1.1概述 Brjef description
三螺桿泵包括 3G通用型，3GC船用型及特殊型。三螺桿泵是轉子式容積泵，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，并使所輸液體逐級升壓，從而形成一個連續、平穩、軸向移動的壓力液體。
The three spindle screw pumps consist of general design type 3GC and three screw pumps of special design.The three spindle screw pump is a positive displacement rotary pump. Inside the pump casing，as the flanks of teeth of drive screw and idler screws are engaged and the screws are also matched with the three inset holes， several sealed moving chambers are thereby formed in-between the pump inlet and outlet end. These closed chambers will take the medium inside to move from the inlet end axially and let flow pressurized progressively，to have a continuous，constant，axial flow pressured liquid.
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1.2~100°E （3.0~760cst），高粘度液體亦可通過高溫降粘后輸送。
流量范圍0.2~590 m³/h，*高工作壓力100bar，*高溫度150℃。
The three spindle screw pumps are suitable for pumping various kinds of non-corrosive oil without contents of solid grains and liquids similar to lubricating oils，the viscosity of mediums to be conveyed range from 1.2 to 100°E（3.0 to 760 cst），liquid with a higher viscosity could also
be pumped after heating up（lowering down the viscosity）.
The flow range is 0.2~590m³/h, and the maximum working pressure is 100 bar，the highest temperature is 150℃. |
