1.燃油管路空氣排除方法

壓路機的柴油機在使(shi)用過程(cheng)中，因(yin)油(you)(you)箱中缺少柴(chai)油(you)(you)而熄(xi)火。柴(chai)油(you)(you)機熄(xi)火后，油(you)(you)箱中雖加上柴(chai)油(you)(you)，但此(ci)時柴(chai)油(you)(you)管路中已(yi)經進入空氣，使(shi)用手(shou)油(you)(you)泵已(yi)無法(fa)恢復供油(you)(you)。

為排(pai)除柴(chai)(chai)油(you)管路(lu)中(zhong)的(de)空氣，使該柴(chai)(chai)油(you)機順利啟動，我們采(cai)取以(yi)下方法：首先，找來1個(ge)小(xiao)(xiao)盆(pen)并盛裝一定量柴(chai)(chai)油(you)，將其(qi)放置在比(bi)柴(chai)(chai)油(you)泵略高的(de)位置;其(qi)次(ci)，將油(you)箱連接手(shou)油(you)泵的(de)柴(chai)(chai)油(you)管拆(chai)下，**這(zhe)個(ge)小(xiao)(xiao)盆(pen)的(de)柴(chai)(chai)油(you)中(zhong);再次(ci)，用手(shou)油(you)泵泵送(song)柴(chai)(chai)油(you)，將低壓油(you)路(lu)中(zhong)的(de)空氣排(pai)除干(gan)凈;最后，將油(you)箱連接手(shou)油(you)泵的(de)柴(chai)(chai)油(you)管裝復后試機，該柴(chai)(chai)油(you)機啟動正常。

2.電磁閥損壞處置方法

如果遇到柴(chai)油(you)(you)(you)機啟(qi)動困難，每次啟(qi)動需要較長(chang)時(shi)間，才可將該柴(chai)油(you)(you)(you)機勉強啟(qi)動的(de)情況。我(wo)們初步認為是噴油(you)(you)(you)器磨損霧化不(bu)良所(suo)致，但檢(jian)查噴油(you)(you)(you)器、噴油(you)(you)(you)泵均良好(hao)。再檢(jian)查啟(qi)動電磁閥時(shi)，發現其電磁鐵沒有吸引力。

我們將(jiang)(jiang)啟(qi)動(dong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)拆(chai)下(xia)，用手(shou)將(jiang)(jiang)噴油(you)泵與(yu)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)連接的(de)油(you)閥(fa)(fa)桿(gan)(gan)拽住時(shi)，柴油(you)機可(ke)順利啟(qi)動(dong)，由此(ci)說明該電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)已經(jing)損壞(huai)。由于附近市場上暫時(shi)購買不到新(xin)的(de)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)，為此(ci)我們用細銅絲將(jiang)(jiang)噴油(you)泵油(you)閥(fa)(fa)桿(gan)(gan)捆綁起來(lai)不讓其(qi)回位(wei)，并將(jiang)(jiang)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)襯墊加厚(hou)，防(fang)止噴油(you)泵油(you)閥(fa)(fa)桿(gan)(gan)孔口向外漏油(you)。經(jing)過以上處理(li)后將(jiang)(jiang)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)裝(zhuang)復，該壓(ya)路機即(ji)投入了使(shi)用。待(dai)采購到新(xin)啟(qi)動(dong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)后再予以更換即(ji)可(ke)。

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(xian)場使(shi)用裝載機進行頂推啟動，結(jie)果造成該壓路機支承前輪的方框發生變形，前叉與立軸配合(he)的軸套(tao)焊接處(chu)錯位(wei)，該壓路機無法使(shi)用。

