The air conditioning compressor is the heart of the air conditioner. Due to the operation of the day and night, the oil film in the air conditioner compressor is damaged, and the refrigerant oil loses lubrication. During the winter, when the air conditioning is heating, the compressor doesn't start and the axle holding phenomenon often occurs. First, the working principle of the air conditioning compressor is introduced.
When the rotor shaft 2 of the compressor is rotated by the spindle of the engine, the blade 3 slips along the slot on the shaft due to the centrifugal force and the oil pressure. Because the cylinder body 1 is elliptical, when the shaft of the compressor rotates, the crescent cavity described by the cylinder block 1, the rotor shaft 2 and the blade 3 will expand, shrink, expand and shrink again and again, so as to achieve the function of suction, compression and exhaust of the compressor. The rotary vane compressor has compact structure, and its volume and weight are only 1/2 of the same specifications of the swashplate compressor. Its torque change is small, its starting performance is good, material saving and energy saving and reliability are high. The refrigerant is cleaner R134a.
