水環(huan)真(zhen)空(kong)(kong)泵(beng)是(shi)在cnc工(gong)業(ye)中使(shi)用(yong)的(de)(de)真(zhen)空(kong)(kong)泵(beng)。它(ta)的(de)(de)體積很小(xiao),但效果(guo)(guo)(guo)很好(hao)。如(ru)今,許多人質疑(yi)設備軸封(feng)(feng)(feng)(feng)(feng)是(shi)否(fou)未正(zheng)確滴(di)落(luo)(luo)(luo)。那么,這是(shi)異常(chang)的(de)(de)嗎?讓我在下面(mian)回答。  1、 水環(huan)真(zhen)空(kong)(kong)泵(beng)的(de)(de)軸封(feng)(feng)(feng)(feng)(feng)可能沒(mei)有(you)滴(di)落(luo)(luo)(luo),但如(ru)果(guo)(guo)(guo)泵(beng)是(shi)機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng),則(ze)不(bu)可能滴(di)落(luo)(luo)(luo)。  2、如(ru)果(guo)(guo)(guo)需要滴(di)水,滴(di)水頻率(lv)應為(wei)每分鐘約6-8滴(di)。  3、滴(di)灌劑(ji)有(you)兩個作(zuo)用(yong):冷卻和(he)潤滑。  4、填(tian)料(liao)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)也(ye)稱(cheng)為(wei)壓(ya)(ya)緊填(tian)料(liao)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng),通常(chang)稱(cheng)為(wei)填(tian)料(liao)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)。  5、軸封(feng)(feng)(feng)(feng)(feng)有(you)兩種(zhong)主要形(xing)式:傳統(tong)上常(chang)見的(de)(de)填(tian)料(liao)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)和(he)機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)。  6、當設備運行(xing)時,調節填(tian)料(liao)壓(ya)(ya)蓋以調節填(tian)料(liao)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)的(de)(de)泄漏。  7、機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)  ①是(shi)指由至少一對垂直于旋轉(zhuan)軸的(de)(de)端(duan)面(mian)組成的(de)(de)防止流(liu)體泄漏的(de)(de)裝(zhuang)置(zhi),在流(liu)體壓(ya)(ya)力和(he)補償機(ji)(ji)構的(de)(de)彈力的(de)(de)作(zuo)用(yong)下,以及與之配合(he)使(shi)用(yong)時,該(gai)端(duan)面(mian)保持接觸并(bing)滑動。輔助密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)。  ②彈性加載機(ji)(ji)構和(he)輔助密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)金屬(shu)波紋管的(de)(de)機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)。我們(men)稱(cheng)它(ta)們(men)為(wei)金屬(shu)波紋管密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)。  ③密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)件(jian)泄漏少:基本上沒(mei)有(you)滴(di)落(luo)(luo)(luo),壽命長的(de)(de)優點,因此(ci),世界上的(de)(de)機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)是(shi)這些裝(zhuang)置(zhi)的(de)(de)主軸密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)方法。機(ji)(ji)械(xie)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)也(ye)稱(cheng)為(wei)端(duan)面(mian)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)。  水環(huan)真(zhen)空(kong)(kong)泵(beng)具有(you)良好(hao)的(de)(de)安全(quan)性,已廣泛用(yong)于cnc行(xing)業(ye)。因此(ci),其軸封(feng)(feng)(feng)(feng)(feng)不(bu)會(hui)正(zheng)常(chang)滴(di)落(luo)(luo)(luo)。如(ru)果(guo)(guo)(guo)滴(di)落(luo)(luo)(luo)了(le),則(ze)不(bu)能稱(cheng)為(wei)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng),因此(ci)您(nin)不(bu)必擔心此(ci)問題(ti)。

