真空泵(beng)在工(gong)(gong)作(zuo)中如果跳了(le)闸，会使我们的工(gong)(gong)作(zuo)中断(duan)，浪费了(le)时间，那真空泵(beng)跳闸的原因是什(shen)么?应(ying)该如何(he)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.真空泵电(dian)(dian)(dian)(dian)机(ji)接在两相电(dian)(dian)(dian)(dian)源(yuan)(yuan)上(shang)，未启用三(san)(san)相电(dian)(dian)(dian)(dian)源(yuan)(yuan)，可接通(tong)(tong)真空泵三(san)(san)相电(dian)(dian)(dian)(dian)源(yuan)(yuan)即可。开(kai)机(ji)前(qian)可认真核对产品规格型号，功率大(da)小电(dian)(dian)(dian)(dian)压电(dian)(dian)(dian)(dian)流(liu)等情况(kuang)。或清相关的专业人士(shi)来接通(tong)(tong)电(dian)(dian)(dian)(dian)源(yuan)(yuan)。

3.电(dian)(dian)机(ji)(ji)(ji)(ji)超负(fu)荷(he)工(gong)作(zuo)(zuo)。真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)电(dian)(dian)机(ji)(ji)(ji)(ji)超负(fu)荷(he)工(gong)作(zuo)(zuo)，这(zhei)个(ge)(ge)时(shi)(shi)(shi)候电(dian)(dian)机(ji)(ji)(ji)(ji)的(de)电(dian)(dian)流(liu)肯定(ding)会(hui)(hui)过(guo)(guo)(guo)高，如(ru)超过(guo)(guo)(guo)电(dian)(dian)控(kong)箱或(huo)继点保护器设置(zhi)的(de)电(dian)(dian)流(liu)时(shi)(shi)(shi)，真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)会(hui)(hui)自行跳闸(zha)(zha)，此时(shi)(shi)(shi)为(wei)(wei)(wei)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)的(de)正常(chang)现象，可(ke)调高电(dian)(dian)流(liu)保护上限来解(jie)决跳闸(zha)(zha)现象。但(dan)是(shi)(shi)(shi)要(yao)(yao)考虑(lv)(lv)电(dian)(dian)机(ji)(ji)(ji)(ji)额定(ding)电(dian)(dian)流(liu)的(de)大小，如(ru)此时(shi)(shi)(shi)实际电(dian)(dian)流(liu)超过(guo)(guo)(guo)电(dian)(dian)机(ji)(ji)(ji)(ji)额定(ding)电(dian)(dian)流(liu)，那么(me)这(zhei)个(ge)(ge)方(fang)法(fa)就(jiu)不能用了。这(zhei)时(shi)(shi)(shi)要(yao)(yao)赶紧找出电(dian)(dian)机(ji)(ji)(ji)(ji)过(guo)(guo)(guo)载(zai)的(de)原因(yin)解(jie)决问(wen)(wen)(wen)题。例如(ru)水环式(shi)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)超电(dian)(dian)流(liu)就(jiu)要(yao)(yao)考虑(lv)(lv)是(shi)(shi)(shi)否(fou)(fou)有异物(wu)进(jin)(jin)入了泵(beng)腔(qiang)(qiang)内，导致电(dian)(dian)机(ji)(ji)(ji)(ji)超负(fu)荷(he)的(de)工(gong)作(zuo)(zuo)，还有工(gong)作(zuo)(zuo)液流(liu)量(liang)会(hui)(hui)不会(hui)(hui)过(guo)(guo)(guo)大，可(ke)相应(ying)调节。排气(qi)口是(shi)(shi)(shi)否(fou)(fou)压(ya)力过(guo)(guo)(guo)大，排气(qi)管路是(shi)(shi)(shi)否(fou)(fou)受阻，是(shi)(shi)(shi)否(fou)(fou)过(guo)(guo)(guo)高，过(guo)(guo)(guo)细等。而(er)旋片(pian)(pian)式(shi)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)没有工(gong)作(zuo)(zuo)液，可(ke)以不考虑(lv)(lv)以上问(wen)(wen)(wen)题。但(dan)旋片(pian)(pian)式(shi)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)需要(yao)(yao)加油，此时(shi)(shi)(shi)要(yao)(yao)考虑(lv)(lv)泵(beng)腔(qiang)(qiang)内的(de)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)油是(shi)(shi)(shi)否(fou)(fou)乳化变，或(huo)有杂物(wu)从进(jin)(jin)气(qi)口中进(jin)(jin)入。另外重(zhong)要(yao)(yao)的(de)要(yao)(yao)检查进(jin)(jin)气(qi)管路是(shi)(shi)(shi)否(fou)(fou)存在(zai)泄漏，因(yin)为(wei)(wei)(wei)旋片(pian)(pian)式(shi)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)适应(ying)抽密封的(de)系(xi)统，通大气(qi)使用会(hui)(hui)导致电(dian)(dian)机(ji)(ji)(ji)(ji)超负(fu)荷(he)而(er)跳闸(zha)(zha)。如(ru)果(guo)是(shi)(shi)(shi)罗茨(ci)(ci)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)或(huo)真(zhen)(zhen)(zhen)空(kong)(kong)机(ji)(ji)(ji)(ji)组(zu)的(de)话，问(wen)(wen)(wen)题就(jiu)相对(dui)简单明了，因(yin)为(wei)(wei)(wei)大家(jia)都知道(dao)罗茨(ci)(ci)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)是(shi)(shi)(shi)增(zeng)压(ya)泵(beng)不能单独(du)使用，需要(yao)(yao)前级泵(beng)配合使用，如(ru)果(guo)没有达到(dao)一定(ding)的(de)真(zhen)(zhen)(zhen)空(kong)(kong)度(du)，罗茨(ci)(ci)泵(beng)启动后电(dian)(dian)机(ji)(ji)(ji)(ji)会(hui)(hui)超负(fu)荷(he)，马上跳闸(zha)(zha)。再(zai)者就(jiu)是(shi)(shi)(shi)基本的(de)问(wen)(wen)(wen)题了比如(ru)被(bei)抽系(xi)统管路中是(shi)(shi)(shi)否(fou)(fou)有杂物(wu)，焊渣(zha)，小颗粒(li)进(jin)(jin)入到(dao)泵(beng)腔(qiang)(qiang)，然后就(jiu)是(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)油了，罗茨(ci)(ci)水环真(zhen)(zhen)(zhen)空(kong)(kong)机(ji)(ji)(ji)(ji)组(zu)如(ru)果(guo)没有按(an)照相应(ying)的(de)启停顺序或(huo)是(shi)(shi)(shi)自动断电(dian)(dian)的(de)情况下(xia)水环泵(beng)的(de)工(gong)作(zuo)(zuo)液会(hui)(hui)受负(fu)压(ya)的(de)影响(xiang)返(fan)到(dao)罗茨(ci)(ci)泵(beng)泵(beng)腔(qiang)(qiang)内，破坏了真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)油的(de)性能，从而(er)导致罗茨(ci)(ci)泵(beng)超负(fu)荷(he)工(gong)作(zuo)(zuo)，超过(guo)(guo)(guo)额定(ding)电(dian)(dian)流(liu)而(er)跳闸(zha)(zha)。
