[0002] As the name implies, a three-impeller rotor refers to a rotor with three blades (or impellers). This design enables the rotor to push the fluid more effectively during rotation, achieving functions such as gas compression and transportation. Three-impeller rotors are widely used in fluid machinery such as Roots blowers, Roots pumps, and vacuum pumps. When the three-impeller rotor is processed by a CNC lathe, it needs to be clamped and positioned. Due to the long rotor and its special shape, there are certain difficulties in clamping and fixing. When positioning the rotor, it is usually positioned manually. This traditional positioning method is inaccurate and wastes labor.
