Abstract

Horizontalne balirke so namenjene baliranju večjih količin odpadnega materiala. Balirke poganja hidravlični sistem, ki mora zagotavljati visoko zmogljivost in potisno silo s čim nižjo pogonsko močjo za pogon dveh glavnih funkcij, to sta predstiskanje s pokrovom in stiskanje z glavnim stiskalnim valjem, ter vračanje obeh v izhodiščni položaj. Da bo zmogljivost balirke čim višja, morata biti ti dve funkciji opravljeni v čim krajšem času. V diplomskem delu so obravnavane različne rešitve hidravličnega dela pogonskih enot in različne rešitve hidravličnega krmilja balirke. Posamezne rešitve so časovno ovrednotene, navedene so prednosti in slabosti posamezne rešitve. Končna rešitev hidravličnega sistema, ki predvideva uporabo regulacijske črpalke, dodatne črpalke s konstantno iztisnino, ter krmilne enote z »varčno« in zaporedno vezavo, je sicer nekaj dražja, a je čas delovanja bistveno krajši od osnovne rešitve. S tem je tudi dosežen osnovni cilj diplomskega dela.

Secondary title:	HORIZONTAL BALERS – POSSIBLE HYDRAULICS SOLUTIONS
Secondary abstract:	Horizontal balers are designed for baling large quantities of waste material. Balers are driven by a hydraulic system, which should provide high performance and thrust with the lowest possible power output to drive the two main functions, i. e. the prepressing with a flap and pressing with the main cylinder, and return both to the starting position. These two main functions should be carried out in the shortest possible time. To have the capacity as high as possible, the two functions should be carried out as quick as possible. Different solutions of hydraulic drive units and different solutions of hydraulic control are shown. Individual solutions are time-evaluated, and the benefits and weaknesses of each solution are stated. The final solution of hydraulic system with variable displacement pump, additional pump with fixed displacement, control unit with "saving" and a series connection is a bit more expensive. However, the operating time is significantly shorter than the basic solution. Thus, the basic goal of the thesis is achieved.
