水(shui)環真空泵使用常見故(gu)障及(ji)維修方法(fa)？

日期： 2018-05-25

用戶在使用廠家直銷的水環真空泵工作的過程中,由于連續使(shi)用、作業環(huan)(huan)境、操(cao)作技術等(deng)方面的原因，致(zhi)使(shi)水(shui)環(huan)(huan)真空泵出現類似盤(pan)車(che)困難(nan)、電機運(yun)轉不暢、啟(qi)動聲音(yin)異常、流(liu)量不足等(deng)故障(zhang),下(xia)面我們結合實際情況給出水(shui)環(huan)(huan)真空泵使(shi)用常見(jian)故障(zhang)維(wei)修方法(fa)。

水環真空泵使用常見故障及維修方法

1：水環真空泵盤車困難：

出現盤車困(kun)難(nan)的大(da)多為(wei)出廠后長(chang)久未(wei)進(jin)入(ru)工作(zuo)狀態的水(shui)(shui)環真空泵出現端(duan)面銹蝕，需要在(zai)(zai)泵腔(qiang)內充入(ru)草酸浸(jin)泡(pao)半(ban)個小時，松動螺(luo)栓后進(jin)行(xing)盤車順暢后復將泵蓋(gai)螺(luo)栓均勻鎖(suo)緊。若為(wei)使用(yong)狀態下的水(shui)(shui)環真空泵，用(yong)戶需對泵腔(qiang)水(shui)(shui)溫和污垢(gou)清理情況進(jin)行(xing)檢查，除在(zai)(zai)泵腔(qiang)內浸(jin)泡(pao)草酸之外，還應改進(jin)工藝盡量降低(di)水(shui)(shui)溫、減少工作(zuo)液(ye)污垢(gou)。

2：水環真空泵啟動聲音異常：

啟動(dong)聲(sheng)音異常(chang)時用(yong)戶(hu)(hu)應將供電(dian)電(dian)壓、電(dian)機接線等逐一(yi)排查無誤后，對長期(qi)未(wei)用(yong)的水(shui)環(huan)真(zhen)空泵(beng)用(yong)戶(hu)(hu)應進開(kai)(kai)蓋除(chu)(chu)去雜質及(ji)異物，對發生銹蝕的應添加除(chu)(chu)銹劑或人工除(chu)(chu)銹。如聲(sheng)音仍(reng)未(wei)正常(chang)，用(yong)戶(hu)(hu)應打開(kai)(kai)排污口(kou)放(fang)出適(shi)量工作液，原(yuan)因可能(neng)是工作液充滿(man)泵(beng)腔滿(man)水(shui)啟動(dong)。

3：水環真空泵溫度過高:

水環真空泵(beng)溫度過(guo)高應(ying)(ying)根據工作(zuo)液(ye)(ye)和氣體(ti)的(de)(de)實際情(qing)況(kuang)進行解決(jue)。如果是(shi)(shi)工作(zuo)液(ye)(ye)入口(kou)溫度過(guo)高或供應(ying)(ying)量過(guo)小(xiao)造成的(de)(de)水環真空泵(beng)溫度過(guo)高，用戶(hu)應(ying)(ying)想辦法降低工作(zuo)液(ye)(ye)溫度或增加(jia)工作(zuo)液(ye)(ye)供應(ying)(ying)量。如果是(shi)(shi)吸入氣體(ti)溫度過(guo)高導(dao)致水環真空泵(beng)溫度過(guo)高的(de)(de)，用戶(hu)應(ying)(ying)想方(fang)法降低吸入氣體(ti)溫度；抽除(chu)氣體(ti)在壓縮腔(qiang)放出汽化熱(re)，用戶(hu)應(ying)(ying)在泵(beng)入口(kou)前冷凝(ning)可凝(ning)性氣體(ti)。

4：水環真空泵電機過熱：

出(chu)現電(dian)機過(guo)熱時用戶(hu)應將(jiang)將(jiang)電(dian)機缺相、接線(xian)牢固(gu)、排(pai)氣孔(kong)堵塞、葉(xie)輪拖(tuo)動(dong)等逐一排(pai)查無誤后(hou)，重點檢(jian)查供(gong)水(shui)(shui)量導致電(dian)機超載(zai)，并將(jiang)供(gong)水(shui)(shui)量降到參數設(she)置范圍。

以上是(shi)水(shui)環真空(kong)(kong)泵在日常使(shi)用(yong)過程中(zhong)經常出現的(de)(de)幾(ji)種故(gu)障及簡易維修方法(fa)。相(xiang)對而言，高效的(de)(de)水(shui)環真空(kong)(kong)泵出故(gu)障的(de)(de)概率還是(shi)相(xiang)對較低的(de)(de)。水(shui)環真空(kong)(kong)泵在正常作業過程中(zhong)，用(yong)戶及設備(bei)管(guan)理人員應該多留心、多觀察(cha)、勤保(bao)管(guan)，如果(guo)出現常用(yong)故(gu)障，可以采用(yong)上述方法(fa)去(qu)解決。對有超過常見故(gu)障又不熟悉技術(shu)參數(shu)的(de)(de)，用(yong)戶切忌盲(mang)目(mu)操作，應找(zhao)專業人士去(qu)維修。
