GOST 27807-88 PDF

Full title and description

GOST 27807-88 — Vertical hydraulic turbines. Technical requirements and rules of acceptance. Specifies technical requirements, inspection and acceptance procedures for vertical hydraulic reaction turbines (adjustable-blade axial and radial-axial types) intended to drive hydro-generators.

Abstract

This standard establishes mandatory technical requirements and acceptance rules for vertical hydraulic reaction turbines of two systems (adjustable-pitch axial — Kaplan-type — and radial-axial) referenced to the dimensional and hydraulic parameters of GOST 27528-87. It covers criteria for design-related characteristics, factory testing, documentation and acceptance procedures required before turbines are delivered for installation on hydroelectric generator units.

Scope

Applies to vertical hydraulic reaction turbines of two systems — adjustable-pitch axial (pivot-blade, commonly Kaplan-type) and radial-axial — manufactured for driving hydro-generators. The standard sets out the essential technical requirements, acceptance testing and documentation that manufacturers and buyers must follow for factory acceptance and delivery of turbine units.

Key topics and requirements

• Definitions and classification of vertical reaction turbines covered (axial adjustable-blade and radial-axial systems).
• Technical requirements for hydraulic, mechanical and dimensional characteristics referenced to GOST 27528-87.
• Factory acceptance procedures, including required tests and test-run conditions (performance, vibration, clearances, balancing and sealing checks).
• Quality assurance and documentation to accompany delivered turbines (test reports, material certificates, dimensional checks).
• Acceptance criteria and permissible deviations for key parameters (efficiency, rotational speed, allowable vibration and leakage limits).
• Responsibilities of manufacturer and purchaser during inspection and acceptance operations.

Typical use and users

Used by turbine manufacturers, design offices and engineering contractors, hydroelectric plant owners and maintenance teams, factory and independent testing laboratories, procurement and quality assurance departments, and national/regional conformity bodies involved in commissioning hydro-generator units.
