When selecting liquid oxygen storage tanks with medical oxygen generators, several factors should be considered:
Requirement: First, determine the oxygen demand of the institution or individual. Select the appropriate oxygen concentrator model and specification based on the required oxygen flow rate and pressure.
Safety and Reliability: Ensure the selected oxygen concentrator offers high levels of safety and reliability. Choose products that comply with relevant standards and regulations, featuring safety functions such as overpressure protection, leakage protection, and overload protection.
Ease of operation: Choose an oxygenator with simple and user-friendly operation. Consider the methods for adjusting oxygen flow and concentration, as well as the clarity and readability of the operating interface.
Quality and Reputation: Choose oxygen concentrators with good quality and reliability. Refer to user reviews, word-of-mouth, and certifications when selecting products.
Maintenance & After-Sales Service: Understand the maintenance requirements and after-sales support for the oxygenator. Ensure timely access to repairs and technical assistance to ensure the normal operation and maintenance of the oxygenator.
Cost-Effectiveness: Choose a product with a good price-performance ratio by considering the price, performance, and functions of the oxygenator. Select the appropriate oxygenator based on actual needs and budget.
Note that when selecting a liquid oxygen tank with a medical oxygen generator, it's essential to adhere to the relevant equipment procurement regulations and standards. It's advisable to consult with equipment suppliers or relevant institutions to ensure the oxygen generator meets your requirements and safety standards.

During the installation of the central oxygen supply low-temperature liquid oxygen storage tank, particular attention should be given to the following aspects:
Safe Operation: Strict adherence to safety procedures and standards is mandatory during the storage tank installation process. Operators must be trained, familiar with the properties and safety requirements of liquid oxygen, and knowledgeable about the equipment and operational procedures to ensure safe operations.
Fire Prevention Measures: Liquid oxygen contains a high concentration of oxygen, which is prone to cause fires. During the installation process, necessary fire prevention measures should be taken, such as setting up fire barriers, using fire-resistant coatings, and prohibiting open flames, to prevent the occurrence and spread of fires.
Leakage Control: Pay attention to leakage control during the installation process. Oxygen leakage can lead to increased oxygen concentration, heightening the risk of fire and explosion. Equip with leak detection and alarm systems to promptly identify and control leaks, and take appropriate emergency measures.
Oxygen Concentration Monitoring: During the installation process, the oxygen concentration around the liquid oxygen storage tank should be monitored regularly. High oxygen concentrations can intensify the combustion of flammable substances, increasing the risk of fire and explosion. Take timely measures to ensure the oxygen concentration remains within safe limits.
Grounding and Static Dissipation: During the liquid oxygen facility process, ensure proper grounding of storage tanks and related equipment to minimize static buildup and discharge. Utilize static-conductive materials and anti-static equipment to reduce the dangers caused by static discharge.
Regular inspections and maintenance: After installation, the liquid oxygen tank should be regularly inspected and maintained. This includes visual inspections, pressure tests, leak detection, etc., to ensure the tank's safety and stability.
Note that during the installation of central oxygen supply low-temperature liquid oxygen storage tanks, the operation should be performed by experienced personnel and follow relevant safety operation procedures and standards. Close attention should be paid to safety risks throughout the installation process, and timely measures should be taken to ensure the safety and stability of the installation.

Maintenance and care 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 exterior, internal structure, and anti-corrosion coating inspections. Check for cracks, corrosion, wear, and other issues, and identify and repair potential safety hazards in a timely manner.
Cleaning and Deicing: Regularly clean the external surface and internal structure of low-temperature storage tanks to remove accumulated dirt and ice layers. Ice buildup can lead to structural damage and corrosion; cleaning and deicing 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 insufficient levels can lead to overpressure or over-vacuum in the tank, increasing safety risks.
Leak Detection: Install a leak detection system to regularly check for leaks in low-temperature storage tanks. Leaks can cause the escape 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 system 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 operators and maintenance staff to ensure they have the relevant knowledge and skills to properly operate and maintain low-temperature storage tanks.
It's important to note that maintenance and upkeep should be tailored to the specific type of tank and usage conditions, adhering to relevant local regulations, standards, and norms. During the maintenance process, it is advisable to consult with engineers or guidance from relevant institutions to ensure the tank's safety and reliability.

Routine inspections of liquid nitrogen tanks should include the following aspects:
Level Inspection: Regularly check the liquid nitrogen tank's level to ensure it is within the normal range. This can be done using a level gauge or a level scale, among other equipment.
Pressure Check: Inspect the tank's pressure to ensure it remains within the safe range. Devices such as pressure gauges or pressure sensors can be used for the check.
Insulation Layer Inspection: Verify that the storage tank's insulation layer is intact, without any damage or detachment. The integrity of the insulation layer is crucial for reducing heat transfer and the evaporation of liquid nitrogen.
Leak Inspection: Check for signs of liquid nitrogen leakage around the storage tank, such as vapor mist, frost, or freezing. If a leak is detected, take immediate action to repair it.
Valve and pipeline inspection: Verify that the valves and pipelines of the storage tank are functioning properly without any gas leaks or blockages. Ensure the tightness and unobstructed flow of the valves and pipelines.
Safety Device Inspection: Check the storage tank's safety devices, such as pressure relief valves, temperature sensors, and level alarms, to ensure they are functioning properly.
Tank exterior cleaning: Regularly clean the external surface of the tank to remove dust, dirt, and debris. Maintain the tank's appearance for easy inspection and maintenance.
Tank Records and Documents: Timely record the inspection results and maintenance records of the tank, including liquid level, pressure, insulation condition, and leakage status. These records aid in monitoring the tank's operational status and promptly identifying issues.
The above details the routine inspection points for liquid nitrogen storage tanks. Regularly performing these checks ensures the safe and efficient operation of the tank. Additionally, adhere to relevant safety regulations and operational guidelines to ensure the safety of personnel and equipment.
