Problems solved by technology

[0003] When the screw pump is working, there will be friction between the rotor and the stator, which will generate a lot of heat. At present, the stator of the screw pump generally adopts the structure of a metal shell and a non-metallic inner cylinder, which has poor thermal conduc

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...

Abstract

The invention discloses a safety screw pump, which includes a pump body; the rotor of the pump body includes a skeleton and a non-metallic layer coated and fixed on the outside of the skeleton; the skeleton and the stator of the pump body are made of metal materials; The invented safe screw pump has good thermal conductivity, which is good for heat dissipation, reduces the working temperature of the pump body, ensures the matching accuracy and performance of each component, and prolongs the service life; reduces the wear between the rotor and the stator of the screw pump, and at the same time avoids contact with the stator. Sparks can be generated between them, which can be used to transport flammable materials, increase the scope of application, and create conditions for the use of metal materials to make stators, which is conducive to the safe and stable operation of screw pumps.
