20.500.12556/DKUM-84283 Vpeljava preventivnih meritev vibracij z napravo SKF Quickcollect in sistem za stalni nadzor na kritičnih točkah papirnega stroja magistrsko delo Introduction of preventive vibration measurements with the SKF Quickcollect device and the system for continuous monitoring at critical points of paper machine Preventivno vzdrževanje strojev in izvajanje meritev vibracij sta v proizvodnem procesu zelo pomembna dejavnika, saj redno vzdrževanje in pravočasno odkritje napak lahko pomembno vpliva na uspešnost poslovanja podjetja ter znižanje stroškov vzdrževanja. S pravočasnimi ukrepi tako povečujemo razpoložljivost stroja, zmogljivost in kakovost. V magistrskem delu sem v ta namen predstavil osnove merjenja in vrednotenja vibracij v industriji, s katerim lahko ugotavljamo številne nepravilnosti, ki se pojavijo tekom obratovanja (ali pa tudi mirovanja) stroja ali naprave. Na papirnem stroju smo v praksi uvedli tedensko izvajanje meritev vibracij na kritičnih napravah novega papirnega stroja, na podlagi katerih bo lahko podjetje v bodoče spremljalo in tudi analiziralo izmerjene vrednosti ter tako tudi bolje in ustrezno planiralo preventivno aktivnost. Z namenom hitrejšega izvajanja smo izdelali QR kode, v katerih se nahajajo podatki o vgrajenih ležajih, alarmnih vrednostih ter hitrosti obratovanja naprave. Izvedli smo primerjavo stroškov med uvedbo stalnega nadzora vibracij ter izvajanja meritev s strani zunanjega izvajalca ter podjetju predstavili glavne prednosti in slabosti obeh načinov. Z rednim izvajanjem meritev lahko pomembno zmanjšamo nenačrtovane izpade proizvodnje, povečamo varnost in učinkovitost delovanja stroja. Preventive maintenance of machines and performance of vibration measurements are very important factors in the production process, as regular maintenance and timely detection of errors can have a significant impact on the success of the company's operations and the reduction of maintenance costs. By taking timely measures, we increase machine availability, capacity and quality. For this purpose I presented the basics of measuring and evaluating vibrations in industry, which can be used to identify many irregularities that occur during the operation (or standstill) of a machine or device. At the paper machine, we have implemented weekly vibration measurements on the critical devices of the new paper machine, based on which the company will be able to monitor and analyze the measured values in the future and appropriately plan preventive activities. In order to perform measurements faster we created QR codes that contain datas about the installed bearings, alarm values and device operating speed. We performed a cost comparison between the introduction of permanent vibration control and the performance of measurements by an external contractor, and presented the company with the main advantages and disadvantages of both methods. By regularly performing measurements, we can significantly reduce unplanned production downtime, increase safety and the efficiency of machine operation. preventivno vzdrževanje izvajanje meritev vibracij papirni stroj zastoji preventive maintenance performing vibration measurements paper machine shutdowns true true false [Ž.
