The mechanical core of air conditioning pump
The mechanical core of air conditioning pump
The most important structure of air conditioning pump is the compressor internal structure, high silicon aluminum alloy on the inclined plate pressure into the shaft become an organic whole, in the aluminum alloy cylinder block before and after, and by the needle roller bearing and the end bearing, piston with two hemispheres slipper on swash plate, in the circumferential direction on the five piston arrangement in the cylinder body and corners equably into 72 degrees.Decorate in the cylinder body, on the face of before and after a suction valve plate of valve slice, the aluminum alloy material, and composed of exhaust valve slice limiter assembly, set up in aluminium alloy cylinder head before and after the annular exhaust and suction cavity, respectively with the passage of the air intake on cylinder body and the exhaust passage connected to it in the middle of the block before and after the top into the vent connected to the refrigeration system.Air conditioning pump seal and shaft seal device ensures the compressor seal, clutch through key connected to the spindle, the coil and the pulley installed on the cylinder head before, pulley through a belt driven by the engine crankshaft pulley. When after connecting a compressor, due to the effect of coil, pulley sucked into rotation together, the clutch to drive the spindle rotating, inclined plate on the rotating pendulum motion, then make on the inclined plate piston reciprocating motion.The five pistons are reciprocating, and each of them has air intake and exhaust respectively, thus becoming a two-way 10-cylinder compressor.Compressor is an important part in the refrigeration system, the compression and transmission of refrigerant gas, which produces in the evaporator refrigerant gas, into the compressor cooling after compression to the condenser.Refrigerant gas from the cylinder block before and after the air inlet into the compressor, respectively before and after entering the ring suction cavity on the cylinder head, due to the movement of the piston, open the suction valve slice of steam inhalation of smoke, and then through the exhaust valve piece into the annular exhaust cavity on the cylinder head before and after, again through the vent on the cylinder body before and after discharge.The lubrication of compressor moving parts is carried out in two ways, one is the refrigerant itself is oily and self-lubricating;The second is splash lubrication.In the audi 100 refrigeration system, the total amount of oil is 300ML, the compressor is only 80ML, the oil in the compressor is stored in the pit in the lower part of the cylinder body, and the other 220ML is added in the liquid separator.In compression work, the freezing oil in the pit is splattered all over the place due to the rotation of the inclined disk.In addition, since the refrigerant and oil have a completely mutually soluble property, the refrigerant is carried into the compressor, which also carries part of the frozen oil to lubricate the moving parts in the compressor.
