真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)已經越來越常(chang)用(yong)，今天小編就(jiu)一(yi)些簡單故(gu)障(zhang)及其排(pai)(pai)除方(fang)法做以(yi)(yi)下(xia)介紹(shao)，希望對大(da)(da)家有所幫(bang)助！1.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)盤(pan)車(che)(che)不(bu)順利這(zhe)(zhe)(zhe)種(zhong)狀況(kuang)(kuang)產生的(de)(de)原因(yin)(yin)一(yi)般(ban)是久未(wei)使用(yong)造(zao)成盤(pan)端面處生銹或(huo)者(zhe)是因(yin)(yin)為(wei)水溫(wen)過(guo)高導致的(de)(de)泵(beng)(beng)(beng)腔結垢。排(pai)(pai)除方(fang)法是將泵(beng)(beng)(beng)腔內充入10%的(de)(de)草酸侵泡三十分鐘左右，然后(hou)松動(dong)泵(beng)(beng)(beng)蓋后(hou)再盤(pan)車(che)(che)，或(huo)者(zhe)是降(jiang)低(di)下(xia)工(gong)作液(ye)(ye)污垢系數。2.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)電(dian)(dian)(dian)(dian)機運轉不(bu)正常(chang)如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)電(dian)(dian)(dian)(dian)機缺(que)相(xiang)，就(jiu)檢查(cha)(cha)電(dian)(dian)(dian)(dian)源(yuan)接(jie)頭(tou)是否脫落(luo);如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)電(dian)(dian)(dian)(dian)壓不(bu)正常(chang)，就(jiu)檢查(cha)(cha)電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓;如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)交流(liu)接(jie)觸器損壞，就(jiu)換下(xia)交流(liu)接(jie)觸器。3.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)走動(dong)聲音(yin)異常(chang)一(yi)般(ban)是由(you)啟動(dong)時工(gong)作液(ye)(ye)充滿(man)泵(beng)(beng)(beng)腔造(zao)成的(de)(de)，這(zhe)(zhe)(zhe)時候打開(kai)排(pai)(pai)污口放出部分工(gong)作液(ye)(ye)是泵(beng)(beng)(beng)內工(gong)作液(ye)(ye)減(jian)少一(yi)部分就(jiu)可(ke)以(yi)(yi)了(le)。4.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)不(bu)能(neng)形(xing)成真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)這(zhe)(zhe)(zhe)種(zhong)情況(kuang)(kuang)由(you)兩種(zhong)原因(yin)(yin)造(zao)成，一(yi)是無工(gong)作液(ye)(ye)，這(zhe)(zhe)(zhe)時候檢查(cha)(cha)下(xia)工(gong)作液(ye)(ye)供應(ying)情況(kuang)(kuang)；二是轉向(xiang)錯誤(wu)，這(zhe)(zhe)(zhe)時候只要(yao)(yao)(yao)(yao)糾正轉向(xiang)就(jiu)可(ke)以(yi)(yi)了(le)。5.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)度(du)低(di)如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)泵(beng)(beng)(beng)選型(xing)較小以(yi)(yi)致抽(chou)氣(qi)(qi)速率低(di)，就(jiu)要(yao)(yao)(yao)(yao)更(geng)換下(xia)更(geng)大(da)(da)抽(chou)速的(de)(de)泵(beng)(beng)(beng);如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)工(gong)作液(ye)(ye)供應(ying)不(bu)足，就(jiu)要(yao)(yao)(yao)(yao)加大(da)(da)供應(ying);如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)工(gong)作液(ye)(ye)溫(wen)度(du)過(guo)高，就(jiu)要(yao)(yao)(yao)(yao)降(jiang)低(di)溫(wen)度(du);如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)系統漏(lou)氣(qi)(qi)，就(jiu)要(yao)(yao)(yao)(yao)檢查(cha)(cha)并(bing)(bing)堵(du)漏(lou);如(ru)(ru)(ru)(ru)果(guo)因(yin)(yin)為(wei)圓(yuan)盤(pan)或(huo)者(zhe)葉輪被腐蝕，就(jiu)要(yao)(yao)(yao)(yao)檢查(cha)(cha)并(bing)(bing)更(geng)換圓(yuan)輪或(huo)者(zhe)葉輪。