<SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯膠乳輸送泵在運行時時，旋轉(zhuǎn)輪及襯套之間會形成密封腔，隨著旋轉(zhuǎn)輪每轉(zhuǎn)動一周，便會由進口向出口移出一個密封腔，也就是一個密封腔的體積的液體被排出去。而在理想狀態(tài)下，雙丁苯膠乳輸送泵內(nèi)部無泄漏的話，泵的流量與轉(zhuǎn)速就會成正比。即：Qth=n*q

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>由丁苯膠乳泵丁苯膠乳計量泵的原理知道，對于外置軸承的丁苯膠乳泵丁苯膠乳計量泵，通過軸承定位，兩根旋轉(zhuǎn)輪在襯套中互不接觸，齒側(cè)之間保持恒定的間隙（其間隙值由工況及泵本身規(guī)格決定），旋轉(zhuǎn)輪外圓與襯套內(nèi)圓面也保持恒定的間隙不變。兩根旋轉(zhuǎn)輪的傳動由同步齒輪完成。齒輪箱中有獨立的潤滑，與泵工作腔隔開。這種結(jié)構(gòu)的優(yōu)點大大拓寬了丁苯膠乳泵丁苯膠乳計量泵的使用范圍，即：除了輸送潤滑性良好的介質(zhì)外，還可輸送大量的非潤滑性介質(zhì)，各種粘度（最高粘度可達3*106mm/s<SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>）的介質(zhì)以及具有腐蝕性（酸、堿等性質(zhì)），磨蝕性的液體。

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯膠乳泵丁苯膠乳計量泵由于其恒定間隙的存在以及型線上的特點，其屬于非密封型容積泵，因此除了輸送純液體外，還可輸送氣體和液體的混合物，即汽液混輸，這也是丁苯膠乳泵丁苯膠乳計量泵非常獨特的優(yōu)點之一。

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯膠乳泵丁苯膠乳計量泵由于結(jié)構(gòu)的獨特設計，可以自吸而無須專門的自吸裝置，而且由于軸向輸送軸流速度較小而具備很強的吸上能力即很小的NPSHr<SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>值。

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>丁苯膠乳泵丁苯膠乳計量泵還可干轉(zhuǎn)。由于運動部件在工作時互不接觸，因此短時的干轉(zhuǎn)不會破壞泵元件，這種特點給自動控制的流程提供了極大的方便，但干運轉(zhuǎn)時間受多種因素限制，一般很短。

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman?? New ?Times mso-hansi-font-family: Roman?; Times>另外丁苯膠乳泵丁苯膠乳計量泵在輸送過程中無剪切，無乳化作用，因此不會破壞分子鏈結(jié)構(gòu)和工況流程中所形成的特定的流體性質(zhì)，并且由于傳動依靠同步齒輪，泵運轉(zhuǎn)噪音低，振動小，工作平穩(wěn)。
