以上为德国力士乐A10VSO型号 (31和52系列)无通轴型柱塞泵10、18、28、45、71、100、140各排量常规型号。
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。
❸变量活塞精度不好，配合间隙过大或过小使变量活塞移动不灵活，卡住时，使变量活塞不动，不卡住时，变量活塞来一个跳动，导致泵排量跳动。8.1.7蓄能器供油回路
现代液压设备朝高压、高速的方向发展，有些液压设备，如压铸机等在短时间需要很大的液压功率。为了避免使用特大功率的电机和泵，采用著能器回路，用蓄能器集聚的能量补充高速高压的压射过程(短时间)的能量，这样便可不用最大的电机和泵实现压铸机只有某工序才会用到的超过泵功率工况的能量补充，使泵功率损失减小。它也是种高效率液压回路，是液压设备采用的节能東源回路之- .此处仅举图821所示的例子。
在循环动作的间隙中，系统不需要供给能量时，电磁阀3断电，泵以溢流阀2调节的压力向蓄能器供油。当蓄能完毕，压力开高，压力继电器6发信号，电磁阀3通电;液压泵1卸荷，单向阀4关闭，防止蓄能器6及系统的高压油反灌。
进、出油方向，达到控制执行元件的运动状态(运动或停止)和运动方向的改变(前进或后退，上升或下降)的液压回路，称为方向控制回路。 [I额21(1)方向控制回路
①靠重量回程的方向控制回路依靠压力油而使液压缸上升，靠液压缸活塞本身的重量回程。如图8-22(a) 所示的回路中，当三位三通阀3处于中位，泵1卸荷;阀3处于左位，缸4上升;阀3右位，靠重力使缸4下降。
②靠弹簧返程的回路 如图8-22(b)所示，当1DT通电，压力油进人缸4左腔，使其活塞前进(右行);换向时，1DT断电，缸4左腔通油池，靠液压缸本身的弹簧力使液压缸活塞后退(左行)。 IS响站]
③用正、反转泵构成的换向回路如图8-22 (c)所示，这种回路采用闭式回路。货当双向泵3正转，压力油进人缸6左腔，推动活塞前进，缸右腔通过液控单向阀5回油;反之，当泵3反转，缸6后退。其工作压 力分别由溢流阀1和2调节。
