Cavitation pitting evaluation in hydraulic turbines, storage pumps and pump-turbines -- Part 2: Evaluation in Pelton turbines

Cavitation pitting evaluation in hydraulic turbines, storage pumps and pump-turbines -- Part 2: Evaluation in Pelton turbines

This standard serves as a basis for the formulation of guarantees on cavitation pitting on Pelton turbine runners. It also provides a basis for the measurement and evaluation of the amount of cavitation pitting on Pelton turbine runners of a given turbine, which is defined in the contract by power, specific hydraulic energy of machine (head), rotational speed, material, operation etc. Guarantees which restrict the extent of caviation pitting and drop erosion on Pelton turbies at the end of an operating period specified in the contract are necessary when the pitting is expected in all or in some operating ranges.

Evaluation de l'érosion de cavitation dans les turbines, les pompes d'accumulation et les pompes-turbines hydrauliques -- Partie 2: Evaluation dans les turbines Pelton

La présente norme constitue la base de la formulation des garanties d'érosion de cavitation des roues des turbines Pelton. Elle traite aussi de la mesure et de l'évaluation de l'importance de cette érosion pour les roues d'une turbine donnée caractérisée contractuellement par sa puissance, son énergie hydraulique massique (chute), sa vitesse de rotation, la nature des matériaux, les conditions de fonctionnement, etc. Des garanties, qui limitent l'étendue de l'érosion par la cavitation et par l'impact de jet dans les turbines Pelton à la fin d'une période de fonctionnement précisée dans le contrat, sont à établir chaque fois que des dommages sont susceptibles de se produire dans tout ou une partie des fonctionnements envisagés.

Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests (IEC 60193:2019)
EN IEC 60193:2019

This document applies to laboratory models of any type of impulse or reaction hydraulic turbine,
storage pump or pump-turbine.
This document applies to models of prototype machines either with unit power greater than
5 MW or with reference diameter greater than 3 m. Full application of the procedures herein
prescribed is not generally justified for machines with smaller power and size. Nevertheless,
this document may be used for such machines by agreement between the purchaser and the
supplier.
In this document, the term "turbine" includes a pump-turbine operating as a turbine and the
term "pump" includes a pump-turbine operating as a pump.
This document excludes all matters of purely commercial interest, except those inextricably
bound up with the conduct of the tests.
This document is concerned with neither the structural details of the machines nor the
mechanical properties of their components, so long as these do not affect model performance
or the relationship between model and prototype performances.
This document covers the arrangements for model acceptance tests to be performed on
hydraulic turbines, storage pumps and pump-turbines to determine if the main hydraulic
performance contract guarantees (see 4.2) have been satisfied.
It contains the rules governing test conduct and prescribes 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;
– to define the extent, content and structure of the final report.
The guarantees can be given in one of the following ways:
– guarantees for prototype hydraulic performance, computed from model test results
considering scale effects;
– guarantees for model hydraulic performance.
Moreover, additional performance data (see 4.4) can be needed for the design or the operation
of the prototype of the hydraulic machine. Contrary to the requirements of Clauses 4 to 6 related
to main hydraulic performance, the information of these additional data given in Clause 7 is
considered only as recommendation or guidance to the user (see 7.1).
It is particularly recommended that model acceptance tests be performed if the expected field
conditions for acceptance tests (see IEC 60041:1991) would not allow the verification of
guarantees given for the prototype machine.
A transposition method taking into account the model and prototype wall surface roughness for
the performance conversion on pump-turbines, Francis turbines, and axial machines is
described in IEC 62097. This method requires model and prototype surface roughness data and
is takes into account the shift in nED, QED and PED factors for determining the transposition of
efficiency between model and prototype. However, in the case of Francis machines with semispiral
casing and axial machines, the transposition method has not been fully validated due to
a lack of data. In addition, IEC 62097 does not apply to storage pumps, Pelton turbines, and
Dériaz. Therefore, for these and otherwise specifically agreed upon cases where hydraulically
smooth flow conditions are assumed on the model and the prototype, the transposition formula
and procedure given in Annex D and Annex I can be applied. Applications and limitations of
both this document and IEC 62097 transposition methods are discussed in Annex E.
The method for performance conversion from model to prototype needs to be clearly defined in
the main hydraulic performance contract.

Hydraulic machines - Guide for dealing with hydro-abrasive erosion in Kaplan, Francis, and Pelton turbines (IEC 62364:2019)
EN IEC 62364:2019

This document gives guidelines for:
a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites;
b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site;
c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems;
d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings;
e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers;
f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life.
It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues.
It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation.
Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydroabrasive erosion resistant coatings can also be damaged locally by impact of large solids. It isbeyond the scope of this document  to address these issues.
This document focuses mainly on hydroelectric powerplant equipment. Certain portions can
also be applicable to other hydraulic machines.
