解决起重机制动器故障的方式

来源:http://impnow.com/news/168.html添加时间:2015-02-09

    起重机制动器是保障设备安全的一个重要部位,一旦出现故障后果将非常严重,下面就为大家讲解起重机制动器打不开的原因与解决方案。

    (1)主弹(dan)簧张力(li)过大、电磁(ci)铁(tie)磁(ci)拉力(li)小于主弹(dan)簧的张力(li),故打不开闸。重(zhong)新调整制动器(qi),使主弹(dan)簧张力(li)减小即可。

    (2)起重机(ji)制动器杠杆传动系统有卡住现象,松闸力在(zai)传递中受(shou)阻,故打不开侧。检(jian)查传动系统,消除卡塞现象即可解决。

    (3)起(qi)重机制(zhi)(zhi)动(dong)器制(zhi)(zhi)动(dong)螺(luo)杆弯曲(qu),螺(luo)杆头顶碰不到磁铁动(dong)铁心,故(gu)无法推(tui)开制(zhi)(zhi)动(dong)闸瓦。拆开制(zhi)(zhi)动(dong)器,取下螺(luo)杆将其(qi)调直或(huo)更(geng)换(huan)螺(luo)杆即可(ke)。

    (4)制(zhi)动(dong)瓦衬胶黏在有污垢的制(zhi)动(dong)轮(lun)工(gong)作面上。清除制(zhi)动(dong)轮(lun)表面上的污垢即(ji)可解决。

    (5)电磁铁线(xian)(xian)(xian)圈(quan)被(bei)烧毁或(huo)其接(jie)线(xian)(xian)(xian)折断、制(zhi)动电磁铁无磁拉力(li)所致(zhi)。更换(huan)制(zhi)动线(xian)(xian)(xian)圈(quan)或(huo)接(jie)通线(xian)(xian)(xian)圈(quan)接(jie)线(xian)(xian)(xian)即可。

    (6)液力(li)推(tui)动(dong)器的叶(ye)轮卡(ka)住。清(qing)除叶(ye)轮卡(ka)塞故(gu)障即(ji)可(ke)。

    (7)线(xian)(xian)路电(dian)(dian)压(ya)(ya)(ya)降过大,导(dao)致制动电(dian)(dian)磁铁线(xian)(xian)圈电(dian)(dian)压(ya)(ya)(ya)低(di)于额定电(dian)(dian)压(ya)(ya)(ya)的80%、磁铁磁拉力小于主弹簧的张力,故打不开闸。清除电(dian)(dian)压(ya)(ya)(ya)降的原因,恢(hui)复正常电(dian)(dian)压(ya)(ya)(ya)值即(ji)可解决。
