abstract = "Cooling towers use significant amounts of water, and the cooling system is often the most
efficient energy user in a building during the cooling season. Maximizing the energy efficiency of
the cooling system can be significantly improved by optimizing the cleanliness of the tower heat
transfer surfaces and the heat transfer surfaces of the heat exchanger cooling system. Cooling
towers belong to the group of contact heat exchangers, and they are an integral part of almost
every process plant, which failure can produce long-term downtime and significant material losses.
Bearing in mind this fact, it is necessary to check electric motor, the fan and its components in a
reliable way in order to ensure the required continuity of the process in the appropriate period of
time. Previous methods of checking fan parts in accordance with the manufacturer's manuals included only visual inspection of the fan blades and checking the tightening torque of the blades
for their holders. The mentioned methods have proven ineffective and insufficient from the point of
view of maintenance of process plants during working life, which has led to the fan's failure and the
blade holder's breakage at the point of connection with the blade. Hence, for the needs of
appropriate maintenance, the conventional non-destructive methods for the assessment of surface
and volumetric defects of blade holders have been applied. This methodology for checking the blade
holders has been presented in detail in the paper., Kule za hlađenje koriste značajne količine vode, a sistem za hlađenje je često najefikasniji korisnik energije u zgradi tokom sezone hlađenja. Maksimiziranje energetske efikasnosti sistema za hlađenje može se značajno poboljšati optimizacijom čistoće površina za prenos toplote kule za hlađenje i površina za prenos toplote sistema za hlađenje izmenjivača toplote..Kule za hlađenje
vode spadaju u grupu kontaktnih razmenjivača toplote, i sastavni su deo gotovo svakog procesnog
postrojenja, čiji otkazi mogu dovesti do dugotrajnih zastoja i značajnih gubitaka materijala.
Imajući u vidu ovu činjenicu, neophodno je na pouzdan način proveriti electromotor, ventilator i
njegove komponente kako bi se obezbedio potreban kontinuitet procesa u odgovarajućem
vremenskom periodu. Ranije metode provere delova ventilatora u skladu sa uputstvima proizvođača
uključivale su samo vizuelnu proveru lopatica ventilatora i proveru momenta zatezanja lopatica za
njihove držače. Pomenute metode su se pokazale neefikasnim i nedovoljnim sa stanovišta
održavanja procesnih postrojenja tokom radnog veka, što je dovelo do kvara ventilatora i loma
držača lopatica na mestu spoja sa lopaticom. Stoga su, za potrebe odgovarajućeg održavanja,
primenjene konvencionalne nedestruktivne metode za procenu površinskih i zapreminskih defekata
držača lopatica. Ova metodologija provere držača lopatica je detaljno prikazan u radu.",
