真(zhen)空泵(beng)(beng)在(zai)工作中如果跳了(le)闸，会使我们的工作中断，浪费(fei)了(le)时间，那真(zhen)空泵(beng)(beng)跳闸的原因是什么?应该如何(he)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)泵电(dian)机接(jie)在两相(xiang)(xiang)电(dian)源上(shang)，未(wei)启(qi)用三(san)相(xiang)(xiang)电(dian)源，可接(jie)通(tong)真(zhen)(zhen)空(kong)泵三(san)相(xiang)(xiang)电(dian)源即可。开机前可认(ren)真(zhen)(zhen)核对产品(pin)规(gui)格型(xing)号(hao)，功率大小(xiao)电(dian)压电(dian)流等情况。或(huo)清相(xiang)(xiang)关的专(zhuan)业人士(shi)来接(jie)通(tong)电(dian)源。

3.电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)(fu)荷工(gong)作(zuo)(zuo)(zuo)。真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)(fu)荷工(gong)作(zuo)(zuo)(zuo)，这(zhei)个时(shi)(shi)(shi)候电(dian)(dian)机(ji)(ji)的(de)(de)(de)(de)(de)(de)电(dian)(dian)流肯(ken)定(ding)会(hui)(hui)(hui)过(guo)(guo)(guo)高(gao)，如(ru)(ru)超(chao)(chao)(chao)过(guo)(guo)(guo)电(dian)(dian)控箱(xiang)或(huo)继点(dian)保护器设置的(de)(de)(de)(de)(de)(de)电(dian)(dian)流时(shi)(shi)(shi)，真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)会(hui)(hui)(hui)自行(xing)跳(tiao)(tiao)闸(zha)(zha)，此(ci)时(shi)(shi)(shi)为(wei)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)正常现(xian)(xian)象，可(ke)调高(gao)电(dian)(dian)流保护上(shang)限来解决(jue)(jue)跳(tiao)(tiao)闸(zha)(zha)现(xian)(xian)象。但是(shi)(shi)要(yao)(yao)考虑电(dian)(dian)机(ji)(ji)额定(ding)电(dian)(dian)流的(de)(de)(de)(de)(de)(de)大(da)小，如(ru)(ru)此(ci)时(shi)(shi)(shi)实际电(dian)(dian)流超(chao)(chao)(chao)过(guo)(guo)(guo)电(dian)(dian)机(ji)(ji)额定(ding)电(dian)(dian)流，那么这(zhei)个方法就(jiu)不(bu)能用(yong)了。这(zhei)时(shi)(shi)(shi)要(yao)(yao)赶紧找出电(dian)(dian)机(ji)(ji)过(guo)(guo)(guo)载的(de)(de)(de)(de)(de)(de)原因(yin)(yin)解决(jue)(jue)问(wen)(wen)题(ti)。例如(ru)(ru)水环式(shi)(shi)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)超(chao)(chao)(chao)电(dian)(dian)流就(jiu)要(yao)(yao)考虑是(shi)(shi)否(fou)(fou)(fou)有异物(wu)进(jin)入(ru)(ru)了泵(beng)(beng)(beng)(beng)(beng)腔内(nei)，导致(zhi)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)(fu)荷的(de)(de)(de)(de)(de)(de)工(gong)作(zuo)(zuo)(zuo)，还有工(gong)作(zuo)(zuo)(zuo)液流量会(hui)(hui)(hui)不(bu)会(hui)(hui)(hui)过(guo)(guo)(guo)大(da)，可(ke)相(xiang)应(ying)(ying)调节。排气(qi)口是(shi)(shi)否(fou)(fou)(fou)压力过(guo)(guo)(guo)大(da)，排气(qi)管路(lu)是(shi)(shi)否(fou)(fou)(fou)受(shou)阻，是(shi)(shi)否(fou)(fou)(fou)过(guo)(guo)(guo)高(gao)，过(guo)(guo)(guo)细等。而(er)旋(xuan)片(pian)式(shi)(shi)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)没(mei)有工(gong)作(zuo)(zuo)(zuo)液，可(ke)以不(bu)考虑以上(shang)问(wen)(wen)题(ti)。