Sažetak

Shown is the 3D design and calculation of a three-spindle screw pump housing based on existing 2D workshop documentation of a cast version of the housing construction. A control calculation of the thickness of the wall of the housing of the three-spindle screw pump has been made for materials SL–25, NL–42, AlSiMg and test pressure of 1,5 MPa (15 bars). Each 3D model of positions, assemblies and generated 2D workshop documentation are made in the software tool SolidWorks with advanced techniques of 3D modelling. In the software module SolidWorks Simulation stress analysis of the housing of a three-spindle screw pump was performed, that is, Finite Element Analysis – FEA for materials SL–25 , NL–42 and AlSiMg, that confirmed the accuracy of the calculations made, and the analysis of the fluid flow of the 3D model of the assembly of the three-spindle screw pump. With help of the 3D printer MakerBot Replicator 2X with application of FDM technology of sedimentary hardening of materials, a miniature 3D model of the assembly of the three-spindle screw pump was created. The practical application of the improvement and development of screw pumps is emphasized.
