一、工作原理主螺桿隨外界電機做旋轉(zhuǎn)運動（并帶到兩根負螺桿），隨著螺桿螺旋槽周期性打開，吸入腔容積增大，形成真空，真空的壓力差將介質(zhì)被吸入螺旋槽內(nèi)，并被螺旋槽封閉住，隨著螺桿的旋轉(zhuǎn)，介質(zhì)隨螺旋槽沿螺桿軸線向出口移動，zui后介質(zhì)被排除泵外，這就是三螺桿泵的工作原理三螺桿泵部件主要材料材質(zhì)： 泵體:鑄鐵、鑄鋼、碳鋼焊接、不銹鋼 襯套:鑄鐵、球鐵、錫青銅、陶瓷、PTFE、高分子復(fù)合耐磨材料 螺桿:合金鋼、氮化鋼、不銹鋼、錫磷青銅二、應(yīng)用舉例 ：1、石油天然氣煉油廠: 用輸送、循環(huán)、混合或出口泵為所有類型的清潔、潤滑、低粘度和高粘性液體,引擎潤滑油，潤滑油、原油、燃料油。 2、造船 造船學(xué) 造船業(yè): 使用像主機潤滑油泵，柴油機潤滑油、傳輸、控制、液壓、冷卻油、冷卻液、循環(huán)、燃油/柴油泵為柴油機引擎, 燃氣輪機和變速箱。 3、化學(xué)藥品 化學(xué)品 化工: 用轉(zhuǎn)讓、循環(huán)、混合或出口泵為所有類型的清潔、潤滑、低/高粘性液體,引擎添加劑、樹脂、油脂、膠水、粘合劑、多元醇、油漆。 4、發(fā)電和燃油系統(tǒng): 使用作為轉(zhuǎn)移和裝載泵運輸?shù)某林睾洼p油,泵送所有潤滑液體。 5、旋轉(zhuǎn)和通用機械: 用作潤滑油、控制石油、液壓油、冷卻液、循環(huán)油、燃油/柴油泵對柴油發(fā)動機,壓縮機、天然氣、蒸汽、水輪機和變速箱。 6、可輸送介質(zhì)例舉：液壓油、水乙二醇、機械油、齒輪油、燃油、原油、蠟、瀝青、礦物油、透平油、液壓油、煤油、石腦油、潤滑油、樹脂漆、脂肪、棕櫚油、粘膠、瀝青三、HSNH 三螺桿泵特點：（ 1 ）壓力和流量范圍廣泛，流量范圍 0.2 ～ 600m3/h zui高工作壓力可達 4.0MPa ；（ 2 ）運送液體的種類和粘度范圍寬廣；（ 3 ）因為三螺桿泵內(nèi)的回轉(zhuǎn)部件慣性力較低，故可使用很高的轉(zhuǎn)速；（ 4 ）吸入性能好，具有自吸能力；（ 5 ）流量均勻連續(xù)，振動小，噪音低；（ 6 ）與其它回轉(zhuǎn)泵相比，對進入的氣體和污物不太敏感；（ 7 ）三螺桿泵結(jié)構(gòu)堅實，安裝保養(yǎng)容易；（ 8 ）自吸能力強；（ 9 ）由于部件通用組合系列化有多種結(jié)構(gòu)，可用于臥式，法蘭式和立式安裝；（ 10 ）根據(jù)所輸送介質(zhì)需要還可提供加熱或冷卻結(jié)構(gòu)；四、賽姆服務(wù)：1、 解決方案：可為客戶提供專業(yè)的、*的螺桿泵系統(tǒng)應(yīng)用解決方案2、三全： 全天后：無論何時、何地、何種方式
