Abstract

A pump for sludge, sand and gravel has two pistons (3) fitted to a vertical pump shaft (2) and with two floating disc valves (7). The pistons operate inside a housing (1) with an entry flap (4) at the bottom. As the pistons are drawn up water trapped between the pistons creates a temporary water piston to generate a higher suction effect. The valve discs have sufficient clearance from the pump chamber wall to provide an unrestricted downward stroke without a clogging effect.

Description

Kiespumpen normaler Bauart haben am Kolben ein Ventil, daß beim Absenken der Kolbenstange und des Kolbens öffnet, um Luft oder Wasser aus dem unteren Teil der Kiespumpe aufsteigen zu lassen, um ein schnelleres Absinken der Kolbenstange und des Kolbens zu erreichen. Diese Ventile setzen sich gerne mit Sand oder kleinen Steinen zu. Dann sinkt der Kolben nur noch ganz langsam oder gar nicht mehr ab. Oder das Ventil bleibt geöffnet und beim Aufziehen der Kolbenstange und Kolbens reicht das Vakuum zwischen Kolben und Bodenklappe nicht aus, um Kies, Sand oder Schlamm in das Pumpengehäuse zu ziehen. Des weiteren haben normale Kiespumpen ein oder zwei feststehende Dichtungen, die bei einer Beschädigung der Kolbenstange nicht mehr richtig abdichten.Have normal type gravel pumps a valve on the piston that at Lowering the piston rod and the piston opens to air or water to rise from the lower part of the gravel pump to one to achieve faster sinking of the piston rod and the piston. These valves tend to clog with sand or small stones. Then the piston sinks only very slowly or not at all from. Or the valve remains open and when the piston rod and piston are pulled up, the vacuum is sufficient between the piston and the bottom flap to avoid gravel, sand or mud into the pump housing to draw. Furthermore, normal gravel pumps have one or two fixed ones Seals in the event of damage no longer properly seal the piston rod.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Kiespumpe zu bauen, die auch ohne Ventil zuverlässig arbeitet. Auch dann noch, wenn es zu einer leichten Beschädigung der Kolbenstange (2) gekommen ist und die nach dem Aufziehen der Kolbenstange (2) und Kolben (3) diese auch schnell wieder absinken lässt.The invention specified in protection claim 1 is based on the problem of building a gravel pump that works reliably even without a valve. Even if there is slight damage to the piston rod ( 2 ) has come and that after pulling the piston rod ( 2 ) and piston ( 3 ) it can quickly drop again.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen (Doppelkolben zwei übereinander stehende Kolben und schwimmend gelagerte Dichtungen) gelöst.This problem is with the protection claim 1 listed Characteristics (double piston two on top of each other standing pistons and floating seals).

Mit der Erfindung wird erreicht, daß ein sehr hohes Vakuum zwischen Kolben (3) und Bodenklappe (4) entsteht weil beide Scheibendichtungen (7) unabhängig (weil schwimmend gelagert) von einander arbeiten und sich dadurch auch Wasser zwischen beiden Kolben (3) ansammelt und ein noch höheres Vakuum beim Aufziehen der Kolbenstange (2) und Kolben (3) entstehen lässt.With the invention it is achieved that a very high vacuum between pistons ( 3 ) and bottom flap ( 4 ) arises because both disc seals ( 7 ) work independently of each other (because they are floating) and there is also water between the two pistons ( 3 ) accumulates and an even higher vacuum when pulling up the piston rod ( 2 ) and piston ( 3 ) creates.

Das schnelle und unkomplizierte Absinken der Kolbenstange (2) und Kolben (3) wird erreicht durch die voneinander unabhängig schwimmend gelagerten Dichtungen, die genügend Abstand zur Innenwand des Pumpengehäuses (1) haben, um vom Pumpenboden (5) kommendes Wasser gleichmäßig aufsteigen zu lassen.The fast and uncomplicated lowering of the piston rod ( 2 ) and piston ( 3 ) is achieved by the independently floating seals, which are sufficiently far from the inner wall of the pump housing ( 1 ) from the pump bottom ( 5 ) to let incoming water rise evenly.
