BS EN 60609-1 is a technical specification as a part of IEC 60609 series that serves as a basis for the formulation of guarantees applied to cavitation pitting for reaction hydraulic turbines, storage pumps, and pump turbines. BS EN 60609-1 addresses the measurement and evaluation of the amount of cavitation pitting on certain specified machine components for given conditions, which are defined in the contract by output, specific hydraulic energy (E), speed, material, operation, etc.
The cavitation-pitting evaluation is based on the loss of material during a given time and under accurately defined operating conditions. All wetted surfaces are considered. The contract documents shall state whether cavitation pitting on the hydraulic machine should or should not be anticipated in all or in some operating ranges. Guarantees that restrict the extent of cavitation pitting are necessary for the contract whether cavitation pitting is anticipated or not.
BS EN 60609-1 on cavitation pitting evaluation is useful for:
Hydro turbines are devices that transfer energy from moving water to a rotating shaft to create electricity in hydroelectric power facilities. When water is supplied to the blades of these turbines, they rotate or spin. Turbine pumps are utilised in clean liquid applications that need a high head, low flow, compact construction, and adaptability.
BS EN 60609-1 addresses the terms, definitions, nature, and extent of cavitation pitting guarantee along with the procedures for repair and measurement. Using BS EN 60609-1 guidelines provides the users with high quality, durability, safety, and protection to the users.
