Abstract [en]

This thesis analyzes BTPX 305, a biotech separator developed by Alfa Laval. It focuses on a problem found in the vertical drive where the machine's vibration absorber and damper take place. Today the machine is experiencing vibration above the normal levels, and the product that the machine usually separates is very sensitive to vibration. Therefore, the damping mechanism in the machine needs to be serviced often because of wear in the damping mechanism. In the report, a variety of methods are used, TIPS (the Theory of Inventive Problem Solving) for example are used to model and describe the problem in more detail, and internal/external research is done to possibly find inspiration from other machines that have solutions to similar problems. Solution ideas were generated in brainstorming sessions that were mostly inspired by the information gathered from both the internal and external sources. The concepts were then adapted to then become a solution proposal to the problem. With the help of a priority matrix, it was decided which of the concepts should be considered reasonable as a solution proposal. A couple of experiments were conducted on the concepts that were further taken from the priority matrix to ensure that the theory works in practice.

Abstract [sv]

Projektet analyserar BTPX 305, en biotechseparator utvecklad av Alfa Laval. Arbetet fokuserar på ett problem som finns i den vertikala enheten där maskinens vibrationsdämpare äger rum. Idag upplever maskinen en vibration över normala nivåer. Produkterna som maskinen brukar separera är mycket känslig för vibrationer och därför måste maskinen ofta kontrolleras på grund av slitage i dämpningsmekanismen. I rapporten används olika metoder, till exempel används TIPS (the Theory of Inventive Problem Solving) för att modellera och beskriva problemet mer detaljerat och en intern/extern forskning görs för att eventuellt hitta inspiration från andra maskiner som har lösningar för liknande problem. Lösningsidéer genererades i brainstorming sessioner som inspirerades av den informationen som samlats in från både interna och externa källor. Koncepterna anpassades sedan för att bli möjliga lösningsförslag till problemet. Med hjälp av en prioriteringsmatris bestämdes vilka av lösningsförslagen som skulle anses vara rimliga att arbeta vidare med. Ett par experiment gjordes på de koncepten som togs vidare från prioritetsmatrisen för att säkerställa att teorin fungerar i praktiken.
