單級水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵通常用于(yu)造(zao)(zao)(zao)(zao)紙(zhi)(zhi)廠，以提供全方(fang)位的真(zhen)(zhen)空(kong)(kong)(kong)能(neng)(neng)力。現代造(zao)(zao)(zao)(zao)紙(zhi)(zhi)機使(shi)用真(zhen)(zhen)空(kong)(kong)(kong)輔助造(zao)(zao)(zao)(zao)紙(zhi)(zhi)脫水(shui)(shui)，因此真(zhen)(zhen)空(kong)(kong)(kong)系統(tong)是(shi)(shi)造(zao)(zao)(zao)(zao)紙(zhi)(zhi)機的重(zhong)要組成部(bu)分。 隨著酸性造(zao)(zao)(zao)(zao)紙(zhi)(zhi)向(xiang)中性造(zao)(zao)(zao)(zao)紙(zhi)(zhi)的發展，造(zao)(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵的結(jie)(jie)垢(gou)成為每個造(zao)(zao)(zao)(zao)紙(zhi)(zhi)企業經常遇(yu)到的問(wen)題(ti)(ti)。無論是(shi)(shi)在(zai)(zai)南部(bu)還是(shi)(shi)北部(bu)形(xing)成，它都不(bu)(bu)是(shi)(shi)立即(ji)生成的，而是(shi)(shi)結(jie)(jie)的過程。氧化皮(pi)的生產，其對(dui)造(zao)(zao)(zao)(zao)紙(zhi)(zhi)機的影響正在(zai)(zai)逐漸(jian)顯現，因此，從(cong)一(yi)開始就不(bu)(bu)能(neng)(neng)掉以輕心，要始終(zhong)如(ru)一(yi)地防止氧化皮(pi)的控(kong)制，這將(jiang)具(ju)有長期的利益。 (1)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵結(jie)(jie)垢(gou)的原(yuan)因： 1.水(shui)(shui)質影響：高(gao)(gao)ph值和高(gao)(gao)硬度(du)(du)。 2.造(zao)(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)的增(zeng)白程度(du)(du)增(zeng)加(jia)(jia)，不(bu)(bu)溶(rong)物(wu)(wu)含量(liang)(liang)高(gao)(gao)，并且垢(gou)離子積(ji)累。 3.大(da)量(liang)(liang)填充物(wu)(wu)。 4.溫度(du)(du)：水(shui)(shui)溫升高(gao)(gao)，冷卻(que)系統(tong)使(shi)用不(bu)(bu)充分。 5水(shui)(shui)循環(huan)系統(tong)沒有定期的清潔(jie)和維護，這將(jiang)增(zeng)加(jia)(jia)造(zao)(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵結(jie)(jie)垢(gou)的可(ke)能(neng)(neng)性。 (2)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵對(dui)造(zao)(zao)(zao)(zao)紙(zhi)(zhi)的不(bu)(bu)利影響 1.嚴重(zhong)降低真(zhen)(zhen)空(kong)(kong)(kong)度(du)(du)和抽氣量(liang)(liang)。 2.電(dian)(dian)動機電(dian)(dian)流上升，導致(zhi)(zhi)功耗增(zeng)加(jia)(jia)。 3.經常導致(zhi)(zhi)真(zhen)(zhen)空(kong)(kong)(kong)泵卡住，難以啟動，造(zao)(zao)(zao)(zao)紙(zhi)(zhi)機停止并且真(zhen)(zhen)空(kong)(kong)(kong)泵不(bu)(bu)敢停止。 4.頻繁的酸洗或手(shou)動拆卸不(bu)(bu)僅(jin)會損(sun)壞設(she)(she)(she)備(bei)，還會破壞設(she)(she)(she)備(bei)的精度(du)(du)，導致(zhi)(zhi)形(xing)成真(zhen)(zhen)空(kong)(kong)(kong)或降低真(zhen)(zhen)空(kong)(kong)(kong)度(du)(du)。 (3)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)泵解(jie)決(jue)方(fang)案 長期以來，傳統(tong)的清潔(jie)方(fang)法(例如(ru)機械方(fang)法(刮擦，刷牙)，高(gao)(gao)壓水(shui)(shui)，化學清潔(jie)(酸洗)等)在(zai)(zai)清潔(jie)設(she)(she)(she)備(bei)時會遇(yu)到許多問(wen)題(ti)(ti)：無法完全清除(chu)積(ji)垢(gou)，例如(ru)水(shui)(shui)垢(gou)，酸腐蝕會導致(zhi)(zhi)設(she)(she)(she)備(bei)腐蝕。殘留酸可(ke)能(neng)(neng)會導致(zhi)(zhi)材料發生二次(ci)腐蝕或水(shui)(shui)垢(gou)腐蝕，從(cong)而可(ke)能(neng)(neng)導致(zhi)(zhi)設(she)(she)(she)備(bei)更換。另外，清潔(jie)廢(fei)液是(shi)(shi)有毒...

