The main directions of technical progress in the field of creation and use of the hydraulic technique is associated with increased operating pressures, the creation of electrohydraulic control equipment for self-propelled machines, increasing capacity, improvement of characteristics of hydraulic transmissions, extension of temperature range of application of the hydraulic drive through the use of new varieties of mineral and synthetic working fluids and creating special hydroelements to use machines in conditions of cold and/or hot climate. In the article the methods of heating the working fluid of the hydraulic drive when operating in low temperatures. The purpose of this study is to develop a technical proposal to improve the durability of the hydraulic drive self-propelled machines. Method of increasing durability of the hydraulic drive, working in low temperatures is a preheating of the working fluid by throttling. As a result of the proposed design of the inductor heating with automatic control orifice remotely, depending on the temperature of the working fluid in the tank of hydraulic system and presents the method of calculation of the main parameters of the proposed reactor to facilitate its implementation. Thus, when implementing the proposed reactor operating organization will have the opportunity to carry out heating of the working fluid with minimal energy consumption and improve the durability of the hydraulic drive, which will lead to increased productivity, decrease downtime and increase profits.
