真空泵(beng)在工作(zuo)中(zhong)如(ru)果跳了闸(zha)，会(hui)使(shi)我们(men)的(de)工作(zuo)中(zhong)断，浪费了时间，那(nei)真空泵(beng)跳闸(zha)的(de)原因是什么?应(ying)该如(ru)何解(jie)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(beng)电机接(jie)(jie)在两相电源(yuan)上，未启用(yong)三相电源(yuan)，可(ke)接(jie)(jie)通真空泵(beng)三相电源(yuan)即可(ke)。开机前(qian)可(ke)认真核(he)对(dui)产品规格型号，功(gong)率大小电压电流等(deng)情况。或清相关的专业人士来接(jie)(jie)通电源(yuan)。

3.电(dian)(dian)(dian)(dian)(dian)机超负(fu)荷工(gong)(gong)作(zuo)。真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)电(dian)(dian)(dian)(dian)(dian)机超负(fu)荷工(gong)(gong)作(zuo)，这个时(shi)候电(dian)(dian)(dian)(dian)(dian)机的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)流(liu)肯(ken)定(ding)(ding)会(hui)(hui)过(guo)高，如(ru)超过(guo)电(dian)(dian)(dian)(dian)(dian)控箱或(huo)继点(dian)保护(hu)器设(she)置(zhi)的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)流(liu)时(shi)，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)会(hui)(hui)自行(xing)跳闸(zha)(zha)，此时(shi)为真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)正(zheng)常(chang)现(xian)象，可调高电(dian)(dian)(dian)(dian)(dian)流(liu)保护(hu)上限来解决(jue)跳闸(zha)(zha)现(xian)象。但是(shi)(shi)(shi)要(yao)(yao)考(kao)虑(lv)电(dian)(dian)(dian)(dian)(dian)机额定(ding)(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)大(da)小，如(ru)此时(shi)实际电(dian)(dian)(dian)(dian)(dian)流(liu)超过(guo)电(dian)(dian)(dian)(dian)(dian)机额定(ding)(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)，那么这个方法就不能(neng)用(yong)了。这时(shi)要(yao)(yao)赶紧找出(chu)电(dian)(dian)(dian)(dian)(dian)机过(guo)载的(de)(de)(de)原因解决(jue)问题。例如(ru)水环(huan)式(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)超电(dian)(dian)(dian)(dian)(dian)流(liu)就要(yao)(yao)考(kao)虑(lv)是(shi)(shi)(shi)否(fou)(fou)(fou)有(you)异物进(jin)入了泵(beng)(beng)(beng)(beng)(beng)腔内(nei)，导(dao)(dao)致电(dian)(dian)(dian)(dian)(dian)机超负(fu)荷的(de)(de)(de)工(gong)(gong)作(zuo)，还有(you)工(gong)(gong)作(zuo)液(ye)流(liu)量会(hui)(hui)不会(hui)(hui)过(guo)大(da)，可相应(ying)调节。排气口(kou)是(shi)(shi)(shi)否(fou)(fou)(fou)压力过(guo)大(da)，排气管(guan)路(lu)(lu)是(shi)(shi)(shi)否(fou)(fou)(fou)受(shou)阻，是(shi)(shi)(shi)否(fou)(fou)(fou)过(guo)高，过(guo)细等。而(er)(er)旋片(pian)(pian)式(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)没(mei)有(you)工(gong)(gong)作(zuo)液(ye)，可以不考(kao)虑(lv)以上问题。但旋片(pian)(pian)式(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)需(xu)要(yao)(yao)加油(you)，此时(shi)要(yao)(yao)考(kao)虑(lv)泵(beng)(beng)(beng)(beng)(beng)腔内(nei)的(de)(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油(you)是(shi)(shi)(shi)否(fou)(fou)(fou)乳化变，或(huo)有(you)杂物从进(jin)气口(kou)中(zhong)进(jin)入。另外重要(yao)(yao)的(de)(de)(de)要(yao)(yao)检查进(jin)气管(guan)路(lu)(lu)是(shi)(shi)(shi)否(fou)(fou)(fou)存(cun)在泄漏，因为旋片(pian)(pian)式(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)适应(ying)抽密封的(de)(de)(de)系统，通(tong)大(da)气使(shi)用(yong)会(hui)(hui)导(dao)(dao)致电(dian)(dian)(dian)(dian)(dian)机超负(fu)荷而(er)(er)跳闸(zha)(zha)。如(ru)果是(shi)(shi)(shi)罗(luo)(luo)茨(ci)(ci)(ci)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)或(huo)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)机组(zu)的(de)(de)(de)话，问题就相对简单(dan)(dan)明了，因为大(da)家都知道(dao)罗(luo)(luo)茨(ci)(ci)(ci)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)是(shi)(shi)(shi)增(zeng)压泵(beng)(beng)(beng)(beng)(beng)不能(neng)单(dan)(dan)独使(shi)用(yong)，需(xu)要(yao)(yao)前级(ji)泵(beng)(beng)(beng)(beng)(beng)配合使(shi)用(yong)，如(ru)果没(mei)有(you)达(da)到一定(ding)(ding)的(de)(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)度(du)，罗(luo)(luo)茨(ci)(ci)(ci)泵(beng)(beng)(beng)(beng)(beng)启动(dong)后电(dian)(dian)(dian)(dian)(dian)机会(hui)(hui)超负(fu)荷，马上跳闸(zha)(zha)。再者就是(shi)(shi)(shi)基本的(de)(de)(de)问题了比如(ru)被(bei)抽系统管(guan)路(lu)(lu)中(zhong)是(shi)(shi)(shi)否(fou)(fou)(fou)有(you)杂物，焊渣，小颗粒进(jin)入到泵(beng)(beng)(beng)(beng)(beng)腔，然后就是(shi)(shi)(shi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油(you)了，罗(luo)(luo)茨(ci)(ci)(ci)水环(huan)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)机组(zu)如(ru)果没(mei)有(you)按照相应(ying)的(de)(de)(de)启停(ting)顺序或(huo)是(shi)(shi)(shi)自动(dong)断(duan)电(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)情况下水环(huan)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)工(gong)(gong)作(zuo)液(ye)会(hui)(hui)受(shou)负(fu)压的(de)(de)(de)影(ying)响返到罗(luo)(luo)茨(ci)(ci)(ci)泵(beng)(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)(beng)腔内(nei)，破坏了真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)油(you)的(de)(de)(de)性能(neng)，从而(er)(er)导(dao)(dao)致罗(luo)(luo)茨(ci)(ci)(ci)泵(beng)(beng)(beng)(beng)(beng)超负(fu)荷工(gong)(gong)作(zuo)，超过(guo)额定(ding)(ding)电(dian)(dian)(dian)(dian)(dian)流(liu)而(er)(er)跳闸(zha)(zha)。
