大金柱塞泵常见故障处理1．液压泵输出流量不足或不输出油液(1)吸入量不足。原因是吸油管路上的阻力过大或补油量不足。如泵的转速过大，油箱中液面过低，进油管漏气，滤油器堵塞等。(2)泄漏量过大。原因是泵的间隙过大，密封不良造成。如配油盘被金属碎片、铁屑等划伤，端面漏油；变量机构中的单向阀密封面配合不好，泵体和配油盘的支承面有砂眼或研痕等。可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位。3)倾斜盘倾角太小，泵的排量少，这需要调节变量活塞，增加斜盘倾角。2．中位时排油量不为零变量式轴向柱塞泵的斜盘倾角为零时称为中位，此时泵的输出流量应为零。但有时会出现中位偏离调整机构中点的现象，在中点时仍有流量输出。其原因是控制器的位置偏离、松动或损伤，需要重新调零、紧固或更换。泵的角度维持力不够、倾斜角耳轴磨损也会产生这种现象。3．输出流量波动输出流量波动与很多因素有关。对变量泵可以认为是变量机构的控制不佳造成，如异物进入变量机构，在控制活塞上划出阶痕、磨痕、伤痕等，造成控制活塞运动不稳定。由于放大器能量不足或零件损坏、含有弹簧的控制活塞的阻尼器效能差，都会造成控制活塞运动不稳定。流量不稳定又往往伴随着压力波动。这类故障一般要拆开液压泵，更换受损零部件，加大阻尼，提高弹簧刚度和控制压力等
