锅炉额定工作压力不同,所选配压力表的量程和精度也不同。额定工作压力越高,要求配制的压力表的量程越大,一般精度要求也有所提高。 当前,中小型工业锅炉普遍存在降压运行问题。降压运行的原因一是实际生产、生活及采暖所需的工作压力小于锅炉额定工作压力;二是由于锅炉本体或 Boiler rated working pressure is different, the selected pressure gauge range and accuracy are also different. The higher the rated working pressure, the larger the range of pressure gauges that are required to be formulated, the higher the general accuracy requirements. At present, small and medium-sized industrial boilers are generally under pressure to run the problem. One of the reasons for the buck operation is that the working pressure required for actual production, living and heating is less than the rated working pressure of the boiler; the second is that the boiler body or
