问：我的交流压缩机每7个驱动器中只能工作1个。通常仅在早晨。继电器和其他一切都很好。

听起来您可能会损坏AC压缩机或压缩机离合器。如您所知，AC离合器是带皮带旋转的皮带轮。压缩机后部有两个端口。一个是吸气端口，另一个是排放端口。吸气端口将是您的较大端口，并且排放端口将是较小的端口。将制冷剂吸入吸入端口，压缩，然后退出排放端口，然后进入A/C冷凝器。您的车辆的AC离合器由轮毂，皮带轮和线圈组成。A/C离合器的前部是集线器。接下来是皮带轮，这是皮带骑的地方。最后，在皮带轮下是线圈，也称为磁场线圈。 The Coil is a copper would wire, that functions like a magnetic coil. If the AC Compressor is powered up, electricity engages the coil, and when this happens, it also engages the pulley. The large magnet forces the hub to pull against the pulley. Since the Shaft of the AC Compressor is mated with the A/C Hub, once engaged, it begins to pump refrigerant in the system. Turning whenever the engine is cranked, the A/C Compressor Clutch Pulley will spin even if the AC Compressor is off. If the A/C System is turned on, power is sent to your A/C Compressor Clutch and it will then engage. However, if the pressure in the system (or the refrigerant level) is either too low or high, switches will kill power to the Compressor to keep from damaging it. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.
