Embodiment Construction
[0011] figure 1 It is a schematic structural diagram of the present invention, as shown in the figure: the safety screw pump of this embodiment includes a pump body 1; the rotor 2 of the pump body 1 includes a skeleton 3 and a non-metallic layer 4 coated and fixed on the outside of the skeleton 3; The skeleton 3 and the stator 5 of the pump body 1 are all made of metal materials; the stator 5 has good thermal conductivity, which is beneficial to heat dissipation, can reduce the working temperature of the pump body 1, ensures the matching accuracy and performance of each component, and prolongs the service life; The outer circular surface of the stator 5 is provided with annular fins arranged along the circumferential direction, and the annular fins are multiple and uniformly arranged along the axial direction of the stator 5. The heat dissipation plate and the annular fins are intersected and fixed into a net shape, and the annular fins and the longitudinal heat dissipation pl...
