随着标准节流装置和计算机的进一步发展,大量设计管理软件的出现代替了繁重的人为迭代计算,避免了引入很多人为误差,推动了标准节流装置的发展,但是也随之带来一些问题。下面就实际检定工作中发现的问题作一讨论。一、设计软件计算错误假定未经标定的节流装置与已经经过充分试验标定的节流装置几何相似和动力学相似,亦即符合

With the further development of standard throttling devices and computers, the emergence of a large amount of design management software replaces the heavy artificial iterative calculations, avoids the introduction of many human errors and promotes the development of standard throttling devices, but also brings about some problems . Here’s the actual verification of the problems found in the work to make a discussion. First, the design software calculation error Assuming that the uncalibrated throttling device has been fully tested and calibrated throttling device geometrically similar and dynamic similar, that is, in line with
