The sealed conveying process refers to a connection method where all intermediate pumping stations along the long pipeline are in a closed state. All engine oil from the previous pumping station will enter the pump at this station. There are no buffer tanks connected to a large amount of steam at intermediate stations. The entire oil path is sealed, simplifying the process flow, reducing the number of equipment, and eliminating the evaporation loss from side oil tanks. The intermediate pumping stations along the entire line form a unified hydraulic system. The pressure at each station can be adjusted relative to one another, thereby reducing the energy consumption for regulation and allowing for appropriate control of the entire pipeline. However, any failure at an intermediate pumping station will immediately affect the operation of the entire pipeline, so the equipment, communication, and automatic control system must be sensitive and reliable.
Each intermediate pump station connection maintains a closed transmission flow over long-distance pipelines, which is sealed. All the engine oil from the previous pump stations is transported to this station for oil handling...Inter-allocation can reduce adjustable energy consumption by automatically controlling the entire pipeline. However, any failure in the intermediate pump stations will immediately impact the operation of the entire production line, thus requiring sensitive and reliable equipment, communication, and automatic control systems.
