20.500.12556/RUL-165435 Avtomatizacija ventila za reguliranje delovne točke motorja črpalke Automation of the valve for regulating the operating point of the pump motor V diplomski nalogi je predstavljena problematika avtomatizacije obstoječih industrijskih procesov ter rešitev za enega izmed njih. V podjetju Kolektor Mobility d. o. o. se je pri testiranju električnega motorja pojavil nepričakovan padec navora. Po prvih domnevah je bil verjetno posledica spreminjanja viskoznosti olja s temperaturo. V iskanju rešitve se je porodila ideja, da bi obstoječi sistem nadgradili in ročni sistem zamenjali z avtomatskim, kar bi omogočilo natančnejše in lažje nastavljanje sistema. V okviru diplomske naloge je bilo najprej treba izbrati ventil. Odločili smo se za serijski ventil proizvajalca Bosch. Nato smo sestavili testno mesto za ventil, da sem lahko na enem motorju preizkusil delovanje ventila. Za to je bilo potrebno napisati nov program v okolju LabVIEW, kjer sem meril pretok ter tlak olja v sistemu. Krmiljenje je bilo do sedaj izvedeno ročno, kar pomeni, da je bilo možno poljubno nastavljati napetost na ventilu. V že obstoječi program, ki je namenjen testiranju, je bilo treba integrirati novo zanko, ki bo skrbela za krmiljenje ventila. Ko je krmiljenje delovalo na enem motorju, smo program prilagodili za vseh 12 kosov. Testiranje se je nato nadaljevalo tudi v komori, saj test zahteva različne temperature okolja. Končna verzija programa ustreza potrebam podjetja. V nadaljevanju bo potrebno spremljati delovanje ter po potrebi tudi malenkost prilagoditi parametre krmiljenja. S testiranjem smo ugotovili, da je sistem stabilen in na dolgi rok ne bi smel povzročati problemov. The thesis addresses the challenges of automating existing industrial processes and presents a solution for a specific application. During the testing phase of an electric motor at Kolektor Mobility d. o. o., an unexpected torque drop was observed, presumably due to the variation in oil viscosity with temperature. This led to enhancing the current system by replacing the manual control with an electronic valve, allowing for more precise system adjustments—a concept well-suited for thesis exploration. The initial step involved selecting an appropriate valve, and a serial valve from Bosch was chosen. Subsequently, a dedicated testing station was set up to assess the valve’s performance on a single motor. This required the development of a new LabVIEW program to measure oil flow and pressure within the system. Control was initially manual, enabling arbitrary voltage adjustments on the valve. A new loop responsible for valve control was added to integrate this into the pre-existing testing program. Once successful operation was achieved on a single motor, the code was adapted for twelve motors. Further testing was conducted in an environmental chamber to simulate various ambient temperatures. The final version of the program sufficiently meets the company’s requirements, though ongoing monitoring and minor parameter adjustments during testing are anticipated. Preliminary testing indicates system stability, suggesting long-term operational reliability.
