摘要
由通用计算公式推出了面粉厂负压气力输送加速段长度的数学模型,建立了面粉厂各类气力输送物料的λ_s计算方程。最后通过实验数据对加速段长度数学模型进行了验证,取得了理论值与实测值相一致的结果。
The author deduces the mathematic model of the length of accelerating stage of negative.pressure airforce conveyance in flour mills from the current calculating formula,sets up λs calculating equation of all kinds of airforce conveyance materials in flour mills. Lastly through the experimental data,the mathematic model of the length of accelerating stage is verified and the result is obtained that theory value agrees with the really determined value.