但旋(xuan)片(pian)式(shi)(shi)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)需要(yao)(yao)加油，此(ci)时(shi)(shi)(shi)要(yao)(yao)考虑泵(beng)(beng)(beng)(beng)(beng)腔内(nei)的(de)(de)(de)(de)(de)(de)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油是(shi)(shi)否(fou)(fou)(fou)乳化变，或(huo)有杂物(wu)从(cong)(cong)进(jin)气(qi)口中进(jin)入(ru)(ru)。另外重要(yao)(yao)的(de)(de)(de)(de)(de)(de)要(yao)(yao)检查进(jin)气(qi)管路(lu)是(shi)(shi)否(fou)(fou)(fou)存在泄漏，因(yin)(yin)为(wei)旋(xuan)片(pian)式(shi)(shi)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)适应(ying)(ying)抽密封的(de)(de)(de)(de)(de)(de)系统，通大(da)气(qi)使(shi)用(yong)会(hui)(hui)(hui)导致(zhi)电(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)(fu)荷而(er)跳(tiao)(tiao)闸(zha)(zha)。如(ru)(ru)果是(shi)(shi)罗(luo)茨(ci)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)或(huo)真空(kong)(kong)(kong)机(ji)(ji)组的(de)(de)(de)(de)(de)(de)话，问(wen)(wen)题(ti)就(jiu)相(xiang)对简单明(ming)了，因(yin)(yin)为(wei)大(da)家都(dou)知道罗(luo)茨(ci)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)是(shi)(shi)增压泵(beng)(beng)(beng)(beng)(beng)不(bu)能单独使(shi)用(yong)，需要(yao)(yao)前级泵(beng)(beng)(beng)(beng)(beng)配合使(shi)用(yong)，如(ru)(ru)果没(mei)有达到(dao)一定(ding)的(de)(de)(de)(de)(de)(de)真空(kong)(kong)(kong)度，罗(luo)茨(ci)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)(fu)(fu)(fu)荷，马上(shang)跳(tiao)(tiao)闸(zha)(zha)。再者就(jiu)是(shi)(shi)基本(ben)的(de)(de)(de)(de)(de)(de)问(wen)(wen)题(ti)了比如(ru)(ru)被抽系统管路(lu)中是(shi)(shi)否(fou)(fou)(fou)有杂物(wu)，焊渣，小颗(ke)粒(li)进(jin)入(ru)(ru)到(dao)泵(beng)(beng)(beng)(beng)(beng)腔，然后就(jiu)是(shi)(shi)真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油了，罗(luo)茨(ci)水环真空(kong)(kong)(kong)机(ji)(ji)组如(ru)(ru)果没(mei)有按照相(xiang)应(ying)(ying)的(de)(de)(de)(de)(de)(de)启停(ting)顺(shun)序或(huo)是(shi)(shi)自动断电(dian)(dian)的(de)(de)(de)(de)(de)(de)情况下水环泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)工(gong)作(zuo)(zuo)(zuo)液会(hui)(hui)(hui)受(shou)负(fu)(fu)(fu)(fu)压的(de)(de)(de)(de)(de)(de)影响返到(dao)罗(luo)茨(ci)泵(beng)(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)(beng)腔内(nei)，破坏了真空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油的(de)(de)(de)(de)(de)(de)性能，从(cong)(cong)而(er)导致(zhi)罗(luo)茨(ci)泵(beng)(beng)(beng)(beng)(beng)超(chao)(chao)(chao)负(fu)(fu)(fu)(fu)荷工(gong)作(zuo)(zuo)(zuo)，超(chao)(chao)(chao)过(guo)(guo)(guo)额定(ding)电(dian)(dian)流而(er)跳(tiao)(tiao)闸(zha)(zha)。
