Since the station away from the city's place in the most generator prices, it usually takes a long transmission line to the load, and therefore, the stability of the power system to run the proposed hydroelectric generating higher requirements: motor parameters requires careful selection; moment of inertia of the rotor requires a larger. So the generator set suppliers, appearance and hydro turbine generator is different from its rotor diameter and shorter length. Hydroelectric generating set start and net takes less time to run generators flexible scheduling, in addition to its general power, particularly suitable for use as a peaking unit and emergency reserve unit. The maximum capacity of the hydroelectric generating set has reached 700,000 kilowatts. Weifang Huadong Engine Co., Ltd. is located in the "Power City of China" reputation of Weifang generators vendors, is a diesel engine, generator sets, mobile power plants, silent generator, gas generator, water pump R & D, manufacturing and sales an integrated enterprise. The company has a strong R & D capability and manufacturing. When more than 6 times the diameter of the body length, the second critical speed of the rotor will be close to the motor running speed, running a large vibration may occur. Therefore, the size of large high-speed turbo-generator rotor severely restricted. About 100,000 kilowatts of its rotor size of air-cooled motor has reached the limits of the size of the above, again increasing the motor capacity only by increasing the electromagnetic motor load to achieve. So we must strengthen the motor cooling. So 5 to 10 million kw turbine generator have adopted the cooling effect of a good hydrogen-cooled or water-cooled technology. Shandong generators, Weifang Huadong (certified), generators provided by Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) is an industry leader in Shandong Weifang, the internal combustion engine, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Weifang Huadong leadership with the staff warmly welcome all inquiries negotiations to create a better future Weifang Huadong.
