The official website of Shanghai Songjiang Group will introduce to you: [Guizhou China Hydropower Station] oil-resistant ANSI Flanged Rubber Bellow contract information,Shanghai Songjiang Group has provided various high-quality ANSI Flanged Rubber Bellow products for many hydropower station projects. Following is detailed introduction.

1. Introduction of Guizhou Guangguang Hydropower Station:
Guizhou Hydropower Station is located in the middle reaches of Beipanjiang River at the junction of Guanling and Jinglong counties in Guizhou Province. It is more than 600 meters above sea level. It is high in the northwest and low in the southeast. The plateau monsoon climate has a frost-free period of 356 days throughout the year. As the “leading head” of Beipanjiang Station, it is mainly for power generation, taking into account shipping, irrigation, water supply and other water conservancy projects. The area of ​​the watershed above the dam site is 13,548 square kilometers, the average annual flow is 257 cubic meters per second, the normal water level is 745 m, the backwater length of the reservoir is 69 km, the reservoir area is 51.54 square kilometers, the total storage capacity is 3.245 billion cubic meters, and the corresponding storage capacity of the normal water level is 31.35 100 million cubic meters, and the regulating storage capacity is 2.037 billion cubic meters, which is an incomplete regulating reservoir. The installed capacity of the power station is 1040MW, and the average annual power generation is 2.754 billion kw.h.
Guangguang Hydropower Station is located in the middle reaches of Beipan River in Guizhou. It is a large-scale hydropower project in the second batch of “Four Waters and Six Fires” power point construction projects of “West-East Power Transmission” in Guizhou. The power station has an installed capacity of 1,040 MW and a dam height of 200.5 meters. It is the world’s tallest dam among roller compacted concrete (RCC) gravity dams that have been built. The 200-meter-level world high dam was built in less than three years from the start of construction to the completion, which rewrote the RCC dam construction record in terms of speed and quality, and created the advanced level of domestic dam construction.
On October 25, 2012, at the 6th International RCC Dam Conference held in Spain, the Guizhou Guangguang Hydropower Station constructed by the 16th, 4th and 7th Bureau of China Hydropower Bureau was awarded the International RCC Milestone Award. This is also the only award our country has won at this conference.
Guangguang Hydropower Station is located at the junction of Qinglong County and Guanling County in Guizhou Province. It is the leading hydropower station for cascade hydropower development below Maokou, the main stream of Beipan River. It is one of the few hydropower stations in Guizhou Province with incomplete multi-year regulation performance. Large hydroelectric power point. Design and installation of 4 Francis turbine generator units with a single unit capacity of 260,000 kilowatts, with a total installed capacity of 1.04 million kilowatts and an average annual power generation of 2.754 billion kilowatt-hours. The total investment is 6.903 billion yuan. The power station is mainly responsible for peak regulation, frequency regulation, accident and load backup in China Southern Power Grid. At the same time, it can improve the water energy regulation capacity of the main stream of Beipan River and increase the power generation efficiency of downstream cascade power stations. The construction of the power station is of great significance for implementing the national development strategy of the western region and the power transmission from west to east, accelerating the development of clean energy and renewable energy strategy, turning resource advantages into economic advantages, and promoting the economic and social development of ethnic areas. After the power station is completed, it is mainly responsible for peak regulation, frequency regulation, accident and load backup in the power system. At the same time, it can greatly improve the water energy regulation capacity of the main stream of Beipan River and increase the power generation efficiency of downstream cascade power stations.
The Guangguang Hydropower Station project was in the preliminary survey stage in 1983; it entered the initial design stage in 1989; it entered the formal design from 1995 to 1996; in 2000, the Guangguang Hydropower Station construction project was officially listed as a key construction project of the country’s “West-to-East Power Transmission”. The preliminary construction preparations started in May 2003, the river was closed in October 2004, and the sluice gate was closed on December 30, 2007 for water storage. Through the research on roller compacted concrete dam building technology, the normal concrete gravity dam was successfully transformed into a roller compacted concrete gravity dam, and a world-class roller compacted concrete gravity dam with a height of 200.5m was built.
Guangguang Hydropower Station is the tenth cascade power station of the main stream of Beipan River. It is located in the middle reaches of Beipan River, about 600m upstream of Guangzhao Xiaohekou, within the two counties of Guanling and Qinglong in Guizhou Province, with a controlled drainage area of ​​13,584 square kilometers. The geographic location is 105°15’00” east longitude and 25°37’34” north latitude. The valley of the dam site is a basically symmetrical V-shaped canyon. The natural slope of the bank slope is 40°~50°. The bedrock on both sides is exposed, the overburden is scattered, and the overburden of the river bed is 4~26.8m thick.
The Guangguang Hydropower Station is a multi-year regulating performance hydropower project that focuses on power generation, combines shipping, and takes into account irrigation, water supply and other comprehensive benefits. Through the regulation of runoff by the power station, the flow of the lower reaches of the Beipan River can be greatly increased during the dry season, and the navigation conditions of the lower reaches can be improved. The characteristic parameters of the hydropower station are shown in the table.
As of September 20, 2012, the Guangguang Hydropower Station has been in safe operation for 1,509 days, generating a total of 8.85 billion kWh since it was put into operation. benefits and social benefits. The construction of Guangzhao Hydropower Station not only creates direct economic benefits of 2.541 billion yuan, but also pays more than 80 million yuan in taxes every year, which plays a pivotal role in the overall improvement of local economic and social development capabilities.

3. [Guizhou Guangguang Hydropower Station] Introduction of oil-resistant ANSI Flanged Rubber Bellows:

The oil-resistant ANSI Flanged Rubber Bellows for hydraulic oil pipeline systems are mainly synthesized from various elements such as nitrile rubber, butyl rubber and natural rubber. The oil resistance of the glue has been greatly improved and improved. At the same time, the life and quality of soft joints used in hydraulic oil, petroleum, engine oil, diesel oil, lubricating oil and other environments have been improved. It avoids the trouble of frequent cracking, corrosion and frequent replacement of the soft joints used in the oil state, and also wins the satisfaction and recognition of the majority of users.
