對于小型壓路機而言,方向盤可謂是不可或缺的一個重要操控配件,一旦方向盤出現故障,勢必會直接影響整個小型壓路機的正常運行。為(wei)保障壓路(lu)機(ji)的正常使(shi)用,避免造成(cheng)嚴(yan)重人(ren)身傷亡事故,我司(si)現就(jiu)小型壓路(lu)機(ji)使(shi)用過(guo)程中較常發生(sheng)的幾類方向盤(pan)故障及其成(cheng)因作以(yi)逐一分析,并提出相應解決對策以(yi)供參考。

小型(xing)壓路機(ji)方向盤失(shi)靈

1.操作小型壓路機時發現(xian)方(fang)向盤自轉、左右擺動(dong)、晃動(dong)較大,應(ying)(ying)檢查轉子和(he)傳動(dong)聯軸器相干位置是否對應(ying)(ying)合理或螺(luo)絲(si)松動(dong),驅動(dong)傳動(dong)軸齒和(he)正(zheng)轉子齒根應(ying)(ying)相互(hu)對應(ying)(ying)。

2.檢測(ce)方向盤是(shi)否(fou)能主動回中(zhong),回中(zhong)位(wei)置是(shi)否(fou)正常(chang)壓降是(shi)否(fou)增長(chang),檢查彈簧片是(shi)否(fou)磨損或(huo)折(zhe)斷(duan),如彈簧片已折(zhe)斷(duan)請替換,替換后(hou)使方向盤回中(zhong)即(ji)可。

3.方向盤不能轉(zhuan)動(dong)(dong),壓力明(ming)顯(xian)增大或難以(yi)(yi)轉(zhuan)動(dong)(dong),檢(jian)查撥銷是(shi)否折斷,傳(chuan)動(dong)(dong)聯動(dong)(dong)軸是(shi)否折斷、變形、開口、磨(mo)損(sun)。如發現以(yi)(yi)上(shang)情況應替換小型壓路機(ji)撥銷及傳(chuan)動(dong)(dong)聯動(dong)(dong)軸,在注入傳(chuan)動(dong)(dong)機(ji)油。

4.行駛(shi)過程(cheng)中(zhong)(zhong)或小(xiao)型壓路機(ji)(ji)施工過程(cheng)中(zhong)(zhong),發現轉動(dong)方向(xiang)盤(pan)后車輛(liang)偏方向(xiang)行駛(shi)或車輛(liang)行走時主動(dong)跑偏并發現轉向(xiang)油缸不動(dong)或緩動(dong)。這時應檢查雙(shuang)向(xiang)緩沖閥及雙(shuang)向(xiang)緩沖閥彈簧是(shi)否有(you)雜物,如雙(shuang)向(xiang)緩沖閥失靈請(qing)及時替換,昔換過程(cheng)中(zhong)(zhong)肯定注入機(ji)(ji)油。

小型壓路(lu)機方向盤轉向沉重

轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)沉重(zhong)(zhong)的主要原因及排除(chu)方法是(shi):轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)液壓(ya)油(you)(you)(you)溫度太低,應(ying)當(dang)等液壓(ya)油(you)(you)(you)溫度升高后再開始工作;轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)泵供油(you)(you)(you)不(bu)足。應(ying)檢(jian)(jian)查油(you)(you)(you)泵是(shi)否(fou)磨(mo)損(sun)或損(sun)壞,嚴(yan)重(zhong)(zhong)時(shi)更換油(you)(you)(you)泵總成,轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)油(you)(you)(you)路中(zhong)進入空(kong)氣,造成轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)油(you)(you)(you)缸時(shi)動(dong)時(shi)不(bu)動(dong)。應(ying)排除(chu)系統(tong)(tong)中(zhong)的空(kong)氣,并檢(jian)(jian)查轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)泵吸油(you)(you)(you)管是(shi)否(fou)松動(dong)漏氣;轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)系統(tong)(tong)壓(ya)力(li)低,應(ying)按規定調整滋流閥的壓(ya)力(li),或清(qing)洗溢流閥,更換彈簧或密(mi)封圈;全(quan)(quan)液壓(ya)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)器轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)壓(ya)力(li)過低。應(ying)根據其不(bu)同型號予(yu)以檢(jian)(jian)修(xiu);對于全(quan)(quan)液壓(ya)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)器,可能是(shi)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)器計(ji)量馬達部分(fen)螺栓(shuan)擰(ning)得過緊(jin),應(ying)將螺栓(shuan)放松;對全(quan)(quan)液壓(ya)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)器,可能是(shi)轉(zhuan)(zhuan)(zhuan)向(xiang)(xiang)器內(nei)鋼球單(dan)向(xiang)(xiang)閥失效,應(ying)清(qing)洗出臟(zang)物,使(shi)鋼球與閥體密(mi)封帶接觸(chu)良好。

其他故障

1.撥銷折(zhe)斷、變形及磨損,或者是傳動(dong)聯(lian)動(dong)軸折(zhe)斷、變形、開(kai)口(kou)、磨損都會造成方向盤(pan)不能(neng)轉動(dong),壓力增大(da)。

2.小型壓路機在操(cao)作過(guo)程(cheng)中(zhong),方向盤自轉(zhuan)(zhuan)、左右擺動(dong)、晃動(dong)較大,需(xu)要檢查轉(zhuan)(zhuan)子和傳(chuan)動(dong)聯軸器的位置是否對(dui)應合理或螺絲(si)松動(dong)。

3.當(dang)遇到小型(xing)壓路機行(xing)駛過程中自(zi)動跑偏,或轉動方(fang)向盤(pan)后車輛偏離(li)方(fang)向行(xing)駛的情況時(shi),應(ying)該檢查雙向緩沖閥及彈簧是否有雜物。

在小型(xing)壓(ya)路(lu)機長時(shi)間運行(xing)的過(guo)程中,出現方向(xiang)盤(pan)故障的可能性雖比較大,但只要相(xiang)關使用單位嚴格按照(zhao)相(xiang)應技術(shu)規(gui)程正確加(jia)以運用,并加(jia)強對壓(ya)路(lu)機的定期維(wei)護與保(bao)養,相(xiang)信定能夠大幅降低壓(ya)路(lu)機異常故障發生率,延長機械使用壽命。
