單級水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)通常用(yong)(yong)于造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)廠,以(yi)提供(gong)全方(fang)位的(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)能(neng)力(li)。現代(dai)造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)機使用(yong)(yong)真(zhen)(zhen)空(kong)(kong)輔助造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)脫水(shui),因(yin)此真(zhen)(zhen)空(kong)(kong)系統(tong)是(shi)造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)機的(de)(de)(de)(de)重要組成部分。 隨著酸性造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)向中性造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)發(fa)展,造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)結垢成為(wei)每個造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)企業經(jing)常遇到的(de)(de)(de)(de)問題(ti)。無論(lun)是(shi)在南部還是(shi)北部形成,它都不是(shi)立即生成的(de)(de)(de)(de),而是(shi)結的(de)(de)(de)(de)過程(cheng)。氧(yang)化(hua)皮(pi)的(de)(de)(de)(de)生產(chan),其對(dui)造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)機的(de)(de)(de)(de)影響(xiang)正在逐漸(jian)顯現,因(yin)此,從一開始就不能(neng)掉以(yi)輕心,要始終如(ru)一地(di)防(fang)止(zhi)氧(yang)化(hua)皮(pi)的(de)(de)(de)(de)控制(zhi),這將具有長(chang)期(qi)(qi)的(de)(de)(de)(de)利(li)益。 (1)水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)結垢的(de)(de)(de)(de)原因(yin): 1.水(shui)質影響(xiang):高(gao)(gao)ph值和高(gao)(gao)硬(ying)度(du)(du)。 2.造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)水(shui)的(de)(de)(de)(de)增白程(cheng)度(du)(du)增加(jia)(jia),不溶物含(han)量(liang)高(gao)(gao),并(bing)且(qie)垢離子積累。 3.大(da)量(liang)填充(chong)物。 4.溫度(du)(du):水(shui)溫升(sheng)高(gao)(gao),冷卻系統(tong)使用(yong)(yong)不充(chong)分。 5水(shui)循環系統(tong)沒有定期(qi)(qi)的(de)(de)(de)(de)清潔(jie)和維(wei)護,這將增加(jia)(jia)造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)結垢的(de)(de)(de)(de)可(ke)能(neng)性。 (2)水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)對(dui)造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)不利(li)影響(xiang) 1.嚴重降低真(zhen)(zhen)空(kong)(kong)度(du)(du)和抽氣(qi)量(liang)。 2.電動機電流上(shang)升(sheng),導致功耗增加(jia)(jia)。 3.經(jing)常導致真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)卡(ka)住,難以(yi)啟動,造(zao)(zao)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)機停(ting)止(zhi)并(bing)且(qie)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)不敢停(ting)止(zhi)。 4.頻(pin)繁的(de)(de)(de)(de)酸洗或手動拆卸(xie)不僅會(hui)損壞設(she)(she)備(bei)(bei),還會(hui)破壞設(she)(she)備(bei)(bei)的(de)(de)(de)(de)精度(du)(du),導致形成真(zhen)(zhen)空(kong)(kong)或降低真(zhen)(zhen)空(kong)(kong)度(du)(du)。 (3)水(shui)環真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)解決方(fang)案 長(chang)期(qi)(qi)以(yi)來,傳統(tong)的(de)(de)(de)(de)清潔(jie)方(fang)法(例如(ru)機械(xie)方(fang)法(刮擦,刷牙),高(gao)(gao)壓水(shui),化(hua)學清潔(jie)(酸洗)等)在清潔(jie)設(she)(she)備(bei)(bei)時會(hui)遇到許多問題(ti):無法完全清除積垢,例如(ru)水(shui)垢,酸腐(fu)蝕會(hui)導致設(she)(she)備(bei)(bei)腐(fu)蝕。殘留酸可(ke)能(neng)會(hui)導致材料發(fa)生二次腐(fu)蝕或水(shui)垢腐(fu)蝕,從而可(ke)能(neng)導致設(she)(she)備(bei)(bei)更換。另外,清潔(jie)廢液是(shi)有毒(du)...
