Description
Custom-Manufactured Hydro-Turbine Seal Head for Hydropower Plants
During unit operation, high-pressure water leaks along the clearance between main shaft and housing. The seal head serves as the main mounting housing for main-shaft sealing components. It holds sealing rings, labyrinth components and auxiliary water pipelines. It intercepts leakage flow, guides sealing cooling water, and keeps bearing chamber dry.
If the seal head has casting defects, insufficient rigidity or poor processing accuracy, it will result in large water leakage, seal-ring abnormal wear, water inflow into the oil tank, bearing emulsification and other serious faults, endangering the safe operation of turbine-generator set.
We deliver tailor-made seal-head solutions strictly based on customer drawings, main-shaft diameter, working water pressure, installation envelope and actual site working conditions.
Main Technical Features
  • High-strength cast/forged body: Optimized structure design, sufficient rigidity, resist hydraulic impact and vibration from unit operation, avoid deformation.
  • High-precision mating surface: Strictly control flatness, roundness and surface finish of seal-ring fitting position, reduce partial wear of sealing elements and extend service life.
  • Integrated internal flow passage: Pre-processed channels for sealing water and cooling water. Reasonable flow-path layout ensures stable water supply for shaft-seal operation.
  • Reasonable assembly structure: Optimized flange and bolt layout, convenient for field disassembly, replacement of wearing sealing parts and daily inspection.
  • Full-range customization service: Matching shaft diameter, pressure grade, flange standard, overall outline, internal flow-path layout and interface position can be customized for new-build, retrofit and overhaul projects. Every finished seal head passes dimensional measurement, non-destructive flaw detection and water-tightness pressure test before ex-factory.
Application Scope
  • Shaft-sealing system components supply for newly-built hydropower stations
  • Main-shaft sealing upgrading and retrofitting of existing turbine-generator sets
  • Overhaul replacement spare parts for Francis, Kaplan, bulb and pumped-storage reversible units
  • Medium-large hydropower plants, EPC contractors and power-asset operators worldwide
Our Services
  • Custom design & fabrication according to customer drawings or technical specifications
  • Structural optimization for high-water-pressure and silt-laden working conditions
  • Complete factory tests: dimension inspection, non-destructive testing, water-tightness test
  • Technical support for on-site installation, sealing commissioning and maintenance guidance
Please provide shaft dimension, working-pressure parameters or drawings, we will prepare targeted technical proposal and quotation for you.
