3G型系列螺桿泵用途
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(yè)。
3G型系列螺桿泵應用范圍
1、介質為直線連續(xù)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。
5、體積小，重量輕。
6、磨損輕微，壽命長。
3G型系列螺桿泵結構形式
一般采用機械密封。泵通過爪型聯(lián)軸器由電動機驅動。從主軸外伸端向泵年，為順時針旋轉。
3G型系列螺桿泵材質
主、從螺桿16MnCrS5,40Cr,45,38CrMoALA
泵體：HT200,QT450-10,ZCuSn10Pl,ZG270-500
3G型系列螺桿泵按泵的用途分類共分為5個系列
