Rotodynamic pumps - Design of pump intakes - Recommendations for installation of pumps

1.1   This technical Report contains recommendations for the design of pump intakes and the installation of pumps.
As far as possible, these recommendations should be adhered to in order to obtain correct operation of the plant.
These recommendations are applicable regardless of the flow rate of the plant:
   plant which works with clear water (or relatively unclouded) and relatively non-aerated water or any other liquid having physical and chemical properties which are similar to those of water;
NOTE   This document nevertheless contains several general recommendations for operation with cloudy (or very cloudy) water.
   pumping plant which has its own floor.
1.2   This document deals with various intake configurations:
   Clause 3 contains recommendations which apply to intakes with vertical suction inlet;
   Clause 4 contains recommendations applicable to intakes with top suction inlet;
   Clause 5 contains recommendations applicable to intakes with floor suction inlet;
   Clause 6 contains recommendations applicable to intakes with side-wall suction inlet.

Pompes rotodynamiques - Conception des ouvrages d'aspiration - Recommandations d'installation des pompes

1.1 Le présent Rapport Technique donne des recommandations pour la conception des ouvrages
d’aspiration et l’installation des pompes dans ces ouvrages.
Il convient que ces recommandations soient, autant que possible, respectées pour obtenir un bon
fonctionnement de l’installation.
Ces recommandations sont valables quel que soit le débit de l’installation :
⎯ pour des installations fonctionnant en eau claire (ou peu chargée) et relativement peu aérée, ou tout
autre liquide de propriétés physiques et chimiques voisines de celles de l’eau ;
NOTE Le présent document comporte cependant quelques recommandations générales, pour les cas de
fonctionnement en eau chargée (ou fortement chargée).
- pour des installations de pompage comportant leur propre radier.
1.2 Le présent document traite de diverses configurations des ouvrages d’aspiration :
- l’Article 3 donne les recommandations applicables en cas d’ouvrage d’aspiration avec orifice d’aspiration
vertical ;
- l’Article 4 donne les recommandations applicables en cas d’ouvrage d’aspiration avec orifice d’aspiration
en « plafond » ;
- l’Article 5 donne les recommandations applicables en cas d’ouvrage d’aspiration avec orifice d’aspiration
en radier ;
- l’Article 6 donne les recommandations applicables en cas d’ouvrage d’aspiration avec orifice d’aspiration
en paroi latérale.

Centrifugalne črpalke - Načrtovanje dovodov - Priporočila za vgradnjo črpalk

To tehnično poročilo vsebuje priporočila za načrtovanje dovodov in vgradnjo črpalk. Za pravilno obratovanje črpalke se je treba teh priporočil čim bolj držati. Ta priporočila veljajo ne glede na pretok črpalke: - črpalka, ki deluje s čisto vodo (oziroma sorazmerno nemotno) in sorazmerno neaerirano vodo ali drugo tekočino, ki ima vodi podobne fizikalne in kemične lastnosti; - črpalni obrat z lastnim dnom. Ta dokument obravnava različne konfiguracije dovodov: - Klavzula 3 vsebuje priporočila, ki veljajo za dovode z navpičnim sesalnim dotokom; - Klavzula 4 vsebuje priporočila, ki veljajo za dovode s sesalnim dotokom od zgoraj; - Klavzula 5 vsebuje priporočila, ki veljajo za dovode s sesalnim dotokom od spodaj; - Klavzula 6 vsebuje priporočila, ki veljajo za dovode s stranskim sesalnim dotokom.
