(RA7VO)進口軸向柱塞變量泵 產品特點 Product features

斜軸結構軸向錐形柱塞變量泵，用于開式回路靜液壓傳動 Axial tapered piston variable displacement pump with inclined shaft structure is used for open circuit hydrostatic transmission

輸出流量與轉速和泵排量成正比，流量從最大到零（qvmax到qvin=0）無級可調  The output flow is proportional to the speed and pump displacement, and the flow is stepless adjustable from maximum to zero (qvmax to qvin=0)

多種變量方式適用于各種調節和控制裝置 Various variable modes are applicable to various adjustment and control devices

開式回路，堅固緊湊的軸承系統，壽命長 Open circuit, solid and compact bearing system, long service life

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
