class="title">詳細(xì)說明</p><div id="3plb9tp" class="box"><p><p> 點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開始，豪華螺桿泵廠家電話地址，***產(chǎn)生凹坑，凹坑可能會(huì)被腐蝕產(chǎn)物覆蓋，結(jié)成瘤狀形的硬疤，疤的下面就是一個(gè)點(diǎn)蝕坑。點(diǎn)蝕經(jīng)常發(fā)生在金屬表面上有停滯或緩慢流動(dòng)介質(zhì)的區(qū)域。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 晶間腐蝕先從金屬表面晶粒之間的邊緣開始，豪華螺桿泵廠家電話地址，腐蝕介質(zhì)逐步滲人到金屬的深處，破壞了金屬晶粒之間的結(jié)合力，在金屬表面不會(huì)留下宏觀的跡象，從表面不易發(fā)現(xiàn)，但金屬材料的強(qiáng)度和塑性幾乎完全喪失，只要在很小的外力作用下就可能破壞。比如，不銹鋼經(jīng)過嚴(yán)重晶間腐蝕后，表面看起來仍十分光滑，但只要用錘輕輕敲擊，它就會(huì)碎成粉末。由于設(shè)備在工作過程中晶間腐蝕不容易被發(fā)現(xiàn)，豪華螺桿泵廠家電話地址，所以它是一種危險(xiǎn)性比較大的腐蝕破壞形式。 </p> <p> <br /> </p> <p> <br /> 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。豪華螺桿泵廠家電話地址</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

螺桿泵是否要配置安全閥？好處有哪些，選購螺桿泵的時(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:長期以來螺桿泵為了防止泵過載引起的破壞，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題困擾的客戶。

***腐蝕也稱為均勻腐蝕，它的特點(diǎn)是腐蝕均勻地發(fā)生在整個(gè)金屬的表面，腐蝕的結(jié)果是設(shè)備壁厚的均勻減薄。***腐蝕容易被發(fā)現(xiàn)和測量，因此這種臠蝕的危險(xiǎn)性較小，只要在螺桿泵的設(shè)計(jì)時(shí)考慮足夠的腐蝕裕量就可以保證螺桿泵的機(jī)械強(qiáng)度和*吏用壽命。 </p> <p> <br /> </p> <p> 局部腐蝕又稱為非均勻腐蝕，它的特點(diǎn)是腐蝕集中在金屬表面的一定區(qū)域，而其他區(qū)域不腐蝕或腐蝕很輕微。這類腐蝕又包括區(qū)域腐蝕、點(diǎn)腐蝕、晶間腐蝕、應(yīng)力腐蝕、腐蝕疲勞和空泡腐蝕等。 </p> <p> <br /> </p> <p> <br /> </p><p> G型單螺桿泵螺桿軸磨損原因分析，G型單螺桿泵螺桿軸磨損五點(diǎn)原因： </p> <p> 1、每種塑料，都有一個(gè)理想塑化的加工溫度范圍，應(yīng)該控制料筒加工溫度，使之接近這個(gè)溫度范圍。粒狀塑料從料斗進(jìn)入料筒，首先會(huì)到達(dá)加料段，在加料段必然會(huì)出現(xiàn)干性磨擦，當(dāng)這些塑料受熱不足，熔融不均時(shí)，很易造成料筒內(nèi)壁及螺桿表面磨損增大。同樣，在壓縮段和均化段，如果塑料的熔融狀態(tài)紊亂不均，也會(huì)造成磨損增快。2、轉(zhuǎn)速應(yīng)調(diào)校得當(dāng)。由于部分塑料加有強(qiáng)化劑，如玻璃纖維、礦物質(zhì)或其他填充料。這些物質(zhì)對金屬材質(zhì)的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時(shí)，如果用高的轉(zhuǎn)速成，則在提高對塑料的剪切力的同時(shí)，亦將令強(qiáng)化相應(yīng)地產(chǎn)生更多被撕碎的纖維，被撕碎的纖維含有鋒利末端，令磨損力大為增加。無機(jī)礦物質(zhì)在金屬表面高速滑行時(shí)，其刮削作用也不小。所以轉(zhuǎn)速不宜調(diào)得太高。 </p> <p> <br /> 由于螺桿是等速旋轉(zhuǎn)，所以液體出流流量也是均勻的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="豪華螺桿泵廠家電話地址,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876904726562/9106620.jpg"></div><p> 沖蝕磨損 </p> <p> 沖蝕磨損又名侵蝕磨損，這種磨損的出現(xiàn)是由于螺桿泵轉(zhuǎn)子和定子之間液流，這種磨損在螺桿泵正常運(yùn)行時(shí)是主要的磨損形式之一。 </p> <p> 摩擦磨損 </p> <p> 這種情況只在摩擦因數(shù)很大但是橡膠的撕裂強(qiáng)度很低的條件下發(fā)***生這種磨損時(shí)會(huì)造成橡膠表層被撕裂、卷曲、拉伸，**終從橡膠表層脫落，形成卷曲的橡膠碎屑。如果螺桿泵發(fā)生干摩擦轉(zhuǎn)子與定子摩擦發(fā)熱，使橡膠溫度升高，降低橡膠的撕裂強(qiáng)度，使橡膠表層樹脂老化、發(fā)黏，從而使摩擦磨損加劇，定子迅速損壞，這也就是為什么螺桿泵不能空轉(zhuǎn)。 </p> <p> 以上四種磨損情況網(wǎng)王同時(shí)發(fā)生，只是在不同的工況下會(huì)以某種磨損形式為主。因此，認(rèn)為應(yīng)當(dāng)針對丁腈橡膠磨粒磨損、沖蝕磨損、疲勞磨損的規(guī)律，設(shè)計(jì)合理的螺桿泵結(jié)構(gòu)，使定子的磨損率降到比較低，從而延長其使用壽命。 </p> <p> <br /> 使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本。豪華螺桿泵廠家電話地址</p><p style="text-indent:25px">單螺桿泵體積小，重量輕、噪聲低，結(jié)構(gòu)簡單，維修方便.豪華螺桿泵廠家電話地址</p><p> G型單螺桿泵故障與排除，一、啟動(dòng)困難： </p> <p> 原因：1. 料液未充滿泵腔.摩擦阻力較大；2.
