在(zai)(zai)使用(yong)水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)時(shi)(shi),氣(qi)(qi)蝕是(shi)一(yi)個普遍的問(wen)題。水(shui)(shui)環(huan)(huan)(huan)(huan)泵(beng)(beng)(beng)(beng)的真(zhen)(zhen)空(kong)度(du)不能滿足要(yao)求,影(ying)響(xiang)(xiang)水(shui)(shui)環(huan)(huan)(huan)(huan)泵(beng)(beng)(beng)(beng)的正(zheng)常使用(yong)。因(yin)此(ci),如(ru)何(he)避免水(shui)(shui)環(huan)(huan)(huan)(huan)泵(beng)(beng)(beng)(beng)的氣(qi)(qi)蝕已(yi)成為(wei)許多(duo)(duo)用(yong)戶面臨的主要(yao)問(wen)題。水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)制造(zao)商(shang)向(xiang)我(wo)們(men)介紹了以(yi)下內容。  在(zai)(zai)水(shui)(shui)環(huan)(huan)(huan)(huan)式真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)運行期間,真(zhen)(zhen)空(kong)度(du)越高,沸點越低。當液體(ti)沸騰(teng)時(shi)(shi),會(hui)(hui)(hui)形成許多(duo)(duo)氣(qi)(qi)泡。這些(xie)小氣(qi)(qi)泡很容易破裂,在(zai)(zai)研(yan)磨過程(cheng)中葉輪會(hui)(hui)(hui)受到嚴重(zhong)影(ying)響(xiang)(xiang)。在(zai)(zai)白(bai)天和黑夜里,葉輪會(hui)(hui)(hui)破裂。如(ru)果(guo)嚴重(zhong)損壞(huai),則由于無法修復,可(ke)能會(hui)(hui)(hui)被迫更換(huan)。如(ru)果(guo)工作液流(liu)量過大,它們(men)還會(hui)(hui)(hui)產(chan)生尖(jian)銳的噪音,因(yin)此(ci)有(you)(you)必要(yao)降低流(liu)量。  處理措(cuo)施(shi):針對這種現象(xiang),可(ke)將葉輪設(she)計(ji)為(wei)銅(tong)葉輪,不銹鋼葉輪等(deng)材料。水(shui)(shui)環(huan)(huan)(huan)(huan)泵(beng)(beng)(beng)(beng)的前面有(you)(you)一(yi)個氣(qi)(qi)蝕閥(fa)。當空(kong)化噪音太(tai)大時(shi)(shi),稍微轉動空(kong)化閥(fa)可(ke)以(yi)降低噪音。但是(shi),由于真(zhen)(zhen)空(kong)度(du)會(hui)(hui)(hui)大大降低,因(yin)此(ci)要(yao)求高真(zhen)(zhen)空(kong)度(du)的工藝不適用(yong)。  在(zai)(zai)使用(yong)水(shui)(shui)環(huan)(huan)(huan)(huan)式真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)的過程(cheng)中,如(ru)果(guo)出現氣(qi)(qi)蝕現象(xiang),應立即將其停(ting)止,并應采取(qu)有(you)(you)效措(cuo)施(shi)停(ting)止該(gai)過程(cheng)。另外,在(zai)(zai)實踐中,遵循(xun)正(zheng)確的步驟(zou)可(ke)以(yi)有(you)(you)效地防止出現氣(qi)(qi)穴問(wen)題。

新的醫用負壓真空系(xi)統解決應用方案

由于(yu)醫院(yuan)環境的(de)特殊(shu)性,所以對(dui)醫用真空系統的(de)滅(mie)菌(jun)能力、自動控制、設備穩定性等都有嚴格的(de)要求,尤其是醫用真空系統的(de)滅(mie)菌(jun)功能。

醫院真空系統的抽氣介質中存在細菌、病毒等各種微生物,因此真空系統需要合理配置滅菌單元,最大限度的殺滅有害微生物,以免對環境產生危害。


目前常(chang)見(jian)的(de)醫用負壓(ya)系統(tong)由集污(wu)罐(guan)、氣液分離器、真空(kong)緩沖罐(guan)、細菌過濾器、真空(kong)泵組成,如(ru)圖所示(shi):


醫用負壓真空系統結構圖


常見的醫用負壓(ya)系統使(shi)用的現狀:


一、前(qian)段(duan)只配有一道細菌過濾器(qi)

醫用真(zhen)空系統前(qian)段只配有一道細菌過濾器(qi),僅考核0.2~0.5μm以上粒(li)徑的去除比例,對(dui)低于0.2~0.5μm粒(li)徑的沒(mei)有參考意義,對(dui)細菌有一定過濾效果,但(dan)難以過濾病(bing)毒。


二、缺(que)少對病毒及(ji)細菌滅(mie)活的高(gao)溫滅(mie)菌措(cuo)施

這種無高溫滅菌措施(shi)的醫療負(fu)壓(ya)系統(tong),重點在“防”而(er)非“滅”,很難從(cong)根本性解決二次污染問題。


新的醫用負壓真空系統解決應用方案:

針對這些問題,恒才提出“滅(mie)活(huo)為主(zhu),滅(mie)而非防”的思路,采用具(ju)有(you)廣譜滅(mie)火(huo)特性的化學滅(mie)活(huo)為主(zhu),高溫滅(mie)活(huo)為輔的系統(tong)設計,達到防腐(fu)滅(mie)菌的目的,可保證排氣(qi)的安全。

高溫滅活利用變頻爪泵(爪型干式真空泵:無油無水,干式運行),在運行過程中產生的高溫進行輔助滅活,可從根本上解決排氣的二次污染。
