In order to find out the advantages and shortcomings of two line types of three-thread single-screw pump, the comparative analysis method is initially used on the same kind screw pump of different line types .By using ANSYS,this paper adopted the finite element analysis to analyze the deformation、stress and strain of outer equidistant curve of curtate hypocycloid and inner equidistant curve of curtate epicycloids two line types three-thread single-screw pump under uniform pressure and 1MPa differential pressure .It focuses on discussing over the rubber stator of screw pump suffers influenced by the above three factors. The result shows that the existence of uniform pressure makes an uniform radial displacement of the rubber stator; the 1MPa differential pressure makes a great deformation of the rubber stator and the value of stress and strain also increases accordingly, by comparative analysis of two line types of three-thread single-pump, the sealing property of outer equidistant curve of curtate hypocycloid three-thread single-screw pump takes more advantages rather than inner equidistant curve of curtate epicycloids three-thread single-screw pump.
