液压泵使用不当的十种表现：
01连轴器安装错误
由于连轴器与轴配合间隙太小或无间隙，在用力敲击时，轴承会受伤，导致轴承早期损坏而影响整个泵芯的寿命。再有，连轴器在安装时如果没有一定的轴向间隙，用螺丝直接硬性将泵安装到泵套上，会使轴承轴向受力，如果长期承受轴向受力，轴承会很快损坏并产生偏心而秧及了泵芯，表面上看象是泵芯出了故障，其实始作俑者是轴承。
02同轴度**差
如果安装时同轴度**过规定值，会使轴承及整个泵芯偏心而早期损坏，轴也会被切断（轴切断在轴头粗的地方），同轴度一般控制在≦0.1毫米左右为好。
03油液太脏
由于油箱不是密封状态，周围粉尘及杂物混入油液中致使油液的清洁度**过标准，如果过滤器精度不够或无过滤器，泵芯会很快划伤并损坏。
04油液变质
由于使用了过期的液压油或再生油，使泵芯零件表面呈黑色状或粘胶状，油中的杂物、毒物及腐蚀性可使油泵早期损坏，再生的过期油因缺乏润滑及抗磨性也会使泵芯寿命的缩短，甚至将叶片及泵芯粘死不能运动。
液压泵常见的一个故障是定子内曲面磨损成撮衣板状的棱子，该现象主要是吸油不畅所致。
原因为:当油泵吸油不足时，压力会时高时低，而叶片**部对定子内曲面的有效接触会随着压力的变化而间歇式脱离与接触，频繁的硬冲击使定子的吸油区便出现了象撮衣板状的棱子了。
带压作业液压泵机械效率高：典型值为0.94，减小了能量损耗； 转速范围宽 － 转速范围为600～2800 rpm（车用型泵为400～2800 rpm），结合在小规格壳体中安装大排量的泵芯组件的方式，可优化工作状态，降低噪声
带压作业液压泵转速低：（600 rpm，车用型泵为400 rpm）、低压力及高粘度（860 cSt，车用型泵为2000 cSt）运行能力 － 使T6 液压泵能适应低温工况，功耗小且无卡滞危险； 压力脉动小 － 约±2 bar，由此可减小液压管道的噪声，并延长液压回路中其它元件的使用寿命
液压泵,液压泵的种类,液压泵的结构形式
利用装有叶片的叶轮高速旋转，将机械能转换为液体的动能与压能而工作的泵，称为液压泵。根据被抽送液体流出叶轮的方向，可分为离心式、轴流式和混流式三种类型。
由于液压泵效率较高、起动方便、性能可靠，而且、扬程适用范围较大，因此，在工程实际中得到了广泛应用。