離心泵(beng)(beng)有很多不(bu)同(tong)的(de)(de)類型，對于(yu)不(bu)同(tong)液(ye)體需要選(xuan)擇(ze)不(bu)同(tong)的(de)(de)離心泵(beng)(beng)，液(ye)體粘度不(bu)大(da)(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)(jiao)大(da)(da)(da)、揚程(cheng)不(bu)高時(shi)，宜(yi)選(xuan)用(yong)(yong)往復泵(beng)(beng)；液(ye)體粘度較(jiao)(jiao)(jiao)大(da)(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)(jiao)小、揚程(cheng)不(bu)高或含(han)有氣(qi)泡時(shi)，可選(xuan)用(yong)(yong)旋渦泵(beng)(beng)；液(ye)體粘度較(jiao)(jiao)(jiao)大(da)(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)(jiao)小、揚程(cheng)較(jiao)(jiao)(jiao)高時(shi)，宜(yi)選(xuan)用(yong)(yong)轉子泵(beng)(beng)。 理解類型的(de)(de)選(xuan)擇(ze)是(shi)(shi)最基本(ben)的(de)(de)，只有正確(que)選(xuan)擇(ze)才能使得正常運(yun)轉，但是(shi)(shi)我們在使用(yong)(yong)中(zhong)經常會遇到(dao)突(tu)然泄(xie)漏(lou)的(de)(de)問題，這又是(shi)(shi)哪(na)些原因造成(cheng)的(de)(de)呢？下面(mian)就來分(fen)析一下。 1、抽空、氣(qi)蝕(shi)或較(jiao)(jiao)(jiao)長時(shi)間憋(bie)壓，導致密封破(po)壞； 2、對泵(beng)(beng)實(shi)際輸出量(liang)偏(pian)小，大(da)(da)(da)量(liang)介(jie)質(zhi)(zhi)泵(beng)(beng)內循(xun)環(huan)，熱量(liang)積聚，引起介(jie)質(zhi)(zhi)氣(qi)化(hua)，導致密封失(shi)效(xiao)； 3、回流(liu)(liu)(liu)量(liang)偏(pian)大(da)(da)(da)，導致吸(xi)人管(guan)側容(rong)器(塔、釜(fu)、罐、池)底部沉(chen)渣泛(fan)起，損(sun)壞密封； 4、對較(jiao)(jiao)(jiao)長時(shi)間停(ting)運(yun)，重新起動時(shi)沒有手動盤車，摩擦副因粘連(lian)而扯壞密封面(mian)； 5、介(jie)質(zhi)(zhi)中(zhong)腐蝕(shi)性、聚合性、結(jie)膠性物質(zhi)(zhi)增(zeng)多； 6、環(huan)境溫度急劇變化(hua)； 7、工況頻繁變化(hua)或調整； 8、突(tu)然停(ting)電或故(gu)障(zhang)停(ting)機等。 當遇到(dao)突(tu)然泄(xie)漏(lou)的(de)(de)問題，我們一定要正確(que)分(fen)析，以(yi)采取對的(de)(de)措施，以(yi)免造成(cheng)不(bu)要的(de)(de)損(sun)失(shi)。

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?
