双作用吐泵
基本介绍:转子转-圈，每个密封容积变化两个循环，所以密封容积每圈内完成吸油、压油各两次，故称为双作用泵。相比于单作用泵，是变量泵，双作用泵是定量泵。又因泵的两个吸油窗口与两个压油窗口是径向对称的，作用于转子上的液压力是平衡的，以又称为平衡式叶片泵
优点:
①双作用使排量增加一倍，流量也相应增加。
②吸压、油口对称于旋转中心配置，旋转轴上受到的液压力是平衡的，
③轴和轴承上无径向载荷，有利于提高泵的工作压力。

结构
双作用式叶片泵是由定子、转子、叶片、配流盘和泵体组成，转子与定子同心安装，定子的内曲线是由两段长半径圆弧、两段短半径圆弧和四段过度曲线所组成，共有八段曲线。

工作原理
转子做顺时针旋转，叶片在离心力作用下径向伸出，其顶部在定子内曲线上滑动。此时，由两叶片、转子外圆、定子内曲线及两侧配有盘所组成的密闭的工作腔的容积在不断地变化，在经过右下角以及左上角的配油窗口处时，叶片伸出，工作腔容积增加，形成真空，油液通过吸油窗吸入;在经过右_上角及左下角的配油窗口处时，叶片回缩，工作腔容积变小，压强增大，液压缸油液通过液压窗口输出。

双作用叶片泵的困油现象
当相邻两叶片同时位于吸排口之间时，正好将吸排口隔开，这时就形成封油区，就可能出现困油问题。(旋转时两叶片间容量不变，虽不会发生困油，但从吸过渡到排，会产生压力冲击;叶片包角太小，产生困油，包角太大，吸排窗口沟通，工作失常。)解决方法配流盘的压油窗口的一端开三角卸荷槽(减少过渡的压力冲击、脉动、噪声;消除困油)。

性能特点
叶片泵压力脉动小，因磨损而产生的工作压力下降车小运转平稳、噪音较小，结构紧凑，起动转矩小。但吸人条件较差，运动部件的工作可靠性较低。
1.流量较均匀，运转平稳，噪声较低。
2.双作用叶片泵转子所受径向力是平衡的，轴承寿命长;它的内部密封性也较好，容积效率较高;因此，一般额定排出压力较高，可达7MPa左右。
3.结构紧凑，尺寸较小而流量较大。
4.对工作条件要求较严。叶片抗冲击较差，较容易卡住，对油液的清洁程度和粘度都比较敏感。端面间隙或叶槽间隙不合适都会影响正常工作。转速一-般在500~2000r /道范围内，太低则叶片可能因离心力不够而不能压紧在定了表面，而太高则吸人时会产生“气穴现象”；
5.结构较复杂，零件制造精度要求较高。

液压控制 液压控制用油液作为工作介质，故能把由于功率的损耗而产生的热量，从发生的地方带到别处，这样在一定的功率情况下，可以大大减小部件的尺寸；从负载的影响看，液压系统具有机械上的刚性，用在闭环系统中，定位刚度较大，位置误差较小；与机械机构相比，液压执行器的响应速度较高，能高速启动、制动与反向，同时其力矩—惯量比也较大，因而其加速能力较强；液压传动易实现无级调速，具有自身润滑等优点。
液压系统的缺点是：由于难以避免漏油，因而会影响运动的平稳性，并使效率降低；油液被尘埃或流体截止中其他杂质污损后，会造成液控系统发生故障；油液具有易燃性，有引起爆炸的危险；液体粘度受温度影响，使供油量和执行机构的运动速度不稳定；油液中有空气会引起工作机构的不均匀跳动；就处理小功率信号的数学运算、误差检测、放大、测试与补偿等功能而言，液压装置不如电子或机电装置那样灵活、线性、准确和方便，因而在控制系统的小功率部分，一般不宜采用，主要应用于系统的动力部分。
