Maintenance and upkeep are crucial for ensuring the safety of low-temperature storage tanks. Here are some common maintenance measures:
Regular Inspections: Conduct regular checks on low-temperature storage tanks, including inspections of the exterior, internal structure, and corrosion-resistant coatings. Look for cracks, corrosion, wear, and other issues, and identify and repair potential safety hazards in a timely manner.
Cleaning and De-icing: Regularly clean the external surface and internal structure of the low-temperature storage tank to remove accumulated dirt and ice layers. The accumulation of ice can lead to structural damage and corrosion, while cleaning and de-icing can extend the lifespan of the tank.
Level Monitoring: Regularly monitor the liquid level in low-temperature storage tanks to ensure it remains within a safe range. Excessive or low levels can lead to overpressure or over-vacuum in the tank, increasing safety risks.
Leak Detection: Install a leak detection system and regularly inspect for leaks in low-temperature storage tanks. Leaks can lead to the release and evaporation of liquids or gases, increasing safety risks.
Corrosion Protection Measures: Implement appropriate corrosion protection measures, such as coating protection and corrosion-resistant coatings, to safeguard the metallic structure of low-temperature storage tanks from corrosion damage.
Emergency Fault Handling: Establish an emergency fault handling mechanism to promptly address and repair issues with low-temperature storage tanks, preventing accidents from occurring or escalating.
Training and Development of Personnel: Train and develop operation and maintenance personnel to ensure they possess relevant knowledge and skills for the correct operation and maintenance of low-temperature storage tanks.
It's important to note that maintenance should be tailored to the specific type of tank and operating conditions, adhering to relevant local laws, regulations, and standards. During the maintenance process, it is recommended to consult with engineers or guidance from relevant institutions to ensure the tank's safety and reliability.

When selecting the base for a liquid argon tank, consider the following factors:
Load Capacity: The support must be able to bear the weight of the liquid argon tank. Select a support with sufficient 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 rocking during use. The design of the support should take into account the center of gravity of the tank and its changes to ensure stable support.
Corrosion Resistance: Liquid argon has low temperature and corrosive properties; the support material should have good corrosion resistance to prevent corrosion and damage. Common support materials include stainless steel, aluminum alloy, etc.
Insulation: Liquid argon storage tanks generally require insulation to maintain temperature, with the supports needing to possess certain insulating 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 bracket should be designed for ease of installation and maintenance, facilitating the tank's installation and routine maintenance tasks.
When selecting the support for liquid argon tanks, it's advisable to consult with engineers or suppliers. Choose an appropriate support based on the specific tank requirements and operating environment. Additionally, adhere to relevant design codes and safety standards to ensure the quality and reliability of the support.
