Abstract
Electroplating is an electrochemical process when a metal layer is deposited on the surfaces of a product. As an electrolyte, a solution of the salts of the deposited metal is used, the vaporization and micro-spray of which have an extremely negative and dangerous effect on humans and the environment. In this work, we present an environmental protection system for implementing the process of chrome plating of the internal surfaces of a hydraulic drive with hydrostatic guideways is presented. The schematic diagram of the environmental protection system includes the first stage of air purification (drip collector), the second stage of air purification (granular filter), as well as a system of granular filter cleaning and a radial fan. To clean the exhaust air from harmful substances, such as aerosols of chromium oxides and sulfuric acid, as well as water vapor, a comprehensive gas purification system for emissions of pollutants is proposed, consisting of step-by-step cleaning in various devices, including a drip collector with two droplet-breaking elements and a granular filter. The presented design of the environmental protection system equipment of the installation for chrome-plating the internal surfaces of a hydraulic drive with hydrostatic guideways will make it possible to effectively neutralize the air environment by cleaning the air from chrome anhydride vapor and other pollutants.

Within the framework of the project ‘Creation of a high-tech production of hydraulic drives with a wide range of hydrostatic guideways with low resistance to movement of moving parts and an increased resource for bench test equipment’, with the financial support of the Russian Ministry of Education and Science, a schematic diagram of an environmental protection system for conducting the process of chrome coating on the internal surfaces of hydraulic drives has been developed with hydrostatic guideways
To clean the exhaust air from harmful substances, such as aerosols of chromium oxides and sulfuric acid, as well as water vapor, a comprehensive gas purification system for emissions of pollutants is proposed, which consists of step-by-step cleaning in various devices, including a drip collector with two drop-off elements and a granular filter
