| 摘 要： | 建立了环状管网水力工况的数学模型,给出限额供热的压头校核公式。以某环状管网为例,当某管段发生故障,采用非限额供热时,距热源较远的用户流量过小,无法满足最低供热量;采用限额供热时,可实现各热用户供热均衡。对正常工况及限额供热工况的水压图进行了分析比较。当环状管网干线发生故障时,宜采取限额供热。

| Abstract: | The mathematical model of hydraulic regime of ring-shaped heat-supply network is established,and the pressure head check formula for quota heating is given.Taking a ring-shaped heat-supply network for example,when non-quota heating is used due to fault of a pipeline section,the flow rate obtained by heat users being away from heat source is too small to satisfy the lowest heating requirement;when quota heating is used,the heating balance of all heat users can be attained.The pressure diagrams of normal condition and quota heating condition are compared.The quota heating should be used when a fault takes place at the main of ring-shaped heat-supply network. |
