摘　　要：针对末端换热站,一次网侧流量不足、供水温度低、换热效果差、不能满足末端用户热量需要等问题,利用一、二次网间的大压差,在一、二次网间安装水喷射泵,取代换热器和二次网循环水泵,既增加了一、二次网的换热效果,也增大了一次网的供回水温差,从根本上解决了一次网流量不足带来的热量不足问题。The end of the heat exchange station,a network of lateral flow shortage,low water temperature of the heat exchange efficiency is poor,can not meet the energy needs of their end users,using the first and second gateway in the large pressure difference,in the first and second network installed between the water jet pump,heat exchanger and the second network to replace circulating pump,an increase of the first and second net effect of heat transfer,but also a net increase for the return water temperature difference,a fundamental solution to a lack of network traffic the heat from the shortage.The results show that：this method is technically feasible and economically reasonable use of resources to improve energy efficiency.Realize a large temperature difference of economic operation of small flow,reaching to save money,energy saving,the purpose of safe operation.In particular,lack of transportation capacity on the pipeline and pipe network extension has some reference value.
