<p> 經過***檢查，確認一切正常后，才可作啟動的準備工作。應有以下幾項工作。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （1）關閉排水管路上的閥門，以降低啟動電流； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （2）打開放氣旋塞，向水螺桿泵內灌水，同時用手轉動聯(lián)軸器，使葉輪內殘存的空氣盡可能排出，直至放氣旋塞有水冒出時，再將其關閉； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （3）大型水螺桿泵用真空螺桿泵抽氣灌水時，應關閉放氣旋塞及真空表和壓力表的旋塞，以保護儀表的準確性。 3.啟動 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 完成以上準備工作后，便可啟動螺桿泵。啟動后待水螺桿泵轉速穩(wěn)定，電流表指針擺動到指定位置，這時再把真空表及壓力表的旋塞打開，并慢慢開啟出口閥門，水螺桿泵進人正常運行。與此同時還應將水封管的閥門打開。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 螺桿泵啟動后空轉時間不能太長，通常以2～4min為限，如果時間過長，水的溫度就會升高，可能導致汽蝕現(xiàn)象或其他不良后果。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 試運轉 </p> <p> 1、污泥螺桿泵切忌干運轉，哪怕很短時間空轉也會造成定子的損壞。 </p> <p> 在啟動泵前，先將要輸送的介質注入泵的吸入腔內(若介質濃度高，稀釋后注入)。以確保潤滑橡膠定子。泵停止運轉時，應留有足夠的介質在吸入腔內。用記在設計管道時應予以專門考慮。 </p> <p> 2、污泥螺桿泵不能在閥門關閉時工作，以避免容積泵的壓力急劇升高而造成管道破裂及泵的損壞。尤其在輸送危險介質時，安裝壓力開關等安全裝置是尤其重要的。 </p> <p> 3、泵應瞬時通電，確認泵的轉身與所示的方向相同。 </p> <p> 4、啟動前，再一次檢查，多種管道閥門的開啟關閉情況。無誤時，方可開機。 </p> <p> 5、輸送易沉淀，易固化介質，應定期清洗泵及管線。 </p> <p> 6、對已存放二年以上的泵，應對泵內所有的橡膠進行更換(包括定子)，發(fā)確保泵的運轉正常及安全，從而延長泵的使用壽命。 </p> <p> 維護與保養(yǎng) </p> <p> <br /> 重新裝泵前，應做好各項更換、維修的準備工作。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣東豪華螺桿泵,螺桿泵"

<p> 式中Qth為實踐排量，m3÷d；e為公平距，mm；D為轉子截面直徑，mm；T為定子導程，mm；n為轉子轉速，r÷min。 </p> <p> <br /> </p> <p> 螺桿泵的實踐排量為： </p> <p> <br /> </p> <p> 式中，Q為實踐排量，m3÷d；Gv為容積效力，％。上述兩式中公平距、轉子截面直徑D、定子導程T都是螺桿泵的構造參數。構造參數肯定后，螺桿泵的實踐排量就只與轉速n和容積效力Gv有關，而容積效力重要與泵的外部走漏量有關，也即與定子和轉子的配合間隙（過盈）以及所舉升介質的粘度有關。 </p> <p> <br /> </p> <p> <br /> 是按迥轉嚙合容積式原理工作的新型泵種。廣東螺桿泵生產工藝</p><p style="text-indent:25px">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。廣東豪華螺桿泵</p><p> 單螺桿泵是一種單螺桿式輸運泵，它的主要工作部件是偏心螺旋體的螺桿（稱轉子）和內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電動機帶動泵軸轉動時，螺桿一方面則繞本身的軸線旋轉，另一方面它又沿襯套內表面滾動，這樣便會形成泵的密封腔室。螺桿每轉一周，密封腔內的液體向前推進一個螺距，隨著螺桿的連續(xù)轉動，液體螺旋形方式從一個密封腔壓向另一個密封腔，***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、潤滑脂、泥漿、黏土、陶土等介質的傳送。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螺桿由原動機驅動，主動螺桿與從動螺桿具有不同旋向的螺紋，螺桿與泵體緊密貼合，從動螺桿是通過同步齒輪由主動螺桿帶動的。泵內吸入室應與排出室嚴密地隔開，因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應盡可能小些，同時螺桿與泵體、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滑油、潤滑脂、原油、柏油、燃料油及其他高黏度油等介質的傳送。 </p> <p> <br /> </p> <p> <br /> 廣東豪華螺桿泵</p><p
