含量高的(de)工作介質(zhi)(zhi),密(mi)(mi)封(feng)(feng)(feng)系(xi)統(tong)(tong)(tong)應確(que)保在(zai)主(zhu)密(mi)(mi)封(feng)(feng)(feng)前降低固(gu)體(ti)(ti)雜質(zhi)(zhi)含量,即(ji)采用(yong)(yong)除雜系(xi)統(tong)(tong)(tong)。在(zai)腐蝕性介質(zhi)(zhi)中(zhong)(zhong),密(mi)(mi)封(feng)(feng)(feng)系(xi)統(tong)(tong)(tong)必(bi)須確(que)保主(zhu)密(mi)(mi)封(feng)(feng)(feng)降低腐蝕速率或消除腐蝕,即(ji)使用(yong)(yong)流(liu)體(ti)(ti)而不(bu)是堵塞流(liu)體(ti)(ti)系(xi)統(tong)(tong)(tong);在(zai)高壓密(mi)(mi)封(feng)(feng)(feng)裝置中(zhong)(zhong),輔助系(xi)統(tong)(tong)(tong)應確(que)保多級降壓和其他措(cuo)施,即(ji)壓力控制系(xi)統(tong)(tong)(tong)。


  龍江機械密封的三個主要(yao)功能(neng)如下:


  1、沖洗功能,沖洗是龍江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。一般的龍江機械密封應該沖洗(xi)(xi),特別是對于輕(qing)烴(jing)泵(beng),沖洗(xi)(xi)時達到隔離(li)介(jie)質、冷卻和改善(shan)潤滑的目的。隔離(li)介(jie)質的目的可以通過將與(yu)介(jie)質相(xiang)容的液體引入密封腔(qiang)進行外部循(xun)環沖洗(xi)(xi)來實現。

  2、除雜和過濾功能,密封流體中的微細固體粒子、污垢等雜質對龍江機械密封造(zao)成的危害非常嚴重,可能導致密封(feng)端面的磨損,也(ye)可能堵塞寒冷(leng)密封(feng)系(xi)統的管(guan)線。密封(feng)性系(xi)統軟件具有去除殘(can)(can)渣(zha)、保(bao)持(chi)液體清潔的作用。當(dang)殘(can)(can)渣(zha)的相對密度(du)小(xiao)于液體媒(mei)質相對密度(du)時(shi),能用過濾(lv)裝(zhuang)置去除殘(can)(can)渣(zha);而當(dang)殘(can)(can)渣(zha)的相對密度(du)超過液體媒(mei)質相對密度(du)時(shi),可選用旋液分離設備或(huo)網式過濾(lv)器去除殘(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。借助龍江機械密封可以用雙端龍江機械密封代替密封(feng)介質,將難(nan)以直接密封(feng)的介質轉化為密封(feng)潤滑(hua)性能(neng)好、清(qing)潔的密封(feng)液體介質。
