用途
3G三螺杆泵用来输送温度≤150℃、粘度3-760cSt、不含固体颗粒、无腐蚀性、具有润滑性能的介质
适用压力范围：0.6-2.5Mpa;
适用流量范围:0.6-123m3/h。
主要应用于燃油输送、液压工程、船舶工程，石化及其他工业。
|
|
● 应用范围
1、介质为直线连续输送、无搅拌、无脉动。 2、振动小，噪音低。 3、压力高、效率高。 4、结构简单、拆装方便。可立式安装，节省空间 5、体积小，重量轻。 6、磨损轻微，寿命长。 |
|
● 结构形式
一般采用机械密封。泵通过爪型联轴器由电动机驱动。从轴外伸端向泵看，为顺时针旋转。 |
|
● 材 质
主、从螺杆16MnCrS5,40Cr,45,38CrMoALA 泵体：HT200,QT450-10,ZCuSn10Pl,ZG270-500 |
● 3G型通用螺杆泵按泵的用途分类共分为5个系列
