中文摘要:

      螺旋泵可用来输送高粘性液体，该过程中由于液体的温度升高而粘度降低，因而其粘性耗散不能忽略。本文介绍一种上述情况下计算液体粘度、泵的功率和压力降的近似公式。

英文摘要:

      Screw pumps can be used to highly viscous liquid. Viscous dissipation cannot be neglected during such pumping because it causes the temperature of liquid to rise and its viscosity to decrease. An approminate method is introduced for calculating the viscosity, the power of the pump and pressure drop under these conditions.
