多种油品沿一根管道顺序输送时,两种油品界面间必然生成混油,若在两种油品间投放橡胶隔离球(塞)则能减少混油的生成。为此,各泵站必须能及时地判断混油段和隔离球的到来,以指导各泵站的操作和在终点站准确切割成品油及混油。“油品检测仪”就是各泵站完成此项任务的必备的关键设备之一。在轰轰烈烈的“批林整风”运动的推动下,由上海超声波仪器厂负责,同济大学协 When a variety of oils are transported in sequence along a pipe, a mixed oil is inevitably generated between the two oil interfaces. If a rubber isolation ball (plug) is placed between the two oils, the generation of mixed oil can be reduced. To this end, the pumping station must be able to promptly determine the arrival of mixing section and isolation ball to guide the operation of the pumping station and the precise cutting of refined oil and mixed oil at the terminal. “Oil Detector” is one of the key equipment necessary for each pump station to accomplish this task. Driven by the vigorous campaign of “Approaching Forestry rectification”, Shanghai Ultrasound Instrument Factory is responsible for the cooperation of Tongji University
