汕头比亚迪电动叉车货叉升降异常排查思路(Figure1)


一、故障初步现场核验

接到货叉升降异常反馈后,首先要第一时间核验故障发生的具体场景,确认是货叉完全无法升降、升降卡顿乏力,还是升降到特定高度后出现卡滞等不同情况。先尝试将电动叉车断电静置30秒后重新启动,再次操作升降控制手柄,排查是否是车载电控系统临时数据错乱引发的误锁止。同时检查操作面板上是否有对应的故障报错提示,查看液压油箱的油位是否处于标准刻度区间,观测液压管路各个接口位置有没有明显的渗油、漏油痕迹,初步排除基础操作类和外观可见的明显故障,避免不必要的拆解操作。

二、液压动力系统分步排查

如果初步核验没有发现明显异常,接下来可以针对液压动力系统做逐项排查。通电状态下操作升降手柄,听升降驱动电机的运转声音是否平稳,有没有出现空转、异响或者动力不足的情况,确认电机供电线路的接线端子有没有松动脱落。随后检查液压泵站的压力调节阀位置是否出现偏移,液压油进油滤芯有没有因长期使用堆积杂质造成堵塞,这类问题都会直接导致液压动力输出不足,引发货叉升降乏力或者完全无法升起的问题,排查过程中要按照电路、泵站、液压油的顺序逐一验证,不要随意调整压力阀的预设参数。

三、货叉门架机械结构排查

排除液压动力系统故障后,就可以针对货叉配套的门架机械结构做细致检查。首先查看门架两侧的升降链条张紧度是否保持一致,有没有出现单侧链条锈蚀、卡滞的情况,随后检查货叉滑道内侧的承重滚轮有没有出现过度磨损、移位的问题,清理门架缝隙处堆积的包装带、碎塑料、生产废料等异物,这类异物卡滞在门架滑道缝隙中,也会直接阻碍货叉的正常升降动作,不少轻微升降卡顿的问题清理完异物后就能直接恢复正常。
