真空泵(beng)(beng)在(zai)工作中如(ru)果(guo)跳了闸，会使(shi)我们的(de)工作中断，浪费了时间，那真空泵(beng)(beng)跳闸的(de)原因是什么?应该(gai)如(ru)何(he)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(beng)电(dian)机(ji)接在两(liang)相(xiang)(xiang)电(dian)源上，未启用三(san)相(xiang)(xiang)电(dian)源，可(ke)接通真空泵(beng)三(san)相(xiang)(xiang)电(dian)源即可(ke)。开机(ji)前(qian)可(ke)认(ren)真核对产品规(gui)格型号，功率大小电(dian)压(ya)电(dian)流等(deng)情况。或清相(xiang)(xiang)关的专业人士(shi)来(lai)接通电(dian)源。

3.电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)荷(he)工(gong)(gong)(gong)作(zuo)。真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)荷(he)工(gong)(gong)(gong)作(zuo)，这个(ge)时(shi)(shi)候电(dian)(dian)机(ji)(ji)的(de)(de)(de)电(dian)(dian)流(liu)(liu)肯定会(hui)(hui)(hui)过(guo)(guo)高(gao)，如(ru)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)控(kong)箱或(huo)(huo)继点保护(hu)器设置的(de)(de)(de)电(dian)(dian)流(liu)(liu)时(shi)(shi)，真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)会(hui)(hui)(hui)自(zi)行跳(tiao)闸(zha)，此(ci)时(shi)(shi)为(wei)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)正(zheng)常现象，可(ke)调(diao)高(gao)电(dian)(dian)流(liu)(liu)保护(hu)上(shang)限来解决(jue)跳(tiao)闸(zha)现象。但(dan)是(shi)(shi)(shi)(shi)(shi)(shi)要(yao)(yao)考(kao)虑电(dian)(dian)机(ji)(ji)额定电(dian)(dian)流(liu)(liu)的(de)(de)(de)大(da)小，如(ru)此(ci)时(shi)(shi)实际电(dian)(dian)流(liu)(liu)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)机(ji)(ji)额定电(dian)(dian)流(liu)(liu)，那(nei)么这个(ge)方法就(jiu)不(bu)(bu)能用了(le)(le)。这时(shi)(shi)要(yao)(yao)赶(gan)紧找出电(dian)(dian)机(ji)(ji)过(guo)(guo)载的(de)(de)(de)原因(yin)(yin)解决(jue)问题。例如(ru)水环式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)超(chao)(chao)(chao)电(dian)(dian)流(liu)(liu)就(jiu)要(yao)(yao)考(kao)虑是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)有(you)(you)(you)异物(wu)进(jin)(jin)入了(le)(le)泵(beng)(beng)(beng)(beng)(beng)腔(qiang)内，导(dao)致(zhi)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)荷(he)的(de)(de)(de)工(gong)(gong)(gong)作(zuo)，还有(you)(you)(you)工(gong)(gong)(gong)作(zuo)液(ye)流(liu)(liu)量会(hui)(hui)(hui)不(bu)(bu)会(hui)(hui)(hui)过(guo)(guo)大(da)，可(ke)相(xiang)应(ying)(ying)调(diao)节。排(pai)气口是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)压力(li)过(guo)(guo)大(da)，排(pai)气管路(lu)(lu)是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)受(shou)阻，是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)过(guo)(guo)高(gao)，过(guo)(guo)细(xi)等(deng)。而(er)旋(xuan)(xuan)片式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)没有(you)(you)(you)工(gong)(gong)(gong)作(zuo)液(ye)，可(ke)以不(bu)(bu)考(kao)虑以上(shang)问题。但(dan)旋(xuan)(xuan)片式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)需要(yao)(yao)加油，此(ci)时(shi)(shi)要(yao)(yao)考(kao)虑泵(beng)(beng)(beng)(beng)(beng)腔(qiang)内的(de)(de)(de)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)油是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)乳化(hua)变，或(huo)(huo)有(you)(you)(you)杂(za)物(wu)从(cong)(cong)进(jin)(jin)气口中(zhong)进(jin)(jin)入。另外(wai)重要(yao)(yao)的(de)(de)(de)要(yao)(yao)检查进(jin)(jin)气管路(lu)(lu)是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)存在泄漏，因(yin)(yin)为(wei)旋(xuan)(xuan)片式(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)适(shi)应(ying)(ying)抽密(mi)封的(de)(de)(de)系统(tong)，通(tong)大(da)气使(shi)用会(hui)(hui)(hui)导(dao)致(zhi)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)荷(he)而(er)跳(tiao)闸(zha)。如(ru)果是(shi)(shi)(shi)(shi)(shi)(shi)罗茨真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)或(huo)(huo)真(zhen)(zhen)空(kong)机(ji)(ji)组的(de)(de)(de)话，问题就(jiu)相(xiang)对简(jian)单(dan)(dan)明了(le)(le)，因(yin)(yin)为(wei)大(da)家都知道罗茨真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)是(shi)(shi)(shi)(shi)(shi)(shi)增(zeng)压泵(beng)(beng)(beng)(beng)(beng)不(bu)(bu)能单(dan)(dan)独使(shi)用，需要(yao)(yao)前级泵(beng)(beng)(beng)(beng)(beng)配合使(shi)用，如(ru)果没有(you)(you)(you)达到(dao)一(yi)定的(de)(de)(de)真(zhen)(zhen)空(kong)度，罗茨泵(beng)(beng)(beng)(beng)(beng)启动后电(dian)(dian)机(ji)(ji)会(hui)(hui)(hui)超(chao)(chao)(chao)负(fu)荷(he)，马(ma)上(shang)跳(tiao)闸(zha)。再者就(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)基本的(de)(de)(de)问题了(le)(le)比如(ru)被(bei)抽系统(tong)管路(lu)(lu)中(zhong)是(shi)(shi)(shi)(shi)(shi)(shi)否(fou)(fou)有(you)(you)(you)杂(za)物(wu)，焊渣，小颗粒进(jin)(jin)入到(dao)泵(beng)(beng)(beng)(beng)(beng)腔(qiang)，然后就(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)油了(le)(le)，罗茨水环真(zhen)(zhen)空(kong)机(ji)(ji)组如(ru)果没有(you)(you)(you)按照(zhao)相(xiang)应(ying)(ying)的(de)(de)(de)启停顺序或(huo)(huo)是(shi)(shi)(shi)(shi)(shi)(shi)自(zi)动断(duan)电(dian)(dian)的(de)(de)(de)情况下水环泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)工(gong)(gong)(gong)作(zuo)液(ye)会(hui)(hui)(hui)受(shou)负(fu)压的(de)(de)(de)影响(xiang)返到(dao)罗茨泵(beng)(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)(beng)腔(qiang)内，破坏了(le)(le)真(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)油的(de)(de)(de)性能，从(cong)(cong)而(er)导(dao)致(zhi)罗茨泵(beng)(beng)(beng)(beng)(beng)超(chao)(chao)(chao)负(fu)荷(he)工(gong)(gong)(gong)作(zuo)，超(chao)(chao)(chao)过(guo)(guo)额定电(dian)(dian)流(liu)(liu)而(er)跳(tiao)闸(zha)。