水環(huan)式真空(kong)泵(beng)(beng)是(shi)目前工(gong)(gong)(gong)業上常見的(de)(de)(de)(de)(de)真空(kong)泵(beng)(beng)設備(bei)。許多人在(zai)使(shi)用(yong)它(ta)時(shi)(shi)會絆倒,從而延誤工(gong)(gong)(gong)作(zuo)過程(cheng)。為了避免這(zhe)(zhe)(zhe)種情(qing)況再次(ci)(ci)發生,我(wo)們(men)需要(yao)知道(dao)原因(yin)(yin)(yin),所(suo)以(yi)讓我(wo)們(men)來分析跳(tiao)閘的(de)(de)(de)(de)(de)原因(yin)(yin)(yin)。  一(yi)(yi)(yi)、工(gong)(gong)(gong)作(zuo)的(de)(de)(de)(de)(de)過程(cheng)因(yin)(yin)(yin)素(su)  1.如果(guo)設備(bei)停(ting)止工(gong)(gong)(gong)作(zuo),當水環(huan)式真空(kong)泵(beng)(beng)再次(ci)(ci)啟動時(shi)(shi),大(da)量的(de)(de)(de)(de)(de)水將被吸入底部的(de)(de)(de)(de)(de)泵(beng)(beng)中,這(zhe)(zhe)(zhe)將導致過載(zai)和(he)過流跳(tiao)閘。  2.如果(guo)在(zai)從箱(xiang)(xiang)體(ti)(ti)底部抽吸的(de)(de)(de)(de)(de)情(qing)況下(xia),每次(ci)(ci)使(shi)用(yong)后由(you)(you)于箱(xiang)(xiang)體(ti)(ti)內(nei)形成負壓(ya)而使(shi)吸管(guan)和(he)單元光滑,箱(xiang)(xiang)體(ti)(ti)內(nei)的(de)(de)(de)(de)(de)水將在(zai)負壓(ya)的(de)(de)(de)(de)(de)作(zuo)用(yong)下(xia)被吸入箱(xiang)(xiang)體(ti)(ti)內(nei)。  二,兩個合并因(yin)(yin)(yin)素(su)  1.兩臺(tai)機器被合并成一(yi)(yi)(yi)條管(guan)道(dao),但是(shi)他們(men)忘記(ji)在(zai)兩臺(tai)泵(beng)(beng)之間安裝(zhuang)閥(fa)門。入口(kou)處只安裝(zhuang)了一(yi)(yi)(yi)個單向閥(fa)。這(zhe)(zhe)(zhe)個單向閥(fa)不能完全密封,因(yin)(yin)(yin)此導致跳(tiao)閘。  2.由(you)(you)于采用(yong)一(yi)(yi)(yi)用(yong)一(yi)(yi)(yi)備(bei)的(de)(de)(de)(de)(de)工(gong)(gong)(gong)作(zuo)方式,一(yi)(yi)(yi)臺(tai)泵(beng)(beng)工(gong)(gong)(gong)作(zuo)時(shi)(shi)會出(chu)現(xian)從另一(yi)(yi)(yi)臺(tai)泵(beng)(beng)抽水的(de)(de)(de)(de)(de)現(xian)象,甚至(zhi)會出(chu)現(xian)從排氣(qi)管(guan)抽出(chu)循環(huan)水和(he)大(da)氣(qi)的(de)(de)(de)(de)(de)現(xian)象,這(zhe)(zhe)(zhe)也是(shi)跳(tiao)閘的(de)(de)(de)(de)(de)原因(yin)(yin)(yin)。  如果(guo)不小心(xin)維護水環(huan)式真空(kong)泵(beng)(beng),會有更多不知情(qing)的(de)(de)(de)(de)(de)問題。我(wo)們(men)應該(gai)對它(ta)跳(tiao)閘和(he)停(ting)止工(gong)(gong)(gong)作(zuo)的(de)(de)(de)(de)(de)原因(yin)(yin)(yin)有一(yi)(yi)(yi)些常識。此外,平(ping)時(shi)(shi)使(shi)用(yong)時(shi)(shi)必須(xu)注意,盡量減(jian)少(shao)使(shi)用(yong)損失,提高工(gong)(gong)(gong)作(zuo)效率。

