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:
HLP 32,温度为 73°C
HLP 46,温度为 85°C
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 |

轴封寿命受轴向柱塞单元转速和壳体压力影响。
壳体与环境之间的平均压差增加,或压力峰值出现频率升高时,使用寿命会缩短。

调试和运行期间,轴向柱塞单元必须充满液压油并排尽空气。长时间停机期间也必须注意这一点,因为单元内的油液可能经液压管路自行排空。
尤其在“传动轴朝上”的安装位置,必须确保完全充油并排尽空气,否则例如可能存在干运转风险。
壳体区域的泄漏油必须经位置最高的泄油口(T 1、T 2)排至油箱。
多个单元共用一条泄油管路时,必须确保不超过各单元相应的壳体压力。共用泄油管路的尺寸必须保证,在任何运行状态下,尤其是冷启动时,所有连接单元的最大允许壳体压力均不会被超过。如果无法满足,必要时必须铺设独立的泄油管路。
为获得较低的噪声,应使用弹性元件将所有连接管路解耦,并避免采用油箱上方安装。
在任何运行状态下,回油管路都必须接入油箱最低液面以下。
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。

轴向柱塞单元设计用于开式和闭式回路。
轴向柱塞单元的项目规划、安装和调试,必须由具备资质的专业人员参与。
使用轴向柱塞单元前,请完整、仔细地阅读相应操作手册。必要时可向 Bosch Rexroth 索取。
最终确定设计前,请索取具有约束力的安装图。
必须遵守规定的数据及说明。
防锈保护:我们的轴向柱塞单元标准供货时,提供最长 12 个月的防锈保护。如需更长的保护时间,最长可达 24 个月,请在订购时以文字注明。上述保护时间仅适用于最佳储存条件;相关条件的详细说明参见数据表 90312 或操作手册。
并非该产品的所有版本都获准用于符合 ISO 13849 的安全功能。如果您需要功能安全相关的可靠性参数,例如 MTTF D,请咨询 Bosch Rexroth 的相应联系人。
液压系统中必须设置溢流阀。
必须遵守操作手册中有关连接螺纹及其他螺纹接头拧紧力矩的说明。
必须遵守操作手册中有关油口螺纹及其他螺纹连接拧紧力矩的规定。
油口和安装螺纹按允许的最大压力 p max 设计,参见操作手册。机器或系统制造商必须确保连接元件及管路,在必要安全系数下满足规定的运行条件,包括压力、流量、液压油及温度。
工作油口和功能油口仅用于连接液压管路。
