轴向柱塞单元设计用于符合 DIN 51524 的 HLP 矿物油。
开始项目规划之前,应查阅以下数据表,了解液压油的应用说明与要求:

为降低轴向柱塞单元中液压油的高温,建议使用冲洗补油压力阀(见“扩展功能和型号”章节)。
Bosch Rexroth 按技术数据表 90235 中的液压油评级方法评估液压油。
以下技术数据表列出了在液压油评级中获得正面评价的液压油:
选择液压油时,应使工作温度范围内的工作黏度处于最佳范围 (ν opt;见选择图)。
更精细的过滤可提高液压油清洁度,从而延长轴向柱塞单元的寿命。
应按 ISO 4406 保持至少 20/18/15 的清洁度等级。
当泄油口处液压油黏度低于 10 mm²/s 时(例如高温短时运行),要求按 ISO 4406 达到至少 19/17/14 的清洁度等级。
例如,在以下情况下,黏度为 10 mm²/s:
Pressure at working port A or B (high-pressure side) | Definition | ||
Nominal pressure | pnom | see table of values | The nominal pressure corresponds to the maximum design pressure. |
Maximum pressure | pmax | see table of values | The maximum pressure corresponds to the maximum operating pressure within the single operating period. The sum of the single operating periods must not exceed the total operating period. |
Single operating period | 10 s | ||
Total operating period | 300 h | ||
Minimum pressure | pHP min | 25 bar | Minimum pressure on high-pressure side (port A or B) required to prevent damage to the axial piston unit. |
Minimum pressure at inlet (pump operating mode) | pE min | see diagram | To prevent damage to the axial piston motor in pump mode (change of high-pressure side with unchanged direction of rotation, e.g. when braking),a minimum pressure must be guaranteed at the working port (inlet). The minimum pressure depends on the rotational speed and displacement of the axial piston unit. |
Total pressure | pSu | 700 bar | The summation pressure is the sum of the pressures at both work ports (A and B). |
Rate of pressure change | Definition | ||
with integrated pressure relief valve | RA max | 9000 bar/s | Maximum permissible rate of pressure build-up and reduction during a pressure change over the entire pressure range. |
without pressure relief valve | RA max | 16000 bar/s | |
Case pressure at port T | Definition | ||
Continuous differential pressure | ΔpT cont | 2 bar | Maximum averaged differential pressure at the shaft seal (case to ambient) |
Pressure peaks | pT peak | 10 bar | t < 0.1 s |
本图仅适用于最佳黏度范围 v opt = 16 至 36 mm 2 /sec..

参见下列示例 1 至 8。
其他安装位置可按要求提供。建议安装位置:1 和 2。
注意
安装位置 4 和 8,即“轴朝上”时,需要设置排气口 R(订购时请以文字注明,特殊版本)。
油箱下方安装,是指轴向柱塞单元安装在油箱外部、最低液面以下。
油箱上方安装,是指轴向柱塞单元安装在油箱最低液面以上。
安装位置 8(传动轴朝上)的建议:在泄油管路中设置单向阀,开启压力为 0,5 bar,可防止泵壳内油液排空。
