Title
(EN) METHOD FOR CONTROLLING THE VACUUM GENERATOR^ IN A VACUUM SEWAGE SYSTEM
(FR) PROCÉDÉ DE COMMANDE DU GÉNÉRATEUR DE VIDE DANS UN SYSTÈME À VIDE D’ÉVACUATION DES EAUX USÉES
Abstract
(EN)
Method for controlling one or more vacuum generators (1) and thereby the vacuum in a vacuum sewage system, in particular controlling one or more liquid ring screw pumps in such system, including beyond the generator/s (1) one or more tubular collectors or suction pipelines (2) connected to the vacuum generator and one or more toilets, urinals, grey water sinks etc (3, 4), connected to the suction pipeline through branch pipelines (6). The rotational speed of the vacuum generator (1) is controlled on the basis of the set vacuum requirement.
(FR)
Cette invention concerne un procédé de commande d’un ou plusieurs générateur(s) de vide (1) et, par conséquent, le vide dans un système à vide d’évacuation des eaux usées. En particulier cette invention concerne la commande d’une ou de plusieurs pompes à vis à anneau liquide dans un système de ce type comprenant, mis à part le/les générateurs (1) un ou plusieurs collecteurs ou conduites d’aspiration (2) raccordés au générateur de vide, ainsi qu’un ou plusieurs toilettes, urinoirs, cuves à eaux noires (3, 4) etc., raccordés à la conduite d’aspiration par l’intermédiaire de conduites de branchement (6). La vitesse de rotation du générateur de vide (1) est commandée sur la base du vide requis.
