螺杆空气压缩机系统的最全选型方案
The most complete selection scheme of screw air compressor system
1）、选型以“以需定型”结合客户的需要，找到最佳的运行经济性，将来扩大规模均需要作出大量的决策。决策的基础是压缩空气的用途或使用流程，着眼点计算空气需求量，储备量和将来扩展的余地，而压力是一决定因素，对能耗有很大影响，不同的压力范围用不同的压缩机有时可能是经济性。
1) The model selection is based on the needs of customers to find the best operation economy. A lot of decisions need to be made to expand the scale in the future. The basis of decision-making is the use or use process of compressed air, focusing on the calculation of air demand, reserve and room for future expansion. Pressure is a decisive factor and has a great impact on energy consumption. It may be economical to use different compressors in different pressure ranges.
2）、工作压力的计算
2) Calculation of working pressure
压缩空气的设备决定了必须的工作压力取决于压聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 缩机，设备、管路,最高的工作压力决定必须的装置压力，而耗气地点用减压阀来满足设备需求，在极端情况下，配一台单独空压机很不经济。
The equipment of compressed air determines the necessary working pressure, which depends on the compressor, equipment and pipeline. The highest working pressure determines the necessary device pressure, and the pressure reducing valve is used to meet the equipment demand at the place of gas consumption. In extreme cases, it is not economical to equip a separate air compressor.
