單級水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵通常(chang)用(yong)于造(zao)(zao)(zao)紙(zhi)(zhi)廠，以提供全方(fang)(fang)位的(de)(de)(de)(de)真(zhen)空(kong)(kong)(kong)能力。現代造(zao)(zao)(zao)紙(zhi)(zhi)機(ji)使(shi)用(yong)真(zhen)空(kong)(kong)(kong)輔(fu)助造(zao)(zao)(zao)紙(zhi)(zhi)脫水(shui)(shui)，因(yin)此真(zhen)空(kong)(kong)(kong)系(xi)統(tong)是造(zao)(zao)(zao)紙(zhi)(zhi)機(ji)的(de)(de)(de)(de)重要組成(cheng)(cheng)部(bu)分。 隨著(zhu)酸(suan)(suan)性造(zao)(zao)(zao)紙(zhi)(zhi)向中性造(zao)(zao)(zao)紙(zhi)(zhi)的(de)(de)(de)(de)發(fa)展(zhan)，造(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵的(de)(de)(de)(de)結(jie)垢成(cheng)(cheng)為每個(ge)造(zao)(zao)(zao)紙(zhi)(zhi)企業經(jing)常(chang)遇到的(de)(de)(de)(de)問題。無(wu)論是在南部(bu)還是北(bei)部(bu)形成(cheng)(cheng)，它都不(bu)(bu)(bu)是立(li)即生成(cheng)(cheng)的(de)(de)(de)(de)，而是結(jie)的(de)(de)(de)(de)過(guo)程。氧化皮的(de)(de)(de)(de)生產，其對(dui)造(zao)(zao)(zao)紙(zhi)(zhi)機(ji)的(de)(de)(de)(de)影響(xiang)正在逐漸顯(xian)現，因(yin)此，從一(yi)開始(shi)(shi)就不(bu)(bu)(bu)能掉以輕心，要始(shi)(shi)終如一(yi)地防止(zhi)氧化皮的(de)(de)(de)(de)控制，這將具有長期的(de)(de)(de)(de)利益(yi)。 (1)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵結(jie)垢的(de)(de)(de)(de)原因(yin)： 1.水(shui)(shui)質影響(xiang)：高ph值和(he)高硬度(du)(du)。 2.造(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)的(de)(de)(de)(de)增白程度(du)(du)增加，不(bu)(bu)(bu)溶(rong)物(wu)含(han)量(liang)高，并且垢離子積(ji)累(lei)。 3.大(da)量(liang)填充物(wu)。 4.溫度(du)(du)：水(shui)(shui)溫升(sheng)高，冷卻系(xi)統(tong)使(shi)用(yong)不(bu)(bu)(bu)充分。 5水(shui)(shui)循環(huan)(huan)系(xi)統(tong)沒有定期的(de)(de)(de)(de)清(qing)(qing)(qing)潔和(he)維護，這將增加造(zao)(zao)(zao)紙(zhi)(zhi)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵結(jie)垢的(de)(de)(de)(de)可能性。 (2)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵對(dui)造(zao)(zao)(zao)紙(zhi)(zhi)的(de)(de)(de)(de)不(bu)(bu)(bu)利影響(xiang) 1.嚴重降(jiang)低真(zhen)空(kong)(kong)(kong)度(du)(du)和(he)抽氣(qi)量(liang)。 2.電動機(ji)電流上升(sheng)，導(dao)(dao)致(zhi)功(gong)耗(hao)增加。 3.經(jing)常(chang)導(dao)(dao)致(zhi)真(zhen)空(kong)(kong)(kong)泵卡住，難以啟動，造(zao)(zao)(zao)紙(zhi)(zhi)機(ji)停止(zhi)并且真(zhen)空(kong)(kong)(kong)泵不(bu)(bu)(bu)敢停止(zhi)。 4.頻繁的(de)(de)(de)(de)酸(suan)(suan)洗或手動拆卸不(bu)(bu)(bu)僅會(hui)(hui)損(sun)壞(huai)設備，還會(hui)(hui)破壞(huai)設備的(de)(de)(de)(de)精度(du)(du)，導(dao)(dao)致(zhi)形成(cheng)(cheng)真(zhen)空(kong)(kong)(kong)或降(jiang)低真(zhen)空(kong)(kong)(kong)度(du)(du)。 (3)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵解決方(fang)(fang)案(an) 長期以來(lai)，傳統(tong)的(de)(de)(de)(de)清(qing)(qing)(qing)潔方(fang)(fang)法(例(li)如機(ji)械(xie)方(fang)(fang)法(刮擦，刷牙)，高壓(ya)水(shui)(shui)，化學清(qing)(qing)(qing)潔(酸(suan)(suan)洗)等)在清(qing)(qing)(qing)潔設備時會(hui)(hui)遇到許(xu)多問題：無(wu)法完全清(qing)(qing)(qing)除積(ji)垢，例(li)如水(shui)(shui)垢，酸(suan)(suan)腐蝕(shi)(shi)會(hui)(hui)導(dao)(dao)致(zhi)設備腐蝕(shi)(shi)。殘留酸(suan)(suan)可能會(hui)(hui)導(dao)(dao)致(zhi)材料發(fa)生二(er)次腐蝕(shi)(shi)或水(shui)(shui)垢腐蝕(shi)(shi)，從而可能導(dao)(dao)致(zhi)設備更換。另外，清(qing)(qing)(qing)潔廢(fei)液是有毒...

