Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and they have to be removed or destroyed (bacteria, viruses, organic, sweat, hair, makeup, etc.). Treatment of swimming pool water is much more complicated because of the need to carry out her many times, than drinking water treatment, which is carried out one-time. Based on these studies, given technological solution to improve the efficiency of purification of circulating water in swimming pools, ensuring high environmental and economic performance of water treatment.

Efficient operation of separators bulk materials is possible when the relative velocity layer on the separating surface which knowledge is necessary to determine the optimal parameters and operating modes. Developed methods of measuring and determining the relative speed of the layer of granular material driving inside the rotating cylinder using a tachometer TCh-10P, which increased the size of the tip (roller), diameter with 31.4 mm to 62.8 mm, width 4 mm to 30 mm, and changed the material of the cushion rubber foam. This allowed tachometer TCh-10P to measure the speed of the layer, and to improve the measurement accuracy by reducing the moment of rolling friction and sliding the cushion layer. The relative error of the measurements during the experiments did not exceed 5% and is confirmed by the results of experimental studies of elastic separator. The technique may also find application in the determination of the velocities of the layer in inclined conveyors.

An analysis of snowplows in urban environments. Determined that the efficiency of snow removal from roads, sidewalks areas affected humps (bumps), borders, etc. In line with this analysis of structures working bodies (dumps), used in Russia and abroad, as well as analysis of patents. In accordance with the foregoing, all decisions on the management of blade can be divided: extra lever systems; modernization of hydraulic drive; use microprocessors; the combination of these approaches. Obviously, the use of processor technology is justified for high-tech machines, as a consequence has disadvantages in price, qualification of operators and maintenance personnel. For the modernization of existing equipment, at the moment, it is advisable to use the combined system using the lever and hydraulic drive systems. It is necessary to take into account the energy-saving technologies.

Trend of modern development of machine tools lathe group is the use of multiple tool holders, multi-position turrets. This makes it necessary to determine the radial stiffness in the area of treatment in all possible directions of load. In this paper, we propose a method and a method of control stiffness spindles lathes using load device, which allows to determine the static radial stiffness of the spindle assembly when the direction of the vector load. The load device is a cylindrical mandrel with a conical shank. The mandrel is set in a tapered hole of tailstock quill. The angular position of the load lock device corresponds to the direction of the force. The principle of operation of the device is to provide a radial load on the spindle caused by the elastic deformation of the sliding mandrel load device stops the inner conical surface of the spindle. Mandrel previously spanned. This allows to estimate the radial load created by bending mandrel controlled indicator secured thereon. The dimensions of the mandrel are determined finite element modeling depending on the inner cone of the front end of the spindle and the required radial loads. For the experiment was selected eight positions mandrel: the direction of the force was varied by rotating the load device in the bushing at an angle of 45 degrees. According to the results of the experiment was built hodograph elastic displacement of the spindle. Analysis of the results showed that there is a significant change in the stiffness of the spindle bearings depending on the direction of the load, that is experimentally confirmed anisotropy stiffness bearing spindle assembly.

In this article we consider the use of quasi-homogeneous approximation to describe the properties of disperse systems. We used a statistical method of polymer based on the consideration of all possible structures averaged macromolecules of the same weight. The equations to assess many additive parameters of macromolecules containing their systems. Statistical polymer method allows modeling branched, cross-linked macromolecules and containing their system in a state of equilibrium or non-equilibrium state. Fractal consideration of random polymer allows you to s imulate different types of random fractals and other objects studied by the methods of fractal theory. A method of statistical polymer is not only applicable to the polymers but also to composites gels associates in other polar liquids and aggregate systems. In this paper we described the state of colloidal solutions of silica from the viewpoint of statistical physics. This approach is based on the idea consists in the fact that a colloidal solution of silicon dioxide - silica sol consists of a very large number of interacting particles in a continuous motion. It is dedicated to the study of an idealized system of colliding, but not interacting particles sol. Analyzed the behavior of silica sol, in terms of Maxwell-Boltzmann distribution was calculated and the mean free path of the colloidal particles. Based on these data, it was calculated the number of particles that can overcome the potential barrier in a collision. For modeling the kinetics of the sol-gel transition, we have discussed various approaches.
