(RA11VO、RA11VLO)进口开式回路变量柱塞泵产品特点 Product features

斜盘式轴向柱塞变量泵，用于开式回路液压传动 Swashplate axial piston variable displacement pump for open circuit hydraulic transmission

泵在自吸条件下，油箱加压或带内置升压泵（离心泵）的条件下工作 The pump works under the condition of self-priming, oil tank pressurization or with built-in booster pump (centrifugal pump)

多种控制，满足不同的操作要求 Multiple controls to meet different operating requirements

即使泵在运行时也可在外部来调节功率控制 The power control can be adjusted externally even when the pump is running

带有通轴驱动，可承装齿轮泵或直到相同规格的轴向柱塞泵（100%通轴驱动）With through shaft drive, gear pump or axial piston pump of the same specification can be installed (100% through shaft drive)

输出流量与驱动转速成比例，并可在最大值与零值之间无级变化 The output flow is proportional to the driving speed and can change steplessly between the maximum value and zero value

工作粘度范围 Working viscosity range

为了获得最佳效率和使用寿命，RETZ推荐工作粘度（在工作温度下）在下列范围内选择∶v opt=最佳工作粘度16..36mm2/s

In order to obtain the best efficiency and service life, Retz recommends that the working viscosity (at the working temperature) be selected in the following range: V opt= the best working viscosity 16 36mm2/s

油液的过滤 Filtration of oil

液压油过滤越干净，油液清洁度等级越高，轴向柱塞元件的寿命越长 The cleaner the hydraulic oil is filtered, the higher the cleanliness level of the oil is, and the longer the service life of the axial piston element is

为保证轴向柱塞元件的功能，需要清洁度至少为 按ISO4406的20/18/15级最低的清洁度等级为 In order to ensure the function of the axial piston element, the cleanliness is required to be at least: according to ISO4406 level 20/18/15, the minimum cleanliness level is

液压油处于高温时（90℃至最高115℃），按ISO4406的19/17/14级  When the hydraulic oil is at high temperature (90 ℃ to 115 ℃ at most), it shall be subject to grade 19/17/14 of ISO4406
