(RPV2R)高压定量叶片泵

(RPV2R)进口高压定量叶片泵 性能 performance

1、设计合理、加工精密的圆弧叶片，降低了叶片对定子内曲线的压应力，提高了定子和叶片的使用寿命 The arc blade with reasonable design and precise machining reduces the pressure stress of the blade on the inner curve of the stator and improves the service life of the stator and blade

2、定子采用先进的高次方无冲击过渡曲线，使叶片具有良好的运动和受力状态，保证了叶片与定子间的良好接触，并使得流量损失、压力和流量脉动为最小，噪声更低、寿命更长retz品牌 The stator adopts advanced high-power non impact transition curve, which makes the blade have good movement and stress state, ensures good contact between the blade and the stator, minimizes flow loss, pressure and flow pulsation, and has lower noise and longer service life

3、侧板采用液压平衡，可获得更好的容积效率  The side plate is hydraulically balanced to obtain better volumetric efficiency

4、关键零件选用优质的材料和先进的热处理工艺，油泵整体可靠性进一步提高 The key parts are made of high-quality materials and advanced heat treatment technology, and the overall reliability of the oil pump is further improved

5、采用插装式结构，主要内脏零件做成组件形式，泵芯更换可在几分钟内完成，互换性好，维修方便 The plug-in structure is adopted, and the main internal parts are made into components. The replacement of the pump core can be completed in a few minutes, with good interchangeability and convenient maintenance

RPV2R高压定量叶片泵 参数表  Parameter table

抗磨液压油粘度20cSt（ISOVG32油，油温度50℃），转速150r/min，进口压力0MPa Anti wear hydraulic oil viscosity 20cst (isovg32 oil, oil temperature 50 ℃), rotating speed 150r/min, inlet pressure 0mpa

说明

1、公称排量“6”、“8”泵，当压力高于16MPa时应增大转速高于1450r/min，而公称排量“31”、“116”泵，最高工作压力应限在16MPa以内 For pumps with nominal displacement of "6" and "8", when the pressure is higher than 16MPa, the speed should be increased to higher than 1450r/min, while for pumps with nominal displacement of "31" and "116", the maximum working pressure should be limited to 16MPa

2、使用含水液压液、合成液压液时，油泵的额定压力和最高转速应有限制 When using aqueous hydraulic fluid and synthetic hydraulic fluid, the rated pressure and maximum speed of the oil pump shall be limited

3、低速起动时油液的最大粘度应有限制 The maximum viscosity of oil during low-speed starting shall be limited

4、Pn-指（使用抗磨液压油时）额定压力 PN refers to the rated pressure (when anti-wear hydraulic oil is used)

5、当工作转速n≠1500r/min时，输出流量，驱动功率可按近似公式∶"表中值×n/1500"计算得出其近似值  When the working speed n ≠ 1500r/min, the output flow and driving power can be calculated according to the approximate formula: "table median value" × N/1500 "calculate its approximate value
