id="sc292b7" class="box"><p><p> 通過減速機構(gòu)或無級調(diào)速機構(gòu)來降低轉(zhuǎn)速，使其轉(zhuǎn)速保持在每分三百轉(zhuǎn)以下較為合理的范圍內(nèi)，與高速運轉(zhuǎn)的螺桿泵相比，使用壽命能延長幾倍，佛山豪華螺桿泵。 </p> <p> <br /> </p> <p> 二、污泥螺桿泵的品質(zhì) </p> <p> <br /> </p> <p> 現(xiàn)在市場上的污泥螺桿泵的種類較多，相對而言，進口的污泥螺桿泵設(shè)計合理，材質(zhì)精良，但價格較高，服務方面有的不到位，配件價格高，訂貨周期長，可能影響生產(chǎn)的正常運行。 </p> <p> <br /> </p> <p> 國內(nèi)生產(chǎn)的大都仿制進口產(chǎn)品，產(chǎn)品質(zhì)量良莠不齊，佛山豪華螺桿泵，在選用國內(nèi)生產(chǎn)的產(chǎn)品時，在考慮其性價比的時候，選用低轉(zhuǎn)速，佛山豪華螺桿泵，長導程，傳動量部件材質(zhì)優(yōu)良，額定壽命長的產(chǎn)品。 </p> <p> <br /> </p> <p> <br /> </p><div

G型單螺桿泵如何選擇適合型號? </p> <p> 螺桿泵型號的選型首先得確定螺桿泵所輸送的液體介質(zhì)具體是什么，里面所含有哪些化學成分以便確定選擇合適橡膠套滿足工況，列入家具行業(yè)輸送油漆，客戶只提供輸送油漆，得了解清楚油漆里面是否含有甲苯，如含有甲苯得選用氟橡膠材質(zhì)的橡膠套才能滿足工況，不然選擇普通的丁晴橡膠套很容易壞掉，用戶不了解的情況下誤認為是廠家質(zhì)量的問題所致，還有介質(zhì)的粘度及比重，如粘度大或者介質(zhì)含固量大的物料，要在普通轉(zhuǎn)速的基礎(chǔ)上降低螺桿泵的轉(zhuǎn)速，轉(zhuǎn)速低磨損就會降低，所以螺桿泵型號的選型及為重要。1級螺桿泵：比較高工作壓力為0.6 MPa； </p> <p> 2級螺桿泵：比較高工作壓力為1.2 MPa； </p> <p> 3級螺桿泵：比較高工作壓力為1.8Mpa； </p> <p> 4級螺桿泵：比較高工作壓力為2.4 MPa； </p> <p> 由于螺桿泵輸送介質(zhì)情況不同，對于含有嚴重磨損性的介質(zhì)，請參照表一選擇襯套級數(shù)。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="佛山豪華螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876900634765/2986980.jpg"></div><p style="text-indent:25px">螺桿泵的腐蝕與防護，螺桿泵輸送的液體種類很多，液體的性質(zhì)和螺桿泵的操作條件也是千差萬別的，如液體的溫度可高達幾百度，壓力可達幾十兆帕，有的介質(zhì)呈酸性，有的介質(zhì)呈堿性?有的介質(zhì)腐蝕性強，有的介質(zhì)腐蝕性弱等。為了滿足以上要求，除了采用不同類型的螺桿泵以外，還要了解不同的液體在各種條件下對金屬材料的腐蝕情況，從而針對不同的液體來選擇合適的耐腐蝕螺桿泵用于各類化工生產(chǎn)工藝流程中去，并且采取相應的防腐措施以延長螺桿泵的使用壽命，這也是石油化工用螺桿泵的一個非常重要的問題。多數(shù)螺桿泵是由金屬材料制造的，金屬材料腐蝕的規(guī)律比較復雜，不同的材料在同一種介質(zhì)中的腐蝕情況各不相同，同一種材料在不同介質(zhì)中的腐蝕情況也大相徑庭，比如碳鋼在稀***中腐蝕速度很快，但在濃***中卻相當穩(wěn)定；普通的18-8型奧氏體不銹鋼能耐硝酸、冷磷酸、許多鹽類及堿溶液、水和蒸汽、石油產(chǎn)品等化學介質(zhì)的腐蝕，但是對***、鹽酸、氫氟酸、鹵素、草酸等的化學穩(wěn)定性比較差；鋁在稀***和發(fā)煙***中穩(wěn)定，在中等和高濃度的***中卻不穩(wěn)定。因此，必須首先了解金屬腐蝕的原因和種類，才能針對特定的化工物料，正確選用合適的耐腐蝕螺桿泵并采取合理的防腐措施。</p><div
