Common reasons for failure of air compressor to start normally:

　　1. 如果接触器未闭合，主要是由于气压机电原因(1)要检查气压机电电源连接是否正确，电源开关是否闭合，电源熔断器是否熔断，电源电压是否达到额定电压的90%以上。

　　1. If the contactor is not closed, it is mainly due to the pneumatic electromechanical reasons. (1) first, check whether the pneumatic electromechanical power supply is connected correctly, whether the power switch is closed, whether the power fuse is fused, and whether the power voltage reaches more than 90% of the rated voltage.

　　(2)检查空压机机电源压力继电器各部件是否损坏，压力继电器给定值是否合适。

　　(2) Check whether the components of the air compressor power supply pressure relay are damaged and whether the given value of the pressure relay is appropriate.

　　(3)检查空压机温控器温度传感包内的工质是否泄漏，温控器部件是否损坏，温控指示位置是否调整正确。

　　(3) Check whether the working medium in the temperature sensor package of the air compressor temperature controller leaks, whether the components of the temperature controller are damaged, and whether the temperature control indication position is adjusted correctly.

　　二、如果接触器已经关闭，空压机无法启动，很可能是电机故障或空压机机械故障;(1)检查电机接线相序是否正确，用万用表检测电机绕组是否短路或断路。

　　2、 If the contactor has been closed and the air compressor cannot be started, it is likely to be motor fault or air compressor mechanical fault; (1) check whether the motor wiring phase sequence is correct, and use a multimeter to check whether the motor winding is short circuited or open circuited.

　　(2)检查空压机运转部件是否因润滑不足或间隙过小而抱死或卡死。当轴抱持或气缸卡死时，润滑油中的杂质，更换新润滑油，保证油路畅通。

　　(2) Check whether the running parts of air compressor are locked or stuck due to insufficient lubrication or too small clearance. When the shaft is held or the cylinder is stuck, remove the impurities in the lubricating oil, replace the new lubricating oil, and ensure the smooth oil path.
