3G小流量三螺杆泵结构特点:
一般采用机械密封(特殊要求,可选用磁力驱动,零泄露结构).泵通过爪型联轴器由电动机驱动.从主轴外伸端向泵看,为顺时针旋转.
3G小流量三螺杆泵优点:
(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;
(5)体积小重量轻;
(6)磨损轻微,寿命长.
3G小流量三螺杆泵用途:
用来输送温度≤150℃,粘度5-760cSt,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.
3G小流量三螺杆泵选泵注意事项
1,介质的润滑性,清洁度,腐蚀性.
2,介质的粘度,温度.
3,介质进,出口压力,安装高度.
4,使用场合的防爆要求.
5,订货时请注明规格,型号,设计使用压力,转速,介质粘度,温度,电机防爆级别,介质名称.
