II. In-Depth Analysis of Working Principles

1. Stable Gas Source Connection and Pressure Reduction: During use, the oxygen filling device is first tightly connected to a high-pressure pure oxygen cylinder via a dedicated connecting pipeline. The high-pressure oxygen from the cylinder (typically at 12-15 MPa) enters the device and passes through a built-in high-precision pressure reducing valve. This valve accurately reduces the pressure of the high-pressure oxygen to a range suitable for oxygen bomb filling, preventing direct high-pressure oxygen impact on the bomb and ensuring the safety and stability of the entire filling process.

1. Precise Pressure Regulation and Setting: The oxygen filling device is equipped with a highly sensitive precision pressure gauge with a range of 0-4 MPa and an accuracy of up to 0.02 MPa or higher. Laboratory personnel can easily and accurately set the oxygen filling pressure using an adjustment knob based on the combustion characteristics of different samples and the specific requirements of the automatic calorimeter. For example, when measuring the calorific value of coal, the oxygen filling pressure is generally set between 2.8-3.0 MPa to ensure complete combustion of the coal sample inside the oxygen bomb.

1. Reliable Oxygen Bomb Connection and Filling: The oxygen bomb containing the sample is tightly connected to the oxygen filling device through a specific interface designed with sealing technology to prevent oxygen leakage during the filling process. Once connected, the oxygen filling valve is opened, and the pressure-reduced and stabilized oxygen is slowly injected into the oxygen bomb at the set pressure and flow rate through the filling pipeline. During the process, laboratory personnel can monitor the pressure changes in real-time using the precision pressure gauge to ensure the pressure remains stable within the set range. Once the pressure reaches the predetermined value, the oxygen filling valve is closed, completing the filling operation.

1. Comprehensive Pressure Relief and Safety Protection: After completing the oxygen filling operation and using the oxygen bomb, it is necessary to safely release any residual high-pressure oxygen in the device and the bomb. The oxygen filling device is equipped with a dedicated pressure relief valve. Laboratory personnel only need to gently open the valve to allow the oxygen to slowly discharge, gradually reducing the pressure to a safe range. Additionally, to prevent abnormal pressure increases during the filling process, the device is also equipped with an overpressure protection mechanism. If the pressure exceeds the device's maximum rated pressure (e.g., 4.5 MPa), the overpressure protection will automatically activate, quickly opening the safety valve to release pressure, avoiding safety accidents caused by excessive pressure, and ensuring the safety of personnel and the normal operation of the equipment.

IV. Standardized Guidance for Actual Operation Process

1. Meticulous Preparation Work: Before using the oxygen filling device, carefully check the oxygen reserve in the cylinder to ensure sufficient oxygen for the experiment. At the same time, thoroughly inspect the connections of all components of the device, especially the connections to the oxygen cylinder and the interface with the oxygen bomb, to ensure they are secure and leak-free. Additionally, check whether key components such as the precision pressure gauge, pressure reducing valve, oxygen filling valve, and pressure relief valve are functioning properly. If any abnormalities are found, they should be repaired or replaced promptly.

1. Rigorous and Standardized Oxygen Filling Operation: First, slowly open the valve of the oxygen cylinder. At this point, the high-pressure gauge will显示 the oxygen pressure inside the cylinder. Then, by adjusting the pressure调节螺杆 on the pressure reducing valve, gradually bring the指示 pressure on the low-pressure gauge to the set value required for the experiment, such as 2.8-3.0 MPa. Next, place the oxygen bomb containing the sample steadily in the designated position of the oxygen filling device, aligning the bomb's air inlet with the device's air nozzle accurately. Subsequently, press down the oxygen filling handle to begin the filling operation. During the process, closely monitor the数值 changes on the precision pressure gauge to ensure the filling pressure rises steadily and eventually reaches the set value. The filling time is generally controlled at around 30-45 seconds to ensure sufficient oxygen is filled into the bomb. After filling is complete, slowly release the filling handle. At this point, the valve core on the oxygen bomb should be observed to protrude upward, indicating successful oxygen filling.

1. Safe and Orderly Pressure Relief Treatment: After using the oxygen bomb, it is necessary to release any residual high-pressure oxygen in the device and the bomb. First, remove the oxygen bomb from the automatic calorimeter and place it in a safe and stable location. Then, slowly open the pressure relief valve of the oxygen filling device to allow the oxygen to discharge slowly. During the pressure relief process, operators should stand to the side of the pressure relief valve to avoid injury from ejected oxygen. At the same time, observe the数值 on the precision pressure gauge. When the pressure drops to zero, it indicates that pressure relief is complete. At this point, close the pressure relief valve to finish the entire oxygen filling and pressure relief operation process.

V. In-Depth Analysis of Maintenance Key Points

1. Key Component Maintenance:

• Pressure Gauge Calibration: The precision pressure gauge is a key component for controlling the oxygen filling pressure, and its accuracy directly affects the reliability of experimental results. Therefore, it is recommended to regularly send the pressure gauge to a professional metrology检测机构 for calibration, typically at least once a year, to ensure its指示数值 are accurate. If any malfunction or error beyond the allowable range is found during calibration, it should be repaired or replaced promptly.

• Valve Maintenance: During long-term use, the oxygen filling valve and pressure relief valve may experience issues such as poor sealing or valve sticking. Therefore, regular maintenance of the valves is necessary. Use an appropriate amount of lubricating oil to lubricate the moving parts of the valves, ensuring they operate smoothly. At the same time, check the sealing performance of the valves. If the sealing components are aged or damaged, replace them with new ones promptly to ensure the valves remain sealed during oxygen filling and pressure relief, preventing oxygen leakage.

• Pipeline Inspection: The connecting pipelines of the oxygen filling device承担 the important task of transporting oxygen, and their safety is crucial. Regularly inspect the pipelines for bending, cracking, aging, etc. If any issues are found, replace the pipelines immediately to avoid oxygen leakage due to pipeline rupture during filling, which could lead to safety accidents. Additionally, when connecting pipelines, ensure the connections are secure and well-sealed to prevent oxygen leakage due to loose connections.

1. Storage Environment Requirements: When the oxygen filling device is not in use, it should be stored in a dry, ventilated, and cool environment, avoiding direct sunlight and high temperatures.
