【壓(ya)路(lu)機維修】壓(ya)路(lu)機壞了怎么(me)辦 壓(ya)路(lu)機常見故(gu)障解決(jue)方法
1.燃油管路空氣排除方法
壓路機的柴油機在使用過(guo)程(cheng)中(zhong),因油(you)箱(xiang)中(zhong)缺少柴油(you)而熄火。柴油(you)機熄火后(hou),油(you)箱(xiang)中(zhong)雖加(jia)上柴油(you),但(dan)此時(shi)柴油(you)管路(lu)中(zhong)已(yi)經進入空氣(qi),使用手油(you)泵已(yi)無法恢復供油(you)。
為排除柴(chai)(chai)(chai)(chai)油(you)(you)管(guan)路中(zhong)的空氣(qi),使該柴(chai)(chai)(chai)(chai)油(you)(you)機順利啟動,我們采取以下方法:首先,找來1個(ge)小盆并(bing)盛裝一(yi)定量柴(chai)(chai)(chai)(chai)油(you)(you),將(jiang)(jiang)其(qi)放置在(zai)比柴(chai)(chai)(chai)(chai)油(you)(you)泵略高的位置;其(qi)次(ci),將(jiang)(jiang)油(you)(you)箱連接(jie)手油(you)(you)泵的柴(chai)(chai)(chai)(chai)油(you)(you)管(guan)拆下,**這個(ge)小盆的柴(chai)(chai)(chai)(chai)油(you)(you)中(zhong);再次(ci),用手油(you)(you)泵泵送(song)柴(chai)(chai)(chai)(chai)油(you)(you),將(jiang)(jiang)低壓油(you)(you)路中(zhong)的空氣(qi)排除干凈;最(zui)后(hou),將(jiang)(jiang)油(you)(you)箱連接(jie)手油(you)(you)泵的柴(chai)(chai)(chai)(chai)油(you)(you)管(guan)裝復(fu)后(hou)試機,該柴(chai)(chai)(chai)(chai)油(you)(you)機啟動正常(chang)。
2.電磁閥損壞處置方法
如(ru)果遇到柴油機啟動困難,每(mei)次啟動需要較長(chang)時(shi)間,才可將該(gai)柴油機勉(mian)強啟動的情(qing)況。我們初步(bu)認為是噴油器磨損霧化(hua)不良(liang)(liang)所致,但檢(jian)查(cha)噴油器、噴油泵均良(liang)(liang)好。再檢(jian)查(cha)啟動電磁閥(fa)時(shi),發現其電磁鐵沒有吸引力(li)。
我(wo)們將(jiang)(jiang)啟動電(dian)磁(ci)閥(fa)(fa)拆下,用手將(jiang)(jiang)噴油(you)(you)(you)泵(beng)與(yu)電(dian)磁(ci)閥(fa)(fa)連接的(de)油(you)(you)(you)閥(fa)(fa)桿(gan)拽住時(shi),柴油(you)(you)(you)機可順(shun)利啟動,由此(ci)說明該電(dian)磁(ci)閥(fa)(fa)已經損壞。由于附近市場上(shang)暫時(shi)購買(mai)不(bu)到(dao)新的(de)電(dian)磁(ci)閥(fa)(fa),為(wei)此(ci)我(wo)們用細銅絲將(jiang)(jiang)噴油(you)(you)(you)泵(beng)油(you)(you)(you)閥(fa)(fa)桿(gan)捆綁起來不(bu)讓(rang)其回(hui)位,并將(jiang)(jiang)電(dian)磁(ci)閥(fa)(fa)襯墊加厚(hou),防止噴油(you)(you)(you)泵(beng)油(you)(you)(you)閥(fa)(fa)桿(gan)孔口向(xiang)外漏油(you)(you)(you)。經過以上(shang)處(chu)理后將(jiang)(jiang)電(dian)磁(ci)閥(fa)(fa)裝(zhuang)復,該壓路機即(ji)(ji)投入了使用。待采購到(dao)新啟動電(dian)磁(ci)閥(fa)(fa)后再予以更換即(ji)(ji)可。
3.前輪支承件變形修復方法
當靜壓壓路機發生無法啟動故障時,當時為了啟動該壓路機,在現場使(shi)(shi)用裝載機進行頂(ding)推啟動(dong),結果(guo)造成該(gai)壓(ya)路機支(zhi)承前輪的(de)方(fang)框發生變形(xing),前叉與(yu)立軸配合的(de)軸套焊接處錯位,該(gai)壓(ya)路機無法使(shi)(shi)用。
