一、前言随着我国社会主义建设事业的高速发展和工业生产自动化水平的迅速提高,我们厂对精确掌握生产过程中的各流量参数及减少管路损耗的要求也越来越高,以便进行经济核算,降低煤耗,节省用电。目前厂里一机一炉的蒸汽流量就要用二块或四块孔板,加给水,凝水等就要近十块孔板,每当机炉大修就要拆下检查,拆装时体力劳动极为繁重。而且法兰一漏就要停机停炉拆下重装,浪费劳动力,还影响发电。这些孔板都是用不锈钢或~#20钢加工,耗费贵重金属和
I. Introduction With the rapid development of China’s socialist construction and the rapid increase in the level of automation in industrial production, our factory has become increasingly sophisticated in accurately grasping the various flow parameters in the production process and reducing pipeline losses in order to carry out economic Accounting, reduce coal consumption, save electricity. At present, a factory of a steam flow furnace will use two or four orifice plate, add water, condensate and so on to nearly ten orifice, whenever the furnace overhaul will be removed to check, disassembly, physical strength Labor is extremely heavy. Flange and a leak will shut down furnace removed heavy equipment, waste of labor, but also affect the power generation. These plates are made of stainless steel or # 20 steel, consuming precious metals and metals
