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 issues such as cracks, corrosion, and wear, and promptly identify and repair potential safety hazards.
Cleaning and Deicing: Regularly clean the exterior surface and internal structure of low-temperature storage tanks to remove accumulated dirt and ice layers. The buildup of ice can lead to structural damage and corrosion, while cleaning and deicing can extend the lifespan of the tank.
Level Monitoring: Regularly monitor the liquid level of low-temperature storage tanks to ensure it stays within the safe range. Excessive or insufficient levels can lead to overpressure or vacuum in the tanks, increasing safety risks.
Leak Detection: Install a leak detection system to regularly check 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 failures in low-temperature storage tanks, in order to prevent accidents from occurring or escalating.
Training and Development: Train and develop operators and maintenance personnel to ensure they possess relevant knowledge and skills for the proper 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's advisable to consult with engineers or guidance from relevant institutions to ensure the tank's safety and reliability.

Low-temperature liquid oxygen storage tanks typically require certain safety accessories to ensure safe operation and to address potential risks. The following are some common safety accessories for low-temperature liquid oxygen storage tanks:
Pressure Sensor: Used to monitor pressure changes within storage tanks. If the pressure exceeds the set range, it will trigger an alarm or automatically stop filling measures to prevent overpressure in the tank.
Safety Valve: Used to automatically release gas when the pressure inside the storage tank exceeds the set value, preventing overpressure. The safety valve should be selected and installed based on the design pressure and capacity of the storage tank.
Pressure Relief Device: Used to release gas to a safe area when the pressure inside a storage tank is too high, thereby reducing the pressure on the tank. The pressure relief device typically includes relief valves, relief pipes, etc.
Level sensor: Used to monitor the liquid oxygen level changes within the storage tank, ensuring sufficient liquid oxygen and preventing overfilling.
Temperature Sensor: Used to monitor temperature changes within storage tanks to ensure the temperature of liquid oxygen inside remains within a safe range.
Fire Detection and Fire Suppression Systems: Designed to monitor fire risks surrounding storage tanks and activate the fire suppression system when necessary, to prevent the spread of fires to other areas.

The medical oxygen steel cylinder refilling facility, in addition to the liquid oxygen storage tanks, includes the following components:
Oxygen Compressor: Oxygen compressors are used to compress gaseous oxygen into high-pressure oxygen. These compressors are typically made with special materials and designs to ensure safe handling and compression of oxygen.
Oxygen Purification System: The oxygen purification system is designed to remove impurities and contaminants from oxygen to ensure the purity and quality of the supplied oxygen. The system typically includes filters, adsorbents, and molecular sieves.
Oxygen Storage System: In addition to liquid oxygen tanks, the oxygen filling area may also include a gaseous oxygen storage system, used for temporary storage and supply of gaseous oxygen. The gaseous oxygen storage system typically includes high-pressure oxygen cylinders or gas storage tanks.
Filling Equipment: Filling equipment is used to transfer oxygen from liquid oxygen storage tanks or gaseous oxygen storage systems into medical oxygen steel cylinders. The filling equipment typically includes filling machines, filling pipelines, and filling control systems.
Oxygen Quality Monitoring System: The oxygen quality monitoring system is used to monitor the quality and purity of oxygen being filled. Quality testing and supervision of the filled oxygen are conducted through an oxygen analyzer or other detection equipment.
Safety Facilities: The filling area should be equipped with corresponding safety facilities, such as fire alarm systems, oxygen leak detection systems, ventilation systems, etc., to ensure the safety and protective measures during the filling process.
It is important to note that the design and equipment configuration of a medical oxygen cylinder filling area must comply with relevant regulations, standards, and specifications. During the filling process, strict adherence to operational procedures and safety requirements is essential to ensure the safe supply of oxygen.
