Compressed air tanks they are important devices for every compressed air system and are available in various sizes and shapes. In this article, let’s explore the importance, function, structure, and other relevant knowledge related to compressed air tanks together with VIVA.

What is a compressed air tank?

A compressed air tank (also known as an air receiver tank) is a device used to store and supply high-pressure compressed air for a compressed air system. It is used in various applications, including industrial, automotive, medical, electronics, and more.

Due to the nature of the work, compressed air tanks are constructed from materials capable of withstanding high pressure, such as commonly used steel, aluminum, or stainless steel. The volume of a compressed air tank depends on the scale of the compressed air system and can range from a few liters to thousands of liters (7 liters, 10 liters, 20 liters, etc.).

Air from the environment is compressed at high pressure through an air compressor and then stored inside the compressed air tank. The compressed air from the tank is then used to operate the compressed air system.

When compressed air is needed, the tank supplies compressed air pressure to the system through valves and connecting pipes. The pressure in the tank gradually decreases as compressed air is used, and when the pressure reaches a certain level, the tank is refilled with compressed air from the air compressor.

A compressed air tank is an integral part of a compressed air system, allowing for storage and supply of high pressure when needed.

Note that a compressed air tank is different from a hydraulic accumulator or a water storage tank, even though they all serve the purpose of storing high-pressure fluids. Due to the different properties of compressed air, water, and hydraulic oil, the tanks used for these different fluids have distinct designs.

Structure and Operation of Compressed Air Receiver Tank

The structure and operation of a compressed air receiver tank, which is a topic of great interest, have been provided to our customers during the product consultation process. Understanding the structure and operation of the air receiver tank helps customers utilize the equipment more efficiently while ensuring the maintenance of the equipment and system is performed correctly and safely. Now, let’s explore the structure and operation of the compressed air receiver tank with VIVA.

Structure

Depending on the type and manufacturing unit of the compressed air tank, there may be some minor differences between them. However, the basic structure of the devices remains the same, and they consist of the following main components:

  • Tank body: The tank body is made of high-pressure-resistant materials, mostly carbon steel, and is coated with epoxy paint to protect the surface and ensure safety. Some tanks are designed to work in corrosive environments and use stainless steel instead. The shape of the compressed air receiver tank is either cylindrical or spherical, aiming to distribute stress.
  • Inlet and outlet valves: The compressed air receiver tank has two important valves. The inlet valve is used to fill the tank with compressed air from an external supply, while the outlet valve is used to release the air pressure from the tank when necessary.
  • Safety valve: This device is commonly known as a compressed air safety valve, which was mentioned in a previous article. The valve is installed on the body of the compressed air receiver tank and has the function of automatically releasing compressed air into the environment in case the pressure inside the tank becomes too high (the pressure release level can be adjusted).
  • Pressure gauge: The tank usually comes with a pressure gauge to monitor the internal pressure. This helps the user know the current pressure level inside the tank.
  • Connecting pipes: The compressed air receiver tank has connecting pipes to link the tank with the compressed air system. These pipes allow the compressed air pressure to be delivered from the tank to the devices and machinery that use compressed air.
  • Condensate drain valve: Compressed air in the receiver tank is generated by compressing air from the external environment. Therefore, after a certain working period, moisture in the air, under high pressure and density conditions, will condense and form water inside the compressed air receiver tank. At the bottom of the tank, there is a valve for draining the water outside.

In summary, the compressed air receiver tank has a simple structure consisting of a pressure-resistant tank body, inlet and outlet valves, overflow prevention mechanism, pressure gauge, and connecting pipes. This structure allows the compressed air receiver tank to store and supply compressed air when needed.

Operation

The compressed air receiver tank operates according to the following basic steps:

  • Compressed air filling: Initially, the compressed air receiver tank is filled with compressed air from an external supply. The compressed air from this source is directed into the tank through the inlet valve. When the inlet valve is open, compressed air flows into the tank, increasing the internal pressure. The inlet valve is then closed once the desired pressure is reached (a commonly seen type of inlet valve is a pressure relay).
  • Pressure storage: Once the compressed air receiver tank has been filled, the compressed air is stored within the tank. The pressure-resistant tank body holds the compressed air within its internal space. The stored compressed air in the tank serves as a pressure supply for use by other devices or systems.
  • Pressure supply: When compressed air pressure is required, the outlet valve is opened. When the outlet valve is open, compressed air is released from the tank and flows through the connecting pipes, delivering it to devices or machinery that use compressed air. The pressure inside the tank gradually decreases over time as the compressed air is utilized.
  • Recharging with compressed air: When the pressure inside the tank decreases to a certain level, the compressed air receiver tank needs to be recharged with compressed air from an external supply. This process continues until the tank reaches the desired operating pressure and is ready to provide compressed air pressure to the system when needed.

Note that controlling and managing the pressure within the compressed air receiver tank is crucial to ensure the safety and efficiency of the compressed air system.

Considerations when choosing a compressed air receiver tank

When selecting a compressed air receiver tank, here are some points to consider:

  • Working pressure: Determine the required working pressure for your application. Make sure that the compressed air receiver tank can withstand this pressure and has a safety margin (the pressure limit of the receiver tank should be higher than the regular working pressure of the system).
  • Volume: Consider the air flow requirements and operating time. The volume of the compressed air receiver tank should be large enough to provide compressed air for the desired duration, meeting the continuous operation needs of the system.
  • Material and quality: Choose the material for constructing the compressed air receiver tank based on the working conditions. Carbon steel is a commonly suitable material in most cases. However, in more severe operating conditions, equipment is often made from stainless steel.
  • Size and weight: The size and weight of the compressed air receiver tank are also important factors to consider, especially when installation space is limited. Some receiver tanks are mounted on supports, so the weight of the tank must be within the designed load-bearing capacity.
  • Redundancy and expansion capability: In practical terms, it is not possible to anticipate all situations during the system design phase that may arise in real-world applications. Due to various factors, the pressure level may decrease over time, or additional equipment may be added, increasing the actual power consumption. Therefore, it is important to consider these possibilities during equipment selection and choose a tank with a larger capacity to accommodate future development needs.

The above points are some small considerations that we want to share with our customers and readers. We hope they can assist you to some extent in choosing the appropriate compressed air receiver tank.
