【摘要】:GB／T2624的本部分规定了喷嘴和文丘里喷嘴的几何尺寸和安装在管道中测量满管流体流量的使用方法(安装和工作条件)。GB／T2624的本部分亦提供了用于计算流量并可配合GB／T2624．1规定要求一起使用的相关资料。GB／T2624的本部分适用于在整个测量段内流林保持亚音速流动,且可被认为是单相流的喷嘴和文丘里喷嘴。此外,每种装置只能用于规定的管道尺寸和雷诺数。本部分不适用于脉动流的测量。本部分不涉及喷嘴和文丘里喷嘴在尺寸小于50mm或大于630mm,或管道雷诺数低于10000的管道中的使用。GB／T2624的本部分涉及a)两种型式的标准喷嘴；1)ISAl932喷嘴；2)长径喷嘴。b)文丘里喷嘴。这两种型式的标准喷嘴有着很大的差别,所以本部分分别予以叙述。文丘里喷嘴的上游端面与ISA1932喷嘴相同,但它有一个扩散段,所以下游取压口的位置不同,因此单独予以叙述。这种结构的压力损失比类似的喷嘴低。两种标准喷嘴和文丘里喷嘴都做过直接校准实验,实验的数量、分布范围和质量足以保证相关应用系统能以具有一定的可预测不确定度限值的校准实验结果和系数作为依据。

Product Code:SAE J2931/7
Title:Security for Plug-in Electric Vehicle Communications
Issuing Committee:Hybrid - Ev Committee
Scope: Develop and document the functional and technical requirements for a standard telematics application programming interface that facilitates two way communications between the PEV telematics service provider and the Energy Services Provider. The telematics interface will provide access to consumer specific usage data e.g. instantaneous usage, consumption usage, volts, amps, VAR, power factor, etc. The telematics common interface solution will encompass, at minimum, four key interfaces: Aggregation, Control, TOU Rates, and Vehicle Information inclusive of interconnectivity with utility energy management systems, utility back office networks, ISOs, RTOs, and consumer home area networks. Use Cases are to be developed to define the attributes of key interface requirements and functionality. Requirements for implementation shall include compliance and/or interoperability with J2847 series of recommended practices, and with Smart Energy Profile 2.0 and/or OpenADR/OpenADE application standards.
