The oil storage tank 301, the first centrifugal pump 302 and the first organic glass tube 303 constitute a diesel circulation pumping system.

[0051] The method for using the diesel pipeline transportation monitoring device of this embodiment includes the following steps:

[0052] ① Experimental preparation: Ensure that the loading hopper 101, vertical pipeline, horizontal pipeline and oil storage tank 301 are clean and well connected; check whether the speed reducer is correctly installed in the vertical pipeline, and confirm that the monitoring equipment such as pressure sensor and pressure sensor are functioning normally.

[0053] ② Hopper operation: Confirm that the ball valve 103 below the hopper 101 is closed, add diesel into the hopper through the oil inlet at the top of the hopper 101, and ensure that the air release valve is open to remove the air in the hopper 101.

[0054] ③ Experiment starts: Start the computer monitoring software and start recording data. Close the vent valve 102 and start the second centrifugal pump 104 to extract diesel from the oil storage tank 301 and input it into the loading hopper 101 through the pipeline. Open the ball valve 103 and adjust the flow of the second centrifugal pump 104 to allow the diesel to flow downward from the loading hopper through the vertical pipeline.

[0055] ④ Flow monitoring: Observe the flow of diesel through the vertical pipeline to ensure the smooth flow of diesel and avoid the generation of a large number of bubbles or long-term non-full pipe delivery. Monitor the data of pressure sensors at various locations and bottom pressure sensors in real time to evaluate the pressure distribution and impact force of diesel in the pipeline. Adjust the number or distribution of speed reducers according to the monitoring data to optimize the flow rate of diesel and reduce the impact pressure.

[0056] ⑤ Pressure monitoring: Record the pressure and flow data during the experiment for subsequent data analysis and evaluation. Analyze the data to determine the performance of the device and the stability of the diesel delivery process, and make adjustments if necessary to improve system performance.

[0057] ⑥ End of the experiment: After the experiment is completed, the flow rate of the second centrifugal pump 104 is gradually reduced, and the second centrifugal pump 104 is turned off to stop the circulation of diesel. The air release valve 102 is opened to safely discharge the remaining diesel in the hopper, and the equipment is cleaned and maintained.

[0058] The working principle of the diesel pipeline transportation monitoring device of this embodiment includes:

[0059] ① Flow rate control: The diesel flow rate can be slowed down by installing a speed reducer in the vertical pipe. These devices provide resistance, reduce the flow rate of diesel, and reduce the impact of diesel on the bottom of the vertical pipe.

[0060] ②Pressure monitoring and distribution: Multiple pressure sensors are installed in the vertical pipeline. These sensors are arranged at different heights along the pipeline to monitor and record the pressure changes and distribution in the entire pipeline, which helps to analyze the characteristics of diesel flow and pressure fluctuations, and then adjust the operating parameters to optimize the transportation process.

[0061] ③ Visual observation: Use transparent acrylic material to construct the vertical pipe so that the flow state of diesel can be directly observed, allowing operators to intuitively judge the flow state of diesel (full pipe or partly full pipe delivery) and monitor whether there are a large number of bubbles that may pose a safety hazard.

[0062] ④Circulation system design: By connecting the oil storage tank, centrifugal pump and loading hopper into a closed loop system, diesel can be circulated in the system. The centrifugal pump extracts diesel from the oil storage tank and then transports it back to the loading hopper, thereby continuously supplying the diesel transportation experiment in the vertical pipeline to ensure continuous operation.

[0063] The diesel in the hopper of the diesel pipeline transportation monitoring device of this embodiment is transported downward through the pipeline, passes through the vertical pipeline and the horizontal pipeline, flows through the flow meter at the elbow to monitor the flow of diesel, and is finally collected in the oil storage tank. The centrifugal pump pumps the diesel from the oil storage tank back to the hopper to form a cycle. The pressure sensor and flow meter monitor the pressure and flow changes of the diesel in real time, and record and analyze the data through the connected computer, which can visually observe the changes of diesel in the pipeline, provide important data support for optimizing the pipeline design, provide a basis for the parameter design and distribution of the speed reducer, and can comprehensively improve the stability and safety of the downward transportation of diesel.
