Basic introduction of air compressor supporting gas storage tank
Air compressor air storage tank, also known as compressed air storage tank, is a pressure vessel specially used to store compressed air. The function is used for gas storage buffer to avoid frequent loading and unloading of air compressors and removing most of the liquid water. It is mainly used in conjunction with air compressors, freeze dryers, filters and other equipment to form a power source for industrial production- Compressed air station.
A complete air compressor system will definitely include air compressors, air storage tanks, freeze dryers, filters and other equipment, but when installing an air compressor station, whether the air storage tank is installed after the air compressor is installed, or It has been placed after the cold dryer and installed later. There has always been controversy. Most of the design institutes are designed at the later position of the air compressor station, but in the actual installation process, most air compressor manufacturers require the air compressor to come out. The gas storage tank is installed, so it is caused by how to install the air compressor station in the factory.
The air compressor and the air storage tank are used to stabilize the air pressure (the air pressure is very unstable when the air compressor is working; there is a large fluctuation.) The air pressure is controlled in the appropriate range for the equipment to use. From the perspective of energy saving, a pressure storage tank should also be installed to avoid frequent startup of the air compressor. Another is to facilitate automatic control. The air compressor is now equipped with an air pressure control switch to achieve automatic control. If there is no pressure storage tank, it is difficult to control automatically. (Because the air pressure is unstable)
We all know that correct adjustment of your air tank is a key part of keeping compressed air at low cost. So it is very important to choose the right gas storage tank. And you have a gas tank, do you know where to put it?
If you have a smaller, tank-mounted compressor, your gas storage tank is built-in. If your system is large and has separate components, it may be difficult to figure out where your gas tank will be more effective. The gas storage tank has two main locations, each with unique advantages and disadvantages.
Wet gas tank
Some operators install an air storage tank before the compressed air dryer. This is called a "wet air tank" because compressed air is still saturated with water. Passing compressed air through a wet air storage tank can provide some radiant cooling to remove condensate and entrained oil. Because it allows moisture to escape from the air, wet compressors make compressed air dryers easier to work.
As the name suggests, the wet gas storage tank is filled with saturated air. If demand suddenly increases, this may cause problems. If the demand exceeds the compressor and dryer capacity ratings, the dryer may become overloaded. This can result in high pressure dew point or higher water content in the air, which may damage the system or affect the end use.
Dry gas tank
The compressed air enters the dry air storage tank after it has passed through the dryer. Although it does not help the dryer to remove condensation in advance, it does have its own advantages. Any sudden demand can be met with dry air and will not exert unnecessary pressure on the dryer.
So, should operators use wet or dry gas tanks? Why can't we have both? An additional air storage tank does not cost much purchase cost. Putting the air storage tank before or after the dryer allows the operator to benefit from wet air and dry air; placing the wet air storage tank before the dryer can control the capacity and condensation dew point And the second dry gas storage tank can meet the sudden increase demand.
