五缸柱塞泵，液力端更换了组合阀(进出口阀组装在一起的)，弹簧，弹簧座，密封垫，也拍排空了，进口端换了过滤器，加载后就是不上量，压力表抖动厉害，不知道什么原因
1、供料不足，检查进口管路、进口阀 2、吸排液阀泄露、检查吸排液阀、阀片等。3、泵内有空气，排净空气。你是换完吸排液阀后出现这样问题的吗？如果是那就检查一下这里吧。
对，零件都换完后出现的
那你就检查一下你换的件，液力端更换了组合阀(进出口阀组装在一起的)，弹簧，弹簧座，密封垫
压力表抖动压力大小如何，怎么知道是不上量，是下游流量看还是出口压力表看的
检查有没有缺缸，检查某单向阀状况
找到原因了，组合阀密封垫密封不好，因为泵用了十来年了，泵头里面台阶腐蚀，密封垫厚度不够了，密封垫后面又加了层四氟板，没事了

阀簧断裂，或者单向阀密封面破损造成高低压窜呀
