摘　　要：全面深入分析了大量物料浆体的试验与运行数据,从物料特性与浆体紊动强度两个重要因素分析浆体浓度对管道临界流速的影响,基于能量守恒提出了合理、实用的浆体管道输送临界流速公式。After the thorough analysis of the test results and operation data of slurry transportation, the effects of slurry concentration on the critical flow rate of pipeline transportation were discussed in terms of slurry properties and turbulence intensity. An equation for calculating the critical flow rate of slurry pipeline transportation proposed according to energy conservation theory has proven to be rational and practical.

关 键 词：临界流速 管道输送 粒级组成 紊动强度
