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滑油、潤滑脂、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 /> 性能優(yōu)良螺桿泵收購價(jià)污泥螺桿泵工作時(shí)，液體被吸入后就進(jìn)入螺紋與泵殼所圍的密封空間。</p><div style="width:100%;text-align: center;"><img

國內(nèi)生產(chǎn)的大都仿制進(jìn)口產(chǎn)品，產(chǎn)品質(zhì)量良莠不齊，在選用國內(nèi)生產(chǎn)的產(chǎn)品時(shí)，在考慮其性價(jià)比的時(shí)候，選用低轉(zhuǎn)速，長導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良，額定壽命長的產(chǎn)品。 </p> <p> <br /> </p> <p> <br /> </p><p> 3、診斷低能效井。診斷的方法是確定抽油系統(tǒng)的總效率,而確定總效率只需測量輸入原動(dòng)機(jī)的功率、測定井底生產(chǎn)壓力和精確的生產(chǎn)測試數(shù)據(jù)。一般抽油系統(tǒng)的總效率應(yīng)為50％左右,若低于此應(yīng)提高其性能。提高總效率的技術(shù)包括保持高容積效率(泵的規(guī)格與井筒注入量匹配、消除氣干擾、用抽空控制器或定時(shí)器控制抽油)和換掉過大的電動(dòng)機(jī)。 </p> <p> <br /> </p> <p> 4、井下氣分離。無效的泵運(yùn)轉(zhuǎn)常是氣干擾造成的，可通過聲波液面測量和示功圖進(jìn)行診斷。比較好是將泵吸入口置于流體進(jìn)入層段的下方，若置于上方則應(yīng)使用氣體分離器。若閥座短節(jié)布置于流體進(jìn)入層段底部以下至少10ft，則在環(huán)空中可發(fā)生有效氣分離，此時(shí)套管起分離器外筒的作用。但井的條件常不容許將泵置于流體進(jìn)入層下方，則考慮用井下氣分離器。常規(guī)的氣分離器由流體進(jìn)入部分(如射孔短節(jié))、外筒(如底部有堵頭的一節(jié)油管)和泵底部的封液管組成。在泵的吸入口和排出口之間，就會(huì)被分隔成一個(gè)或多個(gè)密封空間。</p><div

給大家介紹螺桿泵保養(yǎng)技巧： </p> <p> 1、經(jīng)常加脂，電動(dòng)油桶泵為高速運(yùn)轉(zhuǎn)，潤滑脂易于揮發(fā)，故必須使軸承處的潤滑能保持清潔，并注意添換。 </p> <p> 2、螺桿泵經(jīng)常檢查維修，電動(dòng)油桶泵應(yīng)經(jīng)常檢查，維修，須檢查電源線：內(nèi)接線，插頭，開關(guān)是否良好，絕緣電阻是否正常，刷尾座是事松動(dòng)，換向器與電刷接觸良好，電樞繞級(jí)擴(kuò)定子繞組是否是有適中斷路現(xiàn)象，軸承及轉(zhuǎn)動(dòng)零件是否的損壞等等。 </p> <p> 3、注意保存電動(dòng)抽油泵應(yīng)放于干燥，清潔和沒有腐蝕性氣體的環(huán)境中。 </p> <p> 4、保存好每零件和調(diào)換相同零件，在拆檢螺桿泵時(shí)，應(yīng)保存好每個(gè)零件，要特別注意隔爆零件的隔爆面不能使其損傷拉毛包括絕緣襯墊及套管，如有損壞，必須調(diào)換上新的相同零件，不得采用低于原材料性能的代用材料或原有規(guī)格不符的零件，裝配時(shí)應(yīng)將所有零件按原先位置裝好，不能遺漏。 </p> <p> 5、螺桿泵注意絕緣電阻，長期擱置不用的或在潮濕環(huán)境中使用的電動(dòng)抽液泵，使用前必須用500伏兆歐表測量繞組的絕緣電阻。如繞組與電機(jī)殼間絕緣電阻小于7兆歐時(shí)，必須對繞組進(jìn)行干燥處理。 </p> <p> <br />
