Abstract: The hydraulic resistance of dry direct flow valve sieve tray of new design was studied. The operation of the tray is described and a design equation of the resistance is obtained. The resistance of direct flow valve dry tray and that of trapezoid valve dry tray are studied for comparison the data on the dry direct flow valve sieve tray are contrasted to those of the trays of comparison

Abstract: Creating a number of information systems in the field of oil and gas processing and gas chemistry requires the development of a joint classifier of oil and gas processing and gas chemistry equipment. A review of present-day technologies is presented. The results of the analysis of applicability of current classifiers for creating a classifier of the oil and gas processing and gas chemistry equipment are given. The possibility of creating a model of the classifier in a university is shown

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.
