Abstract

With the continuous development of industrial technology, a variety of liquid transportation is particularly important, and the single-screw pump, a tool of fluid transmission, becomes also critical. Higher requirements are made to meet the demand of the industrial development on the single-screw pump, and some certain industries with a single-screw pump are under terrible conditions. It shows that researching and developing the single-screw pump of good performance will bring a broad social and economic benefits. To meet the better needs of specific working conditions, this paper explains clearly the working principle and structural features of single-screw pump, and designs and selects the appropriate single-screw pump parameters by a given flow and pressure on the basis of the traditional theoretical system and using of existing design methods and tools. So that the structural design calculations, key performance computing and influencing factors analysis are completed. After that, we establish an effective single-screw pump three-dimensional model by using of three-dimensional modeling for the simple kinematics simulation on the single-screw pump designed, the results show that it can provide a reference for single-screw pump performance improvement.
