2.归于第二区段毛病
    (1)连杆与内提高臂的衔接销折断 ,连杆掉落 ,内提高臂得不到动力。确诊办法是:在液压泵正常作业时 ,用手扳起外提高臂数次 ,感受内提高臂是不是推进活塞 ,假如无任何力感 ,可根本断定内提高臂与连杆脱开。此刻应分化后盖查看 ,假如是内提高臂与连杆的衔接销折断 ,可替换一个稍细的销子 ,使销子不直接承受力 ,而使连杆球面与内提高臂凹面直触摸摸传递动力 ,否则销子会持续折断。连杆与内提高臂衔接销子折断后 ,连杆球面有能够直接顶在内提高臂凹坑的边际 ,这样等于加长了连杆。提高时活塞不能准时抵达泄油方位 ,因而 ,连杆有能够把内提高臂顶断 ,乃至顶破后盖。这种毛病发作时伴有一定的响声 ,一旦发现 ,应立即停车 ,替换新件。
