“液压泵不出油”几乎所有的故障原因均有可能是压力上不去或者根本无压力的原因：
1、配油盘与壳体端面（固定面）接触不良，之间有较大污物契入，使压油腔部分压力油通过两者之间的间隙流入低压区，输出减小，应拆开清洗，使之密合。
2、配油盘与转子贴合端面（滑动面）拉毛，磨损严重，内泄漏量大，输出不够，可先用较粗（不能太粗）的砂纸打磨拉毛高点，然后用细砂布磨掉凹痕，抛光后使用。
3、定子内孔（内曲线表面）拉毛，磨损，叶片**圆与定子孔内曲面支架的拉毛划伤沟痕漏往吸油区，造成输出不够，可用金相砂纸磨砂定子内曲面。
4、叶片和后钻子组合件（泵芯）装反了
5、泵体有气孔，沙眼，缩松等铸造缺陷，被击穿，使高，低压腔局部连通，吸不上油，此时可能要换液压泵。
6、轴向间隙太大，即液压泵转子厚度与定子厚度和液压泵泵体孔深度尺寸相差太大，或者修理时加了纸垫子，使轴向间隙过大，内泄漏过大，内泄漏，而使输出减小。
7、变量机构调的不对，或者有毛病，可在查明原因后酌情处理
8、配油盘端面磨损或拉有沟槽，内泄漏量大，输出 不够，一般要研磨配油盘端面。
9、滤油器堵塞，或过滤精度太高，不上油或上油很少（视堵塞程度而定），可拆卸清洗。
10、液压油的粘度过低，特别是对小容量液压泵，当油液粘度过低或因油温温升过高，液压泵打出的油往往不能加载上升到所需压力。这是油液粘度过低和温升造成内泄漏的缘故。
11、对限压式变量液压泵，当压力调节螺钉未调好，**过限压压力后，显著减小，进入系统后，压力难以更高。
12、液压泵内零件磨损后，在低温时虽可升压，但设备运转一段时间后，油温升高，因磨损产生的内泄漏大，压力损失也大，压力此时便上不去（不能到），如果此时想硬性调整上去（旋紧溢流阀），会产生表针剧烈抖动的现象。此时可以肯定是液压泵内严重磨损，如果换一台新的液压泵，压力马上会上去。
13、定子内表面刮伤，致使叶片**部与定子内曲面接触不良，内泄漏大，减小，压力难以调上去。此时应抛光定子内曲线表面或者更换定子。
14、对装有减压阀的中高压液压泵，如果减压阀的输出压力调的太高，会导致叶片**部与定子内表面因接触应力过大而早期磨损。使液压泵内泄漏大，输出减小，压力也上不去。
除了容积式泵的一般特性之外，液压泵还具有以下特征。
1.相对均匀，运行稳定，噪音小。
2.双作用液压泵采用径向力平衡，轴承寿命长，内部密封性好，容积效率高，可用于高压应用。通常，液压泵的额定工作压力不**过7MPa，高压液压泵可达到14-21MPa。
3.结构紧凑，体积小，大。
4.单作用液压泵可实现可变方向可变调节。
5.工作条件更加严格。由于叶片的抗冲击性差和易堵塞，它对油的清洁度和粘度敏感。还必须正确配置端部间隙或滑槽间隙。另外，当旋转速度太低时，叶片可能由于离心力不足而不能按压定子表面，并且如果太高，则可能发生空化。一般液压泵的速度约为500~2000r/min。
6.结构更复杂，零件的制造精度更高。
在船舶中，液压泵通常用作液压系统中的工作油泵或用作低粘度清洁油的泵。
