给水管网中管段流量计算方法的探讨

传统方法中管段流量是根据节点流量进行流量分配,再经过复杂的平差计算后确定的。由于节点流量难以跟踪实测,只能近似估算,导致管段流量的计算精度不高,本文提出通过测压计算管段流量的方法,实例计算结果表明:该方法计算速度快,精度高,灵活性强,明显优于传统方法。

Study on the Calculations of Pipeline Flow in Water Supply Network

In tradition way, calculating pipeline flow is done by the flow distributions of joint flow and complicated calculations. Because of the difficulties in tracking and testing the joint flow, it can only be approximately estimated, this leads to the low precision in pipeline flow calculations. In this paper, a new method is put forward. The pipeline flow is calculated by measuring pressure. From the results of practical case, it is shown that the new method is fast in calculating, has high precision and strong fleaxibility. It shows obvious advantages comparing to tradition way.
