<p> 1、注意吸入管道密封，***啟動前應在吸入管道室中注滿潤滑性介質，并用管子鉗轉動數轉。然后啟動。嚴禁在沒有介質狀態(tài)下空轉，造成定子損壞。 </p> <p> 2、注意電機轉向，防止逆轉。 </p> <p> 3、使用中隨時注意泵的流量、壓力等狀況，如發(fā)現流量、壓力突然變化或有異聲，應及時檢查解決。 </p> <p> 4、對于高粘度、有結晶、含顆粒或有腐蝕性介質的泵，使用完畢后，應進行清洗，防止沉積或損壞。 </p> <p> 安裝 </p> <p> <br /> </p> <p> <br /> </p> <p> 1、注意污泥螺桿泵的傳動系統(tǒng)的同軸度，出廠前，泵及動力端(有的包括底座)已作調整。但在安裝時，由于基礎不平，擰緊地腳螺栓，可能造成底座扭曲，造成聯軸器中心偏移。應重新檢查聯軸器安裝偏差。 </p> <p> <br /> </p> <p> 2、出液口前應安裝一段長度略大于定子的易拆卸管線，以利于更換定子。 </p> <p> <br /> </p> <p> 3、泵的進口在垂直方向，***螺桿泵市場前景，出口在水平方向，這樣可使密封在負壓狀態(tài)工作，減小密封腔的壓力，旋向：從出口方向看逆時針旋轉。另外泵的進出口法蘭(管道)不應承受管道重量，所以管道應設支撐點。 </p> <p> <br /> </p> <p> 4、管道在安裝前必須清洗干凈，防止異物損壞定子，***螺桿泵市場前景、轉子，***螺桿泵市場前景，并造成堵塞。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />

我國螺桿泵**早是從20世紀60年開始引進生產的，比起國外螺桿泵技術的發(fā)展晚了近20年，但是隨著螺桿泵不斷在各行業(yè)發(fā)揮不可替代的作用，我國越來越重視螺桿泵的研制開發(fā)，國內螺桿泵在發(fā)展方面也取得了不少的成果。中國產業(yè)信息網發(fā)布的《2013-2017年中國螺桿泵市場調查及前景評估研究報告》指出我國目前螺桿泵生產廠家約40-50家，統(tǒng)計資料顯示，2012年我國螺桿泵行業(yè)整體產量達到21.35萬臺，同比2011年增長約13.35%。 </p> <p> 二、我國螺桿泵競爭趨勢分析 </p> <p> 從企業(yè)結構來看，目前我國螺桿泵市場價格分成三個梯度： </p> <p> <br /> 汕頭高質量螺桿泵特點是流量平穩(wěn)、壓力脈動小、有一定自吸能力、噪聲低、效率高、壽命長、工作可靠。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="***螺桿泵市場前景,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876905791015/1752868.jpg"></div><p> 第三梯度是國內企業(yè)產品。國內螺桿泵企業(yè)在技術上和品牌上處于劣勢，只能通過壓低價格、提高服務質量、減少交貨周期來贏得客戶，因而價格往往比進口螺桿泵要低20％－30％。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 從產品結構來看，螺桿泵產品種類較多，規(guī)格復雜，價格跨度較大。加上一些中小企業(yè)以低廉的價格進行惡性競爭，擾亂了市場價格。一般而言，原材料等級越高、產品規(guī)格越高的螺桿泵價格更高。分種類而言，三螺桿泵結構簡單，便于維修，價格也相對較低。雖然我國國內的螺桿泵與國外專業(yè)公司相比還存在差距，但隨著我國螺桿泵科研力量的投入及應用實踐的增多，螺桿泵未來發(fā)展趨勢是開發(fā)低轉速，長導程，傳動量部件材質優(yōu)良，額定壽命長的產品替代原來傳統(tǒng)螺桿泵。 </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原因： </p> <p> 1、每種塑料，都有一個理想塑化的加工溫度范圍，應該控制料筒加工溫度，使之接近這個溫度范圍。粒狀塑料從料斗進入料筒，首先會到達加料段，在加料段必然會出現干性磨擦，當這些塑料受熱不足，熔融不均時，很易造成料筒內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，也會造成磨損增快。2、轉速應調校得當。由于部分塑料加有強化劑，如玻璃纖維、礦物質或其他填充料。這些物質對金屬材質的磨擦力往往比熔融塑料的大得多。在注塑這些塑料時，如果用高的轉速成，則在提高對塑料的剪切力的同時，亦將令強化相應地產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。無機礦物質在金屬表面高速滑行時，其刮削作用也不小。所以轉速不宜調得太高。 </p> <p> <br /> 在輸送介質的進程中具有不受攪動、脈動小、無剪切等特點.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="***螺桿泵市場前景,螺桿泵" src="http://tyunfile.71360.com/UploadFile/qunxun/637211876904726562/9106620.jpg"></div><p> G型螺桿泵的橡膠套又名定子，橡膠套內壁是橡膠材料制作而成，由于橡膠套與轉子（螺桿）之間間隙較小，所以G型單螺桿泵是***禁止空轉，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，國內很多螺桿泵廠家選擇使用新材料改善設備整體性能，延長螺桿泵設備使用壽命，但是，從設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，具體表現在以下幾個方面: </p> <p> 1、橡膠襯套與轉子之間壓力過大 </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，當螺桿泵受到內壁壓力、密封腔室間壓差等因素影響時，就會造成接觸壓力下降，從而產生泄漏，降低設備密封性。2、結構參數 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 比較好是將泵吸入口置于流體進入層段的下方，若置于上方則應使用氣體分離器?？诒寐輻U泵誠信為本</p><p style="text-indent:25px">螺桿泵損失小，經濟性能好。***螺桿泵市場前景</p><p> 二、螺桿泵的轉速選用 </p> <p> <br /> </p> <p> 螺桿泵的流量與轉速成線性關系，相對于低轉速的螺桿泵，高轉速的螺桿泵雖然能增加了流量和揚程，但功率明顯增大，高轉速加速了轉子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉速螺桿泵的定轉子長度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p> 三、確保雜物不進入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會對螺桿泵的橡膠材質定子造成損壞，所以確保雜物不進入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機，也有的安裝格柵裝置或濾網，阻擋雜物進入螺桿泵，對于格柵應及時清撈以免造成堵塞。 </p> <p> <br /> ***螺桿泵市場前景</p><p
