air conditioning compressor introduce

On the lower right corner of the engine belt, below the generator. The car air conditioning compressor is installed on the engine, and the belt drives the car air conditioning compressor to work together with the engine. You can find the specific location of the car air conditioning compressor by looking for the belt. The following is an introduction to the car air conditioning compressor: 1. The car air conditioning compressor is the heart of the car air conditioning refrigeration system, The compressor plays a role in compressing and transporting refrigerant vapor. There are two types of compressors: constant displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. 2. In the entire system, the compressor is responsible for compressing and driving the refrigerant. Under the drive of the engine, it continuously sucks in the low-temperature and low-pressure refrigerant vapor generated by the heat absorption and vaporization in the evaporator, which is compressed to form high-temperature and high-pressure refrigerant vapor, Discharged into the condenser, it creates high-pressure conditions for the refrigerant to continuously condense and release heat in the condenser. At the same time, it overcomes the circulating flow resistance of the refrigerant in the refrigeration circuit. Helps the automotive parts platform to provide ordering services for original parts of air conditioning compressors for various vehicle models)

Steps for disassembling and assembling automotive air compressors:

Steps for disassembling and assembling a car air compressor: 1. Disassembly sequence of the compressor: Disconnect the power supply, discharge the refrigerant from the compressor, remove the high-pressure and low-pressure pipes respectively, and seal the nozzles of the high-pressure and low-pressure pipes to prevent foreign objects or air from entering. Disconnect the wires of the electromagnetic clutch. Use a special tool to loosen the fixing bolts of the compressor, remove the triangular belt, and the compressor can be removed. 2. Installation sequence of the compressor: When installing the compressor, It should be noted that the groove surfaces of the clutch pulley and the engine pulley are corresponding and on the same plane. The gap between the condenser and the fan should not be less than 20 millimeters, and the standard gap between the compressor, compressor seat, and hose is 15 millimeters. To prevent refrigerant leakage, please replace the O-ring when installing the high-pressure and low-pressure pipes of the compressor. Tighten all fasteners with the specified tools and torque. Finally, Check for leaks in the engine fuel supply system and cooling system

Audi A4L introduce

The Audi A4L is an entry-level luxury B-class sedan produced by FAW Audi. The characteristics of this car are its atmospheric and stable body, meticulous workmanship, solid materials, rich configuration, spacious space, and good handling A4L was officially released on November 16, 2008, and the front face design of the new Audi A4L continues to use the family's expensive sports car design style. The price range of Audi A4L is 272800-578100. The domestic version of the new generation Audi A4 was officially named: Audi A4L. Audi A4L is a new car that Audi only launched in the Chinese Mainland market. The relationship between the new car and A6 and A6L is similar, and it is also after foreign models are made in mainland China, A model derived from changes in configuration and market demand. After higher level mid to high end luxury cars have chosen to be lengthened in China and received good market feedback, this idea is now extending to its lower level mid size car market. Compared with the European version of the Audi A4, the domestic version of the Audi A4L has lengthened the body length by 60mm, reaching 4763mm, and the wheelbase has been lengthened by 61mm, reaching 2869mm, Satisfying the higher requirements of Chinese users for rear passenger space
