液压油选择

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：

90245: Bosch Rexroth 液压元件（泵和马达）的液压油评级清单

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)。

选择图

液压油过滤

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

工作压力范围

Pressure at working port A or B (high-pressure side)			Definition
Nominal pressure	p_nom	see table of values	The nominal pressure corresponds to the maximum design pressure.
Maximum pressure	p_max	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

Pressure at suction port S (inlet)			Definition
Minimum pressure	p_s min	0.8 bar absolute	Minimum pressure at inlet (suction port S) that is required to avoid damage to the axial piston unit. The minimum required pressure is dependent on the speed of the axial piston unit. (see diagram "Maximum speed")
Maximum pressure	p_s max	30 bar absolute
Case pressure at port T			Definition
Continuous differential pressure	Δp_T _cont	2 bar	Maximum averaged differential pressure at the shaft seal (case to ambient)
Maximum differential pressure	Δp_T _max	see diagram "Maximum differential pressure at the shaft seal"	Intermittent differential pressure at the shaft seal (permitted at reduced speed)

注意

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。

壳体压力必须等于或高于环境压力。

一般信息

所列数值为最大参数，不允许用于连续运行。

应避免作用方向为 -F ax 的轴向力，否则会缩短轴承寿命。

通过传动带输出动力时，需要满足特殊条件。请咨询我们。

规格 250 ... 1000 的说明：

存在径向力时，适用受限制的性能参数。请联系我们。

若单元运行时存在轴向力，请联系我们。

径向力 F q 对轴承寿命的影响

选择合适的径向力 F q 方向，可减小内部旋转组件作用力对轴承产生的载荷，从而优化轴承寿命。配对齿轮的推荐安装位置取决于旋转方向。示例：

安装说明

概述

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。较长时间停机后也必须注意这一点，因为单元内的油液可能经液压管路流回油箱。

尤其在“传动轴朝上”的安装位置，必须完全充油并排尽空气，否则例如存在干运转的危险。

壳体内的泄油必须经位置最高的可用泄油口（T 1、T 2）引至油箱。

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，在任何运行条件下，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，必须根据需要敷设独立的回油管路。

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。

在任何运行条件下，吸油管路与泄油管路都必须接入油箱最低液面以下。允许吸油高度 h S 取决于总压力损失，但不得高于 h S max = 800 mm。在运行和冷启动期间，油口 S 的最低吸油压力也不得低于 0,8 bar（绝对压力）。

设计油箱时，应确保吸油管与泄油管之间有足够间距，以便油液减速和脱气，并防止较热的回油被直接吸回吸油管。

安装位置

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。

油箱下方安装（标准）

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。

Installation position	Air bleeding	Filling
1	\u2012	T₁
2	\u2012	T₂
3	\u2012	T₁
4	R (U)	T₂

油箱上方安装

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。

Installation position	Air bleeding	Filling
5	F	T₁ (F)
6	F	T₂ (F)
7	F	T₁ (F)
8	R (U)	T₂ (F)

Key
F	Filling / Air bleeding
R	Air bleed port
U	Bearing flushing / air bleed port
S	Suction port
T₁, T₂	Drain port
h_t min	Minimum required immersion depth (200 mm)
h_min	Minimum required spacing to reservoir bottom (100 mm)
SB	Baffle (baffle plate)
h_S max	Maximum permissible suction height (800 mm)

Note: Connection F is part of the external piping and must be provided on the customer side to simplify the filling and bleeding.

注意

接口 F 属于外部管路的一部分，必须由客户设置，以便简化充油与排气。

一般项目规划说明

轴向柱塞单元设计用于开式回路。

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。

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。
