    说起起重(zhong)机(ji)制动器,大家都(dou)不陌生,它(ta)是(shi)(shi)起重(zhong)机(ji)上的(de)刹车装置,它(ta)的(de)使用保障了起重(zhong)机(ji)的(de)安全运行,是(shi)(shi)工(gong)作人(ren)(ren)员人(ren)(ren)身安全的(de)保障。可(ke)是(shi)(shi)由于(yu)使用时(shi)间会(hui)对其造(zao)成一定的(de)磨损,那么在使用时(shi)要注意哪些问题呢(ni)?

    为了减(jian)(jian)轻制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)器的磨损,减(jian)(jian)轻因(yin)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)过猛(meng)发生的冲击和(he)振荡,引警撑持制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)和(he)操操控动(dong)(dong)(dong)(dong)(dong)并(bing)用(yong)。操操控动(dong)(dong)(dong)(dong)(dong)通常为电(dian)力(li)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong),如再生制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)、反接制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)、能耗(hao)(hao)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)和(he)涡流制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)等(deng)。电(dian)力(li)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)仅用(yong)于(yu)(yu)耗(hao)(hao)费动(dong)(dong)(dong)(dong)(dong)能,使(shi)组织安(an)(an)全(quan)减(jian)(jian)速(su)。在与电(dian)力(li)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)并(bing)用(yong)时(shi),撑持制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)器的******安(an)(an)全(quan)系数应独自满意原有(you)的规(gui)则(ze)。也(ye)能够(gou)选用(yong)二次制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)削(xue)减(jian)(jian)磨损和(he)冲击,******制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)用(yong)于(yu)(yu)耗(hao)(hao)费动(dong)(dong)(dong)(dong)(dong)能,使(shi)机(ji)械安(an)(an)全(quan)减(jian)(jian)速(su)并(bing)中(zhong)止,第2次制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)确(que)保撑持制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)的安(an)(an)全(quan),如用(yong)于(yu)(yu)防风制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)。国(guo)家(jia)规(gui)范规(gui)则(ze):关于(yu)(yu)吊钩起(qi)重机(ji),当起(qi)升组织作业等(deng)级等(deng)于(yu)(yu)或(huo)高(gao)于(yu)(yu)M4且额(e)外起(qi)升速(su)度等(deng)于(yu)(yu)或(huo)高(gao)于(yu)(yu)5m/min时(shi),应选用(yong)电(dian)气(qi)制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)办法,确(que)保在0.2-1.0倍额(e)外起(qi)重量范围内的载荷降低时(shi),制(zhi)(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)前的电(dian)机(ji)转(zhuan)速(su)降至同(tong)步转(zhuan)速(su)的1.3以下。

    从以(yi)(yi)上信息(xi)不难看出,起重机(ji)制动(dong)器的磨(mo)损情况应(ying)该定期检查,以(yi)(yi)防起重机(ji)制动(dong)器磨(mo)损而(er)使工作不能正常进行。
