單級水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)通常(chang)用(yong)于造(zao)(zao)紙(zhi)(zhi)廠，以(yi)提供全方(fang)(fang)位的(de)(de)(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)能(neng)力。現代造(zao)(zao)紙(zhi)(zhi)機(ji)使(shi)用(yong)真(zhen)(zhen)(zhen)空(kong)(kong)輔助造(zao)(zao)紙(zhi)(zhi)脫水(shui)(shui)，因此真(zhen)(zhen)(zhen)空(kong)(kong)系統(tong)是(shi)(shi)造(zao)(zao)紙(zhi)(zhi)機(ji)的(de)(de)(de)(de)重要(yao)組(zu)成(cheng)部分。 隨(sui)著酸(suan)性造(zao)(zao)紙(zhi)(zhi)向中(zhong)性造(zao)(zao)紙(zhi)(zhi)的(de)(de)(de)(de)發(fa)展，造(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)結垢(gou)(gou)成(cheng)為每個造(zao)(zao)紙(zhi)(zhi)企(qi)業經(jing)常(chang)遇到的(de)(de)(de)(de)問題。無論是(shi)(shi)在(zai)(zai)南部還是(shi)(shi)北(bei)部形(xing)成(cheng)，它(ta)都不是(shi)(shi)立即生(sheng)成(cheng)的(de)(de)(de)(de)，而是(shi)(shi)結的(de)(de)(de)(de)過程。氧化(hua)皮的(de)(de)(de)(de)生(sheng)產，其對造(zao)(zao)紙(zhi)(zhi)機(ji)的(de)(de)(de)(de)影響(xiang)正在(zai)(zai)逐漸顯現，因此，從(cong)(cong)一(yi)開始(shi)就不能(neng)掉以(yi)輕心，要(yao)始(shi)終如(ru)(ru)一(yi)地防止氧化(hua)皮的(de)(de)(de)(de)控制，這將具有長期的(de)(de)(de)(de)利(li)(li)益。 (1)水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)結垢(gou)(gou)的(de)(de)(de)(de)原因： 1.水(shui)(shui)質影響(xiang)：高(gao)ph值和高(gao)硬度(du)。 2.造(zao)(zao)紙(zhi)(zhi)水(shui)(shui)的(de)(de)(de)(de)增白(bai)程度(du)增加，不溶物含量高(gao)，并且(qie)垢(gou)(gou)離子積累。 3.大量填充物。 4.溫(wen)度(du)：水(shui)(shui)溫(wen)升高(gao)，冷卻系統(tong)使(shi)用(yong)不充分。 5水(shui)(shui)循環(huan)(huan)系統(tong)沒有定期的(de)(de)(de)(de)清(qing)潔和維護，這將增加造(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)結垢(gou)(gou)的(de)(de)(de)(de)可(ke)能(neng)性。 (2)水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)對造(zao)(zao)紙(zhi)(zhi)的(de)(de)(de)(de)不利(li)(li)影響(xiang) 1.嚴重降(jiang)低(di)真(zhen)(zhen)(zhen)空(kong)(kong)度(du)和抽(chou)氣量。 2.電(dian)動(dong)(dong)機(ji)電(dian)流上升，導致功耗增加。 3.經(jing)常(chang)導致真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)卡住，難以(yi)啟動(dong)(dong)，造(zao)(zao)紙(zhi)(zhi)機(ji)停止并且(qie)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)不敢(gan)停止。 4.頻繁的(de)(de)(de)(de)酸(suan)洗或手動(dong)(dong)拆卸不僅會(hui)(hui)損壞設備(bei)，還會(hui)(hui)破壞設備(bei)的(de)(de)(de)(de)精度(du)，導致形(xing)成(cheng)真(zhen)(zhen)(zhen)空(kong)(kong)或降(jiang)低(di)真(zhen)(zhen)(zhen)空(kong)(kong)度(du)。 (3)水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)解決方(fang)(fang)案 長期以(yi)來(lai)，傳統(tong)的(de)(de)(de)(de)清(qing)潔方(fang)(fang)法(fa)(例如(ru)(ru)機(ji)械方(fang)(fang)法(fa)(刮(gua)擦，刷牙)，高(gao)壓水(shui)(shui)，化(hua)學(xue)清(qing)潔(酸(suan)洗)等(deng))在(zai)(zai)清(qing)潔設備(bei)時(shi)會(hui)(hui)遇到許多問題：無法(fa)完全清(qing)除積垢(gou)(gou)，例如(ru)(ru)水(shui)(shui)垢(gou)(gou)，酸(suan)腐蝕會(hui)(hui)導致設備(bei)腐蝕。殘留酸(suan)可(ke)能(neng)會(hui)(hui)導致材料(liao)發(fa)生(sheng)二(er)次(ci)腐蝕或水(shui)(shui)垢(gou)(gou)腐蝕，從(cong)(cong)而可(ke)能(neng)導致設備(bei)更換。另(ling)外(wai)，清(qing)潔廢(fei)液是(shi)(shi)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?
