摘　　要：供热用可调节型水喷射泵可有效解决集中供热管网水力失调引起的末端用户热力失调的问题。本文介绍了水喷射泵的基本构造及运行原理,并于2018年供暖季对北京市通州区3个小区的运行效果及节能量进行实测。根据实测结果可知,应用可调节型水喷射泵时供热系统呈现“大温差、小流量”的运行状态,具有较好的节能效果。The adjustable water jet pump for heating can effectively solve the problem of thermal imbalance of end users caused by hydraulic maladjustment of the centralized heating pipe network.In this paper,the basic structure and operation principle of the water jet pump are presented,and the operation effect and energy saving of three residential areas in Tongzhou District of Beijing are measured during the heating season of 2018.According to the measured results,the application of the adjustable water jet pump heating system shows the operation state of“large temperature difference and small flow”,which has a better energy saving effect.
