Datang Group Corporation purchases a batch of split-case centrifugal pumps

Datang Group Corporation was officially established on December 29, 2002. It is a state-owned, super-large energy enterprise directly managed by the central government, with a registered capital of 37 billion yuan. Its business is extensive, covering electricity, coal and coal chemical industry, finance, environmental protection, trade and logistics, and emerging industries. It owns 5 listed companies and 45 regional and professional companies. The company actively implements the new national energy security strategy, fulfills its economic, political, and social responsibilities as a central energy enterprise, upholds the mission of "providing green energy and illuminating a better life," and strives to build a "green and low-carbon, multi-energy complementary, efficient and collaborative, and digital and intelligent" energy supplier. With the values of "pragmatism and innovation, co-creation and sharing," and the spirit of "unity and strength, pursuit of excellence," it continues to move forward. By the end of 2024, its installed power generation capacity exceeded 200 million kilowatts, the proportion of clean energy continued to increase, total assets exceeded 860 billion yuan, and operating and under-construction assets were distributed in 31 provinces (autonomous regions, municipalities directly under the Central Government), the Hong Kong Special Administrative Region, and several countries and regions including Myanmar and Cambodia. It has been selected for the World 500 for 15 consecutive times. It undertakes more than half of the power supply for the capital and the heating of nearly 930 million square meters in the "Three North" region.

Split-case centrifugal pump

Split-case centrifugal pump Convenient maintenance, no pipeline dismantling required; double-suction impeller design, large flow rate and stable operation; simple pipeline installation, and flexible adaptability to different sites and medium transportation requirements. As a powerful equipment for fluid transportation, the split-case centrifugal pump stands out in the fierce market competition with its many advantages.

High efficiency and stable operation: The impeller mostly adopts a double-suction structure, making the forces on both sides of the pump body balanced, effectively reducing vibration and noise during operation, and ensuring the long-term stable operation of the equipment. The double-suction structure increases the flow area of the liquid, significantly improving the flow rate. Under the same speed and impeller outer diameter, the flow rate is significantly increased compared with the single-suction pump. In addition, the symmetrical design of the impeller basically balances the axial force, reducing the load on the bearings, extending the service life of bearings and other wearing parts, reducing the overall maintenance cost of the equipment, and maintaining the long-term efficient operation of the equipment.

Strong adaptability in installation and use: The inlet and outlet of the split-case centrifugal pump are in the same direction and perpendicular to the pump shaft, which facilitates pipeline layout and installation, and can flexibly adapt to the needs of different sites and processes. In large water supply and drainage and mine drainage projects, it can adjust the output according to the actual operating conditions with its excellent flow regulation capability, meeting the needs of different production stages. Moreover, this pump is applicable to a wide range of media, whether it is clear water, sewage, or liquids with certain corrosiveness and particulate impurities, it can be transported stably.

Outstanding advantages in maintenance and maintenance: The pump body of the split-case centrifugal pump is horizontally split along the axial center line. During maintenance, only the upper cover of the pump body needs to be opened, and the motor and pipeline do not need to be disassembled, so that the internal key components such as the impeller and shaft can be quickly accessed, greatly shortening the maintenance time and reducing labor intensity. At the same time, this design facilitates the cleaning, inspection, and replacement of parts by personnel, timely detection of potential faults, reducing equipment downtime, and improving equipment utilization. Taking chemical enterprises as an example, the convenience of split-case centrifugal pumps during daily maintenance and emergency repairs can help to quickly resume production and reduce the impact of maintenance on production.
