最低吸油压力 pS 最小 __________________0.8 bar（绝对）
最高吸油压力 pS 最 高 __________________ 30 bar（绝对）
最小压力（入口）
为了避免轴向柱塞单元损坏，吸油口 S（入口）处必须保证
为最小压力。最小压力取决于轴向柱塞单元的速度和排量。
入口压力 p绝对 [bar]
速度 n no 最 高
排量 V Vg
g 最 高
入口压力为静态供油压力或升压的最小动态值。
请注意：

适用于外部激励（例如，柴油发动机 2 - 8 倍旋转频率，万向轴 2 倍旋转频率）。
– 限值仅对单极泵有效。
– 必须考虑连接部件的负载能力。
注意事项
超过允许的最 高值或低于允许的最小值可能会导致功能丧失，运行使用寿命缩短或轴向柱塞单元彻底损坏。
可以通过计算确定允许值。
确定泵的规格
流量 qV = Vg ? n ? hV [l/min] Vg = 每转的几何排量（单位为 cm3）
1000 Dp = 压差（单位为bar）
驱动扭矩 T = Vg ? Dp [Nm] n = 速度（单位为 rpm）
20 ? p ? hmh hV = 容积效率
功率 P = 2p ? T ? n = qV ? Dp [kW] hmh = 机械 - 液压效率
60000 600 ? ht ht = 总效率（ ht = hV ? hmh）

柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。机械分类 ? 轴向式 ? 直轴斜盘式  ? 径向式 ? 液压式 柱塞泵一般分为单柱塞泵、卧式柱塞泵、轴向柱塞泵和径向柱塞泵。
