2.应用范围:特点: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。
3.结构形式: 一般采用机器密封。泵通过爪型联轴器由电动机驱动。从主轴外伸端向泵看,为顺时转。
材 质: 主、从螺杆16MnCrS5,40Cr,45,38CrMoAl;泵体:HT200,QT450-10,ZcuSn10Pl,ZG270-500

三螺杆泵性能曲线图:
各型螺杆泵的性能参数,是在介质粘度为75cst时确定的。性能参数表中给出的参数值适用于介质粘度为5-760cst范围内,超出这个范围则根据用户提出的性能参数要求另行确定。
各型螺杆泵性能参数中给出的排除压力是最大工作压力值,在此范围均能正常工作,其工作范围见图。
三螺杆泵性能参数表:从主轴外伸端向泵看,为顺时针旋转。
