Abstract
Postoji vrlo mnogo područja primjene ultrazvučne tehnologije kao i raznih metoda ispitivanja ultrazvukom. Ovim radom opisani su neki načini moguće primjene ultrazvučne tehnologije u području održavanja u industriji koji se još uvijek vrlo malo primjenjuju ili se ne primjenjuju uopće. To su: Ispitivanje unutarnje propusnosti zaporne armature, Kontrola stanja ležaja i pravilno podmazivanje, Ispitivanje odvajača kondenzata, Ispitivanje instalacija komprimiranog zraka i stlačivih plinova i Ultrazvučno mjerenje protoka tekućina. Primjenom ultrazvučne kontrole u području održavanja moguće je otkriti mjesto kvara (propuštanje) i time bitno utjecati na smanjenje troškova uslijed gubitaka u eksploataciji. Ultrazvučnim otkrivanjem propuštanja moguće je postići korist na raznim područjima; od smanjivanja gubitka energije kod propusnosti na izmjenjivačima topline, lociranja propuštanja komprimiranog zraka, do lociranja propusnih mjesta na građevinskoj stolariji, propuštanja tekućina na vozilima, ... Zadatkom je trebalo prikazati konkretan primjer praktične primjene ultrazvučne tehnologije na ispitivanju ležaja. Ispitivanje ležaja se provelo metodom usporedbe ležaja u dobrom stanju sa „spornim“ ležajima koje je trebalo ispitati. Ležaji su se prekomjerno zagrijavali. Provedenim mjerenjima došlo se do zaključka da je do prekomjernog zagrijavanja na ležajima kao i unutarnjih oštećenja došlo zbog ventilatora koji nije centriran na osovini.
Abstract (english)
There are many areas of application of ultrasonic technology as well as various ultrasound examination methods. This paper describes some ways of using ultrasonic technology in the field of maintenance in the industry, which are still very little applied or not applied at all. These are: Testing the internal permeability of the locking armature, Checking the bearing condition and correct lubrication, Condensate separator test, Testing of compressed air and compressible gases installations and Ultrasonic flow flow measurement. Using ultrasonic control in the maintenance area, it is possible to detect a failure location and thereby significantly affect the cost reduction due to loss of exploitation. Ultrasonic detection of leakage can be beneficial in various areas; from reducing energy loss to heat exchangers, locating compressed air leaks, locating permeability spots on construction joinery… The task was to present a concrete example of practical application of ultrasonic technology on bearing testing. The bearing test was carried out by a bearing comparison method in good condition with the "discarded" bearings to be tested. The bearings were overheated. The measurements made suggest that excessive heating on bearings as well as internal damage occurred due to a fan not centered on the shaft held by the bearings.
