Stainless Steel 50MW Vertical Francis Turbine

Stainless Steel Or Cast Steel Francis Hydro Turbine

quick detail

The Francis turbine is a reaction turbine, which means that the water changes pressure as it moves through the turbine, giving up its energy. First, high pressure water enters the turbine through the spiral casing surrounding the guide vanes. Then water passes through guide vanes where it is directed to strike the blades on the runner at optimum angles. As the water flows through the runner its pressure and angular momentum reduces. This reduction imparts reaction on the runner and power is transferred to the turbine shaft.

our advantage

The strong points of our product are water turbine generator set with capacity ranging from 1MW to 50 MW; Francis generator set with high head & rotational speed; Axial flow generator set with low head & rotational speed. We also manufacture a complete set of equipment, such as valve, governor (including PLC microcomputer governor), excitation (including PLC mirco-computer excitation), and its automation, all of which can make the generator set work in harmony. The reconstruction and alteration of the old hydropower station is also our strength. Our company boasts more than 20 years of experience and technics in this field, providing the service of technical renewal, capacity-enlargement and reconstruction.

• application range

Applicable Range Head: 20-200m Flow: 0.15-10m3/sMost widely used turbine in the world. (70-80%)Applicable head and flow range is very wide.As a type of reaction turbine, the draft tube can be used to effectively increase net head.Peak efficiency is highest among all turbine types. (85-94%)Due to its complex design and large number of moving parts, maintenance and repair can be significant.

DEC Dongfeng Electric Machinery Co., Ltd(hereinafter referred as to Dongfeng)formerly known as Sichuan Dongfeng Motor Works, was founded in 1965. As a top-secret military enterprise during the “Third-front Movement”, Dongfeng made a significant contribution to national defense development. In the late 1980s, Dongfeng was gradually transformed from a military company to a civil one, and in 2001, it was reformed to a LLC , wholly-owned subsidiary of Dongfang Electric Corporation and developed into a leading manufacturing enterprise of power generating equipment and electric motor in China. In 2018, Dongfeng was further restructured to a state-owned holding enterprise with the major shareholders of COQ Asset Management Co., Ltd. (a subsidiary of China Orient Asset Management Co., Ltd.), DEC and its top management.

Dongfeng was awarded abundant honorable titles, such as China's Top 500 Manufacturing Enterprise, National High-tech Enterprise, Customer Satisfied Enterprise of National Machinery Industry, Customer Satisfied Enterprise of National Product Quality & After-sales Service, China's Credible Enterprise, National Grade-one Metrology and Grade-one Safety Standardization. Dongfeng was also certified with ISO9001 quality management system, GJB Weapon Equipment Quality Management System, IATF16949 Automobile Quality Management System and HSE National Occupational Health and Safety ( Environment Management ) System, and has implemented the information system of ERP/OA/E-HR/SRM/CAPP and so on.

Dongfeng has a powerful strength of research and development , and it is one of the auxiliary research units of the national "863" program as well as the research center of high-efficiency electrical engineering technology in Sichuan province. There is a specialized R&D team in which top experts are granted allowance from the state council and senior engineers are included. Dongfeng is able to realize R&D of all series products by using sophisticated design tools such as the large-scale CAD workstation and the CATIA 3D software. The national level double-fed wind power generator test station, and the electric drive system test center can meet product quality assurance by conducting series of tests and verifications.

Dongfeng is capable of designing and manufacturing the Francis type, Kaplan type, Tubular type, Impact and Pumped Storage Hydro Generator Set with unit capacity up to 150 MW, and conventional steam turbine, TRT, gas turbine, cogeneration steam turbine generator set of unit capacity up to 60 MW , and wind turbine generator set of unit capacity from 1 MW to 3 MW, and new energy electric vehicle drive system, high-efficient motor, special motor, medium frequency motor, large and medium pump equipment, environmental protection equipment, large hydraulic metal structural parts and so on.

Dongfeng is empowered to import and export mechanical and electrical products by itself. And Dongfeng products have been successfully exported to more than 30 countries and regions including the United States, Japan, Chile, Turkey, North Korea, India, Pakistan, Vietnam, Myanmar, Ethiopia and so on. More than 1,200 sets of hydroturbine generator, 1,800 sets of steam turbine generator, 5,000 sets of wind turbine generator and up to 10,000 sets of drive system are provided to customers home and abroad. With its energy efficiency level superior to the national standard level-1, the ultra-high efficient permanent magnet synchronous motor of Dongfeng has been certified by CQC China energy-saving product and listed into the promotion catalogue of "energy efficiency star" issued by Ministry of Industry and Information Technology in 2017.

Dongfeng is situated in Leshan City, Sichuan Province, a famous historical and cultural city, adjacent to two World Cultural and Natural Heritage Emei Mountain and Leshan Giant Buddha. Near the mountain and by the river, Dongfeng has its own factory covering area of more than 700 acres and is blessed with its advantage of convenient transportation.

Dongfeng is always tirelessly adhering to the company philosophy of “discovering value and creating the future” and repay to the society with products and service of high quality. Looking forward to the close cooperation with customers home and abroad for mutual development.
