Rexroth柱塞泵的优点
1. 参数高:额定压力高，转速高，力士乐油泵的驱动功率大
2. 效率高，容积效率为95%左右，总效率为90%左右
3. 寿命长
4. 变量方便，形式多
5. 单位功率的重量轻
6. 力士乐柱塞泵主要零件均受压应力，材料强度性能可得以充分利用
用途
Rexroth 柱塞泵被广泛用于高压、大流量、大功率的系统中和流量需要调节的场合，如龙门刨床、拉床、液压机、工程机械等得到广泛的应用。
1.Rexroth柱塞泵的形式很多。
2.Rexroth柱塞泵按柱塞的排列和运动方向不同，可分为Rexroth径向柱塞泵和Rexroth轴向柱塞泵。
3.Rexroth柱塞泵按配流方式的不同，可分为斜盘式(直轴式)和斜轴式。
德国力士乐变量柱塞泵有开槽控制的斜盘设计，连续可变的排量，良好的自吸性，允许连续工作压力达到350bar，低噪音，使用寿命长，驱动轴能吸收轴向和径向载荷，模块化设计，通轴驱动控制时间短，可实现多回路系统。可选择不同的泵位置，安装位置也可选择，可在降低的工作参数下用HFC液工作。
力士乐A11VO变量柱塞泵压力控制、流量控制、恒功率控制、交叉总功率控制、半交叉功率控制、腹肌功率越权控制、正极功率越权控制、电子越权控制等变量原理图文详解。
力士乐柱塞泵A11VO系列特性：
1. 斜盘结构轴向柱塞变量泵用于开式回路液压传动；
2. 主要应用于混凝土泵车 铲运机械、混凝土机械、路面机械、压实机械及起重机械等工程机械领域；
3. 泵在自吸条件下，油箱加压或带升压泵（离心泵）工作；
4. 可提供多种变量机构用于不同的控制和调节功能；
5. 即使机器运行时也可经外部来设定功率控制；
6. 该泵可带有通轴驱动以承装齿轮泵或直到相同规格的轴向柱塞泵（通轴驱
动）；
