摘要:
Abdichtung für kolbengesteuerte Dosiereinrichtungen bei Streugeräten mit einer Dosierkammer (3), deren Austrittsöffnung (4) durch einen druckbelasteten Dosierkolben (5) abgeschlossen ist, welcher im Bedarfsfall gegen den auf ihn ausgeübten Druck durch eine Hubvorrichtung (7), z.B. einen Hubmagnet, einen Hubzylinder od. dgl. von der Austrittsöffnung (4) der Dosierkammer (3) abhebbar ist, wobei eine Dichtung am der Austrittsöffnung (4) der Dosierkammer (3) zugekehrten Ende des Dosierkolbens (5) vorgesehen ist. Zur Verbesserung der Kolbenabdichtung ist das der Austrittsöffnung (4) der Dosierkammer (3) zugekehrte Ende des Dosierkolbens (5) von einem aus gummiartigen Material, Kunststoff od. dgl. bestehenden Dichtungselement (8) umschlossen ist. Dadurch wird eine praktisch verschleißsichere Dichtung erzielt und bei einer Streuanlage nach dem Injektorprinzip als weiterer Vorteil erzielt, daß durch die Injektorfunktionsweise auf den gesamten sandzuführenden Raum ein Unterdruck erzeugt wird.
摘要:
A scattering device (1) for spreading bulk material, in particular braking sand, at railborne vehicles, with a storage container, an outlet on the storage container, a mixing device (3) which adjoins the outlet and has a mixing space (4), an inlet (5) for the supply of compressed air, and an outlet (10), leading to a discharge device (9), in the mixing device (3), wherein a suction nozzle (11) to which the discharge device (9) is connected is provided at the outlet (10), wherein the nozzle duct (12) of the suction nozzle (11) is formed by a cylindrical bore (14), wherein the length (L) of the cylindrical bore (14) within the suction nozzle (11) is at least equal to the size of the diameter (d) of the cylindrical bore (14) in the suction nozzle (11), wherein the distance (a) of the suction nozzle (11) or of the inlet opening (16) in the suction nozzle (11) to the outlet opening (7) of the inlet (5) for the supply of compressed air in the mixing device (3) is smaller than twice the size of the inside diameter (d) of the cylindrical bore (14), and wherein, in order to form a sand stairway in the mixing space (4), the suction nozzle (11) projects at the end (15) thereof that faces away from the discharge device (9) into the mixing space (4) to an extent such that that end (15) of the suction nozzle (11) which faces away from the discharge device (9) is arranged in the mixing space (4) above the outlet opening (17) of the outlet.
摘要:
The invention relates to a sanding device for a rail vehicle, said device comprising a compressed air supply (1), a first pneumatic valve (2), a second pneumatic valve (3), a pressure container (4), and a sanding nozzle (5) in a sand container. The aim of the invention is to provide a rail region (15) beneath a wheel (13) of a rail vehicle with sand from a sand container. To this end, the sand container is fed with compressed air directly from the pressure container (4), automatically pulsed compressed air being guided from the compressed air supply (1) to the pressure container (4).
