液壓制動器常見故障之一

　　說(shuo)起(qi)制(zhi)動(dong)器來，大家便會都會想到行車(che)制(zhi)動(dong)器和(he)駐(zhu)車(che)制(zhi)動(dong)器來，那么除(chu)此(ci)之外還有(you)(you)哪些呢?還有(you)(you)液壓制(zhi)動(dong)器和(he)塊式制(zhi)動(dong)器等等很多(duo)的種(zhong)類。

　　那(nei)么液(ye)壓制動(dong)器在使(shi)用過程中都會(hui)或多(duo)或少的出(chu)現一些故障，那(nei)么下面就給大(da)家介紹一些液(ye)壓制動(dong)器常會(hui)遇到的故障。

　　液壓制動(dong)體系(xi)由真(zhen)空助力器(qi)、液壓傳動(dong)裝置和制動(dong)器(qi)三(san)有些(xie)組(zu)成。行車(che)中，若是發現制動(dong)失(shi)靈或有異響，應立即泊車(che)查(cha)看，及時掃除，尤其在(zai)油(you)罐(guan)車(che)及爆(bao)炸器(qi)件運(yun)輸車(che)在(zai)運(yun)輸過程(cheng)中更要注意。

　　真空助力器的毛病(bing)確(que)診

　　先查(cha)看其密封(feng)性。發動(dong)(dong)(dong)發動(dong)(dong)(dong)機(ji)(ji)(ji)，加(jia)(jia)快到中等(deng)轉速(su)(1500r/min左右(you))后，將(jiang)發動(dong)(dong)(dong)機(ji)(ji)(ji)熄火(huo)，一(yi)起敏捷抬(tai)起加(jia)(jia)快踏(ta)(ta)板，使(shi)發動(dong)(dong)(dong)機(ji)(ji)(ji)進(jin)氣管(guan)中有校(xiao)高的真(zhen)空度。發動(dong)(dong)(dong)機(ji)(ji)(ji)熄火(huo)約(yue)90秒后，踩下(xia)(xia)制(zhi)動(dong)(dong)(dong)踏(ta)(ta)板，此刻若(ruo)能聽(ting)到真(zhen)空助力器鄰(lin)近有清淅的“呼”的進(jin)氣聲(sheng)，抬(tai)起制(zhi)動(dong)(dong)(dong)踏(ta)(ta)板再踩一(yi)下(xia)(xia)，又能聽(ting)到一(yi)次進(jin)氣聲(sheng)，闡(chan)明真(zhen)空助力器密封(feng)杰出。不然，是真(zhen)空單(dan)向(xiang)閥不緊密、真(zhen)空管(guan)路阻塞或走漏，應拆檢(jian)修補。

　　查看(kan)(kan)完真(zhen)空(kong)助(zhu)力(li)(li)器的密封(feng)性后，再(zai)查看(kan)(kan)其作業效能。在發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)熄火狀態下(xia)(xia)，用力(li)(li)踩下(xia)(xia)制(zhi)動(dong)(dong)(dong)(dong)(dong)踏(ta)板(ban)(ban)數次，免除助(zhu)力(li)(li)泵中的真(zhen)空(kong)。然后用恰當的力(li)(li)再(zai)踩下(xia)(xia)制(zhi)動(dong)(dong)(dong)(dong)(dong)踏(ta)板(ban)(ban)，并使制(zhi)動(dong)(dong)(dong)(dong)(dong)踏(ta)板(ban)(ban)堅持(chi)不(bu)動(dong)(dong)(dong)(dong)(dong)。此刻發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)，若能明(ming)(ming)顯地感(gan)(gan)受到制(zhi)動(dong)(dong)(dong)(dong)(dong)踏(ta)板(ban)(ban)下(xia)(xia)落一段距離，則闡(chan)明(ming)(ming)真(zhen)空(kong)助(zhu)力(li)(li)器在起效果(guo)。若在發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)機(ji)發(fa)(fa)動(dong)(dong)(dong)(dong)(dong)剎那間沒(mei)有感(gan)(gan)受到制(zhi)動(dong)(dong)(dong)(dong)(dong)踏(ta)板(ban)(ban)下(xia)(xia)沉或感(gan)(gan)受不(bu)明(ming)(ming)顯，闡(chan)明(ming)(ming)真(zhen)空(kong)助(zhu)力(li)(li)器已損失助(zhu)力(li)(li)效果(guo)，應進一步拆檢修補。

　　看過以上的有關液壓制動器真空助力(li)器的(de)相關的(de)故(gu)障之(zhi)后，你是不是有所(suo)了解。
