Description
The article is devoted to the development of a compressor type ozonator. It describes the design of a high-productivity compressor ozone generator, which can be used for industrial decontamination of mixed feeds, water, milk, and in the system of presowing treatment of seeds. This construction allows generating ozone with high concentration to 5 g/m3 at high feed air or oxygen from the compressor station (up to 2000 l/min). The article describes the design of the basic elements of tubular ozone generator, examines the factors influencing the productivity of the ozonator. The proposed mathematical model allows calculating the productivity of the ozonator when considering multiple influencing factors. These factors take into account: the parameters of supply voltage, such as the magnitude and frequency of the supply voltage; the configuration and geometrical parameters of electrodes such as, the area of the electrodes, the configuration of the surface of the electrodes and distance between electrodes; parameters dielectric barrier; and the transported gas parameters such as volume, temperature, pressure and composition. Special attention is paid to the design of the electrodes made of woven wire mesh with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted, that such electrodes allow obtaining the maximum productivity of an ozonator, and they do not lead to overheating of the dielectric barrier, and do not output down the generator. In the same way, the article presents the results of the mathematical modeling of ozone generator productivity while changing various factors

ADJUSTABLE BALLAST RESISTANCE FOR MOTORS WITH SLIP-RING MOTORS IN THE BREAK-STANDS
Description
The article presents an overview of the run-in and testing of internal combustion engines, the analysis of break-brake- stands. We gave recommendations on expediency of the application of asynchronous motors with phase rotor winding on modern stands; we also considered its advantages over asynchronous motor with a short-circuited winding. As an alternative to the modern techniques, we have proposed a scheme of adjustable ballast circuit rotor using PWM modulation current. The process of adjustable ballast resistance and implementation of major break-regimes using the proposed device was also considered in this study
