A10VSO10DR/52R-PSC64N00-SO922

   图&20(b)为电液比例变量泵泵源回路图。如果不采用比例电磁铁， 而采用改变外控压力X大小(例如取负载压力)，也可进行变量控制[图8-20(c) ]。

      德国力士乐公司生产的ATV系列电液比例变系就是采用这种变量机构进行比例变量的。

    (2)故障分析及排除

      [故障1]大小排量之间切换不良

      泵能满足小排量区段工作，却到不了大排量工作段:或者到了大排位工作段，就再也回不到小排量的工作段:或者系的特性曲线不成线性:或者原不能停留在曲线的某一点，特性由线屋铝齿状。产生原因和排除方法如下。

      ①调压弹簧2与反馈弹费的刚度不匹配，应使之匹配。一般， 调压弹赞和反馈弹簧的刚度比应为10: 1左右。

      ②弹簧精度差。作为比例泵的调压弹黄和反馈弹赞须用高精度弹簧。[故障21在整个变量过程中出现排 量阶跃突变

      这一故障现象是指变量时不能稳定在某一变量点工作， 使调节曲线产生振荡。故障产生原因和排除方法如下。

      ①控制阀的配合间隙不好，间隙过大，加上精度不好，阀在工作中易产生泄漏，从而导致变量活塞跳跃而产生排量跳跃;配合闻除过小或因污物，使控制阀阀芯存在卡阻现象，卡住时，无法去操控变量活塞移动:控制阀阀芯不卡住时，操控变量活塞来一个跳动，导致泵排量跳动。

      ②污物进人控制阀，卡住控制阀芯，产生类似现象。
