针对原油储罐的特殊环境和条件 ,采用数字化测温和工业总线技术 ,研制开发了储油罐原油温度实时监测报警系统 ,并利用该系统对原油储罐温度分布规律进行了较详细的研究。介绍了该系统的组成以及研制和开发的主要工作。同时 ,在分析大量温度数据的基础上 ,得出了储油罐原油温度分布规律。 Aiming at the special environment and conditions of crude oil storage tanks, a digital temperature measurement and industrial bus technology were used to develop a real-time monitoring and alarm system for crude oil temperature in storage tanks. The temperature distribution of crude oil storage tanks was studied in detail using the system. Introduced the composition of the system and the main work of research and development. At the same time, based on the analysis of a large number of temperature data, the temperature distribution of crude oil in storage tank is obtained.
