class="title">詳細(xì)說明</p><div id="shumtl2" class="box"><p><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，潮州螺桿泵制造商，可以采用止推軸承。此外，還通過主動(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)，潮州螺桿泵制造商，泵內(nèi)的壓力就會(huì)上升到使泵損壞或使電動(dòng)機(jī)過載的危險(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，潮州螺桿泵制造商，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 />

單螺桿泵是一種單螺桿式輸運(yùn)泵，它的主要工作部件是偏心螺旋體的螺桿（稱轉(zhuǎn)子）和內(nèi)表面呈雙線螺旋面的螺桿襯套（稱定子）。單螺桿泵工作原理是當(dāng)電動(dòng)機(jī)帶動(dòng)泵軸轉(zhuǎn)動(dòng)時(shí)，螺桿一方面則繞本身的軸線旋轉(zhuǎn)，另一方面它又沿襯套內(nèi)表面滾動(dòng)，這樣便會(huì)形成泵的密封腔室。螺桿每轉(zhuǎn)一周，密封腔內(nèi)的液體向前推進(jìn)一個(gè)螺距，隨著螺桿的連續(xù)轉(zhuǎn)動(dòng)，液體螺旋形方式從一個(gè)密封腔壓向另一個(gè)密封腔，***擠出泵體。單螺桿泵常適用于石蠟、糖蜜、果肉、巧克力漿、油漆、柏油、淀粉糊、潤(rùn)滑脂、泥漿、黏土、陶土等介質(zhì)的傳送。雙螺桿泵是外嚙合的螺桿泵，它利用相互嚙合，互不接觸的兩根螺桿來抽送液體。雙螺桿泵的一端伸出泵外的主動(dòng)螺桿由原動(dòng)機(jī)驅(qū)動(dòng)，主動(dòng)螺桿與從動(dòng)螺桿具有不同旋向的螺紋，螺桿與泵體緊密貼合，從動(dòng)螺桿是通過同步齒輪由主動(dòng)螺桿帶動(dòng)的。泵內(nèi)吸入室應(yīng)與排出室嚴(yán)密地隔開，因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應(yīng)盡可能小些，同時(shí)螺桿與泵體、螺桿與螺桿間又相互形成密封腔，保證密閉，否則就可能有液體從間隙中倒流回去。 </p> <p> 雙螺桿泵常適用于潤(rùn)滑油、潤(rùn)滑脂、原油、柏油、燃料油及其他高黏度油等介質(zhì)的傳送。 </p> <p> <br /> </p> <p> <br /> </p><p> 反應(yīng)的種類 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 腐蝕是材料與環(huán)境發(fā)生反應(yīng)的結(jié)果。金屬材料與環(huán)境通常發(fā)生化學(xué)反應(yīng)或電化學(xué)反應(yīng)，非金屬材料與環(huán)境則會(huì)發(fā)生溶脹、溶解、老化等反應(yīng)。 (二）腐蝕的類型及機(jī)理 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 1.按腐蝕的機(jī)理分為化學(xué)腐蝕和電化學(xué)腐蝕兩大類 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 化學(xué)腐蝕是指金屬與干燥的氣體或非電解質(zhì)溶液產(chǎn)生化學(xué)作用而引起的腐蝕?；瘜W(xué)腐蝕通常為干腐蝕，腐蝕速度相對(duì)較小。如碳鋼在鑄造、鍛造、熱處理過程中發(fā)生的高溫氧化以及鋁在無水乙醇中的腐蝕等均屬于此類腐蝕。實(shí)際上單純的化學(xué)腐蝕是相當(dāng)少的，一些干燥介質(zhì)中如混人水分常會(huì)由化學(xué)腐蝕轉(zhuǎn)化為電化學(xué)腐蝕。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 電化學(xué)腐蝕是指金屬與電解質(zhì)溶液發(fā)生電化學(xué)反應(yīng)而產(chǎn)生的破壞，反應(yīng)過程均包括陽極反應(yīng)和陰極反應(yīng)兩個(gè)過程，腐蝕過程中伴有電流的流動(dòng)，即電子和離子的運(yùn)動(dòng)。金屬在酸、堿、鹽等化學(xué)溶液和土壤、海水、潮濕的大氣中的腐蝕均屬于此類腐蝕。通常情況下，電化學(xué)腐蝕要比化學(xué)腐蝕強(qiáng)烈得多，金屬的腐蝕破壞大多數(shù)也是由電化學(xué)腐蝕引起的。 </p> <p> <br /> </p> <p> <br /> 無效的泵運(yùn)轉(zhuǎn)常是氣干擾造成的，可通過聲波液面測(cè)量和示功圖進(jìn)行診斷。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

螺桿泵必須按規(guī)定的方向工作，以產(chǎn)生一定的吸力和流量。在工作時(shí)，應(yīng)檢查壓力、溫度和機(jī)械密封。對(duì)于軸封，應(yīng)有輕微泄漏。如果泄漏量不超過20-30秒/滴，則認(rèn)為是正常的。如果螺桿泵在工作中產(chǎn)生噪聲，則經(jīng)常是由于油溫度低、油粘度高、油中空氣、耦合損失和泵的過度磨損造成的。 </p> <p> <br /> </p> <p> 3、單螺桿泵停車 </p> <p> 螺桿泵停止后，首先關(guān)閉排氣停止閥，關(guān)閉泵后關(guān)閉吸入截止閥。由于螺桿長(zhǎng)度大，剛性差，螺桿泵容易產(chǎn)生彎曲，造成異常工作，軸系統(tǒng)的連接必須良好，中間工作比較好是在安裝和定位后進(jìn)行，避免管路連接。應(yīng)引起變形，連接管應(yīng)**固定，盡可能減少泵的連接等，另外，備用螺絲比較好在存放期間懸掛和固定，以避免因放置不均勻引起的變形。
