Description
Hydraulische Sprengpumpe mit Preßkolben und darin angeordneter IZückholfeder Hydraulische Sprengpumpen mit Preßkolben und darin angeordneter Rückholfeder für den Kolben sind bereits bekannt, jedoch entstanden hierbei schädliche Luftkissen in den Hohlräumen der Preßkolben.Hydraulic blasting pump with plunger and return spring arranged in it Hydraulic explosive pumps with plungers and a return spring for the pistons are already known, but this created harmful air cushions in the cavities of the plunger.
Ferner sind Kolben für Brennkraftmaschinen bekannt, die aus einem Eisen- oder Stahlmantel mit Leichtmetallkern zwecks Ersparnisse an Gewicht, Werkstoff und Arbeitskraft bestehen.Furthermore, pistons for internal combustion engines are known, which consist of a Iron or steel jacket with a light metal core to save weight and material and manpower exist.
Sind im Sprengzylinder der Sprengpumpe Luftkissen vorhanden, so sind dieselben bei einem Bruch oder plötzlichen Undichtwerden eines Teiles der Sprengvorrichtung für die Bedienungsmannschaft gefährlich.If there are air cushions in the blasting cylinder of the blasting pump, then there are the same in the event of a breakage or sudden leakage of part of the explosive device dangerous for the operating crew.
Abb. i zeigt den senkrechten Längsschnitt eines Druckzylinders mit einem senkrechten und einen tun go° versetzten Druckkolben.Fig. I shows the vertical longitudinal section of a printing cylinder with one vertical and one do go ° offset plunger.
Abb. ä zeigt einen sen'krechtdn Querschnitt des Druckzylinders mit Druckkolben.Fig. Ä shows a vertical cross-section of the printing cylinder Plunger.
Bei der neuen Sprengvorrichtung sind zwecks Vermeidung von schädlichen Luftkissen sowohl der hohle zylindrische Pumpenkörper a zwischen seinen Wandungen c als auch die hohlen Preßkolben b mit einem Leichtmetall ausgefüllt, und zwar die letzteren derart, daß auch der innere Hohlraum der die Preßkolben b mit dem Pumpenkörper a verbindenden. Feder f mit einem Kern ausgefüllt ist, so daß die Hohlräume zur Bildung von schädlichen Luftkissen auf ein Mindestmaß beschränkt sind.With the new explosive device are to avoid harmful Air cushion both the hollow cylindrical pump body a between its walls c and the hollow plunger b filled with a light metal, namely the the latter in such a way that the inner cavity of the plunger b with the pump body a connecting. Spring f is filled with a core, so that the cavities for Formation of harmful air cushions are kept to a minimum.
Die eng gewundene Zugfeder f hat den Zweck, den Preßkolben U gegen Herausfallen zu sichern und nach beendeter Sprengung hereinzuholen, sie ist mit ihrem oberen Ende durch einen Bolzen , befestigt; mit ihrem unteren Ende wird die Feder f durch eine gemeinsame Aufhängevorrichtung e mit dem Pumpenkörper rt verbunden. Die Auflt@ingestangc e wird durch den etwas größer im Durchmesser gehaltenen Wasserzuführungskanal f geführt und hat nur eine Abdichtungsschraube h, -was bei den hohen Drücken von großer Wichtigkeit ist.The tightly wound tension spring f has the purpose of the plunger U against To secure it from falling out and to bring it in after the demolition is finished, it is with its upper end fixed by a bolt; with its lower end becomes the Spring f is connected to the pump body rt by a common suspension device e. The opening is made possible by the slightly larger diameter water supply channel f and has only one sealing screw h, -what at the high pressures of is of great importance.
Wie aus Abb. i zu ersehen ist, können die Pi-eßkolben ti um etwa go" gegeneinander versetzt angeordnet sein; bei dem Pumpenkörper a mit zwei Reihen um go' versetzter Preßkolben U wird beim Einsetzen des Pumpenkörpers in das Bohrloch. der Rücken des Pumpenkörpers gegen das Hangende gerichtet, so daß die um go' versetzten Preßkolben b gegen das Flöz bzw. Schram gerichtet sind.As can be seen from Fig. I, the Pi-Eßkolben ti can go about " be arranged offset from one another; in the case of the pump body a with two rows go 'offset plunger U is when inserting the pump body into the borehole. the back of the pump body is directed against the hanging wall, so that the to go 'offset Plunger b are directed against the seam or Schram.
Somit wirken die Druckkräfte der um go° versetzten Preßkolben nach zwei Seiten, sowohl nach dem Hangenden als auch nach dem Schram hin, wobei das Flöz vom Handenden gelöst wird, wodurch eine Mehrleistung eintritt.Thus, the pressure forces of the plunger offset by go ° continue to act two sides, both towards the hanging wall and towards the Schram, whereby the seam is released from the end of the hand, whereby an additional performance occurs.
