低压配气环网调峰压力的计算

calculation on peak pressure of low pressure distribution loop network

介绍了一种简便的环状管网调峰压力计算方法。用支状管网调压器出口压力的计算方法来确定环状管网的调峰压力,其原理是通过调峰系数和在调峰系数为1时调压器出口到用户之间管路的额定压降来确定调蜂压力。使用这种方法,运行管理单位只需根据设计提供的额定工况下环状管网水力计算结果和最大小时流量,便可以根据调峰系数容易地确定调压器出口压力。

The article introduces a simple method for calculating peak pressure of loop network. The principle of the calculation method using branch network regulator's outlet pressure, which defines peak pressure of loop network, is to determine peak pressure with peak coefficient and rated pressure drop from regulator's outlet at peak coefficient of 1. By this method, operation management unit can define the pressure at regulator's outlet easily according to peak coefficient on the basis of hydraulic calculation result of loop network at rated operation status designed and max. hour flow rate.
