20.500.12556/RUL-147626 Degradation of hydraulic system due to wear particles or medium test dust Contamination in hydraulic systems is the cause of 70% of failures. This study highlights the performance degradation caused by solid particle contamination of hydraulic components: hydraulic gear pump, 4/3 valve, and orbital motor. Experimental durability tests of components with wear particles and test dust are used to investigate the effects of accelerated wear caused by these two types of contaminants. Results show that oil contaminated with wear particles reduces the volumetric efficiency of the gear pump by 18% and the hydraulic valve by only 0.8%, while oil contaminated with test dust reduces the efficiency of the pump by 76% and the hydraulic valve by 0.9%. This research provides insights for accelerating hydraulic component testing to improve system reliability and longevity. hydraulic system oil cleanliness gear pumps directional 4/3 valves orbital motors wear internal leakage volumetric efficiency hidravlični sistem čistost olja zobniške črpalke smerni ventili 4/3 orbitalni motorji obraba notranje puščanje volumski izkoristek true false true Angleški jezik Slovenski jezik Članek v reviji 2023-07-10 09:22:43 2023-07-10 09:22:45 2025-02-20 13:48:20 0000-00-00 00:00:00 2023 0 0 20 str. iss. 13, art. 7777 Vol. 13 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.22 2076-3417 10.3390/app13137777 158275843 Novak_..._Degradation_of_Hydraulic_System_due_to_Wear_Particles_or.pdf Novak_..._Degradation_of_Hydraulic_System_due_to_Wear_Particles_or.pdf 1 9C8EFD4EF131E1CC24A4E3BB328B780A 40520b916c60e5976e8739b0ef11f3df176c96d8cef581a411471f34ee04f6cf a248a04f-1ef2-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=171281 https://www.mdpi.com/2076-3417/13/13/7777 1 22b8a0ce-1ef2-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=171280 Fakulteta za strojništvo 0 0 0
