摘　　要：为了更好地模拟湿气两相流体的流动状态，开展基于不同湿气流量测量原理和方法的实验室研究，天津大学流量实验室设计和建造了可调压中压湿气实验装置.该装置设计压力为4,MPa，采用标准表法双闭环式设计，包含独立气体循环管路、独立液体循环管路和实验用混合管路.实验所用介质为空气和水，最高工作压力1.6,MPa，可实现气相流量范围3～1,000,m3/h，液相流量范围0.05～8.00,m3/h.本研究包括该装置结构设计、压损计算、关键设备选型、装置电气控制系统设计和调试等，并通过对系统不确定度分析，得到该可调压中压湿气装置气相测量不确定度为1.00%，液相测量不确定度为0.35%.In order to better simulate the flowing condition of wet gas and develop laboratory studies based on differ-ent wet-gas flow measurement principles and methods,the flow laboratory of Tianjin University designed and built the wet gas experimental facility with adjustable and intermediate pressure. The designed pressure of the facility is 4,MPa,using the design of standard meter method and dual closed-loop. It includes an independent gas circulation loop,an independent liquid circulation loop and an experimental mixed pipeline. The experimental medium is air and water,and the highest working pressure is 1.6,MPa. The gas flow rate range is 3-1,000,m3/h,and the liquid flow rate range is 0.05-8.00,m3/h. The study includes the structure designing of the facility,the calculation of pressure loss,the selection of key equipment,the facility electrical control system designing and debugging,etc. Based on the uncertainty analysis of the facility,It is concluded that the facility’s gas measurement uncertainty is 1.00%and its liquid measurement uncertainty is 0.35%.
