真空泵在工(gong)作(zuo)中(zhong)如果跳了(le)闸(zha)，会使我们的工(gong)作(zuo)中(zhong)断，浪费了(le)时间，那真空泵跳闸(zha)的原因是什么?应(ying)该如何解决呢?

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)空泵电机接在两(liang)相电源(yuan)(yuan)上，未启用三相电源(yuan)(yuan)，可(ke)(ke)(ke)接通(tong)真(zhen)空泵三相电源(yuan)(yuan)即(ji)可(ke)(ke)(ke)。开机前可(ke)(ke)(ke)认真(zhen)核对产品规格型号，功率大小(xiao)电压电流等情况。或清相关的专(zhuan)业人士来(lai)接通(tong)电源(yuan)(yuan)。

3.电(dian)(dian)(dian)机(ji)超(chao)(chao)负荷(he)工(gong)作(zuo)。真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)电(dian)(dian)(dian)机(ji)超(chao)(chao)负荷(he)工(gong)作(zuo)，这(zhei)个(ge)时(shi)(shi)候电(dian)(dian)(dian)机(ji)的(de)电(dian)(dian)(dian)流肯定会(hui)(hui)过(guo)(guo)(guo)(guo)高(gao)，如(ru)超(chao)(chao)过(guo)(guo)(guo)(guo)电(dian)(dian)(dian)控箱或(huo)继点保护器(qi)设置的(de)电(dian)(dian)(dian)流时(shi)(shi)，真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)会(hui)(hui)自(zi)行跳(tiao)(tiao)(tiao)闸，此(ci)时(shi)(shi)为真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)的(de)正常现象(xiang)(xiang)，可(ke)调高(gao)电(dian)(dian)(dian)流保护上限来(lai)解(jie)决跳(tiao)(tiao)(tiao)闸现象(xiang)(xiang)。但(dan)(dan)是(shi)(shi)(shi)要(yao)考(kao)虑电(dian)(dian)(dian)机(ji)额(e)定电(dian)(dian)(dian)流的(de)大(da)(da)小，如(ru)此(ci)时(shi)(shi)实际电(dian)(dian)(dian)流超(chao)(chao)过(guo)(guo)(guo)(guo)电(dian)(dian)(dian)机(ji)额(e)定电(dian)(dian)(dian)流，那么这(zhei)个(ge)方法就不能(neng)(neng)用(yong)了(le)(le)。这(zhei)时(shi)(shi)要(yao)赶(gan)紧(jin)找出电(dian)(dian)(dian)机(ji)过(guo)(guo)(guo)(guo)载的(de)原因(yin)解(jie)决问(wen)题(ti)。例(li)如(ru)水(shui)(shui)环式真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)超(chao)(chao)电(dian)(dian)(dian)流就要(yao)考(kao)虑是(shi)(shi)(shi)否(fou)有(you)(you)(you)异物进(jin)入(ru)了(le)(le)泵(beng)(beng)(beng)(beng)腔内，导(dao)致电(dian)(dian)(dian)机(ji)超(chao)(chao)负荷(he)的(de)工(gong)作(zuo)，还有(you)(you)(you)工(gong)作(zuo)液流量(liang)会(hui)(hui)不会(hui)(hui)过(guo)(guo)(guo)(guo)大(da)(da)，可(ke)相(xiang)应调节。排气(qi)口(kou)是(shi)(shi)(shi)否(fou)压力过(guo)(guo)(guo)(guo)大(da)(da)，排气(qi)管(guan)(guan)路(lu)是(shi)(shi)(shi)否(fou)受阻，是(shi)(shi)(shi)否(fou)过(guo)(guo)(guo)(guo)高(gao)，过(guo)(guo)(guo)(guo)细等(deng)。而(er)旋片式真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)没有(you)(you)(you)工(gong)作(zuo)液，可(ke)以不考(kao)虑以上问(wen)题(ti)。但(dan)(dan)旋片式真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)需要(yao)加油(you)，此(ci)时(shi)(shi)要(yao)考(kao)虑泵(beng)(beng)(beng)(beng)腔内的(de)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)油(you)是(shi)(shi)(shi)否(fou)乳化(hua)变(bian)，或(huo)有(you)(you)(you)杂物从(cong)进(jin)气(qi)口(kou)中进(jin)入(ru)。另外(wai)重要(yao)的(de)要(yao)检查(cha)进(jin)气(qi)管(guan)(guan)路(lu)是(shi)(shi)(shi)否(fou)存在(zai)泄(xie)漏，因(yin)为旋片式真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)适应抽密封的(de)系统，通大(da)(da)气(qi)使(shi)(shi)(shi)用(yong)会(hui)(hui)导(dao)致电(dian)(dian)(dian)机(ji)超(chao)(chao)负荷(he)而(er)跳(tiao)(tiao)(tiao)闸。如(ru)果(guo)是(shi)(shi)(shi)罗茨(ci)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)或(huo)真(zhen)(zhen)(zhen)空(kong)机(ji)组的(de)话，问(wen)题(ti)就相(xiang)对简单明了(le)(le)，因(yin)为大(da)(da)家(jia)都(dou)知(zhi)道罗茨(ci)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)是(shi)(shi)(shi)增(zeng)压泵(beng)(beng)(beng)(beng)不能(neng)(neng)单独使(shi)(shi)(shi)用(yong)，需要(yao)前级(ji)泵(beng)(beng)(beng)(beng)配合使(shi)(shi)(shi)用(yong)，如(ru)果(guo)没有(you)(you)(you)达到一(yi)定的(de)真(zhen)(zhen)(zhen)空(kong)度，罗茨(ci)泵(beng)(beng)(beng)(beng)启动后电(dian)(dian)(dian)机(ji)会(hui)(hui)超(chao)(chao)负荷(he)，马上跳(tiao)(tiao)(tiao)闸。再(zai)者就是(shi)(shi)(shi)基本的(de)问(wen)题(ti)了(le)(le)比如(ru)被抽系统管(guan)(guan)路(lu)中是(shi)(shi)(shi)否(fou)有(you)(you)(you)杂物，焊渣，小颗粒进(jin)入(ru)到泵(beng)(beng)(beng)(beng)腔，然后就是(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)油(you)了(le)(le)，罗茨(ci)水(shui)(shui)环真(zhen)(zhen)(zhen)空(kong)机(ji)组如(ru)果(guo)没有(you)(you)(you)按照相(xiang)应的(de)启停顺序(xu)或(huo)是(shi)(shi)(shi)自(zi)动断电(dian)(dian)(dian)的(de)情况下水(shui)(shui)环泵(beng)(beng)(beng)(beng)的(de)工(gong)作(zuo)液会(hui)(hui)受负压的(de)影响(xiang)返到罗茨(ci)泵(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)腔内，破坏(huai)了(le)(le)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)油(you)的(de)性能(neng)(neng)，从(cong)而(er)导(dao)致罗茨(ci)泵(beng)(beng)(beng)(beng)超(chao)(chao)负荷(he)工(gong)作(zuo)，超(chao)(chao)过(guo)(guo)(guo)(guo)额(e)定电(dian)(dian)(dian)流而(er)跳(tiao)(tiao)(tiao)闸。
