在老厂技术改造中,能源的计量十分必要。当测量两个支管的蒸汽流量时,由于从锅炉来的饱和蒸汽压力波动较大(4～8.5kgf/cm~2表压),对蒸汽流量的测量值有很大影响。而总管没有设置压力调节系统,如不进行压力自动补偿,势必造成蒸汽计量测量不准确。为此,我们设计了下述蒸汽流量压力自动补偿系统。该系统的特点是使用仪表少,经济可靠,补偿方法简单、实
In the old factory technological transformation, energy measurement is necessary. When measuring the steam flow rate of two branch pipes, the measurement of the steam flow rate greatly influences the large fluctuation of the saturated steam pressure from the boiler (4 to 8.5 kgf / cm 2 gauge pressure). The Explorer does not set the pressure regulating system, if not automatically compensate for pressure, will inevitably lead to steam metering measurement inaccurate. To this end, we have designed the following steam flow pressure automatic compensation system. The system is characterized by the use of less instruments, economical and reliable, the compensation method is simple and real
