单螺杆泵中的转子螺杆及定子螺腔均属复杂螺旋体,加工工艺较为复杂。今分述如下: 一、转子螺杆的加工转子螺杆(见图1)的几何形状是由偏心圆D围绕转子中心线作螺旋运动而形或的螺旋体。以转子的中心线为中心,以转子中心线到偏心圆D中心的距离e Single screw pump rotor screw and stator screw cavity are complex spiral body, the processing technology is more complicated. The points are as follows: First, the rotor screw machining Rotor screw (see Figure 1) is the eccentric geometry of the circle around the center of the rotor spiral or helical shape. The center of the rotor as the center line, with the rotor center line to the center of eccentric circle distance e
