(RA11VO、RA11VLO)進口開式回路變量柱塞泵產品特點 Product features

斜盤式軸向柱塞變量泵，用于開式回路液壓傳動 Swashplate axial piston variable displacement pump for open circuit hydraulic transmission

泵在自吸條件下，油箱加壓或帶內置升壓泵（離心泵）的條件下工作 The pump works under the condition of self-priming, oil tank pressurization or with built-in booster pump (centrifugal pump)

多種控制，滿足不同的操作要求 Multiple controls to meet different operating requirements

即使泵在運行時也可在外部來調節功率控制 The power control can be adjusted externally even when the pump is running

帶有通軸驅動，可承裝齒輪泵或直到相同規格的軸向柱塞泵（100%通軸驅動）With through shaft drive, gear pump or axial piston pump of the same specification can be installed (100% through shaft drive)

輸出流量與驅動轉速成比例，并可在最大值與零值之間無級變化 The output flow is proportional to the driving speed and can change steplessly between the maximum value and zero value

工作粘度范圍 Working viscosity range

為了獲得最佳效率和使用壽命，RETZ推薦工作粘度（在工作溫度下）在下列范圍內選擇∶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

油液的過濾 Filtration of oil

液壓油過濾越干凈，油液清潔度等級越高，軸向柱塞元件的壽命越長 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

為保證軸向柱塞元件的功能，需要清潔度至少為 按ISO4406的20/18/15級最低的清潔度等級為 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

液壓油處于高溫時（90℃至最高115℃），按ISO4406的19/17/14級  When the hydraulic oil is at high temperature (90 ℃ to 115 ℃ at most), it shall be subject to grade 19/17/14 of ISO4406