6.水環式真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)電(dian)(dian)(dian)(dian)流(liu)偏大(da)(da)看下(xia)是不(bu)是由(you)于(yu)排(pai)(pai)水管向(xiang)上的(de)(de)管路過(guo)高引(yin)起，如(ru)(ru)(ru)(ru)果(guo)是就(jiu)降(jiang)低(di)排(pai)(pai)水管高度(du)就(jiu)可(ke)以(yi)(yi)了(le);如(ru)(ru)(ru)(ru)果(guo)是因(yin)(yin)為(wei)工(gong)作液(ye)(ye)供應(ying)量過(guo)大(da)(da)，就(jiu)要(yao)(yao)(yao)(yao)減(jian)少工(gong)作液(ye)(ye)供應(ying)就(jiu)可(ke)以(yi)(yi)了(le)。7.真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)機械(xie)密封泄漏(lou)一(yi)般(ban)是由(you)于(yu)未(wei)注入工(gong)作液(ye)(ye)及冷卻(que)液(ye)(ye)的(de)(de)情況(kuang)(kuang)下(xia)干運行泵(beng)(beng)(beng)引(yin)起的(de)(de)，這(zhe)(zhe)(zhe)時候就(jiu)需要(yao)(yao)(yao)(yao)更(geng)換機械(xie)密封，更(geng)改操作規程(cheng)

在傳統(tong)(tong)的(de)(de)單張(zhang)(zhang)紙(zhi)(zhi)(zhi)膠(jiao)印(yin)機(ji)(ji)(ji)中，紙(zhi)(zhi)(zhi)張(zhang)(zhang)處(chu)理過(guo)程中始終需(xu)要真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)和過(guo)壓(ya)(ya).在給(gei)(gei)紙(zhi)(zhi)(zhi)裝(zhuang)(zhuang)置中用(yong)于分(fen)離紙(zhi)(zhi)(zhi)張(zhang)(zhang)，將單個(ge)紙(zhi)(zhi)(zhi)張(zhang)(zhang)輸送到不(bu)(bu)同(tong)的(de)(de)顏(yan)色(se)集料裝(zhuang)(zhuang)置或引導紙(zhi)(zhi)(zhi)張(zhang)(zhang)通(tong)過(guo)印(yin)刷(shua)機(ji)(ji)(ji)。所(suo)有這些應用(yong)在不(bu)(bu)同(tong)的(de)(de)壓(ya)(ya)力時都需(xu)要不(bu)(bu)同(tong)的(de)(de)空(kong)氣量。印(yin)刷(shua)機(ji)(ji)(ji)的(de)(de)紙(zhi)(zhi)(zhi)張(zhang)(zhang)使(shi)用(yong)排起可進行分(fen)離，對齊及分(fen)送等作業。如(ru)(ru)果有兩三(san)臺印(yin)刷(shua)機(ji)(ji)(ji)，建議配(pei)(pei)個(ge)真(zhen)(zhen)(zhen)(zhen)空(kong)系統(tong)(tong)。兩臺以下，就(jiu)配(pei)(pei)真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)就(jiu)行了。印(yin)刷(shua)機(ji)(ji)(ji)選用(yong)真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)一般是無油泵(beng)(beng)，常用(yong)最多是：干式(shi)螺桿(gan)真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)、有些工藝(yi)不(bu)(bu)同(tong)也有選用(yong)油式(shi)旋片泵(beng)(beng)，干泵(beng)(beng)耗(hao)材(cai)比(bi)(bi)較(jiao)(jiao)少(shao)、日常維護保養比(bi)(bi)較(jiao)(jiao)方便。如(ru)(ru)選用(yong)真(zhen)(zhen)(zhen)(zhen)空(kong)系統(tong)(tong)比(bi)(bi)較(jiao)(jiao)節能，也減少(shao)日后的(de)(de)配(pei)(pei)件維護費。并(bing)且真(zhen)(zhen)(zhen)(zhen)空(kong)系統(tong)(tong)沒(mei)放車間(jian)(jian)，夏天不(bu)(bu)會過(guo)熱，增加空(kong)調的(de)(de)功率，節省資(zi)源。也不(bu)(bu)會給(gei)(gei)車間(jian)(jian)產生(sheng)噪音。真(zhen)(zhen)(zhen)(zhen)空(kong)與(yu)壓(ya)(ya)力廣泛應用(yong)于印(yin)后設備。例如(ru)(ru)，側流式(shi)鼓(gu)風機(ji)(ji)(ji)用(yong)于折疊和切(qie)割(ge)機(ji)(ji)(ji)；真(zhen)(zhen)(zhen)(zhen)空(kong)壓(ya)(ya)力復合泵(beng)(beng)和真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)與(yu)壓(ya)(ya)縮機(ji)(ji)(ji)用(yong)于配(pei)(pei)頁和書籍(ji)裝(zhuang)(zhuang)訂機(ji)(ji)(ji)；以及離心風機(ji)(ji)(ji)用(yong)于清除廢紙(zhi)(zhi)(zhi)等。
