螺杆空压机在冶金、机械制造、矿山、电力、纺织、石化及轻纺等行业有广泛的应用、是许多工艺流程的核心设备,其装机容量一般取决于生产所需的最大气量并另外增加10%~20%的余量。由于生产中用气量的不均衡,当气体压力达到一定值时,空压机一般采用卸荷空载运行或者停止空气压缩机这两种方式。其中卸荷空载运行时的 Screw air compressors are widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical and light textile industries. They are the core equipment of many technological processes. The installed capacity of screw air compressors generally depends on the maximum air volume required for production and is additionally increased 10% ~ 20% margin. Due to the unbalanced gas consumption in production, when the gas pressure reaches a certain value, the air compressor generally adopts unloaded or no-load operation or stops the air compressor in both ways. Which unloading unloaded operation
