Forged Entire CNC Machined Francis Runner
Forging could considerably improve metal organizational structure and mechanical property.  
Forging offers uniformity of composition and structure. Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product particularly in terms of impact and shear strength.
Forged steel is generally stronger and more reliable than castings of same material due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.

Forged Integrally +100% CNC Machining Francis Turbine Runner
1. GETAI has improved the manufacturing procedure of Francis turbine runner which suffered from the problems such as the cavitation and abrasion, welding seam cracks between crown, band and vanes, block worn off from vane etc. The whole Francis runner is forged integrally followed by entire CNC machining to eliminate tiny blowholes and slag inclusions existed on passage surface which accelerate cavitation and abrasion, and solve the potential risk existed by unreleased stress left after welding. The Francis turbine runner service life prolonged consequently.
In the case the high head Francis runner with long and narrow passageway which is hard for entire CNC machining or the runner size exceeds the forging range which can not be forged integrally, GETAI applied a procedure by dividing the runner to two parts which consisted of crown with half vanes and band with rest half, both two parts can be forged integrally with entire CNC machining and welding assembled in final. The welding applied to the middle of vane, where is convenient for single pass welding without touch of potential crack area, the operation security and service life are improved largely.
Samples exhibited below is for forged integrally+100% CNC machined Francis turbine runner (half part) which finished by our five axis linkage CNC machine.

This project is located in a national park in Kinshasa, the capital city of Democratic Republic of the Congo. It is an international electromechanical & hydropower general contracting project of Getai Hydropower as a hydropower equipment supplier. The scope of equipment supply includes: hydro-turbine, generator, excitation device, governor, water supply and drainage system, automatic control system, high and low-voltage systems, etc. Getai Hydropower chooses the supervision system to strictly control the product quality, other than hydraulic turbine, provided by its subcontractors to ensure the overall product quality. The advanced optimization design method is adopted in the hydraulic and structural designs of the turbine units. The core component of the turbine, namely: the runner is designed by CFD Analysis, which improves the specific speed of the turbine, reduces the dimensions of turbine units, improves their speed, and realizes the direct connection between turbine and generator. Therefore, that solves the difficulty of how to install the low water head Kaplan turbine units without speed increaser, simplifies the structural design of the units, improves the reliability and stability of the unit operation, and reduces the period and costs for unit maintenance.
Our company works as the general contractor for electromechanical equipment. We are responsible to provide the hydro-turbine and generator products, including: Kaplan turbine runners, distributors, shafts, elbow pipes, bearings, inlet pipes, runner chambers, etc. for turbine, and rotor, stator, governors, excitation devices and relevant accessories for generators.

Getai Hydropower is one of the leading Pelton Turbine manufacturers. Our Pelton Turbine Generator, Pelton Turbine Efficiency, Pelton Runner has high quality and competitive price, and you can see the Application Of Pelton Turbine.
CFD analysis for Pelton turbine is performed in order to predict the turbine performance. The head loss in the collecting pipe and injector assembly is calculated based on CFD analysis results.
The relation of needle stroke and flow also can be calculated. CFD� analysis can improve injector� and nozzle design to reduce head los. The flow curve relative to needle stroke can be drawn based on analytical data.
CFD analysis can simulate the whole procedure which flow coming into and outgoing from bucket. The flow visualization can clearly show whether water flow outgoing from bucket pressure side hit the bucket back side. Such flow situation will cause more hydraulic loss and should be avoid during runner bucket optimum design process. The torque generated by runner and pressure distribution in the bucket can be calculated based on CFD analysis results. Turbine output and efficiency is finally predicted for various operating points
The possible location of cavitation can be predicted based on the pressure distribution in the bucket. The phenomena of cavitation should be avoided in the back tip of splitter by optimum design for back shape of splitter
