空压机过热故障现象:空压机排气温度过高。松压阀或卸荷阀不工作导致空压机过热故障。气制动系统泄露严重导致空压机过热故障。运转部位供油不足及拉缸。
空压机过热故障判断与排除方法:进气卸荷时检查松压阀组件,有卡滞的清洗排除或更换失效件。排气卸荷时检查卸荷阀有堵塞或卡滞的要清洗修复或更换失效件,有效排除空压机过热故障;检查制动系统件和管路;活塞与缸套之间润滑不良、间隙过小或拉缸均可导致过热,遇该情况应检查、修复或更换失效件。
在日常使用空压机的过程中,空压机经常会出现异响,例如:金属撞击声,均匀的敲击声,摩擦啸叫声的空压机异响故障。

空压机异响故障原因:连杆瓦磨损严重,连杆螺栓松动,连杆衬套磨损严重,主轴磨损严重或损坏产生撞击声;皮带过松,主、被动皮带槽型不符造成打滑产生空压机异响;空压机运行后没有立即供油,金属干摩擦产生空压机异响;固定螺栓松动;紧固齿轮螺母松动,造成齿隙过大产生空压机异响敲击声;活塞顶有异物。
空压机异响故障判断与排除方法:空压机一响时,检查连杆瓦、连杆衬套、主轴瓦是否磨损、拉伤或烧损,连杆螺栓是否松动,检查空压机主油道是否畅通;建议更换磨损严重或拉伤的轴瓦、衬套、主轴瓦,拧紧连杆螺栓,用压缩空油孔对准空压机进油孔;气疏通主油道。重新装配时,应注意主轴轴承。

空压机一响时,检查主、被动皮带轮槽型是否一致,不一致请更换,并调整皮带松紧度。
检查润滑油进有压力、机油管路是否破损、堵塞,压力不足应立即调整、清理、更换失效管路;检查润滑油的油质及杂质含量,与使用标准比较,应立即更换;检查空压机是否供油,若无供油应立即进行检查。
