The UK participation in its preparation was entr

3、usted to Technical Committee MCE/15, Hydraulic turbines, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor relate

4、d international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered

5、as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.

To achieve cla

25、rity and to avoid confusion in contract administration, the Employer should not specify anything in the technical specifications which is of importance only to the preparation of the tender. Such information and instructions should be given only in the instructions to Tenderers (ITT). Accordingly, t

26、he ITT may refer to other chapters and sections of the Tendering documents but not vice versa. As a general rule the word “Tenderer” should be confined in use only to TD Chapter1 “Tendering requirements”; elsewhere the term “Contractor” should be used. Special attention should be given to items of a

27、 project specific nature such as materials, protective coating systems, mechanical piping systems, electrical systems and instrumentation. It is common for the Employer to use technical standards for such items which would apply to all contracts for a particular project or projects. In this event, d

28、etailed technical standards should be specified in TD Chapter5 “General requirements”. Technical specifications for the various types of hydraulic machines included in this guide are provided in the following parts: Francis turbines (Part 2); Pelton turbines (Part 3); Propeller and Kaplan turbines (

29、Part 4); Tubular turbines (Part 5); Pump-turbines (Part 6); Storage pumps (Part 7). The guidelines for preparation of tubular turbine specifications include technical specifications for the following: Design conditions: Project arrangement, hydraulic conditions, mode of operation, generator characte

30、ristics, transient behaviour data, stability of the system, noise, vibration, pressure fluctuations and safety requirements. Technical performance and other guarantees: power; discharge; efficiency; maximum momentary pressure; minimum momentary pressure; maximum momentary overspeed; maximum steady-s

34、re taps and pipes. Stationary/removable components: bulb nose, generator access shaft inner and outer guide rings and guide vanes. Regulating apparatus: servomotor, counterweight, connecting rods, regulating ring, guide vane linkage, system, guide vane overload protection and locking devices. Rotati

35、ng parts, bearings and seals: runner, main shaft, guide bearing, main shaft seal, oil head and runner blade regulation system with servomotor assembly with oil supply, linkage system, crosshead and oilhead. Thrust and counter-thrust bearing: bearing support, thrust collar and counter-thrust bearing

36、pads and rings, oil sump and instrumentation. Gear box: gear box and related components. Miscellaneous components: walkways, platforms, lifting fixtures, special tools, standard tools and nameplate. Auxiliary systems: water supply to main shaft seal, turbine drainage, lubrication-guide vane regulati

37、ng system, and oil supply to bearings. Instrumentation: controls, indication and protection. Spare parts: basic spare parts. Model acceptance tests: test requirements. Site installation and commissioning test: installation procedures and commissioning.BSIEC61366-5:1998 2 BSI 05-1999 Field acceptance

38、 tests: scope of field test scope and reports and inspection of cavitation pitting. An example of the proposed table of contents for Tendering documents for a Francis turbine is given in Annex A of IEC61366-1. The example does not include technical specifications for the control system, relief valve

39、s, or high and low pressure slide valves or gates which, at the Employers option, may be included in the Tendering documents for the turbine or may be specified in separate documents. Chapter6 (technical specifications) of the Tendering documents should be arranged as follows: 1 Scope This technical
