螺杆泵依靠螺杆相互啮合空间的容积变化来输送液体。当螺杆转动时吸入腔一端的密封线连续地向排出腔一端作轴向移动,使吸入腔的容积增大,压力降低,液体在压差作用下沿吸入管进入吸入腔。随着螺杆的转动,密封腔内的液体连续而均匀地沿轴向移动到排出腔,由于排出腔一端的容积逐渐缩小,即将液体排出。

4. 关于泵的吸入能力可查阅 样本提供的NPSHR值。
5. 配套电机的选配
泵的选型确定后,根据样本数据可查到泵的轴功率N,该轴功率再加上一定的功率储备后,作为选配电机的依据,一般电机功率Nm应不小于泵轴功率N乘以功率储备系数K后所得值,K值可参照下

· 三螺杆泵的流量、压力在相同转速、粘度时近似呈直线关系,压力越高,流量越小。
· 相同粘度、压力下,泵的流量与转速近似成正比。
· 相同转速、粘度下,轴功率与压力近似成正比。
· 同一粘度、压力下,轴功率与转速近似成正比。
· 粘度增大时,流量和轴功率均增加,但由于其中关系较复杂,必要时可向专业人员咨询。
只要选型得当,维护合理,三螺杆泵就可达到令人满意的运行效果。
