泵工作時，由于兩從動螺桿與主動螺桿左右對稱嚙合，故作用在主動螺桿上的徑向力完全平衡，主動螺桿不承受彎曲負荷。從動螺桿所受徑向力沿其整個長度都由泵缸襯套來支承，因此，不需要在外端另設(shè) 軸承，基本上也不承受彎曲負荷。在運行中，螺桿外圓表面和泵缸內(nèi)壁之間形成的一層油膜，可防止金屬之間的直接接觸，使螺桿齒面的磨損**減少。 </p> <p> 螺桿泵工作時，兩端分別作用著液體的吸排壓力，因此對螺桿要產(chǎn)生軸向推力。對于壓差小于10千克力/cm2 的小型泵，可以采用止推軸承，惠州螺桿泵生產(chǎn)廠商，惠州螺桿泵生產(chǎn)廠商。此外，還通過主動螺桿的**油孔將高壓油引入各螺桿軸套的底部，從而在螺桿下端產(chǎn)生一個與軸向推力方向相反的平衡推力。 </p> <p> 螺桿泵和其它容積泵一樣，當泵的排出口完全封閉時，泵內(nèi)的壓力就會上升到使泵損壞或使電動機過載的危險程度。所以，在泵的吸排口處，就必須設(shè)置安全閥。 </p> <p> 螺桿泵的軸封，惠州螺桿泵生產(chǎn)廠商，通常采用機械軸封，并可根據(jù)工作壓力的高低采取不同的形式。 </p> <p> <br /> </p><div

1、注意吸入管道密封，***啟動前應在吸入管道室中注滿潤滑性介質(zhì)，并用管子鉗轉(zhuǎn)動數(shù)轉(zhuǎn)。然后啟動。嚴禁在沒有介質(zhì)狀態(tài)下空轉(zhuǎn)，造成定子損壞。 </p> <p> 2、注意電機轉(zhuǎn)向，防止逆轉(zhuǎn)。 </p> <p> 3、使用中隨時注意泵的流量、壓力等狀況，如發(fā)現(xiàn)流量、壓力突然變化或有異聲，應及時檢查解決。 </p> <p> 4、對于高粘度、有結(jié)晶、含顆粒或有腐蝕性介質(zhì)的泵，使用完畢后，應進行清洗，防止沉積或損壞。 </p> <p> 安裝 </p> <p> <br /> </p> <p> <br /> </p> <p> 1、注意污泥螺桿泵的傳動系統(tǒng)的同軸度，出廠前，泵及動力端(有的包括底座)已作調(diào)整。但在安裝時，由于基礎(chǔ)不平，擰緊地腳螺栓，可能造成底座扭曲，造成聯(lián)軸器中心偏移。應重新檢查聯(lián)軸器安裝偏差。 </p> <p> <br /> </p> <p> 2、出液口前應安裝一段長度略大于定子的易拆卸管線，以利于更換定子。 </p> <p> <br /> </p> <p> 3、泵的進口在垂直方向，出口在水平方向，這樣可使密封在負壓狀態(tài)工作，減小密封腔的壓力，旋向：從出口方向看逆時針旋轉(zhuǎn)。另外泵的進出口法蘭(管道)不應承受管道重量，所以管道應設(shè)支撐點。 </p> <p> <br /> </p> <p> 4、管道在安裝前必須清洗干凈，防止異物損壞定子、轉(zhuǎn)子，并造成堵塞。 </p> <p> <br />
