20.500.12556/DKUM-75950 Sprememba sestavnih delov izpušnega ventila vodne črpalke kavnega avtomata diplomsko delo Change of exhaust valve components in coffee machines water pump Cilj diplomskega dela je spoznati tehnološki in ekonomski vidik proizvodnje izpušnih ventilov in potem vgrajevanje le-teh na vodne črpalke, kar imenujemo podsklop. Glavni problem je nedoseganje norm, in sicer zaradi slabih izpušnih ventilov, kar pripelje do nepravilnega delovanja celotnega podsklopa. Posledice nepravilnega delovanja so zavrnitev in vračilo podsklopov nazaj v dobaviteljsko podjetje. Glavni problemi so torej nedelujoči podsklopi, nedoseganje norme delavcev in poraba dodatnega časa za popravilo. Posebno pozornost smo posvetili preoblikovanju izpušnega ventila, kar reši naše probleme. V diplomskem delu pa so predstavljeni tudi ekonomski izračuni za izdelavo starega in novega izpušnega ventila ter tudi ekonomski izračuni za izdelavo podsklopa črpalka in izpušni ventil. Predstavljena so tudi delovna mesta v proizvodnji ter polizdelki, ki jih naročniško podjetje kupi in katerega proizvede sam. Na podlagi končnih rezultatov je bilo ugotovljeno, da se sestavni deli izpušnega ventila lahko spremenijo in s tem odpravimo težavo nepravilnega odpiranja, kar se je kasneje tudi zgodilo. Zaradi zaupnih podatkov podjetja so vsi stroški za izdelavo in zmanjšanje slabih serij izpušnih ventilov predstavljeni približno. The main aim of the diploma is to get to know the technological and economical aspect of the production of exhaust valves and then installing them on water pumps, called the subassembly. The main problem is not reaching the standards due to poor exhaust valves, which results in the malfunctioning of the entire subassembly. The malfunction results in the refusal and return of the subassemblies back to suppliers’ company. The main problems are the inactive subassemblies, the failure to reach the standard of workers and the use of extra time for repair. Particular attention was paid to redesigning the exhaust valve, which solves our problems. The diploma also presents economic calculations for the manufacture of old and new exhaust valves, as well as economic calculations for the manufacture of pump sub-assemblies and exhaust valves. There are also manufacturing jobs and semi-finished products that subscription company buys and manufactures. Based on the final results, it was found that the exhaust valve components could be modified to eliminate the leakage problem, which later happened. All costs of producing and reducing bad batches of exhaust valves are approximate, due to confidential company information.