通常修(xiu)復(fu)(fu)該故障需將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)、立軸(zhou)與(yu)前(qian)(qian)(qian)(qian)(qian)叉(cha)拆(chai)解,但是這(zhe)樣(yang)修(xiu)理費時費力。為此(ci),我們采用了以下(xia)簡易的(de)恢復(fu)(fu)方(fang)(fang)法:首(shou)先,將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)調整到正前(qian)(qian)(qian)(qian)(qian)方(fang)(fang)向;其次,將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)、前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)及前(qian)(qian)(qian)(qian)(qian)叉(cha)橫梁用木料墊住,使(shi)其在轉(zhuan)(zhuan)(zhuan)動(dong)轉(zhuan)(zhuan)(zhuan)向盤(pan)時前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)不產(chan)生轉(zhuan)(zhuan)(zhuan)動(dong);再(zai)次,轉(zhuan)(zhuan)(zhuan)動(dong)轉(zhuan)(zhuan)(zhuan)向盤(pan),記住轉(zhuan)(zhuan)(zhuan)向盤(pan)旋(xuan)轉(zhuan)(zhuan)(zhuan)總圈(quan)數,轉(zhuan)(zhuan)(zhuan)到極限位(wei)置再(zai)轉(zhuan)(zhuan)(zhuan)回一(yi)半總圈(quan)數,錯位(wei)的(de)前(qian)(qian)(qian)(qian)(qian)叉(cha)與(yu)立軸(zhou)配合(he)的(de)軸(zhou)套(tao)便(bian)可回到正確位(wei);然后,拆(chai)下(xia)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)兩側的(de)14只(zhi)固定螺栓,用千(qian)斤頂將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)頂起約400mm,使(shi)其離開前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)軸(zhou);最(zui)后,用電(dian)焊將(jiang)(jiang)(jiang)立軸(zhou)軸(zhou)套(tao)焊接(jie)牢固,松去千(qian)斤頂,落下(xia)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)叉(cha),將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)與(yu)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)軸(zhou)裝復(fu)(fu)。這(zhe)樣(yang)做只(zhi)需1個人便(bian)可將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)變(bian)形(xing)調整到位(wei)。
4.變速桿定位不良修復方法
靜(jing)壓光輪壓路(lu)機所配變速(su)桿定位銷易掉出或(huo)被(bei)切斷(duan),從而(er)造成(cheng)變速(su)桿不能定位。該定位銷直徑為4mm,用于防止(zhi)變速(su)桿轉動。
為解決這一問題,我(wo)們采取以下方法:首先,將(jiang)變(bian)速桿(gan)(gan)銷(xiao)孔的直徑擴大(da)到5mm,攻M6內螺(luo)紋;其次(ci),將(jiang)變(bian)速桿(gan)(gan)銷(xiao)槽寬(kuan)度(du)修改為6mm;最后(hou),配置1條(tiao)M6螺(luo)釘和1只M6螺(luo)母,將(jiang)該螺(luo)釘擰入座(zuo)銷(xiao)孔,退回(hui)半圈后(hou)將(jiang)螺(luo)母鎖緊。
5.密封圈漏油解決方法
振動(dong)壓路機的振動(dong)閥(fa)(fa)漏油,更(geng)換了Y形密封圈后,使用時(shi)間(jian)不(bu)長又產生漏油。檢查發現振動(dong)閥(fa)(fa)經長期(qi)使用后,閥(fa)(fa)芯(xin)上蓋與閥(fa)(fa)芯(xin)之間(jian)磨損嚴重。
為解決這一問題,我們采(cai)用添加(jia)O形或扁形密封(feng)圈(quan)的(de)方(fang)法,即將O形或扁形密封(feng)圈(quan)加(jia)裝在Y形密封(feng)圈(quan)的(de)槽內。該(gai)振動閥加(jia)裝密封(feng)圈(quan)后未出現漏油(you)現象(xiang),由此證明該(gai)方(fang)法取得較好效果。
