“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.结构复杂,零件的制造精度高。
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。
