一、连轴器安装错误

1、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，就会使轴承轴向受力，如果长期承受轴向受力，轴承就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。      

二、同轴度超差

1、如果安装时同轴度超过规定值，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Zui粗的地方），同轴度一般控制在≦0.1毫米左右为好。

三、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超过标准，如果过滤器精度不够或无过滤器，泵芯就会很快划伤并损坏。

力士乐叶片泵都会有异常的现象呢？

四、油液变质

1、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大大的缩短，甚至将叶片及泵芯粘死不能运动。

2、抗磨液压油的使用寿命按石油公司介绍是2000-3000小时（连续半年），环境较好时可延长寿命至6000小时（约一年），所以，建议客户每年更换一次新油。

四、油温太高

1、由于未装冷却装置，在机器连续使用中，油温会不断升高。如果油温长期高达70°以上时，油泵寿命会大大缩短，一般在半年到一年中就会损坏。

五、油中进水

1、在有水冷却的装置中，由于密封不好导致水进入油液中，油液呈乳白状（乳化），油泵内部金属零件会生锈或局部锈蚀，泵在高速旋转中会加速磨损并缩短寿命，油泵的轴封也会早期损坏并使泵轴漏油。

六、变换油口方向

1、当油口方向不合适，没有经验的客户自己调整时，未将泵芯肖子插进肖孔里去（旋转时拔出造成），这时油泵吸油口空间缩小，吸油遇阻吸油不畅，表现为：噪音特大，压力摆动，长时间使用会使油温升高过快，定子内曲线冲击成波纹状后寿命会缩短。再有，旋转时将密封圈切边或螺钉紧固不匀还会产生漏油现象。
