Kryshtopa S. Development of Scientific Bases of Increasing of Wear and Friction Properties of Brakes of Oil and Gas Equipment and Technological Transport

Scientific-applied problem of increasing of wear and friction properties and possibility of energy loading of brake devices of oil and gas equipment and technological transport are solved in the dissertation work. Triboelectric and electric dynamics, thermal, mechanical and chemical gradients, which develop in the superficial layers of friction units are explored. Physical fields of superficial layers of metal polymer friction pairs of coming distributing from in them of by volume charges and charging of their layers are appraised. Set influencing of the electric fields on wear and friction property of energy loading of brake devices metal polymer friction pairs. Communication of power levels of surfaces of friction during triboelectric co-operation and processes of thermo stimulation by polarization and depolarization by electric currents of surfaces of contacts on energy loading of metal polymer friction pairs is improved. Influence of change of types of contacts on direction of electric currents in superficial layers friction is produced. Nature of development of temperature gradients during circulation of electric currents in the superficial layers of friction elements is exposed. Method of internal determination and external operating pa-rameters of brake devices of oil and gas equipment and technological transport is developed. Constructions of the improved and new friction units of different types of brake devices of oil and gas equipment and technological transport with promoted possible energy loading and the improved wear and friction properties are offered.
