Abstract
Zgłoszenie dotyczy przyrządu do badania dysz zraszających, stosowanych w organach urabiających kombajnów górniczych. Przyrząd (1) ma korpus (2) w postaci tulei wyposażonej w środkowej części w podłużne, wykonane od góry wycięcie (3) w płaszczu. Jeden koniec (2') wyposażony jest w tarczowy uchwyt (4), w którym mocowana jest badana dysza zraszająca, a z drugiego końca (2") zamknięta jest głowicą pomiarową (6), we wnętrzu której osadzone są wkłady kontrolne (7a, 7b, 7c). Wkłady kontrolne (7a, 7b, 7c) swoimi zwróconymi ku dyszy zraszającej powierzchniami stożkowymi wyznaczają krawędzie (10), między którymi tworzą się kanały (11) dla rozpylonego pod różnymi kątami strumienia wody (14). Między tarczowym uchwytem (14) a głowicą pomiarową (6) w korpusie (2) wykonany jest otwór odpływowy (8). Każdy z kanałów (11) ma połączenie z przynależnym mu króćcem odpływowym. Przy znanym wydatku strumienia wody (14), ilości wody z kanałów (11) ujęte w króćcach odpływowych i otworze odpływowym (8) tworzą charakterystykę dyszy zraszającej.The application concerns a device for testing sprinkler nozzles used in the mining organs of mining combines. The device (1) has a body (2) in the form of a sleeve equipped in the central part with a longitudinal cut-out (3) in the mantle. One end (2 ') is equipped with a disk holder (4), in which the tested spray nozzle is mounted, and from the other end (2 ") it is closed by a measuring head (6), inside of which control inserts (7a, 7b, 7c) Control cartridges (7a, 7b, 7c) with their conical surfaces facing the spray nozzle define edges (10) between which channels (11) are formed for water jet sprayed at various angles (14). Between disc handle (14) and a measuring head (6) in the body (2), a drainage hole (8) is made. Each of the channels (11) has a connection with its associated drainage connection. With known water flow (14), the amounts of water from the channels (11) are included in the drain pipes and drain hole (8) they form the characteristics of the spraying nozzle.
