點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開始，***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，云浮螺桿泵口碑推薦，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，云浮螺桿泵口碑推薦，云浮螺桿泵口碑推薦，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)，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 /> 主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。云浮螺桿泵口碑推薦</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云浮螺桿泵口碑推薦,螺桿泵"

3、螺桿泵的螺桿在機(jī)筒內(nèi)轉(zhuǎn)動(dòng)，物料與二者的摩擦，使螺桿與機(jī)筒的工作表面逐漸磨損：螺桿直徑逐漸縮小，機(jī)筒的內(nèi)孔直徑逐漸加大。這樣，螺桿與機(jī)筒的配合直徑間隙，隨著二者的逐漸磨損而一點(diǎn)點(diǎn)加大?？墒牵捎跈C(jī)筒前面機(jī)頭和分流板的阻力沒有改變，這就增加了被擠塑物料前進(jìn)時(shí)的漏流量，即物料從直徑間隙處向進(jìn)料方向流動(dòng)量增加。結(jié)果使塑膠機(jī)械生產(chǎn)量下降。這種現(xiàn)象又使物料在機(jī)筒內(nèi)停留時(shí)間增加，造成物料分解。如果是聚乙烯，分解產(chǎn)生的氯化氫氣體加強(qiáng)了對(duì)螺桿和機(jī)筒的腐蝕。 </p> <p> <br /> </p> <p> 4、物料中如有碳酸鈣和玻璃纖維等填充料，能加快螺桿和機(jī)筒的磨損。 </p> <p> <br /> </p> <p> 5、由于物料沒有塑化均勻，或是有金屬異物混入料中，使螺桿轉(zhuǎn)動(dòng)扭矩力突然增加，這種扭矩超出螺桿的強(qiáng)度極限，使螺桿扭斷。這是一種非常規(guī)***損壞。 </p> <p> <br />

螺桿泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干摩擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機(jī)完好，格柵暢通是螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之一，為此，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置，當(dāng)發(fā)生斷料時(shí)，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會(huì)產(chǎn)生真空，真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。五、保持恒定的出口壓力 </p> <p> <br /> </p> <p> 螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會(huì)逐漸升高，以至于超過預(yù)定的壓力值。此時(shí)電機(jī)負(fù)荷急劇增加。傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值，嚴(yán)重時(shí)會(huì)發(fā)生電機(jī)燒毀、傳動(dòng)零件斷裂。為了避免螺桿泵損壞，一般會(huì)在螺桿泵出口處會(huì)安裝回油閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。

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>

</p> <p> <br /> </p> <p> A：當(dāng)計(jì)量螺桿泵的進(jìn)口壓力大于出口壓力的時(shí)候，必須加裝背壓閥，否則，進(jìn)口壓力會(huì)將計(jì)量螺桿泵單向閥內(nèi)的球頂開，起不到密封的效果，這臺(tái)螺桿泵是失效了，我們稱該現(xiàn)象為虹吸現(xiàn)象。 </p> <p> <br /> </p> <p> Q：計(jì)量螺桿泵調(diào)節(jié)在多少范圍內(nèi)重復(fù)精度可達(dá)正負(fù)1%？ </p> <p> <br /> </p> <p> A：計(jì)量螺桿泵在10%-90%的調(diào)節(jié)范圍內(nèi)，能達(dá)到正負(fù)1%的重復(fù)精度。 </p> <p> <br /> </p> <p>

</p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （1）關(guān)閉排水管路上的閥門，以降低啟動(dòng)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(nèi)灌水，同時(shí)用手轉(zhuǎn)動(dòng)聯(lián)軸器，使葉輪內(nèi)殘存的空氣盡可能排出，直至放氣旋塞有水冒出時(shí)，再將其關(guān)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(shí)，應(yīng)關(guān)閉放氣旋塞及真空表和壓力表的旋塞，以保護(hù)儀表的準(zhǔn)確性。 3.啟動(dòng) </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 完成以上準(zhǔn)備工作后，便可啟動(dòng)螺桿泵。啟動(dòng)后待水螺桿泵轉(zhuǎn)速穩(wěn)定，電流表指針擺動(dòng)到指定位置，這時(shí)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(jìn)人正常運(yùn)行。與此同時(shí)還應(yīng)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(dòng)后空轉(zhuǎn)時(shí)間不能太長，通常以2～4min為限，如果時(shí)間過長，水的溫度就會(huì)升高，可能導(dǎo)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 />

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滑作用。 </p> <p> 目前，國內(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)子之間壓力過大 </p> <p> <br /> </p> <p> 在實(shí)際螺桿泵的運(yùn)動(dòng)過程中，橡膠襯套與轉(zhuǎn)子之間處于過盈狀態(tài)，充分利用過盈接觸，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>
