真空泵(beng)在工(gong)作中如(ru)果跳了(le)闸，会使我们的(de)工(gong)作中断，浪费了(le)时间(jian)，那真空泵(beng)跳闸的(de)原(yuan)因是什么?应该(gai)如(ru)何解(jie)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)空泵(beng)电(dian)(dian)(dian)机接(jie)在两(liang)相(xiang)电(dian)(dian)(dian)源(yuan)上(shang)，未启(qi)用三相(xiang)电(dian)(dian)(dian)源(yuan)，可(ke)接(jie)通真(zhen)空泵(beng)三相(xiang)电(dian)(dian)(dian)源(yuan)即可(ke)。开机前可(ke)认(ren)真(zhen)核对(dui)产品规格型号，功率大(da)小电(dian)(dian)(dian)压电(dian)(dian)(dian)流等情况。或清相(xiang)关的专业(ye)人(ren)士来(lai)接(jie)通电(dian)(dian)(dian)源(yuan)。

3.电(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)荷(he)工(gong)作(zuo)(zuo)。真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)电(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)荷(he)工(gong)作(zuo)(zuo)，这(zhei)(zhei)个时候电(dian)(dian)(dian)(dian)机(ji)的(de)(de)电(dian)(dian)(dian)(dian)流(liu)(liu)肯定会(hui)(hui)过(guo)高，如超(chao)(chao)(chao)过(guo)电(dian)(dian)(dian)(dian)控箱(xiang)或继点保护(hu)器(qi)设置(zhi)的(de)(de)电(dian)(dian)(dian)(dian)流(liu)(liu)时，真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)会(hui)(hui)自行(xing)跳(tiao)闸(zha)，此(ci)时为(wei)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)正常现象，可调(diao)高电(dian)(dian)(dian)(dian)流(liu)(liu)保护(hu)上(shang)(shang)限来解决跳(tiao)闸(zha)现象。但(dan)是(shi)(shi)(shi)要(yao)(yao)(yao)(yao)考(kao)虑电(dian)(dian)(dian)(dian)机(ji)额(e)定电(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)大(da)小，如此(ci)时实际电(dian)(dian)(dian)(dian)流(liu)(liu)超(chao)(chao)(chao)过(guo)电(dian)(dian)(dian)(dian)机(ji)额(e)定电(dian)(dian)(dian)(dian)流(liu)(liu)，那(nei)么这(zhei)(zhei)个方法就(jiu)不能用(yong)了(le)(le)。这(zhei)(zhei)时要(yao)(yao)(yao)(yao)赶紧找出电(dian)(dian)(dian)(dian)机(ji)过(guo)载的(de)(de)原因(yin)解决问(wen)题。例如水(shui)环(huan)式(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)超(chao)(chao)(chao)电(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)要(yao)(yao)(yao)(yao)考(kao)虑是(shi)(shi)(shi)否有(you)(you)异物进入了(le)(le)泵(beng)(beng)(beng)腔内(nei)，导致(zhi)电(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)荷(he)的(de)(de)工(gong)作(zuo)(zuo)，还(hai)有(you)(you)工(gong)作(zuo)(zuo)液流(liu)(liu)量(liang)会(hui)(hui)不会(hui)(hui)过(guo)大(da)，可相(xiang)应(ying)(ying)调(diao)节。排(pai)气(qi)口(kou)是(shi)(shi)(shi)否压力过(guo)大(da)，排(pai)气(qi)管(guan)路是(shi)(shi)(shi)否受阻(zu)，是(shi)(shi)(shi)否过(guo)高，过(guo)细等(deng)。而旋片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)没(mei)有(you)(you)工(gong)作(zuo)(zuo)液，可以不考(kao)虑以上(shang)(shang)问(wen)题。但(dan)旋片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)需要(yao)(yao)(yao)(yao)加油，此(ci)时要(yao)(yao)(yao)(yao)考(kao)虑泵(beng)(beng)(beng)腔内(nei)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油是(shi)(shi)(shi)否乳化变(bian)，或有(you)(you)杂物从(cong)进气(qi)口(kou)中(zhong)进入。另外重要(yao)(yao)(yao)(yao)的(de)(de)要(yao)(yao)(yao)(yao)检查(cha)进气(qi)管(guan)路是(shi)(shi)(shi)否存在(zai)泄(xie)漏(lou)，因(yin)为(wei)旋片(pian)式(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)适应(ying)(ying)抽(chou)密(mi)封的(de)(de)系统，通大(da)气(qi)使(shi)用(yong)会(hui)(hui)导致(zhi)电(dian)(dian)(dian)(dian)机(ji)超(chao)(chao)(chao)负(fu)荷(he)而跳(tiao)闸(zha)。如果(guo)是(shi)(shi)(shi)罗(luo)茨(ci)(ci)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)或真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)组(zu)的(de)(de)话(hua)，问(wen)题就(jiu)相(xiang)对简(jian)单明了(le)(le)，因(yin)为(wei)大(da)家都知道罗(luo)茨(ci)(ci)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)是(shi)(shi)(shi)增压泵(beng)(beng)(beng)不能单独使(shi)用(yong)，需要(yao)(yao)(yao)(yao)前级泵(beng)(beng)(beng)配(pei)合使(shi)用(yong)，如果(guo)没(mei)有(you)(you)达到(dao)一定的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度，罗(luo)茨(ci)(ci)泵(beng)(beng)(beng)启(qi)动后(hou)电(dian)(dian)(dian)(dian)机(ji)会(hui)(hui)超(chao)(chao)(chao)负(fu)荷(he)，马上(shang)(shang)跳(tiao)闸(zha)。再者(zhe)就(jiu)是(shi)(shi)(shi)基本的(de)(de)问(wen)题了(le)(le)比(bi)如被抽(chou)系统管(guan)路中(zhong)是(shi)(shi)(shi)否有(you)(you)杂物，焊渣(zha)，小颗粒进入到(dao)泵(beng)(beng)(beng)腔，然后(hou)就(jiu)是(shi)(shi)(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油了(le)(le)，罗(luo)茨(ci)(ci)水(shui)环(huan)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)机(ji)组(zu)如果(guo)没(mei)有(you)(you)按照相(xiang)应(ying)(ying)的(de)(de)启(qi)停顺序或是(shi)(shi)(shi)自动断电(dian)(dian)(dian)(dian)的(de)(de)情况下(xia)水(shui)环(huan)泵(beng)(beng)(beng)的(de)(de)工(gong)作(zuo)(zuo)液会(hui)(hui)受负(fu)压的(de)(de)影(ying)响返到(dao)罗(luo)茨(ci)(ci)泵(beng)(beng)(beng)泵(beng)(beng)(beng)腔内(nei)，破坏了(le)(le)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)油的(de)(de)性能，从(cong)而导致(zhi)罗(luo)茨(ci)(ci)泵(beng)(beng)(beng)超(chao)(chao)(chao)负(fu)荷(he)工(gong)作(zuo)(zuo)，超(chao)(chao)(chao)过(guo)额(e)定电(dian)(dian)(dian)(dian)流(liu)(liu)而跳(tiao)闸(zha)。
