真空排污系统管网压力损失的估计

Prediction of Pressure Drop in Vacuum Sewer Lines

在分析多用户使用时,管网内气液多相流的流动型式的基础上,采用均相流模型建立了真空排污管网中的压力损失计算公式,为真空排污系统的开发和应用提供指导.

The airliquid flow pattern map of sewage in vacuum sewers for many users is studied. Applying singlephase flow pattern, the formula for predicting pressure drop in vacuum sewer line is derived. The obtained results will help to guide the design and development of vacuum sewers system.
