320px;" alt="揭陽(yáng)螺桿泵廠家直供,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906640625/2770674.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(dòng)螺桿和與其嚙合的兩根從動(dòng)螺桿所組成。三根互相嚙合的螺桿，在泵缸內(nèi)按每個(gè)導(dǎo)程形成為一個(gè)密封腔，造成吸排口之間的密封。 </p> <p> 泵工作時(shí)，由于兩從動(dòng)螺桿與主動(dòng)螺桿左右對(duì)稱(chēng)嚙合，故作用在主動(dòng)螺桿上的徑向力完全平衡，主動(dòng)螺桿不承受彎曲負(fù)荷。從動(dòng)螺桿所受徑向力沿其整個(gè)長(zhǎng)度都由泵缸襯套來(lái)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(shí)，兩端分別作用著液體的吸排壓力，因此對(duì)螺桿要產(chǎn)生軸向推力。對(duì)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(guò)主動(dòng)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(gè)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(shí)，泵內(nèi)的壓力就會(huì)上升到使泵損壞或使電動(dòng)機(jī)過(guò)載的危險(xiǎn)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> 雙螺桿泵由同步齒輪驅(qū)動(dòng)，連接兩組螺旋線。螺桿之間沒(méi)有接觸，無(wú)機(jī)械摩擦，使用壽命長(zhǎng)。單螺桿泵是一種橡膠套定子和轉(zhuǎn)子的嚙齒動(dòng)物和嚙齒動(dòng)物，利用輸送介質(zhì)潤(rùn)滑，摩擦導(dǎo)致橡膠套容易損壞，一般壽命在半年內(nèi)，輸送純潤(rùn)滑介質(zhì)更合適，如果雜質(zhì)會(huì)**降低使用壽命。但其缺點(diǎn)也很明顯：加工精度較高，加工難度增大。特別是，加工精度的不足會(huì)影響轉(zhuǎn)子和定子的均勻性，并使上述優(yōu)點(diǎn)不再存在；加工時(shí)間和生產(chǎn)成本高，這是生產(chǎn)較少的原因。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 當(dāng)然，它也可以制造出一個(gè)具有更多的轉(zhuǎn)子和定子螺旋頭的單螺桿泵，例如三個(gè)螺旋轉(zhuǎn)子和兩個(gè)內(nèi)部螺旋定子泵，但是對(duì)制造精度的要求更高，并且流量不總是隨著螺旋數(shù)的增加而增加。磁頭，因此沒(méi)有實(shí)際意義。雖然這種轉(zhuǎn)子和定子對(duì)的螺旋頭數(shù)不適用于單螺桿泵，但它已廣泛應(yīng)用于石油機(jī)械螺桿鉆具領(lǐng)域。

單螺桿泵的嚙合副型線，近十多年來(lái)國(guó)外有些廠商開(kāi)發(fā)雙頭螺旋的轉(zhuǎn)子和三頭內(nèi)嚙合螺旋的定子相嚙合的單螺桿泵進(jìn)展很快，個(gè)別的廠商已發(fā)展到大批量生產(chǎn)和銷(xiāo)售。我國(guó)也有少數(shù)制造廠進(jìn)行研制，目前尚處在開(kāi)發(fā)階段。 </p> <p> 雙頭螺旋轉(zhuǎn)子和三頭內(nèi)螺旋定子構(gòu)成的單螺桿泵與單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子構(gòu)成的單螺桿泵相比較，有著如下的優(yōu)點(diǎn)： </p> <p> 1）在相同轉(zhuǎn)速和相同橫向尺寸的螺旋段情況下，有著較大的流量，或在相同激量時(shí)導(dǎo)程T的尺寸較小。 </p> <p> 2）由于轉(zhuǎn)子每轉(zhuǎn)一周，密封腔數(shù)為2×3 =6,而單頭螺旋轉(zhuǎn)子和雙頭內(nèi)螺旋定子的泵，密封腔數(shù)為1×2 =2,因此其流量脈動(dòng)和壓力脈動(dòng)較小。 </p> <p> 3 ）轉(zhuǎn)子的偏心距較小，因此噪聲和振動(dòng)也隨之降低，并允許采用較高的轉(zhuǎn) 速，或在相同的轉(zhuǎn)速和相同流量時(shí)，吸上性能更好。 </p> <p> 4）容積效率和機(jī)械效率也更高。 </p> <p> 5)起動(dòng)力距較小。 </p> <p> 6)壽命更長(zhǎng)。 </p> <p> <br />

不同金屬在電解質(zhì)溶液中的電位不同，它們之間會(huì)產(chǎn)生電位差；同一金屬由于本身**不均勻在電解質(zhì)溶液中也有可能產(chǎn)生電位差；同一金屬在電解質(zhì)溶液中所處的環(huán)境條件有差別（如濃度、溫度和應(yīng)力差別等）也會(huì)產(chǎn)生電位差。而在酸、堿、鹽等電解質(zhì) </p> <p> <br /> </p> <p> 溶液中都存在著帶正電荷的陽(yáng)離子和帶負(fù)電荷的陰離子，電位差成了電解質(zhì)溶液中離子移動(dòng)的推動(dòng)力，離子移動(dòng)到電極上得失電子的同時(shí)便會(huì)產(chǎn)生金屬的腐蝕，并同時(shí)產(chǎn)生電流。因此，電化學(xué)腐蝕是由于金屬發(fā)生腐蝕電池作用引起的。如果將兩種電位不同的金屬（如銅和鋅）用導(dǎo)線連接起來(lái)，放在電解質(zhì)溶液（如?。?SO4溶液）中,這樣就構(gòu)成了導(dǎo)電回路，回路中的電子將從低電位的鋅流向高電位的銅，電子的移動(dòng)產(chǎn)生電流，形成腐蝕電池。鋅不斷失去電子，變?yōu)殇\離子進(jìn)人溶液，鋅電極成為腐蝕電池的極，出現(xiàn)腐蝕；銅電極成為腐蝕電池的陰極而被保護(hù)，溶液中的H＋不斷移動(dòng)到銅電極上得到電子而析出H2。
