27、ications 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 im
28、portance 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 the Tendering documents but not vice versa. As a general rule the word “Tenderer” should be con
29、fined 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 is
30、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 hydraul
31、ic 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 Pelton turbine specificati
32、ons include technical specifications for the following: Design conditions: Project arrangement, hydraulic conditions, specified conditions, mode of operation, generator characteristics, synchronous condenser characteristics, transient behaviour data, stability of the system, noise, vibration, pressu
33、re fluctuations and safety requirements. Technical performance and other guarantees: power; discharge (if required); efficiency; maximum momentary pressure; minimum momentary pressure; maximum momentary overspeed; maximum steady-state runaway speed; cavitation pitting; hydraulic thrust; maximum weig
34、hts and dimensions for transportation, erection and maintenance. Mechanical design criteria: design standards, stresses and deflections and special design considerations (earthquake acceleration, etc.). Design documentation: Contractors input needed for the Employers design, Contractors drawings and
35、 data, Contractors review of the Employers design and technical reports by Contractor. Materials and construction: material selection and standards, quality assurance procedures, shop methods, corrosion protection and painting. Shop inspection and testing: general requirements and reports, material
36、tests and certificates, dimensional checks, shop assembly and tests. Fixed/embedded components: manifold for multi-jet turbines and turbine housing. Stationary/removable components: branch pipe for horizontal turbines, upper turbine housing (if not embedded), turbine cover, brake jet assembly). Inje
37、ctor and deflector systems: nozzles, needles, needle servomotors, deflectors or cut-in deflectors, deflector servomotors, links, needle-deflector combining mechanism and oil piping. Rotating parts, bearings and seals: runner, main shaft, guide bearing with oil supply, oil/water cooler, shaft seal. T
38、hrust bearing (when part of the hydraulic machine supply): bearing support, thrust block, rotating ring, thrust bearing pads and pivots, oil sump with oil supply (common with guide bearing, if any), oil/water coolers, instrumentation. Miscellaneous components: walkways, lifting fixtures, special too
39、ls, standard tools, turbine pit hoist, nameplate, runner inspection platform (if required). Auxiliary systems: bearing lubrication system (if required), tailwater air admission system, turbine pit drainage (if required), turbine housing ventilation, tailwater depression (if required). Instrumentatio
40、n: controls, indication and protection. Spare parts: basic spare parts.

Site installation and commissioning tests: I
41、nstallation procedures and commissioning tests. Field acceptance tests: scope of field tests, 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 tech
42、nical specifications for the control system, or high-pressure side valves which, at the Employers option, may be included in the Tendering documents for the Pelton turbine or may be specified in separate Tendering documents. Chapter 6 (technical specifications) of the Tendering documents should be a
