【壓路(lu)機維修】壓路(lu)機壞了怎么辦(ban) 壓路(lu)機常見故障解決方(fang)法(fa)
1.燃油管路空氣排除方法
壓路機的柴油機在使(shi)用(yong)過程中(zhong)(zhong),因油(you)(you)箱中(zhong)(zhong)缺少(shao)柴油(you)(you)而熄(xi)火。柴油(you)(you)機熄(xi)火后,油(you)(you)箱中(zhong)(zhong)雖加上柴油(you)(you),但(dan)此時(shi)柴油(you)(you)管(guan)路中(zhong)(zhong)已經進(jin)入空氣(qi),使(shi)用(yong)手油(you)(you)泵已無法恢復(fu)供(gong)油(you)(you)。
為排除(chu)柴(chai)(chai)(chai)油(you)(you)(you)管(guan)路中的(de)(de)(de)空(kong)氣,使該柴(chai)(chai)(chai)油(you)(you)(you)機(ji)順利(li)啟動(dong)(dong),我們采取以下(xia)方法(fa):首先,找(zhao)來1個(ge)小盆(pen)并盛裝一(yi)定(ding)量(liang)柴(chai)(chai)(chai)油(you)(you)(you),將其放置在比柴(chai)(chai)(chai)油(you)(you)(you)泵(beng)(beng)略高(gao)的(de)(de)(de)位(wei)置;其次(ci)(ci),將油(you)(you)(you)箱(xiang)連接(jie)(jie)手油(you)(you)(you)泵(beng)(beng)的(de)(de)(de)柴(chai)(chai)(chai)油(you)(you)(you)管(guan)拆下(xia),**這個(ge)小盆(pen)的(de)(de)(de)柴(chai)(chai)(chai)油(you)(you)(you)中;再次(ci)(ci),用手油(you)(you)(you)泵(beng)(beng)泵(beng)(beng)送柴(chai)(chai)(chai)油(you)(you)(you),將低壓油(you)(you)(you)路中的(de)(de)(de)空(kong)氣排除(chu)干凈;最后(hou)(hou),將油(you)(you)(you)箱(xiang)連接(jie)(jie)手油(you)(you)(you)泵(beng)(beng)的(de)(de)(de)柴(chai)(chai)(chai)油(you)(you)(you)管(guan)裝復后(hou)(hou)試機(ji),該柴(chai)(chai)(chai)油(you)(you)(you)機(ji)啟動(dong)(dong)正(zheng)常。
2.電磁閥損壞處置方法
如果(guo)遇到柴油(you)(you)機啟(qi)動(dong)困(kun)難(nan),每(mei)次啟(qi)動(dong)需要(yao)較長時間,才可將該柴油(you)(you)機勉強啟(qi)動(dong)的情況(kuang)。我們初步認為(wei)是噴油(you)(you)器磨損(sun)霧化不良(liang)所(suo)致,但檢查噴油(you)(you)器、噴油(you)(you)泵均良(liang)好。再檢查啟(qi)動(dong)電磁閥時,發現(xian)其電磁鐵沒有吸引力。
我(wo)們將(jiang)啟動電(dian)磁閥(fa)(fa)(fa)(fa)拆下,用手將(jiang)噴油(you)泵(beng)與電(dian)磁閥(fa)(fa)(fa)(fa)連接的油(you)閥(fa)(fa)(fa)(fa)桿拽住時,柴(chai)油(you)機(ji)(ji)可(ke)順(shun)利啟動,由此說明(ming)該(gai)電(dian)磁閥(fa)(fa)(fa)(fa)已經(jing)損壞。由于附(fu)近(jin)市場(chang)上(shang)暫時購(gou)買不(bu)到(dao)新的電(dian)磁閥(fa)(fa)(fa)(fa),為此我(wo)們用細銅絲將(jiang)噴油(you)泵(beng)油(you)閥(fa)(fa)(fa)(fa)桿捆綁起來不(bu)讓(rang)其(qi)回位,并將(jiang)電(dian)磁閥(fa)(fa)(fa)(fa)襯(chen)墊加厚,防止噴油(you)泵(beng)油(you)閥(fa)(fa)(fa)(fa)桿孔口向外漏油(you)。經(jing)過以上(shang)處理后(hou)將(jiang)電(dian)磁閥(fa)(fa)(fa)(fa)裝復(fu),該(gai)壓路機(ji)(ji)即(ji)投(tou)入(ru)了使(shi)用。待采(cai)購(gou)到(dao)新啟動電(dian)磁閥(fa)(fa)(fa)(fa)后(hou)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,在現場使(shi)用裝載(zai)機進(jin)行頂推啟(qi)動,結果造成該壓路機支承(cheng)前(qian)(qian)輪的(de)方框發生變形,前(qian)(qian)叉與立軸配合的(de)軸套焊接處錯位,該壓路機無法使(shi)用。
