摘　　要：多功能通风部件试验台是以风量与压差测定两大功能为基础、集多种测试功能的测定装置,是一套通用、便捷的通风部件测试系统。主要分析了该试验台中系统压力损失,并对喷嘴流量计的压力损失做了着重的分析,通过理论及实验数据进行较深入的研究,得出了试验台中多型号组合式喷嘴流量计的应用范围与试验台模块化控制优化方案。As one of the high efficiency and convenient testing system of ventilating parts, muhi-functional experimental instrument is based on the air-quantity and Pressure drop. The result of optimization on multi-nozzle flowmeter and the blocking controlling of experimental instrument have been concluded through the analyses of Pressure drop on the nozzle flowmeter and the experimental dates.
