大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)在使用(yong)(yong)一(yi)段时(shi)(shi)(shi)间后(hou)(hou)运(yun)转(zhuan)速度变慢(man)了(le)是什么原因呢?又(you)(you)或(huo)者(zhe)大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)在使用(yong)(yong)的(de)(de)过程中(zhong)突(tu)然变慢(man)了(le)怎么办?是什么原因导致这些问(wen)(wen)题(ti)发(fa)生呢?随(sui)子(zi)昂电(dian)(dian)(dian)机(ji)(ji)(ji)维修小编一(yi)起去了(le)解一(yi)下吧(ba)。机(ji)(ji)(ji)械故障是件(jian)让(rang)使用(yong)(yong)人(ren)(ren)防(fang)不胜防(fang)的(de)(de)工作(zuo),尤其是大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)故障,大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)运(yun)转(zhuan)慢(man)的(de)(de)原因经常(chang)有(you)(you)人(ren)(ren)问(wen)(wen)-电(dian)(dian)(dian)动车大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)如何(he)保养:电(dian)(dian)(dian)瓶(ping)车在行驶后(hou)(hou)停车时(shi)(shi)(shi),大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)启(qi)(qi)(qi)动不稳(wen)定,有(you)(you)时(shi)(shi)(shi)候(hou)正常(chang),有(you)(you)时(shi)(shi)(shi)候(hou)启(qi)(qi)(qi)动不起来(lai),踢打(da)或(huo)乱拍(pai)过后(hou)(hou),又(you)(you)会动转(zhuan),下次稍停车后(hou)(hou),又(you)(you)会又(you)(you)停下来(lai)几分(fen)钟无(wu)法启(qi)(qi)(qi)动,或(huo)启(qi)(qi)(qi)动时(shi)(shi)(shi),大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)转(zhuan)速很(hen)慢(man),着(zhe)实让(rang)人(ren)(ren)头疼,本文来(lai)分(fen)析大(da)(da)(da)(da)型(xing)(xing)电(dian)(dian)(dian)机(ji)(ji)(ji)运(yun)转(zhuan)慢(man)的(de)(de)原因。
大型(xing)(xing)(xing)电(dian)(dian)机(ji)(ji)运转慢的(de)故障原(yuan)因(yin)分析(xi)及(ji)处理(li)方法:大型(xing)(xing)(xing)电(dian)(dian)机(ji)(ji)修理(li)介绍,负载缺相(xiang)或偏(pian)相(xiang)(某一(yi)相(xiang)电(dian)(dian)压很低)是引(yin)起热(re)继(ji)电(dian)(dian)器(qi)动作的(de)主(zhu)要原(yuan)因(yin),而热(re)继(ji)电(dian)(dian)器(qi)是大型(xing)(xing)(xing)电(dian)(dian)机(ji)(ji)工作的(de)动力(li)源泉。由此得出大型(xing)(xing)(xing)电(dian)(dian)机(ji)(ji)运转慢的(de)原(yuan)因(yin)其实就(jiu)是热(re)继(ji)电(dian)(dian)器(qi)的(de)不正(zheng)常工作。所以我(wo)们(men)要对热(re)继(ji)电(dian)(dian)器(qi)进行(xing)检(jian)测(ce)、维修。日常最常见(jian)的(de)就(jiu)是直接检(jian)测(ce)法,关(guan)闭机(ji)(ji)器(qi),依据从(cong)(cong)后到前的(de)原(yuan)则,对每(mei)一(yi)个器(qi)件进行(xing)测(ce)量判(pan)断,从(cong)(cong)大型(xing)(xing)(xing)电(dian)(dian)机(ji)(ji)一(yi)直查到用户(hu)电(dian)(dian)源闸刀保险丝,将可能引(yin)起缺相(xiang)或接触(chu)不良的(de)控制器(qi)件更换或拧(ning)紧。
分析大型电机运转慢的原因最为常见的是:
1、热继电器与接触(chu)器连接部分接触(chu)不良。
2、交流接触(chu)器触(chu)点(dian)(dian)氧化(hua)、接触(chu)不良或(huo)触(chu)点(dian)(dian)烧坏(huai)。
3、各器件(jian)连接导线(xian)接触不(bu)良(liang),特别(bie)是电源开关和大(da)型电机本身的(de)接线(xian)。
4、用户(hu)闸刀保(bao)险丝(si)接触不(bu)良或进线端(duan)子接线松动。
5、热继电(dian)(dian)器保护(hu)电(dian)(dian)流(liu)调整的过低,特(te)别要(yao)注意夏(xia)天要(yao)将热继电(dian)(dian)器的整定(ding)电(dian)(dian)流(liu)适当调高(gao)一(yi)点(dian),一(yi)般是4.5——5安培。
6、热(re)继电(dian)器使(shi)用(yong)时(shi)间过长,本身内部的控制(zhi)锁定机构(gou)老化。
分析(xi)大型(xing)电机运转慢的(de)原(yuan)因后,我们日(ri)常针(zhen)对大型(xing)电机走走停(ting)(ting)停(ting)(ting),就要重(zhong)视起来,最好把大型(xing)电机拿(na)到维修铺去检测或修理(li)下,因为大型(xing)电机这种故障如不及时发现处理(li),时间一长,很容易烧坏大型(xing)电机和控制(zhi)系统的(de)器件。那样损失(shi)就会(hui)更大了。
