Dodatkowe opory ruchu przenośnika zgrzebłowego rurowego

Jedną z istotnych wad przenośników zgrzebłowych rurowych są znaczne opory ruchu i powodowane nimi zużycie ścierne rynien i zgrzebeł. Dlatego do racjonalnego projektowania tych przenośników istotna jest znajomość nie tylko oporów podstawowych, ale i dodatkowych, które były przedmiotem analizy w tej pracy.

Scarper pipe conveyors can assure dust, water and even gas tightness, and their routes can be easily configured in horizontal and vertical planes. Because of their advantages, like simple construction and maintenance, silent operation, small crosswise section systems, the ability to transport materials in full isolation from the environment (also hot ones up to a temperature 700'C), those conveyors have got wider application in aluminium-works, cement plants, coke plants, filters evacuation systems, and in the ceramic, chemical and primary industries. One of the real disadvantages of scraper pipe conveyors is the great resistance of movement and wear of pipes and scrapers. A very important problem of designing scraper pipe conveyors is the knowledge of their resistance to movement and drive power according to the parameters of construction and motion and also the type of handled materials. For the rational designing of those conveyors, it is essential to know the basic sources of the resistance of movement and the additional ones, which were subject of this paper. The results of these calculations allowed us to obtain the dependencies on additional resistance to the movement of the scraper pipe conveyor connected with the displacement of material on bends in the pipes, and also the resistance of conveyor loading. Dependencies on additional resistance to movement can be used during detailed calculations of scraper pipe conveyors, but also can be useful for cognitive and practical reasons.
