Against the backdrop of the accelerated upgrading of the global energy industry, exciting news came from my country’s power equipment manufacturing industry. The first batch of 2*300MW boiler feed pumps for power plants exported by Kaiquan Pump Industry Group successfully passed the acceptance inspection, achieving a major breakthrough in the export of domestic power equipment. This achievement not only demonstrates the outstanding technical strength of Kaiquan Pump Industry Group in the field of high-end power equipment manufacturing, but also highlights the strong competitiveness of “Made in China” in the international market.
Overcoming difficulties and achieving a comprehensive technological leap
In May 2022, the Overseas Business Department of Kaiquan Pump Industry Group undertook an overseas customer’s BB5 pump upgrade and transformation project for a 2*300MW power plant boiler feed pump.
Faced with this important task, Kaiquan Pump Industry Group quickly organized a design and technical team to conduct in-depth field investigations. Fully connect with the design institute on product standards, dimensions, materials, performance and other detailed requirements. , and conduct differentiated analysis on the system requirements of power plants, while fully digesting the differences between national standards and international local standards. In order to meet the owner’s strict technical and delivery standards, we will fully promote technology research and development.
After several months of hard work, in October 2022, the technical plan was submitted to the owner for review. Since then, it has been more than a year of investigation and demonstration. Until 2024, Kaiquan Pump Industry Group’s technology and supply plan were finally recognized by the owner and the design institute.
The 2*300MW boiler feed pump for the power plant is the core equipment of the thermal power generation system. Its performance plays a decisive role in the safe and stable operation of the power plant and the energy conversion efficiency.
In order to overcome technical difficulties, the technical center of Kaiquan Pump Industry Group and the technical team of the branch plant have formed a top R&D team that brings together experts in fluid mechanics, mechanical design, materials science and other fields.
Focusing on the core goals of improving the efficiency of pump units, reducing energy consumption, and enhancing reliability, arduous special technical research has been carried out.
In response to the key problem of efficiency attenuation of traditional pump units under high head and large flow conditions, the R&D team boldly innovated and adopted a new hydraulic model design. Through the use of CFD (computational fluid dynamics) simulation analysis and optimization, the overall efficiency of the pump unit has increased by nearly 8%, reaching the international leading level. This technological breakthrough not only greatly reduced the operating costs of power plants, but also actively implemented the green development concept of Kaiquan Pump Industry Group.
Strict testing, excellent quality demonstrates strength
Quality is the lifeline of the product, and it is also the core competitiveness of Kaiquan Pump Group’s brand in the international market. The 2*300MW boiler feed pump for power plants exported this time strictly follows international standards and customer special requirements during the production and testing acceptance process, and has undergone a series of nearly rigorous tests and inspections.
In the performance test, the pump unit has been running stably for more than 168 hours, and all performance indicators have reached or even exceeded the design requirements. The stability of its head and flow rate and its efficiency performance have won unanimous praise from Chinese and foreign experts.
In the vibration test, even at full load, the vibration value of the pump unit is far lower than the international standard limit, which fully confirms the scientific nature of its structural design and the exquisiteness of its manufacturing process.
It is worth mentioning that Chairman Lin Kaiwen personally attended the product testing and acceptance meeting and witnessed this important moment.
Finally, this batch of boiler feed pumps manufactured by Kaiquan Pump Industry Group passed the acceptance inspection with zero defects under multiple rigorous tests of ISO international standards, Russian GOST certification system and customer-specific acceptance standards, fully demonstrating the excellent quality and reliability of “Made in China” to the global market.
