The use and operation of the liquid oxygen storage tank system require attention to the following points:
Safe Operation: When operating the liquid oxygen storage tank system, it is mandatory to follow relevant safety operation procedures and standards to ensure the safety of the operators.
Tanks Selection: Choose liquid oxygen tanks that meet specifications and standards, ensuring their quality and safety performance.
Tank Installation: Tanks should be installed on a solid foundation to ensure stability. Additionally, good ventilation around the tank is required, and it should be kept away from flammable materials and heat sources.
Sealability Inspection: Regularly check the sealing performance of the storage tank system to ensure there are no leakage issues at valve and pipeline connections.
Pressure Control: Storage systems should be equipped with pressure gauges and safety valves, with regular inspections and maintenance to ensure pressure remains within safe limits.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and is prone to causing fires. Install fire walls around the storage tank system, prohibit smoking and open flames, and ensure safety.
Static Dissipation: During the operation of the liquid oxygen system, static electricity may cause sparks, increasing the risk of fire. Measures such as using static-conductive materials and anti-static equipment are taken to reduce the accumulation and release of static electricity.
Regular inspections and maintenance: Conduct regular checks on the tank system and related equipment, including valves, pipes, pressure gauges, etc. Ensure that the equipment is in good condition without any damage, and promptly repair or replace any damaged parts.
Waste Gas Treatment: The use of the liquid oxygen system generates waste gas, which requires appropriate waste gas treatment measures to minimize environmental impact.
Above are the points to be noted when using the liquid oxygen storage tank system, ensuring safe operation and the normal functioning of the system. During operation, strictly follow the relevant operational procedures and safety requirements to avoid accidents.

To prevent risks associated with liquid oxygen storage tanks, the following preventive measures can be taken:
Safety Operations and Management: Establish and enforce stringent safety operations and management systems, including proper use of storage tanks, operational procedures, and safety training. Ensure operators possess the necessary safety awareness and skills, adhere to operational procedures, and minimize operational errors and the likelihood of accidents.
Regular Inspections and Maintenance: Conduct regular inspections and maintenance on liquid oxygen tanks, including visual inspections, pressure tests, and leak detection. Promptly identify and address any issues with the tanks to ensure their safety and reliability.
Safety devices and protective equipment: Tanks should be equipped with necessary safety devices, such as pressure relief valves, level alarms, etc., as well as protective equipment, like fire walls, explosion-proof equipment, etc. These devices and equipment can take timely measures in abnormal situations to ensure the safety of the tank.
Fire Prevention Measures: Liquid oxygen contains a high oxygen content, which is prone to causing fires. Therefore, fire prevention measures such as firewalls and fire extinguishers should be set up around the storage tanks to prevent the spread and expansion of fires.
Leakage Control and Emergency Response Plan: Establish a leakage control and emergency response plan for liquid oxygen storage tanks, including leakage control measures, emergency response procedures, and evacuation plans. In the event of a leakage incident, the plan allows for prompt actions to control the leak and ensure personnel safety.
Training and Awareness Enhancement: Conduct regular safety training for personnel using liquid oxygen tanks to enhance their safety awareness and emergency response capabilities. Strengthen safety

When selecting the support for a liquid argon tank, consider the following factors:
Load Capacity: The support must be capable of bearing the weight of the liquid argon tank. Select a support with adequate load capacity based on the tank's capacity and dimensions. Typically, the weight of the liquid argon tank is specified in the design specifications, allowing for the determination of the support's load capacity.
Stability: The support must provide sufficient stability to prevent the tank from tilting or swaying during use. The design of the support should consider the tank's center of gravity and its changes to ensure stable support.
Corrosion Resistance: Liquid argon has low temperature and corrosive properties, so the support material should have excellent corrosion resistance to prevent corrosion and damage. Common support materials include stainless steel, aluminum alloy, etc.
Insulation: Liquid argon storage tanks generally require thermal insulation, with the supports needing to possess certain insulation properties to minimize heat transfer and evaporation of the liquid argon. The design of the supports should consider the installation and protection of the insulation layer.
Installation and Maintenance: The support should be designed for ease of installation and maintenance, facilitating the tank's installation and routine maintenance tasks.
When selecting the support for a liquid argon tank, it's advisable to consult with engineers or suppliers. Choose the appropriate support based on the specific tank requirements and usage environment. At the same time, adhere to relevant design specifications and safety standards to ensure the quality and reliability of the support.
