在传统涡轮流量计叶轮力矩平衡的理论基础上 ,运用机翼理论和叶栅理论建立双涡轮流量计流动理论模型 ,并对双涡轮流量计的质量流量进行理论推导 ,实验表明理论推导结果与实测值基本吻合
Based on the theory of impeller moment balance of traditional turbine flowmeter, the theoretical model of flow field of twin-turbine flowmeter is established by using wing theory and cascade theory, and theoretical derivation of mass flow rate of double-turbine flowmeter is carried out. The value is basically consistent
