液压制动器的使用要求

来源:http://impnow.com/news/44.html添加时间:2015-01-15

    液压(ya)制(zhi)(zhi)动器(qi)是(shi)现在(zai)常(chang)用(yong)到(dao)的(de)刹车(che)装置,它(ta)的(de)组件(jian)有制(zhi)(zhi)架、制(zhi)(zhi)动件(jian)和操纵装置等(deng)。由于现在(zai)所用(yong)到(dao)的(de)液压(ya)制(zhi)(zhi)动器(qi)要求非常(chang)高,所以已经交由******工(gong)厂进(jin)行加工(gong)制(zhi)(zhi)造。那么在(zai)它(ta)的(de)使用(yong)过程(cheng)中有哪些要求呢?

    液压制动(dong)(dong)(dong)(dong)(dong)器在使用中(zhong),电液推(tui)杆(gan)的(de)电源一般与(yu)设备主(zhu)级动(dong)(dong)(dong)(dong)(dong)电动(dong)(dong)(dong)(dong)(dong)机的(de)电源并(bing)联,不另取线路,所以适合于380V三相交流电源与(yu)主(zhu)电动(dong)(dong)(dong)(dong)(dong)机同(tong)步启停.通电时,主(zhu)电动(dong)(dong)(dong)(dong)(dong)机启动(dong)(dong)(dong)(dong)(dong)运转(zhuan)(zhuan)(zhuan),同(tong)时制动(dong)(dong)(dong)(dong)(dong)器的(de)电动(dong)(dong)(dong)(dong)(dong)机带动(dong)(dong)(dong)(dong)(dong)叶(ye)轮(lun)转(zhuan)(zhuan)(zhuan)动(dong)(dong)(dong)(dong)(dong),将油从活塞(sai)上部吸(xi)到(dao)活塞(sai)下(xia)部,产生汕压推(tui)动(dong)(dong)(dong)(dong)(dong)活塞(sai)推(tui)杆(gan)迅(xun)速(su)上升,完成额定(ding)行程达到(dao)规(gui)定(ding)推(tui)力(li),制动(dong)(dong)(dong)(dong)(dong)器闸瓦打开,设备开始正常(chang)运转(zhuan)(zhuan)(zhuan)。断电后主(zhu)电动(dong)(dong)(dong)(dong)(dong)机停转(zhuan)(zhuan)(zhuan),推(tui)杆(gan)叶(ye)轮(lun)也停转(zhuan)(zhuan)(zhuan),失(shi)去油压,活塞(sai)在外力(li)作用下(xia)〔弹簧(huang)复位)迅(xun)速(su)下(xia)降,回到(dao)起(qi)始位置(zhi),闸瓦制动(dong)(dong)(dong)(dong)(dong)。

    对于电(dian)(dian)(dian)(dian)压等级(ji)与主(zhu)(zhu)(zhu)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)不一(yi)致(zhi)的驱(qu)动(dong)(dong)方(fang)式,推杆(gan)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)应另取电(dian)(dian)(dian)(dian)像,但要注(zhu)意(yi)(yi)与主(zhu)(zhu)(zhu)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)实现联锁控制(zhi),以(yi)免在主(zhu)(zhu)(zhu)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)运转当巾因推杆(gan)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)失电(dian)(dian)(dian)(dian)制(zhi)动(dong)(dong)而导致(zhi)主(zhu)(zhu)(zhu)电(dian)(dian)(dian)(dian)动(dong)(dong)机(ji)过载或(huo)烧瓦(wa)。这就是液压制(zhi)动(dong)(dong)器在使用时需要注(zhu)意(yi)(yi)的一(yi)些(xie)地方(fang)。

    对于机(ji)器设备(bei)来说,不管它的(de)运转是(shi)(shi)否正常,制动装(zhuang)置(zhi)都(dou)是(shi)(shi)其(qi)必须正常工作的(de),这是(shi)(shi)关系(xi)到生产是(shi)(shi)否能安全运行(xing)的(de)关键。
