What is the basis for the design of the air compressor outlet buffer tank?
Thread Content
I am responsible for installing equipment in the company; I have installed air compressors several times, and each of them comes with an air outlet buffer tank (air storage tank). I have always been curious about how the volume and dimensions of such tanks are determined – what are the criteria used? I would like to ask my colleagues for advice
The size of the buffer tank in a piston-type compressor is related to factors such as the volume of the cylinder, the properties of the gas being compressed, the timing of air intake and exhaust, and the rotation speed of the crankshaft; generally, it is provided by the manufacturer.
It is generally 20 to 35 times the cylinder volume. Many books provide detailed calculation methods.
Take a look at the instrument air supply specifications; they contain information on volume calculation. The main basis for determining the volume is the gas consumption and the buffering time.