通常修(xiu)復該故障需將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)、立軸(zhou)與前(qian)(qian)(qian)(qian)(qian)(qian)叉拆(chai)解(jie)，但是這(zhe)樣(yang)修(xiu)理費時(shi)費力(li)。為此，我們采用了以下(xia)簡易的(de)恢復方法：首(shou)先，將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)調(diao)整到正(zheng)前(qian)(qian)(qian)(qian)(qian)(qian)方向(xiang)(xiang);其(qi)(qi)次(ci)，將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)、前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)及(ji)前(qian)(qian)(qian)(qian)(qian)(qian)叉橫梁用木料墊住(zhu)，使其(qi)(qi)在轉(zhuan)動(dong)轉(zhuan)向(xiang)(xiang)盤時(shi)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)不產生轉(zhuan)動(dong);再(zai)次(ci)，轉(zhuan)動(dong)轉(zhuan)向(xiang)(xiang)盤，記住(zhu)轉(zhuan)向(xiang)(xiang)盤旋轉(zhuan)總圈數，轉(zhuan)到極限位(wei)(wei)(wei)置(zhi)再(zai)轉(zhuan)回(hui)(hui)一半總圈數，錯(cuo)位(wei)(wei)(wei)的(de)前(qian)(qian)(qian)(qian)(qian)(qian)叉與立軸(zhou)配合的(de)軸(zhou)套(tao)(tao)便(bian)可(ke)回(hui)(hui)到正(zheng)確(que)位(wei)(wei)(wei);然后，拆(chai)下(xia)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)兩側的(de)14只(zhi)固定螺(luo)栓，用千斤(jin)頂將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)頂起約400mm，使其(qi)(qi)離開前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)軸(zhou);最后，用電焊(han)將(jiang)(jiang)(jiang)立軸(zhou)軸(zhou)套(tao)(tao)焊(han)接(jie)牢固，松去(qu)千斤(jin)頂，落下(xia)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)叉，將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)與前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)軸(zhou)裝復。這(zhe)樣(yang)做只(zhi)需1個人便(bian)可(ke)將(jiang)(jiang)(jiang)前(qian)(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)(lun)方框(kuang)變形調(diao)整到位(wei)(wei)(wei)。

4.變速桿定位不良修復方法

靜壓(ya)光輪壓(ya)路機(ji)所配(pei)變(bian)(bian)速(su)桿(gan)定(ding)(ding)位(wei)銷易掉出或被切斷，從而造成(cheng)變(bian)(bian)速(su)桿(gan)不能定(ding)(ding)位(wei)。該定(ding)(ding)位(wei)銷直(zhi)徑為4mm，用于防(fang)止變(bian)(bian)速(su)桿(gan)轉動。

為解決這一問題(ti)，我們采取(qu)以下(xia)方(fang)法：首先，將(jiang)(jiang)變速桿(gan)銷孔(kong)的(de)直(zhi)徑擴大到5mm，攻M6內(nei)螺紋(wen);其次，將(jiang)(jiang)變速桿(gan)銷槽寬度修改為6mm;最后(hou)，配置1條M6螺釘和1只M6螺母(mu)，將(jiang)(jiang)該螺釘擰入座(zuo)銷孔(kong)，退回半圈后(hou)將(jiang)(jiang)螺母(mu)鎖緊(jin)。

5.密封圈漏油解決方法

振(zhen)動壓路機的振(zhen)動閥(fa)(fa)(fa)漏(lou)(lou)油，更換了Y形密封圈后(hou)，使用時(shi)間(jian)(jian)不長又產生(sheng)漏(lou)(lou)油。檢查發現振(zhen)動閥(fa)(fa)(fa)經長期使用后(hou)，閥(fa)(fa)(fa)芯(xin)上蓋與閥(fa)(fa)(fa)芯(xin)之間(jian)(jian)磨損(sun)嚴重。

為(wei)解決這一(yi)問題，我(wo)們采用添(tian)加O形(xing)(xing)(xing)或扁形(xing)(xing)(xing)密封圈(quan)(quan)的方法(fa)，即(ji)將O形(xing)(xing)(xing)或扁形(xing)(xing)(xing)密封圈(quan)(quan)加裝(zhuang)在(zai)Y形(xing)(xing)(xing)密封圈(quan)(quan)的槽內。該振動閥加裝(zhuang)密封圈(quan)(quan)后未出現漏油現象，由此證明該方法(fa)取得較好效(xiao)果。
