Breakthrough in Deep Space Exploration: Zhejiang University's Research on Planar Induction Electromagnetic Pump

Strategic Insights

— 1 min read

Researchers at Zhejiang University have made significant progress in deep space exploration by developing a planar induction electromagnetic pump that can provide high power density while overcoming challenges posed by space environment. The team, funded by the Natural Science Foundation of Zhejiang Province and the National Natural Science Foundation of China (NSFC), used a harmonic method combined with magnetic equivalent circuit to optimize the pump's performance. The result is a one-pole pair pump with a pole length of 66 cm and 40 mm depth, capable of pumping 16.453L/min at a pressure of 0.603 Mpa, with a power density of 31.54w/kg, a 87.4% increase compared to the original design.
