真(zhen)空泵在工作中如果跳了闸(zha)，会(hui)使我们(men)的工作中断，浪(lang)费了时间，那真(zhen)空泵跳闸(zha)的原因是(shi)什么?应(ying)该如何解决呢(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.真空泵(beng)电(dian)(dian)机接在两相(xiang)(xiang)电(dian)(dian)源(yuan)上，未启用三(san)相(xiang)(xiang)电(dian)(dian)源(yuan)，可接通真空泵(beng)三(san)相(xiang)(xiang)电(dian)(dian)源(yuan)即可。开机前(qian)可认真核对产品(pin)规格型号，功率大小电(dian)(dian)压电(dian)(dian)流等情(qing)况。或清相(xiang)(xiang)关的(de)专业人士来(lai)接通电(dian)(dian)源(yuan)。

3.电(dian)(dian)(dian)(dian)机超(chao)(chao)负(fu)(fu)荷(he)工作(zuo)(zuo)。真(zhen)空泵(beng)(beng)(beng)(beng)电(dian)(dian)(dian)(dian)机超(chao)(chao)负(fu)(fu)荷(he)工作(zuo)(zuo)，这个时(shi)候(hou)电(dian)(dian)(dian)(dian)机的(de)(de)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)肯定(ding)会(hui)(hui)过高，如(ru)超(chao)(chao)过电(dian)(dian)(dian)(dian)控箱(xiang)或继点保(bao)护(hu)器(qi)设置(zhi)的(de)(de)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)时(shi)，真(zhen)空泵(beng)(beng)(beng)(beng)会(hui)(hui)自行跳(tiao)闸(zha)(zha)，此时(shi)为真(zhen)空泵(beng)(beng)(beng)(beng)的(de)(de)正(zheng)常现象，可调(diao)(diao)高电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)保(bao)护(hu)上(shang)限(xian)来解(jie)决(jue)跳(tiao)闸(zha)(zha)现象。但(dan)是(shi)(shi)要(yao)考(kao)虑(lv)电(dian)(dian)(dian)(dian)机额定(ding)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)大(da)小，如(ru)此时(shi)实际电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)超(chao)(chao)过电(dian)(dian)(dian)(dian)机额定(ding)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，那么这个方(fang)法就不能用了(le)。这时(shi)要(yao)赶(gan)紧找(zhao)出电(dian)(dian)(dian)(dian)机过载的(de)(de)原因解(jie)决(jue)问题(ti)。例如(ru)水(shui)环式(shi)真(zhen)空泵(beng)(beng)(beng)(beng)超(chao)(chao)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)就要(yao)考(kao)虑(lv)是(shi)(shi)否有(you)异物(wu)(wu)进(jin)(jin)(jin)入了(le)泵(beng)(beng)(beng)(beng)腔内，导致(zhi)电(dian)(dian)(dian)(dian)机超(chao)(chao)负(fu)(fu)荷(he)的(de)(de)工作(zuo)(zuo)，还有(you)工作(zuo)(zuo)液流(liu)(liu)(liu)量会(hui)(hui)不会(hui)(hui)过大(da)，可相应(ying)调(diao)(diao)节(jie)。排(pai)气口是(shi)(shi)否压(ya)力过大(da)，排(pai)气管路(lu)是(shi)(shi)否受(shou)阻，是(shi)(shi)否过高，过细等。而旋(xuan)片式(shi)真(zhen)空泵(beng)(beng)(beng)(beng)没(mei)有(you)工作(zuo)(zuo)液，可以不考(kao)虑(lv)以上(shang)问题(ti)。但(dan)旋(xuan)片式(shi)真(zhen)空泵(beng)(beng)(beng)(beng)需(xu)要(yao)加油(you)(you)，此时(shi)要(yao)考(kao)虑(lv)泵(beng)(beng)(beng)(beng)腔内的(de)(de)真(zhen)空泵(beng)(beng)(beng)(beng)油(you)(you)是(shi)(shi)否乳化变，或有(you)杂物(wu)(wu)从进(jin)(jin)(jin)气口中进(jin)(jin)(jin)入。另外(wai)重要(yao)的(de)(de)要(yao)检查进(jin)(jin)(jin)气管路(lu)是(shi)(shi)否存在泄(xie)漏，因为旋(xuan)片式(shi)真(zhen)空泵(beng)(beng)(beng)(beng)适(shi)应(ying)抽(chou)密(mi)封的(de)(de)系(xi)(xi)统，通大(da)气使(shi)用会(hui)(hui)导致(zhi)电(dian)(dian)(dian)(dian)机超(chao)(chao)负(fu)(fu)荷(he)而跳(tiao)闸(zha)(zha)。如(ru)果(guo)是(shi)(shi)罗茨(ci)真(zhen)空泵(beng)(beng)(beng)(beng)或真(zhen)空机组(zu)的(de)(de)话，问题(ti)就相对简单明(ming)了(le)，因为大(da)家都知道(dao)罗茨(ci)真(zhen)空泵(beng)(beng)(beng)(beng)是(shi)(shi)增压(ya)泵(beng)(beng)(beng)(beng)不能单独使(shi)用，需(xu)要(yao)前(qian)级泵(beng)(beng)(beng)(beng)配(pei)合(he)使(shi)用，如(ru)果(guo)没(mei)有(you)达到(dao)一定(ding)的(de)(de)真(zhen)空度，罗茨(ci)泵(beng)(beng)(beng)(beng)启(qi)(qi)动后(hou)电(dian)(dian)(dian)(dian)机会(hui)(hui)超(chao)(chao)负(fu)(fu)荷(he)，马上(shang)跳(tiao)闸(zha)(zha)。再(zai)者就是(shi)(shi)基本的(de)(de)问题(ti)了(le)比如(ru)被抽(chou)系(xi)(xi)统管路(lu)中是(shi)(shi)否有(you)杂物(wu)(wu)，焊渣，小颗(ke)粒进(jin)(jin)(jin)入到(dao)泵(beng)(beng)(beng)(beng)腔，然后(hou)就是(shi)(shi)真(zhen)空泵(beng)(beng)(beng)(beng)油(you)(you)了(le)，罗茨(ci)水(shui)环真(zhen)空机组(zu)如(ru)果(guo)没(mei)有(you)按照相应(ying)的(de)(de)启(qi)(qi)停顺序(xu)或是(shi)(shi)自动断电(dian)(dian)(dian)(dian)的(de)(de)情(qing)况(kuang)下水(shui)环泵(beng)(beng)(beng)(beng)的(de)(de)工作(zuo)(zuo)液会(hui)(hui)受(shou)负(fu)(fu)压(ya)的(de)(de)影(ying)响返到(dao)罗茨(ci)泵(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)腔内，破(po)坏了(le)真(zhen)空泵(beng)(beng)(beng)(beng)油(you)(you)的(de)(de)性能，从而导致(zhi)罗茨(ci)泵(beng)(beng)(beng)(beng)超(chao)(chao)负(fu)(fu)荷(he)工作(zuo)(zuo)，超(chao)(chao)过额定(ding)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)而跳(tiao)闸(zha)(zha)。
