ADAPTIVE INFLUENCE OF PRESSURE CHANGE OF THE HYDRAULIC SYSTEM OF THE HYDRAULIC DRIVE

The efficiency of hydrogenated machines various technological purposes depends to a large extent on the temperature environment. Temperature is main factor in hydraulic drive, which changes physical properties working fluid: viscosity, moisture content, gases and mechanical impurities, determine its modulus elasticity. Efficiency significantly reduced both at low temperatures high temperatures. high-temperature mode drive reduces technical operational performance (construction road, mountain, agricultural other self-propelled machines). High one most important factors that intensively affect aging fluid. An increase lubricant above 70° C leads decrease lubricating capacity premature wear equipment, an leakage lubricant, thermal destruction with formation tarry deposits internal surfaces equipment. Intensive observed due friction surfaces, volumetric machines, linear dimensions heated elements, as result, accuracy operations deteriorates resource equipment reduced. All this parameters productivity reliability machines. Hydrogenated operated elevated require number measures heat transfer stabilize regime. This article examines issue determining given elasticity system using example experimental model TT4M-23L tracked crawler tractor relationship pressure temperature. equation calculated allows establishing between system.
