Abstract

Tema ovog završnog rada je dijagnostika stanja rotacijskih strojeva primjenom ultrazvuka. Rotacijski strojevi su uređaji koji koriste rotacijsko gibanje za obavljanje rada. Primjeri uključuju motore, generatore, pumpe, kompresore i turbine. Rad sadrži teorijski i praktični dio. Teorijski dio obuhvaća fiziku ultrazvuka, osnove ultrazvučne dijagnostike te primjene ultrazvuka u industriji. Ova teorijska osnova omogućuje razumijevanje praktičnog dijela u kojem se eksperimentalnim metodama detektira stanje ležaja. Eksperimentalne metode uključuju simulator kvarova ležaja i SDT340 ultrazvučni uređaj. Primjenom eksperimentalnih metoda ne samo da će se detektirati stanje ležaja, već će se i identificirati dijelovi na kojima se pojavljuje oštećenje. Ležajevi su ključni za održavanje pouzdanosti i dugovječnosti rotacijske opreme jer omogućuju glatko i stabilno funkcioniranje rotacijskih dijelova.

Abstract (english)

The topic of this thesis is the diagnosis of the condition of rotating machinery using ultrasound. Rotating machinery refers to devices that utilize rotational motion to perform work. Examples include motors, generators, pumps, compressors, and turbines. The thesis consists of both theoretical and practical parts. The theoretical part covers the physics of ultrasound, the basics of ultrasonic diagnostics, and the applications of ultrasound in industry. This theoretical foundation enables the understanding of the practical part, in which the condition of bearings is detected using experimental methods. The experimental methods include a bearing fault simulator and the SDT340 ultrasonic device. By applying experimental methods, not only will the condition of the bearings be detected, but also the specific parts where damage occurs will be identified. Bearings are crucial for maintaining the reliability and longevity of rotating equipment as they ensure the smooth and stable operation of rotating components.
