27、cations is to describe the specific technical requirements for the hydraulic machine for which the Tendering documents (TD) are being issued. To achieve clarity and to avoid confusion in contract administration, the Employer should not specify anything in the technical specifications which is of imp
28、ortance only to the preparation of the tender. Such information and instructions should be given only in the instructions to Tenderers (ITT). Accordingly, the 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 c
29、onfined in use only to TD Chapter 1 “Tendering requirements”; elsewhere the term “Contractor” should be used. Special attention should be given to items of a project specific nature such as materials, protective coating systems, mechanical piping systems, electrical systems and instrumentation. It i
30、s 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, detailed technical standards should be specified in TD Chapter 5 “General requirements”. Technical specifications for the various types of hydra
31、ulic machines included in this guide are provided in the following parts: Francis turbines (Part 2); Pelton turbines (Part 3); Propeller and Kaplan turbines (Part 4); Tubular turbines (Part 5); Pump-turbines (Part 6); Storage pumps (Part 7). The guidelines for preparation of tubular turbine specific
32、ations include technical specifications for the following: Design conditions: Project arrangement, hydraulic conditions, mode of operation, generator characteristics, transient behaviour data, stability of the system, noise, vibration, pressure fluctuations and safety requirements. Technical perform
33、ance and other guarantees: power; discharge; efficiency; maximum momentary pressure; minimum momentary pressure; maximum momentary overspeed; maximum steady-state runaway speed; cavitation pitting; hydraulic thrust; maximum weights and dimensions for transportation, erection and maintenance. Mechani
34、cal design criteria: design standards, stresses and deflections and special design considerations. Design documentation: Contractors input needed for the Employers design, the Contractors drawings and data, Contractors review of the Employers design and technical reports by Contractor. Materials and
35、 construction: material selection and standards, quality assurance procedures, shop methods and personnel, corrosion protection and painting. Shop inspection and testing: general requirements and reports, material tests and certificates, dimensional checks, shop assembly and tests. Fixed/embedded co
36、mponents: generator hatch cover or pit, stay ring, discharge ring (if any), draft tube, draft tube liner foundations anchorage, upstream and downstream pressure taps and pipes. Stationary/removable components: bulb nose, generator access shaft inner and outer guide rings and guide vanes. Regulating
37、apparatus: servomotor, counterweight, connecting rods, regulating ring, guide vane linkage, system, guide vane overload protection and locking devices. Rotating parts, bearings and seals: runner, main shaft, guide bearing, main shaft seal, oil head and runner blade regulation system with servomotor
38、assembly with oil supply, linkage system, crosshead and oilhead. Thrust and counter-thrust bearing: bearing support, thrust collar and counter-thrust bearing pads and rings, oil sump and instrumentation. Gear box: gear box and related components. Miscellaneous components: walkways, platforms, liftin
39、g fixtures, special tools, standard tools and nameplate. Auxiliary systems: water supply to main shaft seal, turbine drainage, lubrication-guide vane regulating system, and oil supply to bearings. Instrumentation: controls, indication and protection. Spare parts: basic spare parts. Model acceptance
40、tests: test requirements. Site installation and commissioning test: installation procedures and commissioning.

41、e 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 IEC 61366-1. The example does not include technical specifications for the control system, relief valves, or high and low pressure sli
42、de 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. Chapter 6 (technical specifications) of the Tendering documents should be arranged as follows: 1 Scope This technical report, referred to herein as
