3D oblikovanje i proračun kućišta vijčane pumpe
Get PDFShown 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.Prikazano je 3D oblikovanje i proračun kućišta trovretene vijčane pumpe na temelju postojeće 2D radioničke dokumentacije u lijevanoj izvedbi. Izrađen je kontrolni proračun debljine stjenke kućišta trovretene vijčane pumpe za materijale SL–25, NL–42, AlSiMg i ispitni tlak 1,5 MPa (15 bara). Svi 3D modeli pozicija, sklop i ˝generirana˝ 2D radionička dokumentacija izrađeni su u programskom alatu SolidWorks naprednim tehnikama 3D oblikovanja. U programskom modulu Solidworks Simulation provedene su analize naprezanja kućišta trovretene vijčane pumpe Finite Element Analysis – FEA za materijale: SL–25 , NL–42 i AlSiMg koje su potvrdile točnost provedenog kontrolnog proračuna, te analiza toka strujanja fluida u 3 modelu sklopa trovretene vijčane pumpe. Pomoću 3D pisača MakerBot Replicator 2X primjenom FDM tehnologije taložnog očvršćivanja materijala izrađen je umanjeni 3D model sklopa trovretene vijčane pumpe. Istaknuta je praktična primjenjivost unapređenja i razvoja vijčanih pumpi
