At present, the air-conditioning compressor assembly equipped on the Jetta Golf Car is supplied by two manufacturers. Therefore, when the above-mentioned fault occurs, it must be confirmed whether the vehicle is equipped with the following two types of Shanghai Sanpower SD7V16 air-conditioning compressor assembly. The method can be identified. (l) The signboard on the air conditioner compressor produced by Shanghai Sandian on the air conditioner compressor produced by Shanghai Sandian, SD represents Shanghai Sanpower. (2) The air-conditioning compressor assembly produced by Shanghai Sandian has obvious concave and convex shapes in the red circle. 2 electromagnetic clutch selection At present, the air-conditioning compressor assembly produced by Shanghai Sanpower is equipped with two different types of electromagnetic clutches, the part numbers are L357820 sllH and LIJO820sllE respectively. Therefore, when deciding to replace the electromagnetic clutch, the electromagnetic clutch selection method must be correctly selected. There are the following two types. (l) Select the electromagnetic clutch part number L357 82081IH electromagnetic clutch based on the air conditioner compressor assembly part number for the air conditioner compressor assembly on part numbers LIGD820803BLIGD820 803CLIGD820803 and L535820 803; the electromagnetic clutch part number LIJO820sllE is used in Part number is LIJD820803LIJO820 803K and LIJO820803F air conditioning compressor assembly. (2) Select the electromagnetic clutch according to the appearance of the air-conditioner compressor assembly. The power plug of the air-conditioner compressor assembly is a small square plug, and the high-low pressure pipeline connection part is an integrated air-conditioner compressor. The assembly part number is L357820 811.H. The electromagnetic clutch of the air conditioner compressor assembly is an elliptical large plug, and the high and low pressure pipeline connection parts are mutually independent air conditioner compressors, and an electromagnetic clutch of part number LIJO820sllE is required. 3 replacement method and operation precautions When replacing the electromagnetic clutch of the air conditioner compressor, just remove the air conditioner compressor assembly from the fixed bracket (Note: you do not need to disassemble the refrigerant circuit when replacing the electromagnetic clutch of the air conditioner compressor), according to the % Baolai car maintenance manual & heater air conditioning system Remove the electromagnetic clutch assembly in the order specified in 87-55 to 87-8 and replace it. However, pay attention to the following problems during the replacement process. (l) The new electromagnetic clutch assembly spare parts do not include the adjustment gasket under the electromagnetic clutch suction cup. Therefore, do not discard the gasket when disassembling the old electromagnetic clutch. When installing the new electromagnetic clutch assembly, Use the original old adjustment pad. (2) The circlip of the coil pulley must be installed in the correct direction, and confirm that the circlip is completely installed in the circlip groove. (3) The tightening torque of the air conditioner compressor spindle nut is 19N adjoining INm. It must be noted that the tightening torque should not be too large. The adjusting washer under the electromagnetic clutch suction cup is inserted downwards. The direction of the coil pulley is correctly installed. Tighten the compressor spindle nut. (4) When disassembling the clutch disc, special tool 3212 is required. (5) If it is difficult to assemble the air conditioner compressor pulley during the assembly process, the special tool VW 516) can be placed on the inner ring of the bearing and tapped with a plastic hammer. A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.
