Confirms the flow area, the minimum value of the comparative slide velocity of the floating contact point, the maximum integration curvature and the radius variation ratio as the performance indexes of PCP, discussed how the PCP’s structure parameters influence the performance indexes. Discovered that the minimum value of the comparative slide velocity of the floating contact point is proportional to the number of rotor’s threads and the coefficient of isometric radius, but is inversely proportional to the radius variation ratio; From the perspective of increasing the minimum value of the comparative slide velocity of the floating contact point, large number of rotor’s threads, big coefficient of isometric radius and little radius variation ratio is needed. But amplify the number of rotor’s threads, the coefficient of isometric radius and decrease the radius variation ratio will reduce the flow area. And amplify the number of rotor’s threads will make the maximum integration curvature greater; decrease the radius variation ratio will reduce the maximum integration curvature too. These four indexes are in contradiction to each other, structure parameters cannot make all performance indexes are optimal.
