螺杆泵的工作原理,形象地做个比喻,可以把螺杆和所输送的介质看做是螺钉和螺母的相对运动。当螺钉转动时,若限制螺钉不能作轴向
移动,则螺母就会沿着螺钉作轴向移动。这里所说的螺钉可以看做是螺杆泵内作旋转运动的螺杆,而充满螺旋槽的介质就是一个液体螺母。但是仅仅按上述原理制作成的机构,由于从泵的排出腔到进口腔相连通,尚不能将输送的介质从泵的吸入腔提升至排出腔,还必须解决泵内螺杆螺旋面在螺杆衬套的孔内啮合形成的螺旋槽空间能有效地将泵的排出腔和吸入腔隔开,螺杆螺旋面之间相互啮合的接触线就起着隔开的作用。这一密封腔实际上起着类似往复式泵中阀的作用。这样才能使螺杆旋转时,液体螺母-密封腔内的介质,能随着密封腔沿着轴向作从吸入腔到排出腔的直线运动,有效地将介质排除泵外。

实际上密封腔是不可能完全密封的,总会有一些介质从排出腔泄露回吸入腔。显然,只有当泄露的那部分介质相当少时,泵的做功才有意义。泄露的介质越少,泵的容积效率就越高,因此,容积效率是衡量螺杆泵性能好坏的一个极为重要的指标。
