Francis Turbine Suppliers and Manufacturers

In a Francis turbine, the water flows radially into the turbine and axially out of the runner. The Francis turbine, invented by an American engineer in 1849, is the most widely deployed modern turbine. The main characteristics of the Francis turbine are - a wide range of water head, simple and reliable structure, and high efficiency. A Francis Turbine can be supplied for a head of 15 m to 250 m. The runner diameter is available from 0.4 m to 4.5 m. Power capacity is from 75 kW to 50 MW. New style francis turbine, compared to the old one, it has the advantages of convenient installation, high efficiency, low noise and compact structure.

Forged Entire CNC Machined Francis Runner Forging could considerably improve metals 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.

We have a complete quality management system. Choose us, you can be get most careful and thoughtful service! 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.

All Pelton runners are made of stainless steel usually obtained from a casting of a single piece. This extends the life of the runner because it improves the fatigue and corrosion resistances. These turbines can be designed both with vertical or horizontal shaft and equipped with one to five injectors. All wear parts are made of stainless steel and are easy to replace. For drinking-water distribution lines applications our turbines can be manufactured completely in stainless steel and all polluting materials are strictly avoided, including lubricating oils and greases.

The Axial turbine is for low head power plants. Water flows axially into and out of the turbine. Axial flow turbines fall into two categories, fixed blade runner and variable pitch runner, also known as a Kaplan turbine. Fixed blade turbines are very well suited to low head power plants with limited variation in head and load. Its main advantage is its simple design. When operated at fixed speed, maximum efficiency is achieved at the design head and water flow. Kaplan turbines are used for medium to large power stations where there are large variations in the head, water flow and load. Its main advantage is its ability to adapt to variable conditions with a high efficiency. The variable pitch runner is mechanically more complex than a fixed pitch runner. Axial flow turbines can be supplied for a head of 2m to 70 m. The runner diameter is available from 0.6 m to 5 m. Power capacity is from 55 kW to 50 MW.

The tubular turbine is an axial flow turbine, in a straight or S-shaped configuration. A Tubular Turbine can be supplied for a head of 2 m to 30 m. The runner diameter is available from 0.8 m to 5.6 m. Power capacity is from 250 kW to 15 MW. This turbine has high efficiency and lower constructon cost.

Pelton turbine The runner has bucket shaped blades on the periphery. The jet of water is tangential to the runner. The characteristics are, high head applications, a simple design, few problems with cavitation, highly cost effective. Pelton turbines can be supplied for a head of 100m to 500 m. The runner diameter is available from 0.55 m to 1.5 m. Power capacity is from 200 kW to 10 MW. Inclined jet turbine: The water flows into and out of the runner at an angle to the main shaft. The characteristics are high efficiency over a wide range of water flow, more flexible installation options, somewhat more complex than a Pelton turbine. Inclined jet turbines can be supplied for a head of 60m to 300 m. The runner diameter is available from 0.32 m to 0.8 m. Power capacity is from 55 kW to 6.3 MW.

Pelton Turbine Generator Pelton turbine is suitable for medium and high water head power plants. The key components are: Pelton runner, main shaft and Nozzle assembly. Application Scope: Alcance de aplicaci�³n: Water Head:�  100 ~ 1700m Output:�  0.1� ~ 300MW Frequency:�  50/60HZ Runner Diameter:�  0.5 ~ 3m Lift Span 30-50 years 1.Advanced CFD, FEA technic is utilized in the designing process to ensure better technical solution. 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 Shenyang Getai Hydropower Equipment Co.,Ltd main products: Pelton Turbine, Francis Turbine, Kaplan Turbine, Tubular Turbine, Pelton Turbine Generator, Francis Turbine Generator, Double Francis Turbine, Pelton Turbine Formula, welcome to our factory!
