真(zhen)空(kong)泵在(zai)工(gong)作(zuo)(zuo)中如果跳了闸，会使(shi)我(wo)们的(de)工(gong)作(zuo)(zuo)中断，浪(lang)费了时间，那(nei)真(zhen)空(kong)泵跳闸的(de)原因是(shi)什(shen)么?应(ying)该如何解决呢?

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(zhen)(zhen)空(kong)泵(beng)电(dian)(dian)机接在两相电(dian)(dian)源(yuan)上，未启(qi)用三(san)相电(dian)(dian)源(yuan)，可(ke)接通真(zhen)(zhen)空(kong)泵(beng)三(san)相电(dian)(dian)源(yuan)即可(ke)。开(kai)机前(qian)可(ke)认真(zhen)(zhen)核对(dui)产(chan)品(pin)规格型号，功率大小(xiao)电(dian)(dian)压(ya)电(dian)(dian)流等情况。或清相关的专业人士来接通电(dian)(dian)源(yuan)。

3.电(dian)(dian)(dian)机(ji)(ji)超(chao)负(fu)荷工(gong)(gong)作(zuo)。真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)电(dian)(dian)(dian)机(ji)(ji)超(chao)负(fu)荷工(gong)(gong)作(zuo)，这个(ge)(ge)时(shi)候电(dian)(dian)(dian)机(ji)(ji)的(de)(de)电(dian)(dian)(dian)流(liu)(liu)肯定会(hui)(hui)(hui)过(guo)高，如超(chao)过(guo)电(dian)(dian)(dian)控箱或继(ji)点保护器(qi)设(she)置的(de)(de)电(dian)(dian)(dian)流(liu)(liu)时(shi)，真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)会(hui)(hui)(hui)自(zi)行跳(tiao)闸，此时(shi)为真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)正常(chang)现(xian)象，可调高电(dian)(dian)(dian)流(liu)(liu)保护上(shang)限来解决跳(tiao)闸现(xian)象。但是(shi)(shi)(shi)要(yao)(yao)考虑电(dian)(dian)(dian)机(ji)(ji)额(e)定电(dian)(dian)(dian)流(liu)(liu)的(de)(de)大小(xiao)，如此时(shi)实际电(dian)(dian)(dian)流(liu)(liu)超(chao)过(guo)电(dian)(dian)(dian)机(ji)(ji)额(e)定电(dian)(dian)(dian)流(liu)(liu)，那么这个(ge)(ge)方法就(jiu)不能用了。这时(shi)要(yao)(yao)赶(gan)紧找出电(dian)(dian)(dian)机(ji)(ji)过(guo)载的(de)(de)原因解决问(wen)题(ti)。例如水(shui)环式(shi)(shi)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)超(chao)电(dian)(dian)(dian)流(liu)(liu)就(jiu)要(yao)(yao)考虑是(shi)(shi)(shi)否(fou)有(you)(you)异物进(jin)入(ru)了泵(beng)(beng)(beng)(beng)(beng)(beng)腔内，导(dao)致(zhi)电(dian)(dian)(dian)机(ji)(ji)超(chao)负(fu)荷的(de)(de)工(gong)(gong)作(zuo)，还有(you)(you)工(gong)(gong)作(zuo)液(ye)流(liu)(liu)量会(hui)(hui)(hui)不会(hui)(hui)(hui)过(guo)大，可相应调节。排(pai)气(qi)口(kou)是(shi)(shi)(shi)否(fou)压力过(guo)大，排(pai)气(qi)管(guan)路(lu)是(shi)(shi)(shi)否(fou)受(shou)阻，是(shi)(shi)(shi)否(fou)过(guo)高，过(guo)细等(deng)。而旋片式(shi)(shi)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)没有(you)(you)工(gong)(gong)作(zuo)液(ye)，可以不考虑以上(shang)问(wen)题(ti)。但旋片式(shi)(shi)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)需要(yao)(yao)加油(you)，此时(shi)要(yao)(yao)考虑泵(beng)(beng)(beng)(beng)(beng)(beng)腔内的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)油(you)是(shi)(shi)(shi)否(fou)乳(ru)化变，或有(you)(you)杂(za)物从(cong)进(jin)气(qi)口(kou)中(zhong)(zhong)进(jin)入(ru)。另外重(zhong)要(yao)(yao)的(de)(de)要(yao)(yao)检查进(jin)气(qi)管(guan)路(lu)是(shi)(shi)(shi)否(fou)存(cun)在泄漏，因为旋片式(shi)(shi)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)适应抽密(mi)封的(de)(de)系统，通大气(qi)使(shi)用会(hui)(hui)(hui)导(dao)致(zhi)电(dian)(dian)(dian)机(ji)(ji)超(chao)负(fu)荷而跳(tiao)闸。如果是(shi)(shi)(shi)罗(luo)茨(ci)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)或真(zhen)空(kong)(kong)(kong)(kong)(kong)机(ji)(ji)组的(de)(de)话，问(wen)题(ti)就(jiu)相对简单明了，因为大家都知道罗(luo)茨(ci)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)是(shi)(shi)(shi)增压泵(beng)(beng)(beng)(beng)(beng)(beng)不能单独使(shi)用，需要(yao)(yao)前级(ji)泵(beng)(beng)(beng)(beng)(beng)(beng)配合使(shi)用，如果没有(you)(you)达(da)到(dao)一(yi)定的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)度，罗(luo)茨(ci)泵(beng)(beng)(beng)(beng)(beng)(beng)启动(dong)后(hou)电(dian)(dian)(dian)机(ji)(ji)会(hui)(hui)(hui)超(chao)负(fu)荷，马上(shang)跳(tiao)闸。再者就(jiu)是(shi)(shi)(shi)基本的(de)(de)问(wen)题(ti)了比如被抽系统管(guan)路(lu)中(zhong)(zhong)是(shi)(shi)(shi)否(fou)有(you)(you)杂(za)物，焊渣，小(xiao)颗粒进(jin)入(ru)到(dao)泵(beng)(beng)(beng)(beng)(beng)(beng)腔，然后(hou)就(jiu)是(shi)(shi)(shi)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)油(you)了，罗(luo)茨(ci)水(shui)环真(zhen)空(kong)(kong)(kong)(kong)(kong)机(ji)(ji)组如果没有(you)(you)按照相应的(de)(de)启停顺序或是(shi)(shi)(shi)自(zi)动(dong)断电(dian)(dian)(dian)的(de)(de)情况(kuang)下水(shui)环泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)工(gong)(gong)作(zuo)液(ye)会(hui)(hui)(hui)受(shou)负(fu)压的(de)(de)影响返到(dao)罗(luo)茨(ci)泵(beng)(beng)(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)(beng)(beng)腔内，破坏了真(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)油(you)的(de)(de)性能，从(cong)而导(dao)致(zhi)罗(luo)茨(ci)泵(beng)(beng)(beng)(beng)(beng)(beng)超(chao)负(fu)荷工(gong)(gong)作(zuo)，超(chao)过(guo)额(e)定电(dian)(dian)(dian)流(liu)(liu)而跳(tiao)闸。
