單級水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)通常(chang)用于(yu)造(zao)(zao)(zao)(zao)紙(zhi)廠，以提供全(quan)方(fang)(fang)位的(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)能力。現代造(zao)(zao)(zao)(zao)紙(zhi)機(ji)使用真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)輔(fu)助造(zao)(zao)(zao)(zao)紙(zhi)脫水(shui)(shui)，因(yin)此真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)系(xi)統(tong)是(shi)(shi)造(zao)(zao)(zao)(zao)紙(zhi)機(ji)的(de)(de)重要(yao)組成部分。 隨著(zhu)酸性造(zao)(zao)(zao)(zao)紙(zhi)向中性造(zao)(zao)(zao)(zao)紙(zhi)的(de)(de)發(fa)展(zhan)，造(zao)(zao)(zao)(zao)紙(zhi)水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)結垢(gou)(gou)(gou)成為每(mei)個造(zao)(zao)(zao)(zao)紙(zhi)企業經常(chang)遇(yu)(yu)到的(de)(de)問題。無論(lun)是(shi)(shi)在南部還是(shi)(shi)北部形成，它都不(bu)(bu)是(shi)(shi)立即生成的(de)(de)，而是(shi)(shi)結的(de)(de)過(guo)程(cheng)。氧化(hua)皮(pi)的(de)(de)生產，其對造(zao)(zao)(zao)(zao)紙(zhi)機(ji)的(de)(de)影響正在逐(zhu)漸顯現，因(yin)此，從一(yi)開始就不(bu)(bu)能掉以輕心(xin)，要(yao)始終如(ru)一(yi)地防止(zhi)氧化(hua)皮(pi)的(de)(de)控制，這將具有長(chang)期(qi)的(de)(de)利益(yi)。 (1)水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)結垢(gou)(gou)(gou)的(de)(de)原因(yin)： 1.水(shui)(shui)質影響：高(gao)ph值和高(gao)硬度。 2.造(zao)(zao)(zao)(zao)紙(zhi)水(shui)(shui)的(de)(de)增白程(cheng)度增加，不(bu)(bu)溶物含量高(gao)，并(bing)(bing)且(qie)(qie)垢(gou)(gou)(gou)離子積累。 3.大量填充(chong)物。 4.溫度：水(shui)(shui)溫升高(gao)，冷卻系(xi)統(tong)使用不(bu)(bu)充(chong)分。 5水(shui)(shui)循環系(xi)統(tong)沒有定期(qi)的(de)(de)清(qing)(qing)潔(jie)和維護，這將增加造(zao)(zao)(zao)(zao)紙(zhi)水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)結垢(gou)(gou)(gou)的(de)(de)可能性。 (2)水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)對造(zao)(zao)(zao)(zao)紙(zhi)的(de)(de)不(bu)(bu)利影響 1.嚴重降(jiang)(jiang)低(di)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)度和抽氣(qi)量。 2.電(dian)動(dong)(dong)機(ji)電(dian)流(liu)上(shang)升，導致(zhi)(zhi)(zhi)功耗增加。 3.經常(chang)導致(zhi)(zhi)(zhi)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)卡(ka)住，難以啟動(dong)(dong)，造(zao)(zao)(zao)(zao)紙(zhi)機(ji)停(ting)止(zhi)并(bing)(bing)且(qie)(qie)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)不(bu)(bu)敢停(ting)止(zhi)。 4.頻繁的(de)(de)酸洗(xi)或手動(dong)(dong)拆卸(xie)不(bu)(bu)僅會損壞設(she)備(bei)，還會破(po)壞設(she)備(bei)的(de)(de)精度，導致(zhi)(zhi)(zhi)形成真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)或降(jiang)(jiang)低(di)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)度。 (3)水(shui)(shui)環真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)解決方(fang)(fang)案 長(chang)期(qi)以來，傳統(tong)的(de)(de)清(qing)(qing)潔(jie)方(fang)(fang)法(fa)(例如(ru)機(ji)械方(fang)(fang)法(fa)(刮擦，刷牙)，高(gao)壓水(shui)(shui)，化(hua)學清(qing)(qing)潔(jie)(酸洗(xi))等)在清(qing)(qing)潔(jie)設(she)備(bei)時會遇(yu)(yu)到許多問題：無法(fa)完全(quan)清(qing)(qing)除積垢(gou)(gou)(gou)，例如(ru)水(shui)(shui)垢(gou)(gou)(gou)，酸腐蝕會導致(zhi)(zhi)(zhi)設(she)備(bei)腐蝕。殘(can)留酸可能會導致(zhi)(zhi)(zhi)材料發(fa)生二次腐蝕或水(shui)(shui)垢(gou)(gou)(gou)腐蝕，從而可能導致(zhi)(zhi)(zhi)設(she)備(bei)更換。另外，清(qing)(qing)潔(jie)廢(fei)液(ye)是(shi)(shi)有毒(du)...

水環真空泵一直非常關注粗糙真空的獲得，例如真空過濾，真空水轉移，真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源，有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝，以減小彎頭或蝸殼，使水口面向水池。 2.縮短水環真空泵管道，拆除1米長的鋼管，并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如，將15米長的4米長水管替換為15厘米長的管道，并節省10公斤柴油10小時。 4.如果可以保持進水清潔，則可以卸下水環真空泵過濾器。 5.更換水環真空泵口環，調整軸向間隙，以防止葉輪口環和軸向間?
