3G三螺桿泵,3GR三螺桿泵
三螺桿泵包括3G通用型,3GC船用型及特殊型。三螺桿泵是轉子式窖泵,由于主動螺桿與從動螺桿上螺旋槽相互嚙合及它們與襯套三孔內表面的配合,得以在三螺桿泵的進出口之間形成數級動密封腔室,這些動密封腔室將不斷把液體由泵進口軸向移動到泵出口,并使所輸送液體逐漸升壓,從而形成一個連續,平穩,軸向移動的壓力液體。
三螺桿泵所輸液體為各種不含固體顆粒,無腐蝕性油類及類似油的潤滑性液體,所輸液體粘度為1.2~100OE(3.0~760cst),含高粘度液體亦可通過加溫降粘后輸送.流量范圍:0.2~590m3/h*高工作壓力100bar,*高溫度150℃
1、三螺桿泵輸送介質為直線連續輸送、無攪拌、無脈動。
2、三螺桿泵振動小,噪音低。
3、三螺桿泵壓力高、效率高。
4、三螺桿泵結構簡單、拆裝方便。
5、三螺桿泵體積小,重量輕。
6、三螺桿泵磨損輕微,壽命長。
一般采用機械密封。三螺桿泵通過爪型聯軸器由電動機驅動。從主軸外伸端向泵年,為順時針旋轉。主、從螺桿16MnCrS5,40Cr,45,38CrMoALA 泵體:HT200,QT450-10,ZCuSn10Pl,ZG270-5003G系列三螺桿泵包括3G、3GR、3Gr、3GN、3GW。
