<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯胶乳输送泵在运行时时,旋转轮及衬套之间会形成密封腔,随着旋转轮每转动一周,便会由进口向出口移出一个密封腔,也就是一个密封腔的体积的液体被排出去。而在理想状态下,双丁苯胶乳输送泵内部无泄漏的话,泵的流量与转速就会成正比。即:Qth=n*q

<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>由丁苯胶乳泵丁苯胶乳计量泵的原理知道,对于外置轴承的丁苯胶乳泵丁苯胶乳计量泵,通过轴承定位,两根旋转轮在衬套中互不接触,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),旋转轮外圆与衬套内圆面也保持恒定的间隙不变。两根旋转轮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丁苯胶乳泵丁苯胶乳计量泵的使用范围,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(最高粘度可达3*106mm/s<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>)的介质以及具有腐蚀性(酸、碱等性质),磨蚀性的液体。
<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯胶乳泵丁苯胶乳计量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,这也是丁苯胶乳泵丁苯胶乳计量泵非常独特的优点之一。
<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯胶乳泵丁苯胶乳计量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<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>值。
<SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯胶乳泵丁苯胶乳计量泵还可干转。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 style="FONT-FAMILY: 宋体; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>另外丁苯胶乳泵丁苯胶乳计量泵在输送过程中无剪切,无乳化作用,因此不会破坏分子链结构和工况流程中所形成的特定的流体性质,并且由于传动依靠同步齿轮,泵运转噪音低,振动小,工作平稳。
