结冰通常要先看水分和压降 Check moisture and pressure drop first
低温下压缩空气中的水分、管路冷凝、排水状态和快速膨胀降温都可能导致结冰或动作异常。 Moisture in compressed air, hose condensation, drainage and rapid expansion cooling can cause freezing or abnormal movement in cold conditions.
停机后先安全排水检查 Shut down safely before drainage checks
按现场制度停机、断气、卸压，检查空压系统排水、储气罐和管路低点，不能用明火直接烘烤设备或带压部件。 Follow site rules to stop, isolate air and release pressure. Check compressor-system drainage, receivers and hose low points. Never heat equipment or pressurized components with an open flame.
重新启用前确认润滑与动作 Check lubrication and movement before restarting
解冻、排水和外部检查完成后，按对应型号要求确认润滑、连接和空载状态；持续异常应交专业检修。 After thawing, drainage and external checks, follow model-specific requirements for lubrication, connections and no-load condition. Persistent faults require qualified service.
