1.1概述 Brjef description
三螺杆泵包括 3G通用型，3GC船用型及特殊型。三螺杆泵是转子式容积泵，由于主动螺杆与从动螺杆上螺旋槽相互啮合及它们与衬套三孔内表面的配合，得以在泵的进出口之间形成数级动密封腔室，这些动密封腔室将不断把液体由泵进口轴向移动到泵出口，并使所输液体逐级升压，从而形成一个连续、平稳、轴向移动的压力液体。
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.
三螺杆泵所输液体为各种不含固体颗粒，无腐蚀性油类及类似油的润滑性液体，所输液体粘度为1.2~100°E （3.0~760cst），高粘度液体亦可通过高温降粘后输送。
流量范围0.2~590 m³/h，*高工作压力100bar，*高温度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℃. |
