Description
<Desc/Clms Page number 1>
Dickstoff- bzw. Mörtelpumpe
EMI1.1
<Desc/Clms Page number 2>
Es häuses -14 angp. flanscht, welcher den eigentlichen Arbeitsraum 18 der Pumpe sowie das Einlassventil 16 und das Auslassventil 17 enthält. In der gezeichneten Stellung schliesst das Einlassventil, und die Dickstoffe werden aus dem Arbeitsraum 18 bei geöffnetem Auslassventil 17 in Pfeilrichtung 22 in die Auslassleitungen 19 gefördert.
Beispielsweise im rechten Winkel zum Arbeitskolben 15 ist ein Ausweichkolben 20 angeordnet, der im Zylinder 3 hin-und hergleiten kann. Der Zylinder 3 des Ausweichkolbens 20 ist über eine Druckluftleitung 23 mit einem Kompressionsraum 24 verbunden. Der Kompressionsraum 24 ist mit einem Druckmesser 26 ausgestattet und steht mit einem Ventil 25 in Verbindung, das nach der Aussenluft hin öffnet. Durch den Kompressionsraum 24 lässt sich die Gegenkraft auf den Ausweichkolben 20 genau einregulieren. Die eingestellte Gegenkraft ist dann am Druckmesser 26 ablesbar. Die Gegenkraft wird grösser oder klei- ner, je nachdem, welche Luftmenge im Kompressionraum 24 sich befindet bzw. wieviel Luft durch Öffnen des Ventils 25 nach aussen abströmen kann.
Der Zylinderraum 28 ist mit einer Flüssigkeit gefüllt, welche den Druck des Arbeitskolbens 15 hydraulisch auf die Membran 27 und den Ausweichkolben 20 überträgt. Der Ausweichkolben 20 ist, wie schematisch angedeutet, mittels einer Stange 29 geführt.
Als Anwendung der Erfindung sind alle Möglichkeiten zu bezeichnen, bei denen Dickstoffe aus meh-
EMI2.1
Druckleitungen entnommen werden sollen1. Dickstoff- bzw. Mörtelpumpe mit einem Ausweichkolben, bei welcher der Arbeitsraum durch eine Membran abgeschlossen ist und die Druckübertragung durch eine Zwischenflüssigkeit erfolgt, dadurch gekennzeichnet, dass der Ausweichkolben (20) über eine Druckluftleitung mit einem Kompressionsraum (24) und der Kompressionsraum durch ein Ventil (25) mit der Aussenluft verbunden ist.

Thick matter or mortar pump
EMI1.1

It houses -14 angp. flanges, which contains the actual working space 18 of the pump as well as the inlet valve 16 and the outlet valve 17. In the position shown, the inlet valve closes, and the thick matter is conveyed from the working chamber 18 with the outlet valve 17 open in the direction of arrow 22 into the outlet lines 19.
For example, at a right angle to the working piston 15, an escape piston 20 is arranged, which can slide back and forth in the cylinder 3. The cylinder 3 of the bypass piston 20 is connected to a compression chamber 24 via a compressed air line 23. The compression space 24 is equipped with a pressure gauge 26 and is connected to a valve 25 which opens to the outside air. The counterforce on the deflecting piston 20 can be precisely regulated by the compression chamber 24. The counterforce set can then be read on the pressure gauge 26. The counterforce becomes greater or lesser, depending on the amount of air in the compression space 24 or how much air can flow outwards by opening the valve 25.
The cylinder space 28 is filled with a liquid which hydraulically transfers the pressure of the working piston 15 to the diaphragm 27 and the bypass piston 20. As indicated schematically, the avoidance piston 20 is guided by means of a rod 29.
As an application of the invention, all possibilities are to be designated in which thick matter from meh-
EMI2.1
Pressure lines are to be removed 1. Thick matter or mortar pump with an escape piston, in which the working space is closed off by a membrane and the pressure is transmitted through an intermediate liquid, characterized in that the escape piston (20) via a compressed air line with a compression space (24) and the compression space through a valve (25) is connected to the outside air.
