Purchase method:
When preparing to buy an air compressor, you must first determine the required working pressure at the air end, plus the margin of 1-2 bar, and then select the pressure of the air compressor (the margin is the pressure loss from the installation position of the air compressor to the actual air end pipeline, and the pressure margin should be properly considered between 1-2 bar according to the length of the distance).
Of course, the diameter of the pipeline and the number of turns are also factors that affect the pressure loss. The larger the pipe diameter, the fewer turning points and the smaller the pressure loss. Conversely, the greater the pressure loss.
Therefore, when the distance between the air compressor and each gas end pipeline is too far, the diameter of the main pipeline should be appropriately increased. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed at the gas end nearby.
