| 三螺桿泵包括3G通用型，3GC船用型及特殊型。三螺桿泵是轉子式窖泵，由于主動(dòng)螺桿與從動(dòng)螺桿上螺旋槽相互嚙合及它們與襯套三孔內表面的配合，得以在泵的進(jìn)出口之間形成數級動(dòng)密封腔室，這些動(dòng)密封腔室將不斷把液體由泵進(jìn)口軸向移動(dòng)到泵出口，并使所輸送液體逐漸升壓，從而形成一個(gè)連續，平穩，軸向移動(dòng)的壓力液體。 |

| 三螺桿泵所輸液體為各種不含固體顆粒，無(wú)腐蝕性油類(lèi)及類(lèi)似油的潤滑性液體，所輸液體粘度為1.2~100OE(3.0~760cst),含高粘度液體亦可通過(guò)加溫降粘后輸送. |

| 1、介質(zhì)為直線(xiàn)連續輸送、無(wú)攪拌、無(wú)脈動(dòng)。 |
|
|
|
|
|
|
|
|
|
|
|
|
| 2、振動(dòng)小，噪音低。 |
|
|
|
|
|
|
|
|
|
|
|
|
| 3、壓力高、效率高。 |
|
|
|
|
|
|
|
|
|
|
|
|
| 4、結構簡(jiǎn)單、拆裝方便。 |
|
|
|
|
|
|
|
|
|
|
|
|
| 5、體積小，重量輕。 |
|
|
|
|
|
|
|
|
|
|
|
|
| 6、磨損輕微，壽命長(cháng)。 |
