(Main)Pelton hydraulic turbines - Model acceptance tests
Pelton hydraulic turbines - Model acceptance tests
IEC 63461:2024 applies to laboratory model tests of any type of Pelton hydraulic turbine with unit power greater than 5 MW. It contains the rules governing test conduct and provides measures to be taken if any phase of the tests is disputed. The main objectives of this document are: - to define the terms and quantities used; - to specify methods of testing and of measuring the quantities involved, in order to ascertain the hydraulic performance of the model; - to specify the methods of computation of results and of comparison with guarantees; - to determine if the contract guarantees that fall within the scope of this document have been fulfilled; - and to define the extent, content and structure of the final report. Full application of the procedures herein described is not generally justified for machines with smaller power. Nevertheless, this document can be used for such machines by agreement between the purchaser and the supplier.
Hydraulische Pelton Turbinen - Modellabnahmeprüfungen
Turbines Pelton - Essais de réception sur modèle
IEC 63461:2024 s’applique aux essais de modèles de laboratoire de tout type de turbine Pelton d’une puissance unitaire supérieure à 5 MW. Il fixe les règles de conduite de ces essais et spécifie les mesures à prendre en cas de contestation d’une phase quelconque des essais. Les principaux objectifs du présent document sont les suivants: - définir les termes et les grandeurs utilisés; - spécifier les méthodes d'essai et de mesure des grandeurs concernées, afin de déterminer les performances hydrauliques du modèle; - spécifier les méthodes de calcul des résultats et de comparaison avec les garanties; - déterminer si les garanties contractuelles qui relèvent du domaine d’application du présent document sont respectées; - et définir l’étendue, le contenu et la structure du rapport final. L’application intégrale des procédures décrites dans le présent document ne se justifie généralement pas pour les machines de puissance inférieure. Néanmoins, le présent document peut être utilisé pour de telles machines après accord entre l’acheteur et le fournisseur.
Peltonove vodne turbine - Prevzemni preskusi modela (IEC 63461:2024)
Standard IEC 63461:2024 se uporablja za laboratorijske preskuse modela Peltonove vodne turbine katere koli vrste z močjo enote, večjo od 5 MW. Vsebuje pravila, ki urejajo izvajanje preskusov, in določa ukrepe, ki jih je treba izvesti v primeru sporov glede ene od faz preskusov.
Glavni namen tega dokumenta je:
– opredelitev izrazov in količin, ki se uporabljajo;
– določitev metod za preskušanje in merjenje vključenih količin, da se opredeli hidravlična zmogljivost modela;
– določitev metod za izračun rezultatov in primerjavo z jamstvi;
– ugotovitev, ali so pogodbena jamstva, ki spadajo na področje uporabe tega dokumenta, izpolnjena; ter
– določitev obsega, vsebine in strukture končnega poročila.
Celotna uporaba postopkov, opisanih v tem dokumentu, na splošno ni utemeljena za stroje z manjšo močjo. Kljub temu pa je mogoče po dogovoru med kupcem in dobaviteljem ta dokument uporabiti tudi za take stroje .
