真空泵(beng)在工作(zuo)中如(ru)果跳了闸(zha)，会使我们的工作(zuo)中断(duan)，浪费了时间，那真空泵(beng)跳闸(zha)的原因是什么(me)?应(ying)该如(ru)何(he)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)空(kong)(kong)泵(beng)电机接在两(liang)相(xiang)(xiang)(xiang)电源(yuan)上，未启用三相(xiang)(xiang)(xiang)电源(yuan)，可接通真(zhen)空(kong)(kong)泵(beng)三相(xiang)(xiang)(xiang)电源(yuan)即(ji)可。开机前可认(ren)真(zhen)核(he)对产(chan)品规格型号，功率大小电压电流等情况。或(huo)清相(xiang)(xiang)(xiang)关的专业(ye)人士来接通电源(yuan)。

3.电(dian)机(ji)超(chao)(chao)负(fu)(fu)荷(he)工(gong)(gong)(gong)(gong)作(zuo)。真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)电(dian)机(ji)超(chao)(chao)负(fu)(fu)荷(he)工(gong)(gong)(gong)(gong)作(zuo)，这(zhei)个(ge)时(shi)候电(dian)机(ji)的电(dian)流(liu)肯定(ding)(ding)会(hui)(hui)过(guo)(guo)高(gao)，如(ru)(ru)超(chao)(chao)过(guo)(guo)电(dian)控箱或继点(dian)保(bao)护(hu)器设置(zhi)的电(dian)流(liu)时(shi)，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)会(hui)(hui)自(zi)行跳(tiao)闸，此时(shi)为真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的正常现象，可(ke)(ke)调高(gao)电(dian)流(liu)保(bao)护(hu)上限来解决(jue)跳(tiao)闸现象。但是要(yao)(yao)考虑(lv)电(dian)机(ji)额(e)(e)定(ding)(ding)电(dian)流(liu)的大(da)小，如(ru)(ru)此时(shi)实际电(dian)流(liu)超(chao)(chao)过(guo)(guo)电(dian)机(ji)额(e)(e)定(ding)(ding)电(dian)流(liu)，那(nei)么这(zhei)个(ge)方法(fa)就(jiu)不能(neng)用了(le)(le)(le)(le)。这(zhei)时(shi)要(yao)(yao)赶紧找出(chu)电(dian)机(ji)过(guo)(guo)载(zai)的原因(yin)解决(jue)问(wen)(wen)题(ti)(ti)。例如(ru)(ru)水(shui)环式(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)超(chao)(chao)电(dian)流(liu)就(jiu)要(yao)(yao)考虑(lv)是否有(you)异物(wu)进(jin)(jin)入(ru)了(le)(le)(le)(le)泵(beng)(beng)(beng)腔内(nei)(nei)，导(dao)致(zhi)电(dian)机(ji)超(chao)(chao)负(fu)(fu)荷(he)的工(gong)(gong)(gong)(gong)作(zuo)，还有(you)工(gong)(gong)(gong)(gong)作(zuo)液流(liu)量(liang)会(hui)(hui)不会(hui)(hui)过(guo)(guo)大(da)，可(ke)(ke)相(xiang)应(ying)调节。排(pai)气(qi)口是否压(ya)力过(guo)(guo)大(da)，排(pai)气(qi)管路是否受阻，是否过(guo)(guo)高(gao)，过(guo)(guo)细等(deng)。而旋(xuan)片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)没(mei)有(you)工(gong)(gong)(gong)(gong)作(zuo)液，可(ke)(ke)以不考虑(lv)以上问(wen)(wen)题(ti)(ti)。但旋(xuan)片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)需要(yao)(yao)加油(you)，此时(shi)要(yao)(yao)考虑(lv)泵(beng)(beng)(beng)腔内(nei)(nei)的真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油(you)是否乳(ru)化变(bian)，或有(you)杂物(wu)从进(jin)(jin)气(qi)口中进(jin)(jin)入(ru)。另外重要(yao)(yao)的要(yao)(yao)检查进(jin)(jin)气(qi)管路是否存在泄(xie)漏，因(yin)为旋(xuan)片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)适(shi)应(ying)抽密封的系统，通大(da)气(qi)使(shi)用会(hui)(hui)导(dao)致(zhi)电(dian)机(ji)超(chao)(chao)负(fu)(fu)荷(he)而跳(tiao)闸。如(ru)(ru)果是罗茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)或真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)组的话(hua)，问(wen)(wen)题(ti)(ti)就(jiu)相(xiang)对简单(dan)明了(le)(le)(le)(le)，因(yin)为大(da)家都知道罗茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)是增(zeng)压(ya)泵(beng)(beng)(beng)不能(neng)单(dan)独(du)使(shi)用，需要(yao)(yao)前级(ji)泵(beng)(beng)(beng)配合使(shi)用，如(ru)(ru)果没(mei)有(you)达到一(yi)定(ding)(ding)的真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度，罗茨(ci)泵(beng)(beng)(beng)启动后(hou)电(dian)机(ji)会(hui)(hui)超(chao)(chao)负(fu)(fu)荷(he)，马上跳(tiao)闸。再者就(jiu)是基本(ben)的问(wen)(wen)题(ti)(ti)了(le)(le)(le)(le)比(bi)如(ru)(ru)被抽系统管路中是否有(you)杂物(wu)，焊渣，小颗粒进(jin)(jin)入(ru)到泵(beng)(beng)(beng)腔，然(ran)后(hou)就(jiu)是真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油(you)了(le)(le)(le)(le)，罗茨(ci)水(shui)环真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)组如(ru)(ru)果没(mei)有(you)按照相(xiang)应(ying)的启停顺序或是自(zi)动断电(dian)的情(qing)况下水(shui)环泵(beng)(beng)(beng)的工(gong)(gong)(gong)(gong)作(zuo)液会(hui)(hui)受负(fu)(fu)压(ya)的影响返到罗茨(ci)泵(beng)(beng)(beng)泵(beng)(beng)(beng)腔内(nei)(nei)，破坏了(le)(le)(le)(le)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油(you)的性能(neng)，从而导(dao)致(zhi)罗茨(ci)泵(beng)(beng)(beng)超(chao)(chao)负(fu)(fu)荷(he)工(gong)(gong)(gong)(gong)作(zuo)，超(chao)(chao)过(guo)(guo)额(e)(e)定(ding)(ding)电(dian)流(liu)而跳(tiao)闸。
