Therefore vane pump for knowledge and necessary, especially for the work in hydraulic related more appear particularly important. This article has been widely applied in modern-day vane pump as the foundation, based on quantitative vane pump is double-acting vane pump design. In the design process of vane pump adopt some new technology and new ideas, and used in the design of vane pump. Design of double-acting vane pump of the blade angle is discussed, and the comparison of two kinds of views chooses now has more and more widely recognized blade angle equal to zero point of view. In the design of the stator transition curve and there are no adopts traditional Constant acceleration-such as deceleration curve or Archimedes spiral curve, but a combination of the fact that the current popularity of CNC machine tools, selection of high-order curve is used as the basis of the stator design of the transition curve. Also main reference the YB1 series vane pumps related products structure and tec
