3QGB三螺杆泵[Beng](又名(Ming)保溫泵|保[Bao]溫瀝(Li)青泵),是一[Yi]種容積式[Shi]泵,在三螺杆泵中,由(You)于主螺杆與從(Cong)動螺杆上螺旋槽相互齧合及它們與(Yu)襯套三孔内(Nei)表面的配[Pei]合,得以在泵的與出口之間形成數級動(Dong)密封(Feng)室,這些動密封室(Shi)将不斷把液體(Ti)由泵軸向移動到泵出口,并(Bing)使所輸送液體(Ti)逐級升壓。從而形成一個(Ge)連續(Xu)、平穩、軸向移動[Dong]的壓力液體。顯(Xian)著的(De)優點(Dian)是結構簡單(Dan)、體積小[Xiao]、允許高轉(Zhuan)速、工作平穩、壓力脈動小[Xiao]、流量穩(Wen)定、噪音低、,是(Shi)高粘度[Du]保溫泵。用于(Yu)瀝青庫、油田、重油等油庫和導熱油蒸氣加熱,瀝青,重油等設(She)備配套。
二、用途(Tu)及使用範圍
3QGB三螺(Luo)杆泵所[Suo]輸送液體為不含固(Gu)體顆粒,無(Wu)腐蝕性油[You]類及(Ji)類似油的潤滑性(Xing)液體,粘度為1.2~100oE(3.0~760cst),高粘[Zhan]度液體亦可通過加溫降粘後輸送,其溫度不超過150oC。LQ3G三螺杆泵廣泛應用[Yong]于石[Shi]油、化纖、冶金、機械、電力、機床、船舶、玻璃、公路等各行各業。3QGB三螺杆泵适用于輸送燃料油[You]、潤滑油、液壓油、原油、瀝青及其它類[Lei]似油的潤滑油[You]和(He)潤滑性(Xing)液體。3QGB三螺杆泵在[Zai]工(Gong)業中作潤滑泵,在液壓(Ya)系統中作液(Ye)壓泵,在燃油系統中作輸[Shu]送及增壓泵,在輸油系統中作輸送及加油泵。
流量範圍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:泵本身僅三根螺杆組成[Cheng],但有多種結構形成,一般(Ban)小流量,0.2-6.5m3/h泵(Beng)的泵體和襯(Chen)套合為[Wei]一個卧[Wo]式安裝,軸封為機械[Xie]密封。中等流[Liu]量以[Yi]上的泵襯套為一單獨的(De)零件(Jian)固定(Ding)于泵體内。大流量泵多制成雙吸結[Jie]構。軸根據輸送的介質不[Bu]同有端面機械密封和填[Tian]料密封兩種。船(Chuan)用泵的原動機[Ji]為交流船用電[Dian]機。
2、壽命長(Zhang):三螺杆泵的主要(Yao)螺杆是由電動機驅[Qu]動。主、從螺杆之間,螺杆[Gan]與襯套之間皆有一(Yi)層油膜保護,因[Yin]泵的[De]機械摩擦。
3、所[Suo]輸的液體在泵内作軸向(Xiang)勻[Yun]速直線運動,故[Gu]壓力脈動小,流量穩定,噪(Zao)音低,由(You)于轉動部分[Fen]慣性小,則起動力矩(Ju)和振動很小。
4、具有高吸入[Ru]能力。
5、為泵、電機[Ji]及管路系統,中[Zhong]等流量以上的螺杆泵均帶有閥,當壓力超過[Guo]閥設定壓力時[Shi],高壓(Ya)油将回流[Liu]至泵的。圖1圖2帶閥[Fa]和不帶[Dai]閥的兩種結構原理圖。
