燃料电池用双爪氢气循环泵工作特性与瞬态模拟
Working characteristics and transient simulation of double-claw hydrogen circulation pump for fuel cells
摘要
Abstract
The hydrogen circulation pump is a key component for hydrogen circulation in fuel cells,and its optimal design is very important for improving the pump performance.A new type of eccentric circular arc double-claw rotor was introduced,and its geometric model was established,deducing its profile equation.This approach aims to solve the problems of poor meshing and complex working processes of the traditional double-claw circulation pump.A smooth claw rotor was constructed using an eccentric arc and its conjugate curve,and then a claw compressor for hydrogen circulation was obtained.The working process of the new claw compressor was analyzed.Through numeri-cal simulation,the flow field variation of a new type of claw compressor was studied and then compared with the ex-isting claw compressor.The results show that the proposed new double-claw rotors can achieve full smooth mes-hing,which solves the sharp point problem of traditional double-claw rotors and enhances the gas sealing effect be-tween the rotor and the casing.Meanwhile,through the reasonable design of the discharge port,the clearance vol-ume is eliminated,and the comprehensive performance of the claw compressor is improved.These findings are greatly important for the development of claw compressors and the performance enhancement of hydrogen fuel cell systems.关键词
