Abstract

The piston vacuum pump (1) is designed to give stepless control of the delivery flow. The stepless control of the pump action is achieved by a worm drive. The worm drive is mounted eccentrically to the axis of the drive shaft. USE/ADVANTAGE - Vacuum pump for the chemical industry which avoids sealing and cavitation problems.

Description

Es handelt sich um eine Erfindung-Pumpe mit stufenloser Regelung der Fördermenge. Das ist eine Art Kolbenvakuumpumpe mit drehbarem Rotor und pulsierendem Kolben. Es sind solche Pumpen bekannt, die auf diesem Prinzip arbeiten. Bei denen wird die Regelung der Fördermenge entweder durch eine Veränderung der Drehzahl der Welle, oder durch die Veränderung des Querschnitts des Saugerohrs und Förderrohrs verwirklicht.It is an invention pump with stepless control the flow rate. It is a kind of piston vacuum pump with a rotating one Rotor and pulsating piston. Such pumps are known who work on this principle. In which the regulation of Delivery rate either by changing the speed of the Wave, or by changing the cross section of the suction tube and conveyor pipe realized.

Die Veränderung der Drehzahl erfordert einen Elektromotor mit variabler Drehzahl.Changing the speed requires an electric motor with variable speed.

Die Regelung der Fördermenge durch das Anlehnen des Saugerohrs oder Förderrohrs führt zu unerwünschten Erscheinungen wie das Saugen der Luft durch die Dichtung und Kawitation in erstem Fall, oder das Erwärmen des Gehäuses und Ausfluß der Flüssigkeit durch die Dichtung im zweiten Fall.The regulation of the delivery rate by leaning against the suction tube or conveyor pipe leads to undesirable phenomena like that Sucking the air through the seal and kawitation in the first case, or the heating of the housing and outflow of the liquid the seal in the second case.

Mit dieser Erfindung werden die o. g. Mängel beseitigt durch eine Einrichtung zu stufenloser Regelung der Fördermenge von 0 bis maximal.With this invention, the above-mentioned. Defects eliminated by a facility for stepless regulation of the delivery rate from 0 to maximum.

Die Fördermenge kann ganz genau eingestellt werden.
Anwendung: chemische Industrie
Technische Daten: Fördermenge Q=4L (min.) bei 1000 m-1.
Förderhöhe H=40 m.The delivery rate can be set very precisely.
Application: chemical industry
Technical data: Flow rate Q = 4L (min.) At 1000 m -1 .
Delivery head H = 40 m.
