China Dongfang Electric shielded pump enters the coal-to-liquids industry for the first time
Recently, Dongfang Electric successfully won the bid for the 100,000 tons/year coal hydrogenation and upgrading unit high-pressure shielded pump project. Dongfang Electric's shielded pump entered the coal-to-oil industry for the first time.
The development of the coal-to-oil industry is a major measure to further promote the energy revolution. It is of great significance to ensure my country's energy security, improve the voice of international oil trade, and realize the clean and efficient transformation and utilization of coal. The shielded pump of this project is the key core equipment of the coal-to-oil production line. The main conveying medium is oil-coal slurry, with a design temperature of 450℃ and a design pressure of 20Mpa, which has extremely high requirements for the pump.
The canned motor pump is a non-rotating static seal pump. It adopts the integrated structure design of "water pump + motor". The water pump part and the drive motor are connected as a whole. The medium to be transported is sealed in the pump and the motor. Compared with traditional mechanical sealing equipment, it truly achieves "zero leakage". The canned motor is suitable for high temperature and high pressure, flammable and explosive, toxic and harmful environments. It has the advantages of "zero leakage, long life, high reliability", etc. It has a wide range of applications, complex development technology, and great difficulty in research and development.
Key core technologies cannot be obtained, bought, or begged. In recent years, Dongfang Electric has successively broken the technology monopoly of developed countries in the field of canned pumps and established a complete system of canned pump industry. Chemical canned pumps and canned boiler water circulation pumps have blossomed together, and products are exported to the European market.
Looking to the future, Dongfang Electric will adhere to the innovation-driven development strategy, strengthen basic and cutting-edge technology research, continue to carry out original and subversive scientific and technological innovation, achieve a higher level of scientific and technological self-reliance in the field of canned pumps, and make new and greater contributions to national defense security and high-quality economic and social development!
