Tiivistelmä
This thesis seeks to relieve the critical demand for cleaning filter systems (such as in power generation, desalination, chemical processing) by introducing a verification of a high-pressure backwash pump.
With the objective of achieving such device structural stability, this thesis explore the operating systems of pump operating in such harsh conditions. It verified the strength and stiffness of both pump body and its integral linking parts through three-dimensional simulation/part disassembly simulation in SolidWorks and finite element analysis (FEA), validly based on the ASME design rules and “Stress (Deformation) Analysis and Evaluation of Components and Devices - 2026” evaluation criteria.
In the static analysis results, it was shown that structural responses under the self-weight and maximum design internal pressure are both within the acceptable range. The self-weight load causes small stress and deformation, while the internal pressure affects the internal pressure-bearing region without causing significant global deformation. Modal analysis shows the pump structure is significantly more prone to low-frequency vibration effects compared with the impeller. The system remains globally stable with response localization in the central connection region under seismic loading case, whereas under harmonic loading case the response stays low and no obvious resonance amplification is observed.
