Work pressure, exhaust pressure selection: when users ready to air compressor unit of choose and buy, the first thing to determine the working pressure of gas side need, add 1 to 2 bar allowance, then choose the pressure of the air compressor, (the allowance is considered from the air compressor installation location to the actual gas pipeline pressure loss of the distance, according to the length of the distance between 1-2 bar pressure due consideration allowance).Of course, the size of pipeline diameter and the number of turning points are also factors affecting pressure loss. The larger the pipeline diameter is and the less the turning point is, the smaller the pressure loss will be.Otherwise, the pressure loss will be greater.Therefore, when the distance between the air compressor and the gas end pipe is too far, the diameter of the main road should be appropriately enlarged.If the environmental conditions meet the requirements of air compressor installation and operating conditions allow, can be installed near the gas end. The selection of volume flow: (1) in the choice of air compressor volume flow, should first understand the volume flow of all gas equipment, the total number of the flow times 1.2 (that is, 20% of the amplification allowance); (2) the new project on the mark according to the flow value provided by the design institute for selection; (3) to use gas equipment suppliers to understand the volume flow parameters of gas equipment for selection; (4) air compressor station transformation can refer to the original parameter value combined with the actual gas situation for selection;Proper selection is beneficial to both the user and the air compressor equipment. Excessive waste of type selection, type selection is too small may cause the air compressor in the state of long-term loading or not enough gas or pressure up and other disadvantages.
