INNOVATIVE SOLUTIONS OF ADSORPTION CLEANING RECIRCULATING AIR FOR ELECTRIC TESTS OF ELECTRIC PRODUCT TESTS

The purpose of the study of this work: to provide a scientific justification for the energy-saving device to maintain the normalized parameters of the recirculated air in special “clean” rooms, to derive formulas for calculating the adsorption material during the operation of the installation. The novelty of the constructive solution is protected and confirmed by patents of the Russian Federation for the invention. Methods. The volume of adsorbent determined by this method is placed in a tank with a recirculation loop, which includes: a cleaning unit nozzle, the inner surface of which is spring-loaded with a grid placed on the side of a moving air flow and a grid around the entire outlet section of the expanding nozzle. Spring-loaded mesh, placed on the side of a moving air flow, is made according to the profile of the velocity profile of the moving air flow, which is caused by the manifold speed impact on the adsorbent grains, horizontally arranged layers in order to level the absorbing capacity of silica gel KSM-5 throughout the drying device and use in the system recirculation of the air supplied by the fan leads to a probable entry of the vaporous mass of oil into the stream being cleaned, and the analysis of scientific and technical oh showed no literature data on the nature of such contaminants granular filter material, resulting in the need to study the penetration of the oil by volume adsorbent per cycle electrical testing of electronic devices in a heat chamber. Results. Based on the analysis of well-known foreign and domestic theoretical and experimental studies, there was no development related to vibration effects on the efficiency of adsorption drying of recirculated air for electrical thermal testing of electronic products. An adsorption unit has been developed with a horizontal arrangement of an adsorbing substance for treating air under conditions of vibration effects. Conclusion The installation developed by the authors passed laboratory and industrial tests at the Mayak plant of Kursk and was recommended for implementation as a resource-saving constructive solution protected by patents of the Russian Federation for invention. Keywords: special premises electrical testing of electronic products, recirculation circuit in the chamber for temperature testing - heat chamber, adsorption drying, transparent body of the drying device, oil contamination.
