Hydraulic metal structures and construction machinery

POWERCHINA has proven technology for hydraulic metal structures and construction machinery, skilled workforce, and advance plants and equipment, such as CNC milling and flame cutting machines and powerful bore honing machines.

POWERCHINA has designed and manufactured thousands of tons of metal components and more than 3,000 pieces of equipment for water conservancy and hydropower projects, including large-size hydraulic gates, bridges, ship lifts, and cable ways. The 12 spillway gates and 24 ogee gates on permanent ship locks for the Three Gorges Project are recognized as the highest level of ship lock steel structures in China. Moreover, the hoisting winches, hydraulic hoists and gantry cranes have been recognized as “Prestigious Brand of Sichuan Province ", while the overhead travelling cranes have been used in lifting turbine-generator units in power plants, and handling materials at docks.

POWERCHINA has the intellectual property rights to the advanced technology and production of luffing, radial and parallel traveling cableways and the technologies used in and capacities of manufacturing these equipment have been the best in China. 47 cable cranes were used at the Three Gorges Project. Ship lifts made by POWERCHINA have been used by various projects, such as Yantan (250-t vertical ship lift) and Gaobazhou (300-t), etc. and have been praised as the “China’s Engine of Self-improvement”, by Pan Jiazheng, member of the Chinese Academy and Vice President of the Chinese Academy of Engineering. POWERCHINA has also developed low-, medium-, and high- pressure fully hydraulic concrete pumps, which are in wide application at different construction sites.

Power generation equipment set

1) Boiler feed water pumps

POWERCHINA-made booster pump, water feed pump, and fluid coupling are widely used in 50-1,000 MW-class subcritical, supercritical, and ultra-supercritical thermal power and nuclear power units, out of which, the 600 MW and 1000 MW-class FWP units have become the major models for development and widely used both at home and abroad due to their high efficiency, environmental friendliness, energy-saving and low-emission, and are recommended by national authorities as the first choice of auxiliary equipment for thermal power units.

2) Valves

POWERCHINA-made control valves, gate valves, cut-off valves, and check valves have seen wide use in the 1000MW-or lower-class nuclear and thermal power, metallurgical, and chemical industries. The water feed control valves, recirculation control valves and spray water control valves are widely used in the ultra (supercritical) thermal power units. The 600MW PCV valves, 600MW ultra supercritical HPH three-way valves, and 1000MW ultra supercritical main stream drain valves for the ultra supercritical thermal power units all showing outstanding performance.

Some newly innovated valves, such as the control valves for water storage tanks, water level control valves, and steam reducing valve for a soot blower, with a maximum design pressure of up to the 4,500bl - class, and a maximum operating temperature of 6100C, are used extensively in ultra-critical thermal power units. The valve products have been recommended by national authorities as the first choice of auxiliary equipment for 300-MW, 600-MW, and 1,000-MW thermal power units.

3) Fans

POWERCHINA-made centrifugal and axial fans, ball mills, and belt and screw conveyors for power plants, with the power plant centrifugal and axial fans covering more than 20 categories, with more than 110 specifications. These products hold a large market share, especially the stationary blade adjustable axial-flow fan, at 80 percent, and combined AP-ID fan, at 70 percent. POWERCHINA has customers in 29 provinces and regions across China and the world, in Russia, India, Turkey, Egypt, France, Finland, the Americas, Australia and elsewhere.

4) Coal milling

The Changchun Generating Equipment Group, a subsidiary to POWERCHINA, brought in an MPS-HP-II mill from Borsig Power Systems Gmbh from Germany to expand the applications of the old MPS mill and overcome the technical bottlenecks in the lignite plant’s coal pulverizing system. It has better performance, such as lower power and metal consumption, less maintenance, smaller space, and easy for peak regulation of power plant. Nearly 1,000 of these machines have been sold in China and more than 200 abroad.
