真空泵在工(gong)作中如(ru)果跳了(le)闸，会使我们的工(gong)作中断，浪(lang)费了(le)时间，那(nei)真空泵跳闸的原因是什么?应该如(ru)何解决呢(ni)?

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(zhen)空泵电(dian)机接(jie)在两相电(dian)源上，未启用(yong)三相电(dian)源，可接(jie)通真(zhen)空泵三相电(dian)源即可。开机前(qian)可认真(zhen)核对(dui)产品(pin)规(gui)格型(xing)号，功率(lv)大小电(dian)压电(dian)流等情(qing)况。或清相关的专业人(ren)士(shi)来接(jie)通电(dian)源。

3.电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)工(gong)作(zuo)(zuo)。真(zhen)空(kong)(kong)(kong)泵(beng)(beng)电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)工(gong)作(zuo)(zuo)，这个(ge)时(shi)(shi)候电(dian)(dian)(dian)机(ji)(ji)的(de)(de)(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)流(liu)(liu)(liu)肯定会(hui)过(guo)(guo)高(gao)，如(ru)超(chao)(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)控(kong)箱或(huo)继点保护(hu)(hu)器设置(zhi)的(de)(de)(de)(de)(de)(de)(de)(de)电(dian)(dian)(dian)流(liu)(liu)(liu)时(shi)(shi)，真(zhen)空(kong)(kong)(kong)泵(beng)(beng)会(hui)自行(xing)跳(tiao)闸，此时(shi)(shi)为真(zhen)空(kong)(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)(de)正(zheng)常现(xian)象(xiang)，可(ke)调(diao)高(gao)电(dian)(dian)(dian)流(liu)(liu)(liu)保护(hu)(hu)上(shang)限来解(jie)决跳(tiao)闸现(xian)象(xiang)。但(dan)是(shi)(shi)(shi)要(yao)(yao)考虑电(dian)(dian)(dian)机(ji)(ji)额定电(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)(de)(de)大(da)(da)小，如(ru)此时(shi)(shi)实际电(dian)(dian)(dian)流(liu)(liu)(liu)超(chao)(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)机(ji)(ji)额定电(dian)(dian)(dian)流(liu)(liu)(liu)，那么这个(ge)方法就(jiu)不(bu)(bu)能用(yong)了(le)(le)。这时(shi)(shi)要(yao)(yao)赶紧找出电(dian)(dian)(dian)机(ji)(ji)过(guo)(guo)载的(de)(de)(de)(de)(de)(de)(de)(de)原因解(jie)决问(wen)(wen)题(ti)。例如(ru)水环(huan)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)超(chao)(chao)(chao)(chao)电(dian)(dian)(dian)流(liu)(liu)(liu)就(jiu)要(yao)(yao)考虑是(shi)(shi)(shi)否(fou)有(you)(you)异物(wu)进入了(le)(le)泵(beng)(beng)腔内(nei)，导致电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)的(de)(de)(de)(de)(de)(de)(de)(de)工(gong)作(zuo)(zuo)，还有(you)(you)工(gong)作(zuo)(zuo)液流(liu)(liu)(liu)量会(hui)不(bu)(bu)会(hui)过(guo)(guo)大(da)(da)，可(ke)相(xiang)应调(diao)节(jie)。排气(qi)口是(shi)(shi)(shi)否(fou)压(ya)力过(guo)(guo)大(da)(da)，排气(qi)管(guan)(guan)路是(shi)(shi)(shi)否(fou)受(shou)阻，是(shi)(shi)(shi)否(fou)过(guo)(guo)高(gao)，过(guo)(guo)细等。而旋片(pian)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)没有(you)(you)工(gong)作(zuo)(zuo)液，可(ke)以不(bu)(bu)考虑以上(shang)问(wen)(wen)题(ti)。但(dan)旋片(pian)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)需(xu)要(yao)(yao)加(jia)油，此时(shi)(shi)要(yao)(yao)考虑泵(beng)(beng)腔内(nei)的(de)(de)(de)(de)(de)(de)(de)(de)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)油是(shi)(shi)(shi)否(fou)乳(ru)化变，或(huo)有(you)(you)杂物(wu)从(cong)进气(qi)口中(zhong)进入。另外重要(yao)(yao)的(de)(de)(de)(de)(de)(de)(de)(de)要(yao)(yao)检查(cha)进气(qi)管(guan)(guan)路是(shi)(shi)(shi)否(fou)存(cun)在泄漏，因为旋片(pian)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)适应抽(chou)密封的(de)(de)(de)(de)(de)(de)(de)(de)系统，通大(da)(da)气(qi)使(shi)用(yong)会(hui)导致电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)而跳(tiao)闸。如(ru)果(guo)(guo)(guo)是(shi)(shi)(shi)罗(luo)(luo)(luo)茨(ci)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)或(huo)真(zhen)空(kong)(kong)(kong)机(ji)(ji)组的(de)(de)(de)(de)(de)(de)(de)(de)话，问(wen)(wen)题(ti)就(jiu)相(xiang)对(dui)简(jian)单明了(le)(le)，因为大(da)(da)家都知道罗(luo)(luo)(luo)茨(ci)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)是(shi)(shi)(shi)增压(ya)泵(beng)(beng)不(bu)(bu)能单独使(shi)用(yong)，需(xu)要(yao)(yao)前级(ji)泵(beng)(beng)配合(he)使(shi)用(yong)，如(ru)果(guo)(guo)(guo)没有(you)(you)达到一定的(de)(de)(de)(de)(de)(de)(de)(de)真(zhen)空(kong)(kong)(kong)度，罗(luo)(luo)(luo)茨(ci)泵(beng)(beng)启(qi)动(dong)(dong)后(hou)(hou)电(dian)(dian)(dian)机(ji)(ji)会(hui)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)，马上(shang)跳(tiao)闸。再(zai)者就(jiu)是(shi)(shi)(shi)基本(ben)的(de)(de)(de)(de)(de)(de)(de)(de)问(wen)(wen)题(ti)了(le)(le)比如(ru)被抽(chou)系统管(guan)(guan)路中(zhong)是(shi)(shi)(shi)否(fou)有(you)(you)杂物(wu)，焊(han)渣，小颗粒(li)进入到泵(beng)(beng)腔，然(ran)后(hou)(hou)就(jiu)是(shi)(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)油了(le)(le)，罗(luo)(luo)(luo)茨(ci)水环(huan)真(zhen)空(kong)(kong)(kong)机(ji)(ji)组如(ru)果(guo)(guo)(guo)没有(you)(you)按照相(xiang)应的(de)(de)(de)(de)(de)(de)(de)(de)启(qi)停顺(shun)序或(huo)是(shi)(shi)(shi)自动(dong)(dong)断电(dian)(dian)(dian)的(de)(de)(de)(de)(de)(de)(de)(de)情况下水环(huan)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)(de)工(gong)作(zuo)(zuo)液会(hui)受(shou)负(fu)压(ya)的(de)(de)(de)(de)(de)(de)(de)(de)影响返到罗(luo)(luo)(luo)茨(ci)泵(beng)(beng)泵(beng)(beng)腔内(nei)，破坏了(le)(le)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)油的(de)(de)(de)(de)(de)(de)(de)(de)性能，从(cong)而导致罗(luo)(luo)(luo)茨(ci)泵(beng)(beng)超(chao)(chao)(chao)(chao)负(fu)荷(he)(he)工(gong)作(zuo)(zuo)，超(chao)(chao)(chao)(chao)过(guo)(guo)额定电(dian)(dian)(dian)流(liu)(liu)(liu)而跳(tiao)闸。