水環真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)是造紙行業最(zui)常(chang)用的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)之一。目(mu)前,大部分已完(wan)成(cheng)的(de)(de)(de)(de)(de)(de)造紙機項(xiang)目(mu)仍采用水環真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)作為(wei)真(zhen)(zhen)空(kong)系(xi)統(tong)(tong)的(de)(de)(de)(de)(de)(de)標準。  優勢(shi):  本發(fa)明結(jie)構簡單,制(zhi)(zhi)造精度(du)要(yao)(yao)求低,易于加(jia)(jia)工(gong)。  結(jie)構緊湊(cou),泵(beng)(beng)(beng)轉(zhuan)速(su)高(gao)。一般情況下,它可以(yi)(yi)直接與電機連接,無(wu)需減速(su)器(qi)。因此(ci),利用小(xiao)的(de)(de)(de)(de)(de)(de)結(jie)構尺寸,可以(yi)(yi)獲得大的(de)(de)(de)(de)(de)(de)排氣(qi)容積,并(bing)且占據的(de)(de)(de)(de)(de)(de)面積也(ye)小(xiao)。  壓(ya)縮氣(qi)體(ti)基本上(shang)是等溫(wen)(wen)的(de)(de)(de)(de)(de)(de),即壓(ya)縮氣(qi)體(ti)的(de)(de)(de)(de)(de)(de)工(gong)藝溫(wen)(wen)度(du)變化(hua)很小(xiao)。  由于泵(beng)(beng)(beng)腔內沒有金屬摩擦(ca)表(biao)面,因此(ci)泵(beng)(beng)(beng)內不(bu)需要(yao)(yao)潤滑(hua),磨損非常(chang)小(xiao)。旋轉(zhuan)部件(jian)(jian)和固定(ding)部件(jian)(jian)之間的(de)(de)(de)(de)(de)(de)密封可以(yi)(yi)通過(guo)水封直接完(wan)成(cheng)。  抽(chou)吸(xi)均勻(yun),運(yun)行穩定(ding)可靠(kao),操作簡單,維護方便。  缺點:  效率低,通常(chang)約為(wei)30%,優選高(gao)達50%。  真(zhen)(zhen)空(kong)度(du)低,這(zhe)不(bu)僅受到結(jie)構的(de)(de)(de)(de)(de)(de)限(xian)(xian)制(zhi)(zhi),更重(zhong)(zhong)要(yao)(yao)的(de)(de)(de)(de)(de)(de)是受到工(gong)作流體(ti)飽和蒸汽壓(ya)的(de)(de)(de)(de)(de)(de)限(xian)(xian)制(zhi)(zhi)。以(yi)(yi)水為(wei)工(gong)作流體(ti),極限(xian)(xian)壓(ya)力(li)只能達到2000 ~ 4000帕。  水環真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)節能;  1.溫(wen)(wen)度(du)越高(gao),氣(qi)體(ti)的(de)(de)(de)(de)(de)(de)體(ti)積越大。當真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)達到相同(tong)(tong)的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)度(du)時,其吸(xi)力(li)流量(liang)也(ye)將增加(jia)(jia),這(zhe)將導致負載(zai)和能量(liang)消(xiao)耗(hao)的(de)(de)(de)(de)(de)(de)增加(jia)(jia)。因此(ci),控(kong)(kong)制(zhi)(zhi)循環白(bai)水的(de)(de)(de)(de)(de)(de)溫(wen)(wen)度(du)非常(chang)重(zhong)(zhong)要(yao)(yao),尤其是在夏季(ji),這(zhe)就要(yao)(yao)求冷(leng)卻系(xi)統(tong)(tong)保持良好的(de)(de)(de)(de)(de)(de)冷(leng)卻效果。一般認為(wei)循環白(bai)水最(zui)好不(bu)要(yao)(yao)超過(guo)35℃。如(ru)果夏季(ji)溫(wen)(wen)度(du)過(guo)高(gao),冷(leng)卻水流量(liang)可適(shi)當增加(jia)(jia),但同(tong)(tong)時應(ying)注意(yi),冷(leng)卻水流量(liang)過(guo)多(duo)也(ye)會導致能耗(hao)增加(jia)(jia),因此(ci)冷(leng)卻水流量(liang)在冬季(ji)應(ying)適(shi)當減少。  2.如(ru)果真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)容量(liang)明顯超過(guo)真(zhen)(zhen)空(kong)系(xi)統(tong)(tong)的(de)(de)(de)(de)(de)(de)需求,將會有過(guo)量(liang)的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong),并(bing)且泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)有效泵(beng)(beng)(beng)送速(su)率將被浪費。采用PID控(kong)(kong)制(zhi)(zhi)來調(diao)節變頻器(qi)...
