Sarzhanov B. Development of ecologically safe augers restoration methods of manure utilization technological cycle machines

The dissertation is devoted to the solution of the actual scientific and technical problem in the field of branch mechanical engineering: development of innovative, short - term and ecologically safe technologies of surface strengthening and repair of augers of machines of technological cycle of utilization of manure, and also the centrifuges intended for domestic and industrial sewage treatment. Solving this problem will increase the reliability of machines by increasing the service life of their working bodies, while reducing energy consumption, which is very important for modern Ukraine. The system of the directed choice of the most effective technology of protection of screws of the cars involved in a technological cycle of removal and utilization of manure in livestock complexes with a large number of pigs and cattle and centrifuges on sewage treatment working with constant loading in severe conditions of hydroabrasive wear and tear, and a negative environment. The combined technology of restoration of landing surfaces of details including environmentally friendly safe methods of ESA and application of MPM, which provides by reinforcing the latter, increasing the hardness and strength of the applied coating. The ecologically safe technology of strengthening of details from sheet steel by the CESA method which application is followed by: considerable (by an order of magnitude) decrease in expenses of the electric power and time for heat treatment is developed; the absence of leashes and grooves, and hence the need for additional machining to eliminate them after heat treatment. It is proposed to replace environmentally harmful technology of welding segments with wear-resistant coatings on worn sections of auger blades with environmentally friendly, which consists in attaching mechanically. Developed and implemented in the production of technological recommendations for the manufacture and repair of augers of machines involved in the technological cycle of removal and disposal of manure and centrifuges for wastewater treatment, environmentally friendly methods.
