供应三螺杆泵

三螺杆泵包括3G通用型，3GC船用型及特殊型。三螺杆泵是转子式窖泵，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，得以在三螺杆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，并使所输送液体逐渐升压，从而形成一个连续，平稳，轴向移动的压力液体。

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1.2~100OE(3.0~760cst),含高粘度液体亦可通过加温降粘后输送.

流量范围:0.2~590m3/h工作压力100bar,温度150℃

　　1、三螺杆泵输送介质为直线连续输送、无搅拌、无脉动。　　2、三螺杆泵振动小，噪音低。　　3、三螺杆泵压力高、效率高。　　4、三螺杆泵结构简单、拆装方便。　　5、三螺杆泵体积小，重量轻。　　6、三螺杆泵磨损轻微，寿命长。

　　一般采用机械密封。三螺杆泵通过爪型联轴器由电动机驱动。从主轴外伸端向泵年，为顺时针旋转。
