Kaplan & Tubular Turbine Runner

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.

Runner diameters: 0.6-3m Suitable water head: h=3-30m Capacity of the generator unit: 160-20000kw The speed range of the turbine: 60-750rpm * the propeller type is with a vertical axle and fixed runner, blade angle can not be changed during operation mode, the efficiency curve is steep and this type is generally suitable for power station that has water head with slight change or its operating units can be adjusted according to actual load change. * the kaplan type is with adjustable runner controlled by oil servomotor and moved according to the load/head change to ensure higher average efficiency, the efficiency of some kaplan turbine is higher than 94%.

Kaplan Turbine is suitable for medium & low water head and large flow power plants. With same water head, the Kaplan runner speed is higher than that of the Francis'. The Kaplan runner blade can be either fixed and rotatory. The key components include: Kaplan runner, Distributor, Main shaft, Main shaft seal, Turbine guide bearing, Governor, Draft tube, Spiral case. Tubular Turbines are suitable to lower water head, is a kind of horizontal turbine with straight flow channel. There is no spiral case in Tubular turbine, and its blades can be fixed or rotatory. The key components include: Tubular runner, Distributor, Turbine guide bearing, Governor among other.

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. Getai Hydropower is a China supplier of Francis Turbine, Francis Turbine Generator, Francis Turbine Parts, Francis Runner, Construction And Working Of Francis Turbine. 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.

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.
