真空泵在工作中(zhong)如果跳了闸，会使(shi)我们的(de)工作中(zhong)断，浪费了时间，那真空泵跳闸的(de)原(yuan)因是(shi)什么?应该如何解决(jue)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)空泵电(dian)机(ji)接(jie)在两(liang)相电(dian)源上，未启用三(san)相电(dian)源，可接(jie)通真(zhen)(zhen)空泵三(san)相电(dian)源即可。开(kai)机(ji)前可认(ren)真(zhen)(zhen)核对(dui)产品规(gui)格(ge)型号，功率大小电(dian)压电(dian)流等情况。或清相关的专业(ye)人士(shi)来(lai)接(jie)通电(dian)源。

3.电(dian)(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)工(gong)作(zuo)(zuo)。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)电(dian)(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)工(gong)作(zuo)(zuo)，这(zhei)个时候电(dian)(dian)(dian)(dian)(dian)机(ji)的(de)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)肯定(ding)会(hui)过(guo)(guo)高(gao)，如(ru)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)(dian)(dian)控箱或继点保护器设置的(de)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)时，真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)会(hui)自(zi)行跳(tiao)(tiao)闸(zha)(zha)(zha)，此时为(wei)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)正常现象，可(ke)调(diao)高(gao)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)保护上(shang)限来解决跳(tiao)(tiao)闸(zha)(zha)(zha)现象。但是要(yao)考(kao)虑(lv)电(dian)(dian)(dian)(dian)(dian)机(ji)额(e)定(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)大(da)(da)小，如(ru)此时实际(ji)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)超(chao)(chao)(chao)过(guo)(guo)电(dian)(dian)(dian)(dian)(dian)机(ji)额(e)定(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，那么这(zhei)个方法就(jiu)(jiu)不(bu)能用(yong)(yong)了(le)(le)。这(zhei)时要(yao)赶紧(jin)找出电(dian)(dian)(dian)(dian)(dian)机(ji)过(guo)(guo)载的(de)原因解决问(wen)题。例如(ru)水(shui)(shui)环式(shi)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)超(chao)(chao)(chao)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)(jiu)要(yao)考(kao)虑(lv)是否(fou)(fou)有(you)异物进入(ru)了(le)(le)泵(beng)(beng)(beng)腔内，导致(zhi)电(dian)(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)的(de)工(gong)作(zuo)(zuo)，还有(you)工(gong)作(zuo)(zuo)液流(liu)(liu)量会(hui)不(bu)会(hui)过(guo)(guo)大(da)(da)，可(ke)相应(ying)调(diao)节。排气口是否(fou)(fou)压力过(guo)(guo)大(da)(da)，排气管路是否(fou)(fou)受(shou)阻，是否(fou)(fou)过(guo)(guo)高(gao)，过(guo)(guo)细(xi)等。而旋(xuan)(xuan)片(pian)式(shi)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)没有(you)工(gong)作(zuo)(zuo)液，可(ke)以不(bu)考(kao)虑(lv)以上(shang)问(wen)题。但旋(xuan)(xuan)片(pian)式(shi)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)需(xu)要(yao)加油，此时要(yao)考(kao)虑(lv)泵(beng)(beng)(beng)腔内的(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)油是否(fou)(fou)乳化变，或有(you)杂物从进气口中进入(ru)。另外重(zhong)要(yao)的(de)要(yao)检查进气管路是否(fou)(fou)存在泄漏，因为(wei)旋(xuan)(xuan)片(pian)式(shi)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)适应(ying)抽密(mi)封的(de)系(xi)(xi)统，通大(da)(da)气使用(yong)(yong)会(hui)导致(zhi)电(dian)(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)而跳(tiao)(tiao)闸(zha)(zha)(zha)。如(ru)果(guo)是罗(luo)(luo)茨(ci)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)或真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)机(ji)组的(de)话(hua)，问(wen)题就(jiu)(jiu)相对(dui)简(jian)单明了(le)(le)，因为(wei)大(da)(da)家都知道罗(luo)(luo)茨(ci)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)是增压泵(beng)(beng)(beng)不(bu)能单独(du)使用(yong)(yong)，需(xu)要(yao)前级泵(beng)(beng)(beng)配合(he)使用(yong)(yong)，如(ru)果(guo)没有(you)达(da)到一定(ding)的(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度，罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)启动(dong)后电(dian)(dian)(dian)(dian)(dian)机(ji)会(hui)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)，马上(shang)跳(tiao)(tiao)闸(zha)(zha)(zha)。再(zai)者就(jiu)(jiu)是基本的(de)问(wen)题了(le)(le)比(bi)如(ru)被抽系(xi)(xi)统管路中是否(fou)(fou)有(you)杂物，焊(han)渣，小颗粒进入(ru)到泵(beng)(beng)(beng)腔，然后就(jiu)(jiu)是真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)油了(le)(le)，罗(luo)(luo)茨(ci)水(shui)(shui)环真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)机(ji)组如(ru)果(guo)没有(you)按(an)照相应(ying)的(de)启停(ting)顺序或是自(zi)动(dong)断(duan)电(dian)(dian)(dian)(dian)(dian)的(de)情况(kuang)下水(shui)(shui)环泵(beng)(beng)(beng)的(de)工(gong)作(zuo)(zuo)液会(hui)受(shou)负(fu)(fu)(fu)压的(de)影(ying)响返到罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)泵(beng)(beng)(beng)腔内，破坏了(le)(le)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)油的(de)性能，从而导致(zhi)罗(luo)(luo)茨(ci)泵(beng)(beng)(beng)超(chao)(chao)(chao)负(fu)(fu)(fu)荷(he)工(gong)作(zuo)(zuo)，超(chao)(chao)(chao)过(guo)(guo)额(e)定(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)(liu)而跳(tiao)(tiao)闸(zha)(zha)(zha)。
