3、行走時不能變速其壓路機的變速機構分為兩種，一種是靠變量馬達實現變速，另一種是靠定量馬達和變速箱實現變速。1)變bian量liang馬ma達da機ji構gou的de不bu能neng變bian速su是shi由you於yu變bian量liang馬ma達da的de排pai量liang控kong製zhi機ji構gou不bu能neng正zheng常chang打da開kai或huo出chu現xian故gu障zhang產chan生sheng的de，首shou先xian要yao檢jian查zha行xing走zou速su度du控kong製zhi開kai關guan是shi否fou良liang好hao，變bian速su電dian磁ci閥fa是shi否fou正zheng常chang，並bing在zai電dian磁ci閥fa部bu位wei測ce量liang電dian路lu是shi否fou通tong暢chang，保bao證zheng電dian磁ci閥fa能neng順shun利li打da開kai並bing接jie通tong變bian速su控kong製zhi油you路lu，保bao證zheng其qi壓ya力li正zheng常chang(其壓力為補油壓力)。如上麵一切良好，則馬達損壞。(2)定量馬達變速箱機構的不能變速，其判斷相對簡單，如定量馬達工作壓力正常，則是變速箱損壞，將其恢複即可實現變速。
第二，振動係統故障分析其故障主要表現為無振動或振動無力(頻率不夠，整車共振)，其係統根據泵馬達的形式分為：齒輪泵/齒輪馬達/起振閥組成的係統和柱塞泵/zhusaimadazuchengdexitong。duiyuchilunbeng，xianjianzhayouxiangyouweishifouzhengchang，ranhoujianzhaqizhenfa，qizhenfafenliangzhong，yizhongweijixielaxiankongzhideyiliujiezhifa，lingyizhongweidiancikongzhideyiliujiezhifa。jianzhajixielaxiankongzhideyiliujiezhifashi，yaokankongzhilaxianshifoulianjiezhengchang，yiliufajifatineishifouyouzazhi，xingchengkadaixianxiang。duiyudiancikongzhideyingjianzhazhendongkaiguanjidianlushifouzhengchang，diancitiegongzuoshifouzhengchang，fatineidefaxinyuyiliufashifouzhengchang。ruyishangjianzhaqizhenfalianghao，zeduimadadejinyoukouguanlubisi，zaibisideguanluqian，jiazhuangceyazhuangzhi，yalibiaodeceliangfanweiwei0-400KG，開啟振動，此時測得的壓力峰值(根據油泵的額定工作壓力)最zui大da不bu超chao過guo油you泵beng的de額e定ding壓ya力li。如ru壓ya力li正zheng常chang，連lian接jie馬ma達da，開kai啟qi振zhen動dong，如ru馬ma達da正zheng常chang，開kai啟qi振zhen動dong的de峰feng值zhi壓ya力li應ying為wei之zhi前qian測ce得de的de壓ya力li，並bing隨sui振zhen動dong輪lun轉zhuan速su的de提ti高gao，壓ya力li下xia降jiang(此時壓力根據工作現場的不同會有所不同，但要保持平穩)，整zheng車che無wu共gong振zhen現xian象xiang。如ru此ci時shi測ce得de壓ya力li達da不bu到dao峰feng值zhi，且qie振zhen動dong輪lun工gong作zuo頻pin率lv不bu足zu，整zheng車che共gong振zhen，為wei馬ma達da損sun壞huai，如ru此ci時shi振zhen動dong輪lun不bu工gong作zuo，則ze為wei馬ma達da與yu振zhen動dong輪lun偏pian心xin軸zhou的de連lian軸zhou套tao損sun壞huai;在測得的峰值不降時，振動輪保持不動，則為振動輪偏心軸咬死。
對於柱塞泵/馬ma達da組zu成cheng的de振zhen動dong係xi統tong，其qi判pan斷duan方fang法fa同tong判pan斷duan行xing走zou係xi統tong故gu障zhang類lei似si。首shou先xian，應ying檢jian查zha油you箱xiang油you位wei是shi否fou正zheng常chang，油you泵beng進jin油you係xi統tong的de濾lv芯xin是shi否fou堵du塞sai，如ru以yi上shang正zheng常chang，在zai振zhen動dong泵beng補bu油you測ce壓ya口kou安an裝zhuang範fan圍wei為wei0-40KG的壓力表，測量補油壓力，此時壓力值應在18-24KG之zhi間jian，如ru壓ya力li不bu足zu或huo無wu壓ya力li，則ze為wei補bu油you泵beng損sun壞huai或huo振zhen動dong泵beng無wu動dong力li輸shu入ru。如ru壓ya力li正zheng常chang，則ze檢jian查zha振zhen動dong泵beng電dian磁ci閥fa是shi否fou完wan好hao，同tong時shi將jiang振zhen動dong泵beng兩liang個ge高gao壓ya口kou閉bi死si，並bing安an裝zhuang0-600KG的壓力表，開啟振動，此時測得的高壓峰值壓力為350-420KG，qiebuyouyalibujiangweizhengchang。liantongmadayoulu，zaizhongfuceliangzhendongkaiqishidefengzhiyalihebuyouyali，cishifengzhiyalishunjiandadaodingfeng，bingsuizhendonglunzhuansudetigaoyalixiajiang，baochiwending，buyouyalibujiangweizhengchang。rucishi，cededezhendongyalidabudaofengzhi，qiebuyouyalixiajiang，zhengchegongzhen，zeweimadasunhuai，rucishizhendonglunbudong，zeweimadayuzhendonglunpianxinzhoudelianzhoutaosunhuai。rucishi，cededezhendongyalidadaofengzhi，qieyalibujiang，zhendonglunbugongzuo，zeweizhendonglunpianxinzhouyaosi。
