The hottest KSB helps Yan'an Yellow River Diversio

KSB helps Yan'an Yellow River Diversion Project and escorts the lifeline of water supply. Yan'an, an ancient and magical land, is China's red "revolutionary Holy Land". The Yellow River, known as China's "Mother River", flows along Yan'an. However, Yan'an is seriously short of water. "Guarding the Yellow River without water to drink" is a true portrayal of Yan'an City for a long time. KSB helps Yan'an Yellow River Diversion Project, which is the lifeline of water supply.

the ancestors of the Chinese nation created the world by following the water and left legends in Yan'an for thousands of years: the Fuxi footprints of the Qiankun Bay of the Yellow River, the drainage waterfall of the great Yu at hukou to control the water, the immortal historical stories of the Yellow Emperor tribe along the JuShui River to create Chinese civilization, the Yellow River, Yanhe River, Luohe River, JuShui - Landscape Yan'an, a happy home

however, Yan'an is also a city with serious water shortage. The carrying capacity of water resources is insufficient and the spatial and temporal distribution is uneven. The total amount of water resources is 1.335 billion cubic meters, and the per capita share is only 612 cubic meters. Due to the transfer of diesel in Europe and the penetration of electric vehicles, it is only 8.1% of the world average level and 29% of the Chinese average level

with the development of urbanization, the urban scale of Yan'an has expanded, the population has increased, and the economy has accelerated. The contradiction between water supply and demand has become increasingly prominent. It is reported that Yan'an consumes about 80000 tons of water a day, and there is a water supply gap of nearly 30000 tons every day. The shortage of water resources has become one of the important factors affecting the economic and social development of Yan'an

after careful investigation and calculation, it is shown that water diversion from the Yellow River is the best way to fundamentally solve the shortage of water resources in Yan'an urban area and the northern region

in October 2014, Yan'an's "lifeline" project, the Yan'an Yellow River Diversion Project, officially started construction, with a total investment of 4.385 billion yuan. Finally, water supply was officially provided in the second half of 2018, increasing the water supply of Yan'an's new and old urban areas by more than 60000 tons per day. This great project not only breaks the "bottleneck" restriction of water resources in Yan'an, helps support the strategic basis of "water diversion and industrial transformation" determined by the fourth municipal Party Congress, but also has a huge positive impact on the long-term economic and social development of Yan'an

the total length of the water transmission pipeline of the project is 145.78 kilometers, the annual water intake is 89.77 million cubic meters, and the design includes 9 pump stations, 2 reservoirs, 2 water plants, 1 sediment treatment station, and 9 tunnels. In the whole project, the sediment treatment of Yanshuiguan water intake project is the top priority of the Yellow River Diversion Project. It undertakes the main tasks of water intake, sediment separation and water clarification of the whole line. It is one of the most critical treatment process units, and is of great significance to the operation of Yan'an Yellow River Diversion Project. After more than three years of construction, this pivotal project has been successfully completed, and the maximum daily water intake will reach 362900 cubic meters, ensuring that the people of Yan'an can drink pure yellow river water

ksb has made indelible contributions to the smooth water supply of the whole project. The water quality of the Yellow River has high sediment content, which requires extremely high requirements for pump castings and manufacturing technology, and the maximum requirement for lift is 150 meters. Including the second stage pump station of Yanshuiguan, the top priority of the Yellow River Diversion Project, KSB also includes the third stage pump station of Baishu Di and the fourth stage pump station of gaojiawan (big station), a total of 3 big stations, providing 24 double suction single-stage horizontal centrifugal pumps with different coordinates, and supporting Y-series high-voltage asynchronous motors (the maximum power of a single unit is 1800kW, the minimum power is 355KW, and the installed power reduces the energy consumption of 100million tons of standard coal by 24235kw)

in the year of serving Yan'an people, KSB solution operated stably, with low noise, energy saving and high efficiency. It escorted the Yan'an Yellow River Diversion Project, and solved the production and domestic water supply problem of Yan'an along the Yellow River, one district, four counties, six industrial parks and 1million people along the line (Note: Yan'an's total population is 2.18 million)

in the future, KSB will, as always, deeply cultivate the market, actively explore the market with innovative, green and efficient water technology solutions, comprehensively help various people's livelihood engineering systems, make contributions to better planning, allocation and management of water resources, and work with the broad masses of people to build green waters and mountains and jointly build a beautiful home
