台湾海特克电机组合泵M-VPV2-30-35-1.5-10

（3）丈量液压泵的压力。若压力偏低，则进行调整，加压力仍调不上去，则阐明液压泵严峻磨损。
    经查看丈量液压泵的压力仅为5－7MPa，显着低于液压体系的额外压力。拆开液压泵后发现轴套已磨损，低压区泵壳内壁被齿轮严峻“扫模”，侧壁也稍有磨损。由此可见，形成动臂带载不能进步的主要缘由为：
    a. 液压泵严峻磨损。在低速作业时泵内走漏严峻；高速作业时，泵压力稍有进步，但因为泵的磨损及内泄，容积功率明显下降，很难达到额外压力。液压泵长时间作业又加重了磨损，油温升高，由此形成液压元件磨损及密封件的老化、损坏，丢失密封才能，液压油蜕变，Zui终导致毛病发作。
