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，汕頭官方螺桿泵、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，汕頭官方螺桿泵，出現(xiàn)腐蝕；銅電極成為腐蝕電池的陰極而被保護(hù)，汕頭官方螺桿泵，溶液中的H＋不斷移動(dòng)到銅電極上得到電子而析出H2。

1、經(jīng)常加脂，電動(dòng)油桶泵為高速運(yùn)轉(zhuǎn)，潤(rùn)滑脂易于揮發(fā)，故必須使軸承處的潤(rùn)滑能保持清潔，并注意添?yè)Q。 </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(méi)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(zhǎng)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(cè)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(duì)繞組進(jìn)行干燥處理。 </p> <p> <br /> 云浮螺桿泵高性價(jià)比選擇單螺桿泵流量均勻壓力穩(wěn)定，低轉(zhuǎn)速時(shí)更為明顯.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="汕頭官方螺桿泵,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900957031/888996.jpg"></div><p> G型螺桿泵的橡膠套又名定子，橡膠套內(nèi)壁是橡膠材料制作而成，由于橡膠套與轉(zhuǎn)子（螺桿）之間間隙較小，所以G型單螺桿泵是***禁止空轉(zhuǎn)，必須要有液體使橡膠套與螺桿軸之間有潤(rùn)滑作用。 </p> <p> 目前，國(guó)內(nèi)很多螺桿泵廠家選擇使用新材料改善設(shè)備整體性能，延長(zhǎng)螺桿泵設(shè)備使用壽命，但是，從設(shè)備密封性能整體情況來(lái)看，螺桿泵密封性能故障存在很多影響因素，具體表現(xiàn)在以下幾個(gè)方面: </p> <p> 1、橡膠襯套與轉(zhuǎn)子之間壓力過(guò)大 </p> <p> <br /> </p> <p> 在實(shí)際螺桿泵的運(yùn)動(dòng)過(guò)程中，橡膠襯套與轉(zhuǎn)子之間處于過(guò)盈狀態(tài)，充分利用過(guò)盈接觸，這樣能夠比較大的減少流體漏失。但是，當(dāng)螺桿泵受到內(nèi)壁壓力、密封腔室間壓差等因素影響時(shí)，就會(huì)造成接觸壓力下降，從而產(chǎn)生泄漏，降低設(shè)備密封性。2、結(jié)構(gòu)參數(shù) </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> Q：計(jì)量螺桿泵自動(dòng)控制變頻電機(jī)+變頻器與通過(guò)自動(dòng)沖程控制器來(lái)實(shí)現(xiàn)的自動(dòng)控制區(qū)別在哪？ </p> <p> <br /> </p> <p> A：”2種方式**終結(jié)果都是調(diào)節(jié)螺桿泵的流量，區(qū)別就是，變頻電機(jī)+變頻器是通過(guò)改變電機(jī)頻率(轉(zhuǎn)速)，實(shí)現(xiàn)調(diào)節(jié)流量的效果；自動(dòng)沖程變速器是通過(guò)改變螺桿泵的行程(電機(jī)轉(zhuǎn)速不變)，實(shí)現(xiàn)現(xiàn)調(diào)節(jié)流量的效果?！?</p>

style="text-indent:25px">常見(jiàn)螺桿泵的特點(diǎn)和應(yīng)用，螺桿泵依靠螺桿相互嚙合（或螺桿與定子嚙合）空間的容積變化來(lái)輸送液體。當(dāng)螺桿轉(zhuǎn)動(dòng)時(shí)吸入腔一端作軸向移動(dòng)，使吸入腔的容積增大，壓力降低，液體在壓差作用下沿吸入管進(jìn)入吸入腔。隨著螺桿的轉(zhuǎn)動(dòng)，密封腔內(nèi)的液體連續(xù)而均勻地沿軸向移動(dòng)到排出腔，由于排出腔一端的容積逐漸縮小，即將液體排出。螺桿泵的特點(diǎn)是流量和壓力脈動(dòng)小、運(yùn)轉(zhuǎn)平穩(wěn)、噪聲低、效率高、壽命長(zhǎng)、有較強(qiáng)的自吸能力而且結(jié)構(gòu)簡(jiǎn)單緊湊；其突出的優(yōu)點(diǎn)是輸送介質(zhì)時(shí)不形成渦流、對(duì)介質(zhì)的粘性不敏感，可輸送高粘度介質(zhì)。螺桿泵按螺桿數(shù)目分為單螺桿泵、雙、三和五螺桿泵。單螺桿泵的結(jié)構(gòu)為單頭陽(yáng)螺旋轉(zhuǎn)子在特殊的雙頭陰螺旋定子內(nèi)偏心地轉(zhuǎn)動(dòng)（定子是柔性的），能沿泵中心線來(lái)回?cái)[動(dòng)，與定子始終保持嚙合；雙螺桿泵結(jié)構(gòu)為有兩根同樣大小的螺桿軸，一根為主動(dòng)軸，一根為從動(dòng)軸，通過(guò)齒輪傳動(dòng)達(dá)到同步旋轉(zhuǎn)；三螺桿泵結(jié)構(gòu)為有一根主動(dòng)螺桿和兩根與之相嚙合的從動(dòng)螺桿所構(gòu)成；五螺桿泵的結(jié)構(gòu)為定子內(nèi)裝有五根左、右旋的螺桿軸，螺桿的共軛齒廓上有一段漸開線，它起主動(dòng)螺桿泵向從動(dòng)螺桿傳遞運(yùn)動(dòng)的作用。單螺桿泵一泵多用可以輸送不同粘度的介質(zhì).惠州螺桿泵歡迎咨詢</p><p style="text-indent:25px">要求輸送壓力穩(wěn)定，介質(zhì)固有結(jié)構(gòu)不受破壞時(shí)，選用單螺桿泵輸送**為理想。汕頭官方螺桿泵</p><p> 螺桿泵是否要配置安全閥？好處有哪些，選購(gòu)螺桿泵的時(shí)候經(jīng)常困擾是否要給螺桿泵廢紙安全閥？到底有沒(méi)有必要？配置安全閥之后又有哪些好處呢？螺桿泵的一個(gè)重要特點(diǎn)是在泵的強(qiáng)度允許的情況下，其排出壓力取決于它的背壓。因此，當(dāng)螺桿泵運(yùn)行時(shí)，一旦排出管路堵塞或操作失誤未打開排出閥門等原因，排出壓力就會(huì)急劇升高，導(dǎo)致泵過(guò)載損壞。 </p> <p> 螺桿泵配置了安全閥就能使當(dāng)排出壓力超過(guò)某規(guī)定值時(shí)，安全閥在排出壓力作用下，開啟安全閥內(nèi)的閥，介質(zhì)就回流至泵的進(jìn)口端，從而使排出壓力回落，避免了排出壓力的進(jìn)一步升高，保護(hù)螺桿泵不被破壞。泵配置安全閥的原因:長(zhǎng)期以來(lái)螺桿泵為了防止泵過(guò)載引起的破壞，通常采用在泵上配置安全閥或在泵的出口管路上配囂安全閥的措施。以上就是答案，希望能夠幫助到被此問(wèn)題困擾的客戶。
