style="text-indent:25px">單螺桿泵、污泥螺桿泵、濃漿泵是一種正排量泵，它利用一個(gè)或多個(gè)螺旋，沿螺桿軸移動(dòng)流體或固體。其**簡(jiǎn)單的形式（阿基米德螺桿泵）中，一個(gè)單螺桿在一個(gè)圓柱形的空腔中旋轉(zhuǎn)，從而沿著螺桿的主軸移動(dòng)物料。這個(gè)古老的機(jī)械仍然是用在許多低技術(shù)的應(yīng)用，如用于運(yùn)輸糧食和其他固體農(nóng)業(yè)機(jī)械灌溉系統(tǒng)。單螺桿泵正是基于這種結(jié)構(gòu)研發(fā)的新型泵種。特點(diǎn)是流量平穩(wěn)、壓力脈動(dòng)小、有一定自吸能力、噪聲低、效率高、壽命長(zhǎng)、工作可靠；由于定子選用彈性材料，所以這種螺桿泵可以用于高粘度流體的輸送和含有硬質(zhì)懸浮顆粒介質(zhì)或含有纖維介質(zhì)的輸送，能勝任其他泵型不能適應(yīng)的作條件，中山螺桿泵生產(chǎn)廠商，中山螺桿泵生產(chǎn)廠商。其流量與轉(zhuǎn)速成正比。而其突出的優(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，中山螺桿泵生產(chǎn)廠商，可輸送高粘度介質(zhì)。輸送高粘度介質(zhì)：根據(jù)泵的大小不同可以輸送粘度從厘泊的介質(zhì)。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。</p><div

點(diǎn)腐蝕是由局部電作用引起的，腐蝕從金屬表面開(kāi)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(kāi)始，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(guò)嚴(yán)重晶間腐蝕后，表面看起來(lái)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(guò)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。

式中，Gv為容積效力，％；Qin為額外壓力點(diǎn)規(guī)則轉(zhuǎn)速下的體積流量，m3÷h；Qon為零壓力點(diǎn)規(guī)則轉(zhuǎn)速下的體積流量，m3÷h。 </p> <p> 對(duì)螺桿泵實(shí)踐排量提出了明白的判斷方式和盤算公式。 </p> <p>
