3QGB螺[Luo]杆瀝[Li]青泵(又名保溫泵|保溫瀝青泵),是一種容積式泵,在三螺杆泵中,由于主螺杆與從動(Dong)螺[Luo]杆上螺旋槽相[Xiang]互齧合及它們與襯套三孔内表面的配合,得[De]以在泵的與出口之間形[Xing]成數(Shu)級動密封室(Shi),這些動密封室将[Jiang]不斷把[Ba]液體由泵(Beng)軸向移動到泵出口,并(Bing)使所[Suo]輸送液[Ye]體逐級[Ji]升壓。從而[Er]形成一個連(Lian)續、平穩(Wen)、軸向移動的壓力液體。顯著的優點是結構簡單、體積小、允許[Xu]高轉速、工作平穩、壓(Ya)力脈動小[Xiao]、流量穩定、噪音(Yin)低、,是高粘度保溫泵。用于瀝青庫、油田、重油等[Deng]油庫(Ku)和導熱油[You]蒸氣加熱,瀝青(Qing),重油等設備配套。
二、用途及使[Shi]用範圍[Wei]
3QGB三螺杆[Gan]泵所輸送液體為不含固體顆粒,無(Wu)腐蝕性油(You)類及類[Lei]似油的潤滑性(Xing)液體,粘度為1.2~100oE(3.0~760cst),高粘[Zhan]度液體亦可通過加(Jia)溫降粘後輸送,其溫度不超過150oC。LQ3G三螺杆泵(Beng)廣泛應用(Yong)于石油、化纖(Xian)、冶金、機械、電力、機床、船舶、玻璃、公路等(Deng)各行各業。3QGB三螺杆泵[Beng]适用(Yong)于輸送燃料油[You]、潤滑油、液壓油、原[Yuan]油、瀝青及其它類似油的潤滑油和潤滑性液體。LQ3g三螺(Luo)杆泵在工業中作潤滑泵,在液[Ye]壓系(Xi)統中作液壓泵[Beng],在[Zai]燃油系統中作輸(Shu)送及(Ji)增壓泵,在輸油[You]系統中作輸[Shu]送[Song]及加油泵。
流量範[Fan]圍0.2-600m3/h,工作壓力可達6.3MPa
三、結構與性能特點
1、結構簡單:泵本身[Shen]僅三根螺杆(Gan)組(Zu)成,但有多種結構[Gou]形成,一般小流(Liu)量(Liang),0.2-6.5m3/h泵(Beng)的泵體和襯套合為一個[Ge]卧式安裝(Zhuang),軸封為機械密封。中等流量以上(Shang)的(De)泵襯套為一單[Dan]獨的零件固定[Ding]于泵體内。大流量泵[Beng]多(Duo)制成雙吸結構。軸根據輸送的介質不(Bu)同有端面機械密封和填料密(Mi)封兩種[Zhong]。船用泵(Beng)的原動機為交(Jiao)流船用電機。
2、壽命長:三螺杆泵(Beng)的主要螺[Luo]杆是由電動機驅動[Dong]。主、從螺杆之間,螺杆與襯套之間皆有一層油膜保護,因泵的機械摩擦。
3、所輸(Shu)的液(Ye)體在泵内作(Zuo)軸向勻速直線運動,故壓力(Li)脈動小,流量穩(Wen)定,噪音低,由于[Yu]轉動[Dong]部分慣性[Xing]小,則起動力矩[Ju]和振動很小。
4、具有高(Gao)吸入能[Neng]力[Li]。
5、為泵、電機[Ji]及管(Guan)路系[Xi]統,中等流量[Liang]以上的螺杆(Gan)泵均[Jun]帶有閥,當壓力超過閥設(She)定壓力時,高壓(Ya)油将回流至泵的。圖1圖2帶閥和(He)不帶閥的兩種結構原理圖。
