AUTOMATIC CONTROL OF THE TECHNOLOGICAL REGIME IN DEVICES WITH ENAMEL COATING ON THE INNER SURFACE OF PIPES

Abstract

According to experimental research and practical experience, the main problems with enamel coated pipes are the roughness inside the pipe, small air bubbles, and cracks that come in different sizes, all of which make the pipes not last as long. Consideration is given to the issue of enamel coating defects, which compromise the enamel's structural integrity. The reasons for these defects are associated with the wrong choice of technological mode when applying enamel coatings to the inner surface of pipes. The choice of the technological mode when applying the coating depends on the geometric dimensions and technological parameters of the pipes. It is known that incorrect implementation of the technique of applying enamel coatings to pipes leads to the formation of micro cracks. Considering all this, the main task of the research carried out is the automatic adjustment of the parameters of the technical mode of the equipment and the tuning of the control system to prevent the formation of micro cracks during coating and the improvement of the automatic control. of the process.
