结合兰州石化公司油品储运厂达西批发站目前油品装车实际情况,从现用零装管路布置、装车工艺及机泵运行启停方面进行了分析。基于油品装车机泵较多,但实际使用机泵较少,且装车过程中运行时间不太长,起停比较频繁的使用特点,提出了在油品装车系统增加机泵变频器方法并优化使用,通过PLC实现整个系统自动控制,该方法可以达到降低投资,提高变频器在油品装车系统中的使用效率的效果。同时解决装车管线压力变幅大的问题,使整个运行系统实现节能的要求。
According to the actual situation of oil loading at Darcy Station of Lanzhou Petrochemical Company Oil Storage and Transportation Factory, the paper analyzes the layout, loading technology and starting and stopping of pump operation. Based on the oil loading pump more, but the actual use of less pump, and the loading time is not running long, starting and stopping more frequent use of characteristics, put forward in the oil loading system to increase the pump inverter Method and optimize the use of automatic control of the entire system through the PLC, the method can achieve the effect of reducing investment, improve inverter efficiency in the oil loading system. At the same time to solve the loading pipe pressure fluctuation problem, so that the entire operating system to achieve energy-saving requirements.
