Abstract

This is a pump type which can be designated as a disc-plate pump. This is because the support element, like the conveying plate moving therein, is disc-shaped. This pump can be operated as a liquid pump and an air pump. Owing to the special construction of the disc-plate pump there are only small volume losses due to fitted conveying elements, because these elements take up little room in the disc-plate pump. Distinctive characteristics of the pump are the disc-shaped design of the conveying elements and of the pump casing, the positioning of the conveying elements away from the centre, and the compensation of the diameter differences resulting therefrom by inserting springs which bridge these differences. The pump is self-priming and shows virtually no drop in performance against a high back pressure. Thus a pump having the dimensions 140 . 100 has a delivery rate of as much as 220 l per minute at 520 rpm. The pump can be operated while turning in either direction.

Description

Beschreibungdescription

Es handelt sich hierbei um eine Pumpenart für Flüssigkeiten und Gase.It is a type of pump for liquids and gases.

Durch die besondere Gestaltung des Pumpenelementes ( 2 ) gegenüber anderen Drehschieberpumpen kann diese Pumpe auf für dickflüssige Medien oder Medien mit Fremdkörpern eingesetzt werden. Durch die besondere Anordnung und Form der Ein- und Auslässe ist nur eine geringe Verbindungszeit zwischen Ein- und Auslaß. Die Pumpe kann nicht trockenlaufen, weil sie nur die Differenz zwischen Druck- und Saugraum an Flüssigkeit abgibt.Due to the special design of the pump element (2) opposite Other rotary vane pumps can use this pump for viscous media or media be used with foreign bodies. Due to the special arrangement and shape of the and outlets there is only a short connection time between inlet and outlet. the The pump cannot run dry because it is only the difference between the pressure and suction space releases in liquid.

Die Pumpe ist selbstansaugend und kann mit hohen Drücken gefahren werden.The pump is self-priming and can run at high pressures will.

Claims (3)

Patentansprüche 1. Drehschieberpumpen sind dadurch gekennzeichnet, daß sich in einem kreisförmigen Gehäuse ( 1 ) ein exzentrisch gelagertes Trägerelement ( 2 ) befindet, in dem sich zwei um 1800 versetzte, in einem Schlitz des Trägerelementes ( 2 ) befindenden Scheiben ( 3 ) bewegen, die mittels einer Feder ( 4 ) gegen das Gehäuse ( 1 ) gedrückt werden.Claims 1. Rotary vane pumps are characterized by that in a circular housing (1) there is an eccentrically mounted carrier element (2), in which there are two offset by 1800, in a slot in the support element (2) move the disks (3) that are located against the Housing (1) are pressed. Im Schnitt zur Drehachse ist die Breite des Trägerelementes ( 2 ) etwa halb so groß wie seine Länge. In the section to the axis of rotation is the width of the carrier element (2) about half its length. 2. Die radiale Bogenlänge von Ein- und Auslaß bilden mit der Drehachse des Trägerelementes ( 2 ) den gleichen Winkel, wobei der Einlaß ( 5 ) unterhalb der Mittelachse und der Auslaß ( 6 ) oberhalb der Mittelachse angeordnet ist.2. The radial arc length of the inlet and outlet form with the axis of rotation of the carrier element (2) the same angle, with the inlet (5) below the central axis and the outlet (6) is arranged above the central axis. 3. Ein Trockenlaufen der Pumpe bei Flüssigkeiten ist nicht möglich, weil die Pumpe nur die Differenz von Saug- und Druckraum abgibt.3. It is not possible for the pump to run dry with liquids. because the pump only emits the difference between the suction and pressure chambers.