通常修(xiu)復該故障需將前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)(kuang)、立軸(zhou)(zhou)與(yu)前(qian)(qian)(qian)(qian)(qian)叉(cha)拆解,但是這樣修(xiu)理費時費力。為此,我們采用(yong)了以下簡易的(de)恢復方(fang)(fang)法:首先,將前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)調整到正(zheng)前(qian)(qian)(qian)(qian)(qian)方(fang)(fang)向(xiang)(xiang);其次(ci),將前(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)(kuang)及前(qian)(qian)(qian)(qian)(qian)叉(cha)橫梁用(yong)木料墊住(zhu)(zhu),使其在轉動轉向(xiang)(xiang)盤時前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)不產生轉動;再次(ci),轉動轉向(xiang)(xiang)盤,記住(zhu)(zhu)轉向(xiang)(xiang)盤旋轉總圈(quan)數,轉到極(ji)限位置再轉回(hui)一半總圈(quan)數,錯位的(de)前(qian)(qian)(qian)(qian)(qian)叉(cha)與(yu)立軸(zhou)(zhou)配合(he)的(de)軸(zhou)(zhou)套(tao)便(bian)可回(hui)到正(zheng)確(que)位;然后,拆下前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)(kuang)兩側的(de)14只固定螺(luo)栓(shuan),用(yong)千斤(jin)頂(ding)將前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)(kuang)頂(ding)起約400mm,使其離(li)開前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)軸(zhou)(zhou);最后,用(yong)電焊將立軸(zhou)(zhou)軸(zhou)(zhou)套(tao)焊接牢固,松去千斤(jin)頂(ding),落(luo)下前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)叉(cha),將前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)(kuang)與(yu)前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)軸(zhou)(zhou)裝復。這樣做只需1個(ge)人便(bian)可將前(qian)(qian)(qian)(qian)(qian)輪(lun)(lun)(lun)方(fang)(fang)框(kuang)(kuang)(kuang)變形調整到位。
4.變速桿定位不良修復方法
靜壓光(guang)輪壓路機(ji)所配變速桿(gan)定(ding)位(wei)銷易掉出(chu)或被切斷,從而造成變速桿(gan)不能(neng)定(ding)位(wei)。該定(ding)位(wei)銷直徑為4mm,用(yong)于防(fang)止變速桿(gan)轉動。
為解決這一問題,我們采(cai)取以下(xia)方法:首先,將(jiang)(jiang)變速桿銷(xiao)孔的直徑擴大到5mm,攻M6內(nei)螺紋;其次,將(jiang)(jiang)變速桿銷(xiao)槽(cao)寬度(du)修改為6mm;最(zui)后,配置1條M6螺釘(ding)和(he)1只M6螺母(mu),將(jiang)(jiang)該(gai)螺釘(ding)擰入(ru)座銷(xiao)孔,退(tui)回半圈(quan)后將(jiang)(jiang)螺母(mu)鎖緊(jin)。
5.密封圈漏油解決方法
振(zhen)動(dong)壓路機的振(zhen)動(dong)閥漏油,更換了Y形密(mi)封圈后,使用(yong)時間不長又產生漏油。檢查(cha)發(fa)現振(zhen)動(dong)閥經長期使用(yong)后,閥芯上蓋(gai)與閥芯之間磨損嚴重。
為解決這(zhe)一問題,我(wo)們采用添加O形(xing)或扁(bian)形(xing)密封圈(quan)的方法,即(ji)將O形(xing)或扁(bian)形(xing)密封圈(quan)加裝在Y形(xing)密封圈(quan)的槽內(nei)。該振動閥(fa)加裝密封圈(quan)后未出現漏油(you)現象,由此證明該方法取得較好效果。
