Embodiment Construction
[0021] Such as figure 1 , 2 As shown, the twin-stator single-rotor screw motor homogeneous pump in this scheme includes the outer stator 1 on the outer layer, the rotor 2 in the middle and the inner stator 3 in the center. The inner surface of the outer stator 1 is an inner spiral made of rubber, and the inner stator 3 The surface of rotor 2 is an outer helix, the outer surface of the rotor 2 is an outer helix, and the inner surface is an inner helix. Among them, the number of inner spiral heads is one more than the number of outer spiral heads, that is, the number of inner spiral heads in outer stator 1 is one more than the number of outer spiral heads in rotor 2, and the number of inner spiral heads in rotor 2 is one more than the number of outer spiral heads in inner stator 3. . In this scheme, the ratio of the number of screw heads in contact with the outer stator 1 and the rotor 2 is 8:7, and the ratio of the number of screw heads in contact with the rotor 2 and the inn...
