When the user is ready to purchase an air compressor, he must first determine the work pressure required for the air end, plus a 1-2 bar margin, and then select the pressure of the air compressor. (The margin is considered to be the pressure loss from the installation site of the compressor to the actual gas end pipeline distance, taking due account of the pressure margin between 1-2 bar depending on the length of the distance). Of course, the size of the pipeline diameter and the number of turning points are also factors that affect the pressure loss. The larger the pipeline diameter and the smaller the turning point, the smaller the pressure loss. On the contrary, the greater the pressure loss.

Therefore, when the distance between the air compressor and the gas end pipeline is too far, the main pipe diameter should be appropriately enlarged. If the environmental conditions meet the installation requirements of the air compressor and the working conditions allow, it can be installed near the end of the gas.

Volume flow type selection:

When selecting the volume flow of the compressor, you should first understand the volume flow of all gas equipment and multiply the total amount of flow by 1.2(that is, magnify the 20 % margin)

2, the new project Shangmake according to the flow value provided by the design Institute to select;

3, to use the gas equipment supplier to understand the gas equipment volume flow parameters for selection;

4, the reconstruction of air compressor station can refer to the original parameter value combined with the actual use of gas to select the type;

Proper type selection is beneficial to the user itself and the air compressor equipment. The choice of type is too wasteful, and the selection is too small and may cause the air compressor to be in a loading state for a long time or not enough gas or pressure.

The relationship between power and work pressure and volume flow:

In the case of constant power, when the speed changes, the volume flow and the working pressure also change accordingly; For example: a 22KW empty machine, at the time of manufacture, the working pressure is determined to be 7bar, and the rotation speed is calculated according to the technical curve of the air compressor host, and the displacement is 3.8 m3/min; When the working pressure is determined to be 8 bar, the speed must be reduced(otherwise the driving power will be overloaded). At this time, the displacement is 3.6 m3/min; Because the speed is reduced, the exhaust gas is reduced accordingly, and so on.

The power selection is to meet the working pressure and volumetric flow conditions, the power supply capacity can meet the matching driving motor use power can be.

Therefore, the step of selecting an air compressor is to first determine the working pressure, then determine the corresponding volume flow, and finally the power supply capacity.
