它的最基本形式就是兩個尺寸相同的齒輪在一個緊密配合的殼體內(nèi)相互嚙合旋轉(zhuǎn)，這個殼體的內(nèi)部類似“8”字形，兩個齒輪裝在里面，齒輪的外徑及兩側(cè)與殼體緊密配合。來自于擠出機(jī)的物料在吸入口進(jìn)入兩個齒輪中間，并充滿這一空間，隨著齒的旋轉(zhuǎn)沿殼體運動，最后在兩齒嚙合時排出。 QT泵幾乎可以完全免除壓力波，故可作為系統(tǒng)精確控速的理想機(jī) 械工具使用壓力范圍廣泛 日本Sumitomo住友 QT單聯(lián)內(nèi)嚙合齒輪泵 【抗磨液壓油粘度40cst(ISOVG32油，油溫50℃)，轉(zhuǎn)速1500r/min,進(jìn)口壓力0MPa】 Sumitomo QT32-12.5 Sumitomo QT32-16 Sumitomo QT42-20 Sumitomo QT42-25 Sumitomo QT42-31.5 Sumitomo QT52-40 Sumitomo QT52-50 Sumitomo QT52-63 Sumitomo QT62-80 Sumitomo QT62-100 Sumitomo QT62-125 Sumitomo QT31-20 Sumitomo QT31-25 Sumitomo QT31-31.5 Sumitomo QT41-40 Sumitomo QT41-50 Sumitomo QT41-63 Sumitomo QT51-80 Sumitomo QT51-100 Sumitomo QT51-125 Sumitomo QT61-160 Sumitomo QT61-200 Sumitomo QT61-250 Sumitomo QT33-12.5 Sumitomo QT33-16 Sumitomo QT43-20 Sumitomo QT43-25 Sumitomo QT43-31.5 Sumitomo QT53-40 Sumitomo QT53-50 Sumitomo QT53-63 Sumitomo QT63-80 Sumitomo QT63-100 Sumitomo QT63-125
