液压油

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：

90220: 矿物油及相关烃类液压油

90221: 环境友好型液压油

使用环境友好型液压油时，请咨询我们。

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

Pressure at working port A or B			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		2.5 s
Total operating period		300 h
Minimum pressure (high-pressure side)	p_HP min	10 bar	Minimum pressure on high- or low-pressure side (port A or B) required to prevent damage to the axial piston unit.
Minimum pressure (low-pressure side)	p_LP min	see diagram "Permissible rotational speed in relation to outlet pressure"
Rate of pressure change			Definition
Rate of pressure change	R_A max	16000 bar/s	Maximum permissible rate of pressure build-up and reduction during a pressure change over the entire pressure range.
Case pressure at port L			Definition
Motor operation mode	p_L max	4 bar absolute	Maximum permissible case pressure measured at port L or L₁
Pump operating mode	p_L max	2 bar absolute	Maximum permissible case pressure measured at port L or L₁
