Chemical science and technology has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. Pay attention to fire prevention. ---------------------------------------------- Large-scale submersible oil pump units are strategically important technical equipment in the field of energy reserves in our country. China is a major oil consumer, and strategic oil reserves are related to my country's social stability and strategic security. The main function of large-scale submersible oil pumps is to pump oil stored in specific storage sites. It is a key equipment to ensure long-term, high-efficiency, safe and reliable operation of oil reserves. The independence, advancement and reliability of its technology are not only related to the safety and reliability of the reserve site, but also directly related to the implementation process of my country's energy reserve strategy. Prior to this, large submersible oil pumps were mainly monopolized by foreign companies. As the century-old changes in the world today are accelerating, and the game between major powers is becoming increasingly fierce, in order to ensure * * For strategic security and energy security, the localization of large-scale submersible oil pumps has become a major and urgent task. On February 20, 2023, the China General Machinery Industry Association organized a "Large Submersible Oil Pump Unit" product prototype appraisal meeting in Shenyang. An appraisal committee composed of 11 industry experts jointly reviewed and witnessed the development results of large-scale submersible oil pump units. Leaders from China Machinery Industry Federation, China General Machinery Industry Association, Shanghai Jiao Tong University, Northeastern University, Dalian University of Technology, Jiangsu University, PetroChina, Sinopec, CNOOC, Shengu Group and other units attended the appraisal meeting. The large-scale submersible oil pump unit product prototype that passed the appraisal this time was jointly developed by CNOOC Petrochemical Engineering Co., Ltd. and Shenyang Blower Group Nuclear Power Pump Industry Co., Ltd. This product uses a high-efficiency mixed-flow pump hydraulic model, adopts a vertical suspension pump design structure, and carries out precise analysis of multi-mode, multi-gap, and multi-media dynamics, ensuring the technological advancement, operational stability and quality reliability of the unit. At the appraisal meeting, the participating experts listened to the prototype's technical requirements and development summary report, reviewed relevant technical documents, inspected the production and testing sites, and witnessed the prototype's performance test. The performance test results of the pump unit meet the requirements of the development technical specifications, test outline and relevant standards. After comprehensive review and questioning, the expert group formed the following appraisal opinions: The large-scale submersible oil pump developed by Shengu Nuclear Power Company has a reasonable structure design, appropriate material selection, advanced manufacturing technology, and performance parameters that meet technical specifications and relevant standards. The pump unit has independent intellectual property rights, and its main performance indicators have reached the advanced level of similar international products. It is recommended to be promoted and applied.
