热水供暖系统的水压图及水力工况

Pressure Diagram and Hydraulic Regime of Hot-water Heating System

热水供暖(热)系统的水压图可以清晰地表示出热水管路中各点的压力,根据它不仅可以正确地确定热水供暖(热)系统的设计方案;同时,还可以通过实测水压图发现供暖(热)系统运行时管网中存在的问题。本文将分3次连载论述有关热水供暖(热)系统设计和运行中有关“水压图和水力工况”问题,期望它能有利于达到最佳的供暖(热)效果。

The pressure diagram of hot-water heating system denotes pressure of each point in heating tubes clearly. According to the pressure diagram, not only the design project of heating system can be confirmed correctly, but also the problems can be found out while the heating system running. This article is first one of three serial papers which discuss the 'pressure diagram and hydraulic regime' in the design and running of hot-water heating system network, looking forward to optimum heating propose.
