caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px;"> 由双螺杆泵的原理知道，对于外置轴承的双螺杆泵，通过轴承定位，两根螺杆在衬套中互不接触，齿侧之间保持恒定的间隙（其间隙值由工况及泵本身规格决定），螺杆外圆与衬套内圆面也保持恒定的间隙不变。两根螺杆的传动由同步齿轮完成。齿轮箱中有独立的润滑，与泵工作腔隔开。这种结构的优点大大拓宽了双螺杆泵的使用范围，即：除了输送润滑性良好的介质外，还可输送大量的非润滑性介质，各种粘度（高粘度可达 3*106mm/s ）的介质以及具有腐蚀性（酸、碱等性质），磨蚀性的液体、�/span><br style="white-space: normal;

font-family: 宋体; font-size: 14px;"> 双螺杆泵由于其恒定间隙的存在以及型线上的特点，其属于非密封型容积泵，因此除了输送纯液体外，还可输送气体和液体的混合物，即汽液混输，这也是双螺杆泵非常独特的优点之一� 双螺杆泵由于结构的独特设计，可以自吸而无须专门的自吸装置，而且由于轴向输送轴流速度较小而具备很强的吸上能力即很小的 NPSHr 值、�/span><br style="white-space: normal;

font-family: 宋体; font-size: 14px;"> 双螺杆泵还可干转。由于运动部件在工作时互不接触，因此短时的干转不会破坏泵元件，这种特点给自动控制的流程提供了极大的方便，但干运转时间受多种因素限制，一般很短、�/span><br style="white-space: normal; -webkit-text-size-adjust: auto; caret-color: rgb(51, 51, 51);
