螺桿泵的流量與轉(zhuǎn)速成線性關(guān)系，相對于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖然能增加了流量和揚程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p>

</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> 在實際螺桿泵的運動過程中，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，就會造成接觸壓力下降，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 /> 汕尾豪華螺桿泵單螺桿泵適合輸送敏性物品和易受離心力等破壞的物品.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="肇慶***螺桿泵,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876906972656/3705264.jpg"></div><p> 單螺桿泵是一種單螺桿式輸運泵，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)電動機帶動泵軸轉(zhuǎn)動時，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，這樣便會形成泵的密封腔室。螺桿每轉(zhuǎn)一周，密封腔內(nèi)的液體向前推進(jìn)一個螺距，隨著螺桿的連續(xù)轉(zhuǎn)動，液體螺旋形方式從一個密封腔壓向另一個密封腔，***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螺桿由原動機驅(qū)動，主動螺桿與從動螺桿具有不同旋向的螺紋，螺桿與泵體緊密貼合，從動螺桿是通過同步齒輪由主動螺桿帶動的。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 /> </p><p> ***梯度是進(jìn)口螺桿泵產(chǎn)品。由于國外企業(yè)具有品牌和技術(shù)上的優(yōu)勢，目前國內(nèi)許多客戶選擇購買從國外進(jìn)口的螺桿泵。由于運輸?shù)雀鞣N成本加上國外企業(yè)的定價往往較高，使得進(jìn)口螺桿泵價格居高不下。而且由于交貨期長，客戶要滿足生產(chǎn)則往往需要一次性購買較多產(chǎn)品，影響了企業(yè)資金周轉(zhuǎn)。 </p> <p> <br /> </p> <p> 第二梯度是在我國進(jìn)行生產(chǎn)銷售的合資企業(yè)和外資企業(yè)產(chǎn)品。這類企業(yè)具有技術(shù)上的優(yōu)勢，且在國內(nèi)生產(chǎn)，物流周期短，生產(chǎn)成本也得以降低，因而市場價格相對進(jìn)口產(chǎn)品也有所下調(diào)。 </p> <p> <br /> </p>

螺桿泵由于其結(jié)構(gòu)特點，大部分使用在輸送較高粘度的液體及含有顆粒的液體，因此其轉(zhuǎn)數(shù)的選擇非常關(guān)鍵，螺桿泵零件少，結(jié)構(gòu)緊湊，體積小，維修簡單，螺桿泵轉(zhuǎn)子和定子是螺桿泵的易損件，結(jié)構(gòu)簡單，便于裝拆。是按迥轉(zhuǎn)嚙合容積式原理工作的新型泵種。主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。采用***無味的食用橡膠，工作溫度可達(dá)120攝氏度，如果采用高溫120攝氏度—350攝氏度時可定制。由于該二部件的特殊幾何開頭分別形成單獨的密封容腔。介質(zhì)由軸向均勻推行流動。內(nèi)部流速代低，容積保持不變。螺桿泵壓力穩(wěn)定，因而不會產(chǎn)品渦流和攪動。每級泵的輸出壓力為0.6MPa—1.2MPa，揚程60m—120m（清水），自吸高度一般在3m以上。 </p> <p> 螺桿泵如何保持高效率 </p> <p> 如何保持螺桿泵高效率，螺桿泵的容量大于井的產(chǎn)量或泵吸入口處氣分離不好，一部分泵排量受氣干擾而損失，如果消除泵內(nèi)氣的干擾和控制泵的運轉(zhuǎn)時間，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。 </p> <p> <br /> 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。汕頭螺桿泵質(zhì)量代理商</p><p style="text-indent:25px">更換填料時，應(yīng)全部更換，軸若磨損嚴(yán)重也應(yīng)更換。肇慶***螺桿泵</p><p> 一、我國螺桿泵行業(yè)發(fā)展現(xiàn)狀 </p> <p>
