350MW机组重油测量系统的改进及实现

Improvement and Realization on Heavy Oil Measurement System of 350MW Unit

主要讨论了重油流最采样信号的方式影响信号正常显示的因素,并提出了相应的改进措施。在采用隔膜式差压变送器进行取样并提前干预影响测量效果的各种影响因素后,重油这一特殊介质的采样可靠性得到了保证。

Some problems of heavy oil measurement system like sampling form and other factors, and the corresponding improvement measures are discussed in this paper. After tested the improvements, such as adoption of the diaphragm sealed differential pressure transmitter as the sampling form and pre-interventions of impact factors of measurement, the heavy oil sampling is reliability in the intermittent operation process.
