三螺桿泵是轉(zhuǎn)子式容積泵，它是利用螺桿嚙合原理，依靠旋轉(zhuǎn)的螺桿在泵套內(nèi)相互嚙合，把被輸送的介質(zhì)封閉在嚙合腔內(nèi)，沿螺桿軸向連續(xù)勻速地推至排出口，為系統(tǒng)提供穩(wěn)定的壓力。
三螺桿泵適用于各種無腐蝕性油類及類似油和潤滑性液體。輸送液體的粘度范圍一般為3.0-760mm2/s(1.2-100oE),高粘度介質(zhì)可通過加溫降粘后輸送。其溫度不超過350℃。
我公司生產(chǎn)的LQ3G保溫螺桿泵（保溫型瀝青泵）主要用于輸送高粘度和高溫潤滑性液體。常用于瀝青重燃油、重齒輪油等介質(zhì)的輸送。熱載體可以是蒸汽、熱油和熱水，冷載體可以是氣體和液體。
特點：
三螺桿泵的顯著特點是結(jié)構(gòu)簡單、壓力脈動小、流量穩(wěn)定、工作平衡可靠、允許高轉(zhuǎn)速、噪音低，效率高、壽命長、有自吸能力。
用途及使用范圍：
三螺桿泵廣泛應用于石油、化纖、冶金、機械、電力、機床、船舶、玻璃、公路等各行各業(yè)。
三螺桿泵適用于輸送燃料油、潤滑油、液壓油、原油、瀝青及其它類似油的潤滑油和潤滑性液體。
三螺桿泵在工業(yè)領(lǐng)域中作潤滑泵，在液壓系統(tǒng)中作液壓泵，在燃油系統(tǒng)中作輸送及增壓泵，在輸油系統(tǒng)中作輸送及加油泵。
流量范圍0.2-600m3/h,*高工作壓力可達6.3MPa。
