真空泵(beng)在工(gong)作中如果跳了闸，会使(shi)我们的工(gong)作中断，浪费了时间，那真空泵(beng)跳闸的原因是什(shen)么?应该如何解(jie)决(jue)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.真空泵电(dian)(dian)机接(jie)在两(liang)相(xiang)电(dian)(dian)源上，未启(qi)用三(san)相(xiang)电(dian)(dian)源，可接(jie)通真空泵三(san)相(xiang)电(dian)(dian)源即可。开机前可认真核对产(chan)品规格型号，功率大(da)小(xiao)电(dian)(dian)压(ya)电(dian)(dian)流等(deng)情况(kuang)。或清相(xiang)关的专业人士来接(jie)通电(dian)(dian)源。

3.电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷工(gong)作(zuo)(zuo)。真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷工(gong)作(zuo)(zuo)，这个时候电(dian)(dian)(dian)机(ji)(ji)的(de)(de)(de)电(dian)(dian)(dian)流(liu)肯(ken)定(ding)(ding)(ding)会(hui)(hui)过(guo)(guo)高，如(ru)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)控箱或(huo)继点保护器(qi)设置(zhi)的(de)(de)(de)电(dian)(dian)(dian)流(liu)时，真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)会(hui)(hui)自(zi)行跳(tiao)闸(zha)，此时为(wei)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)正常现象(xiang)，可(ke)调高电(dian)(dian)(dian)流(liu)保护上(shang)(shang)限来(lai)解决(jue)跳(tiao)闸(zha)现象(xiang)。但是(shi)(shi)(shi)(shi)要(yao)(yao)考(kao)虑(lv)电(dian)(dian)(dian)机(ji)(ji)额定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)的(de)(de)(de)大小(xiao)，如(ru)此时实际电(dian)(dian)(dian)流(liu)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)机(ji)(ji)额定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)，那么(me)这个方法(fa)就不能(neng)用(yong)了(le)(le)。这时要(yao)(yao)赶紧找出(chu)电(dian)(dian)(dian)机(ji)(ji)过(guo)(guo)载(zai)的(de)(de)(de)原(yuan)因解决(jue)问(wen)题(ti)。例如(ru)水(shui)(shui)环式真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)超(chao)(chao)(chao)电(dian)(dian)(dian)流(liu)就要(yao)(yao)考(kao)虑(lv)是(shi)(shi)(shi)(shi)否(fou)有(you)异物进(jin)(jin)入了(le)(le)泵(beng)(beng)(beng)腔(qiang)内(nei)，导致电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷的(de)(de)(de)工(gong)作(zuo)(zuo)，还有(you)工(gong)作(zuo)(zuo)液流(liu)量会(hui)(hui)不会(hui)(hui)过(guo)(guo)大，可(ke)相应调节。排气口是(shi)(shi)(shi)(shi)否(fou)压(ya)(ya)力过(guo)(guo)大，排气管路是(shi)(shi)(shi)(shi)否(fou)受阻，是(shi)(shi)(shi)(shi)否(fou)过(guo)(guo)高，过(guo)(guo)细(xi)等。而旋片(pian)式真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)没(mei)(mei)有(you)工(gong)作(zuo)(zuo)液，可(ke)以(yi)不考(kao)虑(lv)以(yi)上(shang)(shang)问(wen)题(ti)。但旋片(pian)式真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)需要(yao)(yao)加(jia)油，此时要(yao)(yao)考(kao)虑(lv)泵(beng)(beng)(beng)腔(qiang)内(nei)的(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油是(shi)(shi)(shi)(shi)否(fou)乳化变(bian)，或(huo)有(you)杂物从进(jin)(jin)气口中进(jin)(jin)入。另外重要(yao)(yao)的(de)(de)(de)要(yao)(yao)检(jian)查进(jin)(jin)气管路是(shi)(shi)(shi)(shi)否(fou)存在(zai)泄漏，因为(wei)旋片(pian)式真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)适应抽密封的(de)(de)(de)系(xi)(xi)统(tong)，通大气使(shi)用(yong)会(hui)(hui)导致电(dian)(dian)(dian)机(ji)(ji)超(chao)(chao)(chao)负荷而跳(tiao)闸(zha)。如(ru)果是(shi)(shi)(shi)(shi)罗(luo)(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)或(huo)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)(ji)组的(de)(de)(de)话，问(wen)题(ti)就相对简单(dan)明了(le)(le)，因为(wei)大家都(dou)知(zhi)道(dao)罗(luo)(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)是(shi)(shi)(shi)(shi)增(zeng)压(ya)(ya)泵(beng)(beng)(beng)不能(neng)单(dan)独(du)使(shi)用(yong)，需要(yao)(yao)前(qian)级泵(beng)(beng)(beng)配合(he)使(shi)用(yong)，如(ru)果没(mei)(mei)有(you)达(da)到一定(ding)(ding)(ding)的(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度，罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)启动后电(dian)(dian)(dian)机(ji)(ji)会(hui)(hui)超(chao)(chao)(chao)负荷，马上(shang)(shang)跳(tiao)闸(zha)。再者就是(shi)(shi)(shi)(shi)基本(ben)的(de)(de)(de)问(wen)题(ti)了(le)(le)比(bi)如(ru)被抽系(xi)(xi)统(tong)管路中是(shi)(shi)(shi)(shi)否(fou)有(you)杂物，焊渣，小(xiao)颗粒(li)进(jin)(jin)入到泵(beng)(beng)(beng)腔(qiang)，然后就是(shi)(shi)(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油了(le)(le)，罗(luo)(luo)茨(ci)水(shui)(shui)环真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)(ji)组如(ru)果没(mei)(mei)有(you)按照相应的(de)(de)(de)启停顺序或(huo)是(shi)(shi)(shi)(shi)自(zi)动断电(dian)(dian)(dian)的(de)(de)(de)情况下水(shui)(shui)环泵(beng)(beng)(beng)的(de)(de)(de)工(gong)作(zuo)(zuo)液会(hui)(hui)受负压(ya)(ya)的(de)(de)(de)影响(xiang)返到罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)泵(beng)(beng)(beng)腔(qiang)内(nei)，破坏了(le)(le)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油的(de)(de)(de)性能(neng)，从而导致罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)超(chao)(chao)(chao)负荷工(gong)作(zuo)(zuo)，超(chao)(chao)(chao)过(guo)(guo)额定(ding)(ding)(ding)电(dian)(dian)(dian)流(liu)而跳(tiao)闸(zha)。
