چکیده

The purpose of this study was to model and optimize the offline refinement operations of sugarcane harvester hydraulic oil using rsm. for this purpose, the effects of independent variables of operating hours (250, 500 and 750 hours), twin dip filter mesh (7, 9 and 11 microns) and hydraulic oil refining times (0, 1 and 2) on variables of water contamination, uncleanness level (nas), silicon (si), viscosity (vis) and oil acid number (tan) were evaluated. the results indicated that all models were suitable for water contamination, uncleanness level (nas), silicon (si), viscosity (vis) and oil acid number (tan) for describing experimental data. in addition, the desirability function showed that the optimum conditions for the offline refinement operations of the hydraulic oil of the sugar cane harvester included 728.61 operating hours, the 7micron filter mesh, and the two refining times of the oil. under this condition, the amount of water contamination, the uncleanness level (particles 5 to 15 micrometers), vis, si, and tan were equal to 187.63 ppm, 234000, 5.91 ppm, 66.34 centistokes and 0.65 (mg koh g1), respectively.

Abstract
|
The purpose of this study was to model and optimize the offline refinement operations of sugarcane harvester hydraulic oil using RSM. For this purpose, the effects of independent variables of operating hours (250, 500 and 750 hours), Twin Dip Filter Mesh (7, 9 and 11 microns) and hydraulic oil refining times (0, 1 and 2) on variables of water contamination, uncleanness level (NAS), silicon (Si), viscosity (Vis) and oil acid number (TAN) were evaluated. The results indicated that all models were suitable for water contamination, uncleanness level (NAS), silicon (Si), viscosity (Vis) and oil acid number (TAN) for describing experimental data. In addition, the desirability function showed that the optimum conditions for the offline refinement operations of the hydraulic oil of the sugar cane harvester included 728.61 operating hours, the 7micron filter mesh, and the two refining times of the oil. Under this condition, the amount of water contamination, the uncleanness level (particles 5 to 15 micrometers), Vis, Si, and TAN were equal to 187.63 ppm, 234000, 5.91 ppm, 66.34 centistokes and 0.65 (mg KOH g1), respectively.
