單級水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)通常(chang)(chang)用于造(zao)紙(zhi)廠，以(yi)(yi)提供全方(fang)(fang)位的(de)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)能(neng)力。現代造(zao)紙(zhi)機(ji)使用真(zhen)(zhen)(zhen)空(kong)(kong)(kong)輔助造(zao)紙(zhi)脫(tuo)水，因此(ci)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)系統是造(zao)紙(zhi)機(ji)的(de)重(zhong)(zhong)要組成(cheng)(cheng)部(bu)分。 隨著酸(suan)(suan)性造(zao)紙(zhi)向中性造(zao)紙(zhi)的(de)發(fa)展，造(zao)紙(zhi)水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)結(jie)垢(gou)(gou)(gou)(gou)成(cheng)(cheng)為(wei)每個造(zao)紙(zhi)企業經常(chang)(chang)遇(yu)到的(de)問題。無論是在南(nan)部(bu)還是北部(bu)形(xing)成(cheng)(cheng)，它都不是立即生成(cheng)(cheng)的(de)，而(er)(er)是結(jie)的(de)過程。氧化(hua)皮(pi)的(de)生產，其對(dui)造(zao)紙(zhi)機(ji)的(de)影(ying)(ying)響正在逐漸顯現，因此(ci)，從一開始就不能(neng)掉以(yi)(yi)輕心，要始終如一地防(fang)止氧化(hua)皮(pi)的(de)控(kong)制，這將(jiang)具有長(chang)期的(de)利益。 (1)水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)結(jie)垢(gou)(gou)(gou)(gou)的(de)原因： 1.水質影(ying)(ying)響：高ph值和高硬度。 2.造(zao)紙(zhi)水的(de)增白程度增加(jia)，不溶物(wu)含量(liang)高，并(bing)且垢(gou)(gou)(gou)(gou)離子積累。 3.大量(liang)填充(chong)物(wu)。 4.溫(wen)度：水溫(wen)升高，冷卻系統使用不充(chong)分。 5水循環(huan)(huan)系統沒有定期的(de)清(qing)潔(jie)和維護(hu)，這將(jiang)增加(jia)造(zao)紙(zhi)水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)結(jie)垢(gou)(gou)(gou)(gou)的(de)可能(neng)性。 (2)水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)對(dui)造(zao)紙(zhi)的(de)不利影(ying)(ying)響 1.嚴重(zhong)(zhong)降低真(zhen)(zhen)(zhen)空(kong)(kong)(kong)度和抽(chou)氣量(liang)。 2.電動機(ji)電流(liu)上升，導(dao)致(zhi)(zhi)功耗增加(jia)。 3.經常(chang)(chang)導(dao)致(zhi)(zhi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)卡住，難(nan)以(yi)(yi)啟動，造(zao)紙(zhi)機(ji)停(ting)止并(bing)且真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)不敢停(ting)止。 4.頻繁的(de)酸(suan)(suan)洗或手動拆(chai)卸不僅會(hui)損(sun)壞(huai)設(she)備，還會(hui)破壞(huai)設(she)備的(de)精度，導(dao)致(zhi)(zhi)形(xing)成(cheng)(cheng)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)或降低真(zhen)(zhen)(zhen)空(kong)(kong)(kong)度。 (3)水環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)解(jie)決方(fang)(fang)案(an) 長(chang)期以(yi)(yi)來，傳統的(de)清(qing)潔(jie)方(fang)(fang)法(例(li)如機(ji)械(xie)方(fang)(fang)法(刮擦，刷牙)，高壓水，化(hua)學清(qing)潔(jie)(酸(suan)(suan)洗)等)在清(qing)潔(jie)設(she)備時(shi)會(hui)遇(yu)到許多問題：無法完(wan)全清(qing)除積垢(gou)(gou)(gou)(gou)，例(li)如水垢(gou)(gou)(gou)(gou)，酸(suan)(suan)腐蝕(shi)會(hui)導(dao)致(zhi)(zhi)設(she)備腐蝕(shi)。殘留(liu)酸(suan)(suan)可能(neng)會(hui)導(dao)致(zhi)(zhi)材料發(fa)生二次腐蝕(shi)或水垢(gou)(gou)(gou)(gou)腐蝕(shi)，從而(er)(er)可能(neng)導(dao)致(zhi)(zhi)設(she)備更換。另外(wai)，清(qing)潔(jie)廢液是有毒...

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，?
