20.500.12556/RUL-178164 Delovanje in nadgradnja turbinskega peskalnega stroja Operation and Upgrade of the Turbine Shot-Blasting Machine Diplomsko delo opisuje peskalni stroj kot napravo za mehansko obdelavo površine aluminijskega vlitega izdelka, ki je nastal v livarni. S peskanjem naredimo izdelek bolj obstojen na visoke temperature, ki nastanejo v motorju z notranjim zgorevanjem, in mu tako podaljšamo življenjsko dobo. V jedru diplomskega dela so na kratko predstavljeni različni postopki peskanja in različni tipi peskalnih strojev. Sledi opis zasnove stroja ter njegovih glavnih sestavnih delov, ki imajo pomembno vlogo pri njegovem delovanju. Podrobno je opisana regulacija delovanja turbin, kjer sta vrtilna hitrost in navor motorja povezana s tokovno regulacijo in spremembo hitrosti vrtenja. Tako enakomerno porazdelimo doziranje peščenega granulata po površini aluminijastega vlitega izdelka. Diplomsko delo obravnava tudi povezave med električnimi veličinami (tok, moč, vrtilna hitrost) in mehanskimi parametri, ki imajo pomembno vlogo pri peskanju. Po tehničnem opisu se diplomsko delo na koncu posveti tudi varnostnim parametrom. To so varnostni vidiki med samo uporabo stroja, filtrirne enote, preprečevanje preobremenitve motorjev in vzdrževalna dela. The diploma thesis describes the sand blasting machine as a device for mechanical surface treatment of aluminium cast products manufactured in the foundry. Sand blasting increases the product’s resistance to the high temperatures generated in an internal combustion engine, thereby extending its service life. The core of the thesis explains different types of sand blasting and briefly describes various kinds of blasting machines. This is followed by a description of the machine design, including its main components, which play important roles in operation. Particular emphasis is placed on the control of turbines, where the speed and torque of the motors are linked to current control and changes in speed of rotation. In this way, the dosing of the blasting media is evenly distributed across the surface of the aluminium cast product. The thesis also examines the relationships between electrical quantities (current, power, speed of rotation) and mechanical parameters, which play important roles in the blasting process. Finally, in addition to the technical description, the safety aspects of machine use are highlighted. These include operational safety, filtration units, prevention of motor overloads, and considerations for maintenance work.
