    <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(jì)量泵的原理知道，對(duì)于外置軸承的丁苯膠乳泵丁苯膠乳計(jì)量泵，通過(guò)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(dòng)由同步齒輪完成。齒輪箱中有獨(dú)立的潤(rùn)滑，與泵工作腔隔開。這種結(jié)構(gòu)的優(yōu)點(diǎn)大大拓寬了丁苯膠乳泵丁苯膠乳計(jì)量泵的使用范圍，即：除了輸送潤(rùn)滑性良好的介質(zhì)外，還可輸送大量的非潤(rùn)滑性介質(zhì)，各種粘度（最高粘度可達(dá)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(jì)量泵由于其恒定間隙的存在以及型線上的特點(diǎn)，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(jì)量泵非常獨(dú)特的優(yōu)點(diǎn)之一。

    <SPAN style="FONT-FAMILY: 宋體; mso-ascii-font-family: " Roman??

    <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(jì)量泵還可干轉(zhuǎn)。由于運(yùn)動(dòng)部件在工作時(shí)互不接觸，因此短時(shí)的干轉(zhuǎn)不會(huì)破壞泵元件，這種特點(diǎn)給自動(dòng)控制的流程提供了極大的方便，但干運(yùn)轉(zhuǎn)時(shí)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(jì)量泵在輸送過(guò)程中無(wú)剪切，無(wú)乳化作用，因此不會(huì)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(dòng)依靠同步齒輪，泵運(yùn)轉(zhuǎn)噪音低，振動(dòng)小，工作平穩(wěn)。