眾所(suo)周(zhou)知(zhi)，對于(yu)各種真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)性(xing)能(neng)，都有(you)規定的(de)(de)(de)(de)(de)測試(shi)方法來(lai)測試(shi)該性(xing)能(neng)的(de)(de)(de)(de)(de)性(xing)能(neng)，主要(yao)性(xing)能(neng)是極(ji)限(xian)壓(ya)力(li)(li)，流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)和抽(chou)(chou)速(su)(su)。這(zhe)次，小編打(da)算(suan)討論螺(luo)桿真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)，例如如何控(kong)(kong)制其流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)，流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)不(bu)(bu)足的(de)(de)(de)(de)(de)原因以及如何消除此(ci)問(wen)題。相信許多(duo)用(yong)戶(hu)對這(zhe)些問(wen)題感到困惑，不(bu)(bu)用(yong)擔心，請跟隨(sui)螺(luo)桿真空(kong)(kong)泵(beng)(beng)廠家進行了(le)解。 首先，讓我們(men)簡單介紹一下真空(kong)(kong)泵(beng)(beng)主要(yao)性(xing)能(neng)的(de)(de)(de)(de)(de)概念(nian)。 1.極(ji)限(xian)壓(ya)力(li)(li)。真空(kong)(kong)泵(beng)(beng)與檢測容器(qi)相連，放置待測氣(qi)(qi)體(ti)(ti)(ti)后，連續長時間(jian)(jian)抽(chou)(chou)氣(qi)(qi)。當容器(qi)的(de)(de)(de)(de)(de)氣(qi)(qi)壓(ya)不(bu)(bu)再(zai)降低并(bing)且壓(ya)力(li)(li)保(bao)持在(zai)一定值時，次級(ji)壓(ya)力(li)(li)就是泵(beng)(beng)的(de)(de)(de)(de)(de)極(ji)限(xian)壓(ya)力(li)(li)。 2.流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)。在(zai)真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)吸入(ru)口，每(mei)單位時間(jian)(jian)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)。在(zai)真空(kong)(kong)技(ji)術中，流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)單位以壓(ya)力(li)(li)*體(ti)(ti)(ti)積/時間(jian)(jian)表示，即Pa.m3/s或(huo)Pa.m3/h。通(tong)常，泵(beng)(beng)會(hui)給出流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)與入(ru)口壓(ya)力(li)(li)的(de)(de)(de)(de)(de)關系(xi)圖。 3.抽(chou)(chou)速(su)(su)。在(zai)真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)吸入(ru)口，每(mei)單位時間(jian)(jian)流(liu)(liu)動的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)(su)率(lv)。即，通(tong)過將流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)QA(Pa.m3/s)除以測試(shi)罩中的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)A的(de)(de)(de)(de)(de)分(fen)壓(ya)pA而獲得(de)氣(qi)(qi)體(ti)(ti)(ti)A的(de)(de)(de)(de)(de)泵(beng)(beng)送速(su)(su)度(du)sA(m3/s)。典型(xing)的(de)(de)(de)(de)(de)真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)(su)率(lv)與氣(qi)(qi)體(ti)(ti)(ti)類型(xing)有(you)關。給定的(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)(su)率(lv)表示某種氣(qi)(qi)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)(su)率(lv)。如果沒有(you)特殊指(zhi)示，則使用(yong)多(duo)指(zhi)抽(chou)(chou)吸。 正確控(kong)(kong)制螺(luo)桿真空(kong)(kong)泵(beng)(beng)流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)不(bu)(bu)僅(jin)可以為設備(bei)提供良好(hao)的(de)(de)(de)(de)(de)保(bao)護，還可以提高使用(yong)率(lv)。那么(me)，該怎么(me)做(zuo)呢? 1，速(su)(su)度(du)控(kong)(kong)制 葉輪速(su)(su)度(du)的(de)(de)(de)(de)(de)變化會(hui)改變螺(luo)桿真空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)(liang)(liang)(liang)(liang)(liang)曲線(xian)，并(bing)且曲線(xian)的(de)(de)(de)(de)(de)特性(xing)不(bu)(bu)會(hui)改變。隨(sui)著(zhu)速(su)(su)度(du)降低，曲線(xian)變平，揚程和流(liu)(liu)速(su)(su)降低。 2，旁通(tong)閥調整 使用(yong)與泵(beng)(beng)并(bing)聯的(de)(de)(de)(de)(de)中間(jian)(jian)閥。實(shi)際效(xiao)果就...

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?
