Sažetak
Hidraulični sistemi mobilnih mašina su često kontaminirani čvrstim česticama. Čvrste čestice povećavaju intenzitet abrazivnog habanja hidrauličnih komponenata, i čine jednim od glavnih uzročnika otkaza sistema. U radu je dat prikaz reprezentativnog primera uticaja čvrstih čestica na povećano habanje delova hidrauličnog čekića bagera u eksploatacionim uslovima bagera u cementnoj industriji.
Abstract
Hydraulic systems of mobile machines are often contaminated by solid particles. Solid particles increase the abrasive wear intensity of hydraulic components and present one of the main causes of system failure. The paper presents a representative example of the solid particle influence on the wear intensity of hydraulic hammer parts, in the cement industry environment.
