單雙螺桿泵和普通的工作原理及產(chǎn)品介紹，螺桿泵是利用螺桿的回轉(zhuǎn)來吸排液體的。螺桿為主動螺桿，由原動機(jī)帶動回轉(zhuǎn)，兩邊的螺桿為從動螺桿，隨主動螺桿作反向旋轉(zhuǎn)。主、從動螺桿的螺紋均為雙頭螺紋。由于各螺桿的相互嚙合以及螺桿與襯筒內(nèi)壁的緊密配合，在泵的吸入口和排出口之間，就會被分隔成一個或多個密封空間。隨著螺桿的轉(zhuǎn)動和嚙合，這些密封空間在泵的吸入端不斷形成，將吸入室中的液體封入其中，并自吸入室沿螺桿軸向連續(xù)地推移至排出端，將封閉在各空間中的液體不斷排出，猶如一螺母在螺紋回轉(zhuǎn)時被不斷向前推進(jìn)的情形那樣，這就是螺桿泵的基本工作原理。 </p> <p> <br /> </p> <p> 螺桿泵有單螺桿泵、雙螺桿泵和三螺桿泵。 </p> <p> <br /> </p> <p> 螺桿泵的工作原理是：螺桿泵工作時，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間，當(dāng)主動螺桿旋轉(zhuǎn)時，螺桿泵密封容積在螺牙的擠壓下提高螺桿泵壓力，并沿軸向移動。由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。 </p> <p> <br /> </p> <p> 螺桿泵特點(diǎn)為：螺桿泵損失小，經(jīng)濟(jì)性能好。壓力高而均勻，流量均勻，轉(zhuǎn)速高，能與原動機(jī)直聯(lián)。 </p> <p> <br /> </p> <p> 螺桿泵可以輸送潤滑油，輸送燃油，輸送各種油類及高分子聚合物，用于輸送黏稠液體。 </p> <p> <br /> 質(zhì)量螺桿泵高性價比選擇使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="質(zhì)量螺桿泵高性價比選擇,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876899248047/2424011.jpg"></div><p> 下面以三螺桿為例。 </p> <p> 它主要是由固定在泵體中的襯套（泵缸）以及安插在泵缸中的主動螺桿和與其嚙合的兩根從動螺桿所組成。三根互相嚙合的螺桿，在泵缸內(nèi)按每個導(dǎo)程形成為一個密封腔，造成吸排口之間的密封。 </p> <p> 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(fù)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(fù)荷。在運(yùn)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。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(dāng)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(jī)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，通常采用機(jī)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><p> G型單螺桿泵螺桿軸磨損原因分析，G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個理想塑化的加工溫度范圍，應(yīng)該控制料筒加工溫度，使之接近這個溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會到達(dá)加料段，在加料段必然會出現(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時，很易造成料筒內(nèi)壁及螺桿表面磨損增大。同樣，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會造成磨損增快。2、轉(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強(qiáng)化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對金屬材質(zhì)的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時，如果用高的轉(zhuǎn)速成，則在提高對塑料的剪切力的同時，亦將令強(qiáng)化相應(yīng)地產(chǎn)生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機(jī)礦物質(zhì)在金屬表面高速滑行時，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。
