我厂使用的上海英格索兰螺杆空压机，在维修中一项关键的技术是排气端间隙的调整，调整间隙的大小直接影响压缩机的工作性能。间隙过大，会降低压缩机工作效率，造成出气量不足，功率达不到，同时机器本身排温高，造成冷却器负荷加大，外界温度一升高，就会造成机器超温而自动 I Shanghai plant used Ingersoll Rand screw air compressor, a key technology in the maintenance of the exhaust side of the gap adjustment, adjust the size of the gap directly affect the performance of the compressor. Gap is too large, will reduce the compressor efficiency, resulting in insufficient output, the power does not reach the same time, the machine itself, high temperature, resulting in cooler load increases, the external temperature increases, it will cause the machine over-temperature and automatic
