用途
3G三螺桿泵用來輸送溫度≤150℃、粘度3-760cSt、不含固體顆粒、無腐蝕性、具有潤滑性能的介質
適用壓力范圍：0.6-2.5Mpa;
適用流量范圍:0.6-123m3/h。
主要應用于燃油輸送、液壓工程、船舶工程，石化及其他工業。
|
|
● 應用范圍
1、介質為直線連續輸送、無攪拌、無脈動。 2、振動小，噪音低。 3、壓力高、效率高。 4、結構簡單、拆裝方便。可立式安裝，節省空間 5、體積小，重量輕。 6、磨損輕微，壽命長。 |
|
● 結構形式
一般采用機械密封。泵通過爪型聯軸器由電動機驅動。從軸外伸端向泵看，為順時針旋轉。 |
|
● 材 質
主、從螺桿16MnCrS5,40Cr,45,38CrMoALA 泵體：HT200,QT450-10,ZCuSn10Pl,ZG270-500 |
● 3G型通用螺桿泵按泵的用途分類共分為5個系列
