Abstract: Preventing asphalt-resinous and paraffin deposits (ARPD) in Irelyakh gas and oil field is one of the main problems. Gas condensate, which was used as a solvent in the field, could not completely clear paraffin deposits. This article shows the possibility of using gasoline Nefras solvent C2-80 / 120 as a solvent of asphalt-resinous and paraffin deposits in Irelyakh oil and gas field. Experimental studies of the solvent power of Nefras in the conditions of Irelyakh field were carried out and its effectiveness at different temperatures was determined. Kinetic studies of ARPD dissolving model reactions in the solvent at different temperatures showed that the use of the solvent to remove deposits on the oil fields would be effective

Abstract: Kinetic energy converts mainly into thermal and mechanic energy in the process of stopping-down. Experimental studies to assess the distribution of energy, released in the process of stopping-down, between thermal and mechanic components of energy balance are described; factors determining the value of mechanical component are identified; a design model to determine rational parameters of the break assembly is developed

Abstract: Braking devices, along with active wear effects are subjected to intensive heating. The intense heating of the surface layer reduces the strength properties of the metal, changes the coefficient of friction, intensifies the process of wear. Strengthening the heatsink of contact surfaces during sliding will significantly reduce their heating in the process of friction and thus reduce the wear and tear.
