Numerical Simulation of Thermal Processes Occurring at Testing Hydrostatic Pumps in Cavitation Mode
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 1
Abstract
This article refers to the use of infrared thermography in the predictive maintenance of hydraulic drive systems. Based on experimental research on the temperature evolution in a hydraulic system which operates in cavitation mode, a numerical simulation model was built. The numerical simulation results are compared with experimental measurements in the points of interest of the hydraulic diagram versus numerical simulation model. The results obtained show that infrared thermal imaging camera procedure can be used in the limit of ± 10% errors as a predictive maintenance method in hydraulic drive systems.
