One of the most important technological characteristics of the rubbing surfaces of the shut-off part of the pipe fittings (PF) of the transport pipeline systems (TPS) is their waviness, which is characterized by the deviation of the step of the wave to the height of the micro-roughness. The nature of the waviness is associated with oscillations of the working bodies of the executive devices of the technological equipment in the production process of manufacturing or repairing precision pairs of PF. The waviness of the rubbing surfaces of the PF shut-off part, as well as the high accuracy of their processing, is achieved by increasing the kinematic stiffness of the process equipment, as well as improving the methods and means for the precise processing of the PF precision pairs.

AbstractThe quality of refractory materials plays an important role especially in high temperature processes. In case of violation of qualitative properties of refractory materials, the safety of the use of the technological equipment in which these materials are used is compromised. The requirements on the quality of refractories and their properties are now high, as their operating life should be as long as possible. The aim of the article is to point out the quality of refractory material in contact with corrosive media, to analyze the technological factors that affect the quality and safety of technological equipment. An analysis of the refractory material, as well as the analysis of the melt was performed. Subsequently, an experiment was realized, which was evaluated by macroscopic analysis and chemical analysis. After the experiments, we found that the melt had penetrated the masonry and consequently created corrosion layers in the masonry. These layers have affected the life of the material and reduced the safety of the technological equipment in which they were used.

The peculiarity of the technological equipment of light industry is the significant dynamic loads that occur during unstable operating modes and is one of the main reasons for reducing the reliability and durability of its operation. The problem of increasing the reliability and durability of their work by reducing the dynamic loads is relevant, because the known means of reducing the dynamic loads in the drive of machines can not always be used in light industry machines. Therefore, when designing light industry equipment, first of all, attention should be paid to reducing the dynamic loads in the drive and preventing accidents. The paper considers the feasibility of using a device with a torsion spring to reduce the dynamic loads in the drive of process equipment, check its performance and develop a method for selecting rational parameters. In the course of work modern methods of researches of mechanical systems are used for the purpose of an estimation of expediency of use of the device with a torsion spring for reduction of starting dynamic loadings in the drive of machine. On the basis of the analysis of features of work of the technological equipment of light industry the expediency of use in the drive of cars of the gear safety coupling with a torsion spring is established. A new design of the device is proposed to reduce the dynamic loads that occur during machine start-up. Unlike the known devices, the proposed device is made in the form of a toothed safety clutch with a torsion spring, which simplifies its design and increases efficiency. The use of a cylindrical torsion spring as an elastic element, which connects the half-clutch to the flange on which the satellite gears are mounted, prevents overloading of the drive and the choice of rational rigidity of the device depending on the change of operation, which increases its durability and expands performance. The method of checking the efficiency of the device for reducing dynamic loads and selecting its rational parameters is presented. The scientific novelty is the development of scientific bases and engineering methods of designing devices to reduce dynamic loads in the drive of technological equipment. The practical significance lies in the development of a new design of the device to reduce the dynamic loads in the drive of machines and the engineering method of choosing its rational parameters.

A new approach to providing the necessary temperature of technological equipment of various industries, in particular, chemical, food, microbiological, heat and power, and therefore a stable thermal mode of processing the flows of substances and materials that are in the specified equipment is proposed. It has been proposed to make working bodies and elements of equipment in contact with the flows of the substances and materials being processed from magnetic material with a phase transition temperature of the second type (Curie point), which corresponds to the temperature of the technological process. The designs of tubular heat exchangers, dryers, packed and disc mass transfer columns, separators, equipment for the processing of thermoplastics (extrusion head, static mixers, worm extruder), as well as bulk feeder are considered.

Machinetools belong to the basic technological equipment in mechanical engineering ensuring the creation of other machines with high accuracy and productivity unattainable in coming decades on the basis of additive techniques. Machining accuracy on machinetools is an integral index of quality and despite the diversity of approaches to the identification of correla-tions, computations and estimates of machining accuracy, the value of a general error seems to be as a sum of partial errors. A significant part in the formation of a general error of machining cause machinetools them-selves. Besides, a significant role in assurance of guaranties for machinetools users (operators) the standards for their geometrical accuracy play. A significant problem having scientific and practical meaning is the absence of a single approach substantiated scientifically to the formation of a system of such standards both for machine-tools of new types, and for the revision of the system with actual standards on geometrical accuracy of machinetools. In the paper there are offered methodological fundamentals for the parameters standardization of machine-tools geometrical accuracy on the basis of revealed interrelations between accuracy of units and parts surfaces machined at the use of a variational method for the computation of machines accuracy. The practical use of the approach offered requires both the development of the variational method itself for the computation of machines accuracy in the field of obtaining corresponding estimates of accuracy of various surfaces machined, for example, deviations from parallelism of two faces and others, and thorough investigations of the structure of relationship equations themselves.
