Abstract

Η εφεύρεση αναφέρεται σε μέθοδο για τη ρύθμιση και τη λειτουργία ενός συστήματος ανύψωσης υγρών λυμάτων, το οποίο είναι εξοπλισμένο με φυγοκεντρική αντλία και το οποίο χρησιμεύει για τη μεταφορά υγρών λυμάτων που περιέχουν ή δεν περιέχουν περιττώματα και, εάν είναι κατάλληλο, επιφανειακού νερού σε ένα σύστημα αγωγών, με τα υγρά λύματα να μεταφέρονται μέσω εξαρτήματος μη επιστροφής (6, 11), ειδικότερα μιας επίπεδης βαλβίδας μη επιστροφής, σε μια σωλήνωση (4) που συναντάται κατά προτίμηση κάτω από ένα επίπεδο αντίθλιψης (1) που ορίζεται για το σύστημα αγωγών (5), καθώς και με μια ελάχιστη ταχύτητα ροής που έχει καθοριστεί για τη μεταφορά. Η προηγούμενη περίπλοκη σχεδίαση ενός τέτοιου συστήματος ανύψωσης υγρών λυμάτων, η οποία συνεπαγόταν τον κίνδυνο λανθασμένου υπολογισμού των διαστάσεων, καθίσταται περιττή από την εφεύρεση ως αποτέλεσμα μιας μεθόδου που ξεκινά από ένα έτοιμο για εγκατάσταση σύστημα ανύψωσης και σε αυτό, πρώτα προσδιορίζονται οι ταχύτητες περιστροφής της φυγοκεντρικής αντλίας (Β) που είναι σημαντικές για τα διάφορα επισημασμένα σημεία λειτουργίας με τη βοήθεια ενός ηλεκτρικού μοτέρ (9) εξοπλισμένου με έναν προγραμματιζόμενο μετατροπέα συχνοτήτων (10) και το οποίο οδηγεί τη φυγοκεντρική αντλία (Β) και αυτές οι ταχύτητες περιστροφής, μαζί με τα δεδομένα που προκύπτουν από αυτές, αποθηκεύονται σε μια κεντρική μονάδα που ελέγχει το σύστημα ανύψωσης υγρών λυμάτων και χρησιμοποιούνται ως βάση για την περαιτέρω λειτουργία (σχήμα 3).The invention relates to a method for regulating and operating a sewage disposal system, fitted with a centrifugal pump, which serves to transport waste water containing or not containing drains and, if appropriate, surface water to a system. conduits, with the liquid sewage being conveyed through a non-returning fitting (6, 11), in particular a flat non-returning valve, to a pipe (4) preferably located below a level of pressure (1) specified for the system section of ducts (5), as well as at a minimum flow rate specified for transport. The prior complicated design of such a liquid sewage lifting system, which entailed the risk of incorrect dimensional calculation, is rendered redundant by the invention as a result of a method starting from a ready-to-install lifting system in which the rotational speeds of rotation are first determined. pumps (B) which are important for the various marked operating points by means of an electric motor (9) equipped with a programmable frequency converter (10) and which drives the centrifugal pump (B) and these rotational speeds, together with the data derived therefrom, are stored in a central unit that controls the sewage disposal system and are used as a basis for further operation (Figure 3).
