System upgrade of technical diagnostics at Cinkarna Celje, d. d.

Proizvodno podjetje je v veliki meri odvisno od neprekinjenega in pravilnega delovanja strojev in naprav v proizvodnji, zato mora vzdrževanju, kot delovnemu procesu, nameniti posebno pozornost in ga ne sme obravnavati samo s stroškovnega vidika. V podjetju Cinkarna Celje, d.d., se tega zavedajo vsi, vodstvo in zaposleni, saj je vzdrževanje kot funkcija enakopravno vključeno v organizacijsko shemo in v letni finančni načrt podjetja, deluje pa kot samostojna poslovna enota. V podjetju sledimo tehnološkim novostim na področju strojev in naprav za proizvodnjo. Temu prilagajamo tudi načine in sisteme vzdrževanja, tako da nadgrajujemo stare diagnostične metode in, glede na novosti, uvajamo nove, ki se pojavijo. V diplomskem delu je predstavljenih vseh sedem glavnih metod, na podlagi katerih v podjetju izvajamo preventivno vzdrževanje: termografija, lasersko uravnavanje, uravnoteženje rotorjev na mestu, odkrivanje puščanj na sistemu komprimiranega zraka, obvladovanje kondenčnih lončkov, meritve vibracij in kontrola maziv. Opisana je uvedba tehnologije za diagnostiko vibracijskega stanja. Predstavljeni so vsi dejavniki, ki vplivajo na izbiro nakupa in uvedbo nove tehnologije s področja preventivnega vzdrževanja, in postopki, ki jih je potrebno izvesti za uspešno izvedbo projekta ter dosego cilja izboljšanja diagnostike napak na napravah.A manufacturing company depends mostly on continuous and proper functioning of machinery and equipment. It is necessary to pay special attention to the maintenance which should not be viewed as a mere cost. In our company the board of executives and the employees are aware of that. That is why we have the maintenance fully incorporated in the organizational scheme and in the annual financial plan where it functions as an independent department. Our company closely follows technical advancement in the field of machinery and equipment, so as to adjust the system of maintenance by improving the existent diagnostic methods as well as adopting new ones. In this thesis, all seven basic methods are presented on the basis on which preventive maintenance functions: thermography, laser alignment, rotor balancing, leaks detecting in the system of compressed air, the condenser pots handling, vibration measuring, and the control of lubricant. The introduction of technology for diagnosis of vibrations is presented as a project. Furthermore, we also present all the factors relevant in employing new technologies as well as the procedures necessary to implement the project and to reach the final goal: improvement of the diagnosis in detecting malfunctioning of machinery and equipment
