The joint development team led by Yang Fengyu, a professor at the Energy Institute of Lanzhou University of Technology, successfully developed the first composite basalt fiber spacer magnetic pump in China, which increased the efficiency of the original metal spacer magnetic pump unit by 9%.
The joint R & D team was composed of Lanzhou University of Technology and DLSF Pump Co., Ltd., ZZDD Basalt Fiber Technology Co., Ltd., and XY Denko Co., Ltd. provided experimental support.
Basalt fiber is a continuous fiber made of basalt material melted at 1450 ℃ ～ 1500 ℃ and drawn by platinum rhodium alloy wire drawing plate at high speed. Its strength is equivalent to high-strength S glass fiber. It has many excellent properties such as environmental protection, no pollution, electrical insulation, corrosion resistance, and high temperature resistance. It is one of the four major fiber materials developed in China.
Professor Yang Fengyu introduced that the successfully developed composite basalt fiber spacer magnetic pump will have broad application prospects in the military, petroleum, chemical, metallurgy and other military industries.
It is understood that Professor Yang Fengyu retired from the school in 2011. For many years, he has continued to work hard in the fields of fluid control and magnetic physics and magnetic technology. A few days ago, he was invited by the China Nuclear Power Research and Design Institute and the China Nuclear Nuclear Reactor Thermo-Hydraulic Technology Key Laboratory to give an academic lecture on "Development and Related Technologies of Lead-bismuth Alloy Pumps for Lead-bismuth Reactors."
He pointed out that if nuclear waste is not disposed of safely, it will always pose a potential radioactive threat to human beings. The accelerator-driven subcritical system using lead-bismuth alloy as a coolant is an ideal nuclear waste transmutation treatment device, which can convert long-life high-radioactive nuclear waste into low-toxic short-lived nuclides or stable nuclides to reduce the potential risk of radioactivity . Relevant research results can be applied to various advanced nuclear energy systems at the same time, with broad application prospects.
