真空(kong)泵在工(gong)作(zuo)中如(ru)果跳了闸(zha)，会使我们(men)的(de)(de)工(gong)作(zuo)中断，浪费了时间，那真空(kong)泵跳闸(zha)的(de)(de)原因是什么?应该如(ru)何解(jie)决呢?

1.真空泵长时间停用，如果停用真空泵时间过长电机负载会导致暂时性电流过高。无油式真空泵解决办法：换干净的真空泵油，关掉进气口与被抽系统前的阀门，不接系统运转一段时间。水环式真空泵解决办法：开机前可手动盘车，如在没有进异物的情况下，可加入除锈剂，或15%的草酸浸泡半个小时左右。

2.真空泵电(dian)机接(jie)在(zai)两相(xiang)电(dian)源上，未启用三相(xiang)电(dian)源，可(ke)接(jie)通真空泵三相(xiang)电(dian)源即可(ke)。开(kai)机前(qian)可(ke)认真核对产品(pin)规格型号，功率大小电(dian)压电(dian)流等情(qing)况。或清相(xiang)关的(de)专业人士来(lai)接(jie)通电(dian)源。

3.电(dian)(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷(he)(he)工(gong)(gong)作(zuo)(zuo)。真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)电(dian)(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷(he)(he)工(gong)(gong)作(zuo)(zuo)，这个时候电(dian)(dian)(dian)(dian)机(ji)(ji)的(de)(de)电(dian)(dian)(dian)(dian)流肯定(ding)会(hui)过(guo)高，如(ru)超(chao)(chao)(chao)过(guo)电(dian)(dian)(dian)(dian)控(kong)箱或继点保(bao)护器设置的(de)(de)电(dian)(dian)(dian)(dian)流时，真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)会(hui)自(zi)行跳(tiao)(tiao)(tiao)闸，此时为真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)正常现象(xiang)，可(ke)调高电(dian)(dian)(dian)(dian)流保(bao)护上限来解(jie)决跳(tiao)(tiao)(tiao)闸现象(xiang)。但是(shi)(shi)要(yao)考虑(lv)电(dian)(dian)(dian)(dian)机(ji)(ji)额定(ding)电(dian)(dian)(dian)(dian)流的(de)(de)大(da)小，如(ru)此时实(shi)际电(dian)(dian)(dian)(dian)流超(chao)(chao)(chao)过(guo)电(dian)(dian)(dian)(dian)机(ji)(ji)额定(ding)电(dian)(dian)(dian)(dian)流，那(nei)么(me)这个方(fang)法(fa)就(jiu)(jiu)不(bu)能(neng)(neng)用(yong)了(le)。这时要(yao)赶紧找出电(dian)(dian)(dian)(dian)机(ji)(ji)过(guo)载的(de)(de)原因(yin)(yin)解(jie)决问(wen)题(ti)(ti)。例如(ru)水(shui)环式真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)超(chao)(chao)(chao)电(dian)(dian)(dian)(dian)流就(jiu)(jiu)要(yao)考虑(lv)是(shi)(shi)否(fou)(fou)有(you)异物进(jin)入了(le)泵(beng)腔内(nei)，导致电(dian)(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷(he)(he)的(de)(de)工(gong)(gong)作(zuo)(zuo)，还有(you)工(gong)(gong)作(zuo)(zuo)液流量会(hui)不(bu)会(hui)过(guo)大(da)，可(ke)相应调节。排气口(kou)是(shi)(shi)否(fou)(fou)压(ya)力过(guo)大(da)，排气管路(lu)是(shi)(shi)否(fou)(fou)受(shou)阻，是(shi)(shi)否(fou)(fou)过(guo)高，过(guo)细等。而(er)旋(xuan)片(pian)(pian)(pian)式真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)没有(you)工(gong)(gong)作(zuo)(zuo)液，可(ke)以(yi)(yi)不(bu)考虑(lv)以(yi)(yi)上问(wen)题(ti)(ti)。但旋(xuan)片(pian)(pian)(pian)式真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)需要(yao)加油(you)，此时要(yao)考虑(lv)泵(beng)腔内(nei)的(de)(de)真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)油(you)是(shi)(shi)否(fou)(fou)乳化变，或有(you)杂(za)物从进(jin)气口(kou)中进(jin)入。另(ling)外重要(yao)的(de)(de)要(yao)检查(cha)进(jin)气管路(lu)是(shi)(shi)否(fou)(fou)存在泄(xie)漏，因(yin)(yin)为旋(xuan)片(pian)(pian)(pian)式真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)适应抽(chou)密封(feng)的(de)(de)系统，通大(da)气使用(yong)会(hui)导致电(dian)(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷(he)(he)而(er)跳(tiao)(tiao)(tiao)闸。如(ru)果是(shi)(shi)罗茨真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)或真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)机(ji)(ji)组的(de)(de)话，问(wen)题(ti)(ti)就(jiu)(jiu)相对简单(dan)(dan)明了(le)，因(yin)(yin)为大(da)家都知(zhi)道(dao)罗茨真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)是(shi)(shi)增(zeng)压(ya)泵(beng)不(bu)能(neng)(neng)单(dan)(dan)独(du)使用(yong)，需要(yao)前级泵(beng)配合使用(yong)，如(ru)果没有(you)达到一(yi)定(ding)的(de)(de)真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)度，罗茨泵(beng)启(qi)动(dong)(dong)后(hou)电(dian)(dian)(dian)(dian)机(ji)(ji)会(hui)超(chao)(chao)(chao)负荷(he)(he)，马上跳(tiao)(tiao)(tiao)闸。再者就(jiu)(jiu)是(shi)(shi)基本的(de)(de)问(wen)题(ti)(ti)了(le)比如(ru)被抽(chou)系统管路(lu)中是(shi)(shi)否(fou)(fou)有(you)杂(za)物，焊渣，小颗粒进(jin)入到泵(beng)腔，然后(hou)就(jiu)(jiu)是(shi)(shi)真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)油(you)了(le)，罗茨水(shui)环真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)机(ji)(ji)组如(ru)果没有(you)按照相应的(de)(de)启(qi)停(ting)顺序或是(shi)(shi)自(zi)动(dong)(dong)断电(dian)(dian)(dian)(dian)的(de)(de)情况下水(shui)环泵(beng)的(de)(de)工(gong)(gong)作(zuo)(zuo)液会(hui)受(shou)负压(ya)的(de)(de)影响(xiang)返到罗茨泵(beng)泵(beng)腔内(nei)，破坏了(le)真空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)油(you)的(de)(de)性(xing)能(neng)(neng)，从而(er)导致罗茨泵(beng)超(chao)(chao)(chao)负荷(he)(he)工(gong)(gong)作(zuo)(zuo)，超(chao)(chao)(chao)过(guo)额定(ding)电(dian)(dian)(dian)(dian)流而(er)跳(tiao)(tiao)(tiao)闸。
