Object of the contract
Description of material skupiny.Spôsobilos? the product which is the subject of this qualification assessment is divided into two subgroups ( A and B ), which were considered different requirements spôsobilosti.Podskupina A : " Turbine bypass ( bypass ) valves and similar valves together with related systems, cooling steam ".Ventily must include the following : - pneumatic or hydraulic actuators- Accessories, such as smart positioners, position transmitter feedback, limit switches, solenoid valves, emergency manual operation, the spare tank instrumentation air - hydraulic control unit ( if applicable) by the interface with the main regulatory systémom.Chladiaci system must include : - Air and hydraulic valves control the steam temperature, equipped with all the necessaryand accessories - system of cooling water spray nozzles and injectors (cooling station ). ( Such systems can be incorporated into the thermal control valves, provided that there is a configuration ''variable cooling jets " ). Subgroup B : " Different regulatory control and pneumatic opening / closing valves ".This section includes regulatory control and pneumatic opening / zatVaraci valves príslušenstvom.prevádzkové fluids typically include supercooled liquid ( cavitation problems ), saturated or evaporating liquids ( with the problems of rapid evaporation ), saturated and superheated steam, liquid and gaseous fuels and also auxiliary liquid in všeobecnosti.Prevádzkové conditions may include increased differential pressure and high teploty.Príslušné circuit therefore comprises subsequentlyglare - condensate - Water Supply - superheated steam - hot reheating steam - cold reheating steam - auxiliary steam - drainage and venting, - Turbine collection - fuels ( gas and liquid ) - Auxiliary služby.Zákazky concern two parts which was divided product typology, which is subject to review and include the following services are included: - functional layouts and alsofeasibility and detailed planning of content delivery - demonstrate planning and control engineering and / or manufacturing activities, in particular the proper application of manufacturing technologies ( procedures, personnel and resources ) involved in the production project, with special attention being paid to projects with high technological content - plan quality management, which is to be submitted for approval - testingand checks carried out directly on the device - marking, paint, storage, treatment, protection, transportation, certification documents - Aftermarket podpora.Dodávatelia should also provide information on the status of individual planning and engineering and production activities in accordance with the procedures laid down by ENEL in the case of all individual dodávok.Hlavné technical charakteristiky.Zariadeniemust be designed to desired life of 25 rokov.Dodávate? ensure a high level of continuity of service and maintenance must be simple and reduced to minimum.Podrobnejšie technical characteristics and requirements which must be met by the supplier are specified in the technical specifications and documentation of data to be submitted for each ENEL dodávky.Nižšie include general and basic funfrictionally and manufacturing characteristics : Functional vlastnosti.Rozli?né functional aspects that apply to both parts ( except where otherwise specified) : a. flow coefficient ( Cv and Kv ) should be complied with IEC 60534-2, Part 1 to 5. The actual valve flow capacity is not the declared value deviating by more than 5 %; b. Noise level at 1 m from the valve, the equivalent ofoverloads continuous sound pressure levels ALAeq, measured and presented in accordance with ISO 1996 should not exceed the limits specified in the technical specifications Procurement (setpoints are typically 82 to 85 dBA with a tolerance of +0 dB ) over the entire operating range of the valve; c. Cavitation and lamination : in the case of incompressible fluids in the presence of high pressure differences to beonštrukcia allow a sufficient number of independent degrees of pressure drop, to maintain the liquid velocity of the thrust to the degree to which a cavitation phenomena, rapid evaporation and / or laminating erosion arise. Check valves in critical services, such as a turbine bypass ( bypass ), the cooling system of steam and feed water pump recirculation, must be multi-stage or Iabyrintové equipment. Suitable reducing the number of pressure levels must limit the speed of the liquid drain 32 m / s, total operating conditions; d. impact velocity : should be between 5 mm / s to 10 mm / s. Part A for valves it is necessary that the valves respond along its path in less than 3 p e. leak tests and functional tests also should be carried out in compliance with ISC 60534-4, class V.Charakteteristic curve and regulation range : related to the formulation and acceptance criteria, see IEC 60534-2-4; g. shut-off valves may exceptionally be equipped with electric drives. In this case, it must be built on the dashboard control motoru.Konštruk?né charakteristiky.Telesá valves should be cast or forged from a single piece and can be spherical, rotary, angle or Z - typeWith end terminations with flange or ready for welding. Bodies without end flange or inter- bodies are acceptable for class classification, which is lower than PN50. Composite body, broken bodies and welded valve bodies are unacceptable. Size bodies and pressure parts shall comply with design standards ANSI B16-34 and DIN 3840.Pokia? to the draft design, production and evaluation of conformity, the whole unit valve drive mechanism and accessories meet Directive No. PED. 97/23 / EC, which is part of the Decree. 25.2.2000.Materiály 93 of the body must be chosen not only to function but also in view of thermodynamic transformation process kvapaliny.Zvláš? reduced pressure for valves used with liquids of high pressure differenceIelmo or vyparujúcimi the liquids to be used telesávyrobené alloy Cr- Mo ( ASTM A - 217 WC9, WC6 - A217, A217 - C5 ).Okraj must usually cage (single or multiple) to the end of the rapid exchange and with balanced connection, with or without pilot balance vyváženia.Záruka pilot testing and výkonu.Všetky valves with driving mechanisms and accessories must be subjected to usledujúcim tested in accordance with those set out in the specification ENEL : workshop test - standard tests; hydraulic pressure testing valve bodies; tests seal seats, magnetic powder testing, capillary testing; X-ray tests - functional tests, such as verification of the nominal stroke test dead zone, and time travel, - special tests on request on the basis of data documentation, X-ray and ultrasound skúšky.Testy in place inštalácie.Predpokladajú the control of noise, which produce valves, control of the actuation time under load, flow capacity, for potreby.Ventily should be supplied with a certificate from the manufacturer, stating the chemical and mechanical characteristics of pressure components, together with the characteristics of pohonu.Certifikáty for testing, monitoringand materials must indicate the value recorded during the tests and their evaluation, the methods, and reference standards used postupy.Referen?né normy.Nižšie include basic reference standards : - ANSI ASME B16.34 - a complete range of IEC 60534 - Directive PED 97 / 23 / EC and Decree no. 93 of 25.2.2000.- standards EN.- standards available.
