负责同志: 您刊81年第六期中刊登关于“孔板质量已有较大程度的提高”一文中,提到孔板加工工艺的改进对提高测量精确度有很大好处,并对安装节流装置应注意的问题作了简要概述,阅后很感兴趣。目前我厂为进一步加强节能工作,提高经济核算,对蒸汽流量测定提出了进一步的要求。为提高蒸汽流量的测量精确度,加强各单位维修、保护工作,故特请您们能否将提高孔板加工质量方面的先进工艺,技术要求;孔板计算以及安装节流装置方面的有关技术资料提供给我们,特表感谢。
Comrades in charge: You published in the sixth issue of 81 on the “In the quality of the plate has been greatly improved ” article, referred to the improvement of the orifice plate processing technology to improve the measurement accuracy of great benefit, and the installation Throttle device should pay attention to the problem made a brief overview, read very interested. At present, I plant to further enhance energy conservation, improve economic accounting, the steam flow measurement put forward further requirements. In order to improve the measurement accuracy of steam flow and enhance the maintenance and protection work of all units, please ask whether you will be able to improve the advanced technology and technical requirements in the processing of orifice plate; the calculation of orifice plate and related technology in the installation of throttling device Information provided to us, special thanks.
