METHODOLOGY FOR CALCULATING THE ENERGY SUPPLY SYSTEM FOR REPAIR PRODUCTION SITES OF DOUGH DIVIDERS OF A VACUUM PISTON TYPE

Abstract

The efficiency of vacuum-piston type dough dividing machines is determined by the suction mechanism of the dividing device, when the parts of which are worn out, vacuum loss occurs due to which the accuracy of the dough weight is violated. The most promising method of restoring worn surfaces of parts of the suction mechanism is electric spark treatment. (Research purpose) The research purpose is developing a repair site for dough-dividing machines with the restoration of parts by the method of electric spark processing and proposing a methodology for calculating the energy supply system. (Materials and methods) Recommended the route of the technological process for the repair of dough dividing machines, which consists of the following operations: washing, defect, locksmith, mechanical, surfacing and control. The analysis of the process under consideration at the site showed that the health of the worker is affected by a complex of harmful production factors, such as noise, vibrations, dustiness, light exposure, release of chemicals into the air of the working area. Performed in the process of experimental research with the help of modern high-precision instruments measuring the level of indicators of these factors at the repair site of dough dividing machines. (Results and discussion) Measurements in the conditions of the implementation of the technological process allowed us to draw the following conclusions: the noise and vibration level is below the maximum permissible; air pollution is twice as high as the maximum permissible concentration. It was recommended, based on the data obtained, to provide workers with overalls and personal protective equipment. Using the example of supply and exhaust ventilation, we calculated the choice of technical parameters of the electric motor and ventilation ducts. It was noted that the introduction of the proposed energy supply system significantly reduces the level of harmful impurities in the air to optimal and acceptable values and eliminates serious diseases and poisoning of the human body. (Conclusions). The developed method of calculating the energy supply of production sites for the repair of dough-dividing machines allows to identify and eliminate harmful factors of the projected technological process. This technique can be used to determine dangerous and harmful factors in the design of production sites for the repair of other facilities.
