流量测量节流装置用孔板喷嘴和文丘里管测量充满圆管的流体流量 - It is concluded that it may be disadvantageous to capacity modulation at low temperature environment if the condenser area is smaller and throttle set is capillary . 3
结果表明：系统在冷凝器面积偏小和采用毛细管作节流装置的前提下，不利于低温环境下的容量调节。 - Abstract : various measurement methods of the capacity of gas discharge forpiston type compressor are analized and compared . the orifice choke device that is suitable for measurement in site is recommended emphatically . in combination with the example of measurement in site , the matters needing attention of measurement in site on the capacity of gas discharge for compressor are point out
文摘:对活塞式压缩机排气量的各种测量方法进行了分析比较，着重介绍了比较适合于现场测量的孔板节流装置，并结合现场测量实例指出了压缩机排气量现场测量应注意的问题。 - It has a long history using a throttle device to measure the flow volume of fluid in pipe the method has formed normalization at home and abroad the principle is to make the flow bunch form the particial shrink at the place where the throttle part is located so as to produce a static pressure difference then measure and calculate the flow volume at the moment when the fluid is flowing through the throttle device by the static pressure measured this method is based on the law of conservation of energy and the equation of flow continuity
用节流装置测量管道中流体流量已历史悠久，在国内、国际上都已标准化，其原理是使流束在节流件处形成局部收缩，产生静压力差，通过测量静压力差来衡量流体流过节流装置时的流量大小，这种测量方法是以能量守恒定律和流动连续性方程为基础的。
