20.500.12556/RUL-116044 Izgradnja in postavitev sistema za avtomatski nadzor ter vzdrževanje emulzije Building and setting up a system for automatic control and maintenance of emulsion Diplomsko delo sega v področje hladilno mazalnih sredstev, ki se uporabljajo pri procesih odrezavanja. V industriji se pogostokrat premalo poudarka daje vzdrževanju hladilno mazalnih sredstev in preverjanju njihove kakovosti. Posledično tudi zaradi tega pride do motenj med delovnim procesom. V diplomskem delu so opisana in predstavljena najpogostejša hladilno mazalna sredstva ter njihovo vzdrževanje. Da bi si olajšali pregled nad kakovostjo in vzdrževanjem le-teh, smo razvili in postavili sistem za avtomatski nadzor ter vzdrževanje emulzije. Sistem deluje po principu krožnega procesa, saj meri emulzijo neposredno iz rezervoarja delovnega stroja ter jo tja tudi vrača. Na podlagi vrednosti, ki nam jih podajo senzorji in jih lahko preberemo na zaslonu, se sistem sam odzove in doda potrebno manjkajočo tekočino. V laboratoriju smo sistem testirali in ugotovili, da s svojo priročnostjo, mobilnostjo in zanesljivim delovanjem zelo pripomore k vzdrževanju hladilno mazalnih sredstev ter na ta način izboljša delovne pogoje med postopkom obdelave. The bachelor's thesis deals with metalworking fluids used in the turning processes. In industry there is often not enough emphasis placed on the maintenance of metalworking fluids and quality checks on them. Consequently, disruptions in work process may occur. The most common metalworking fluids and maintenance of those fluids are presented and described in the bachelor’s thesis. To facilitate the overview of quality and maintenance, we developed and set up a system for automatic control and maintenance of emulsion. The system operates on the principle of cyclic process: it measures the emulsion directly from the tank of the working machine and returns it back to the tank. Based on the values obtained by the sensors that can be read on the screen, the system automatically responds and adds the necessary fluid. The system was tested in a laboratory and the results showed that the convenience, mobility and the reliability of the system contribute greatly to the maintenance of metalworking fluids. As a result, this improves the working conditions during the machining process. hladilno-mazalna sredstva odrezavanje emulzije senzorji črpalke refraktometer metalworking fluid turning emulsions sensors pumps refractometer true false false [L.
