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

BMW 328Li introduce

The BMW 328Li has no significant configuration differences in the front part of the car. The hood extends in a wedge-shaped shape from the upper edge of the headlights to the lower edge of the front windshield, and the multi edged design makes the new hood look more dynamic. The enlarged front grille is a prominent feature of this generation of 3 Series, and the new headlight group closely connected to the grille is more aggressive. The chrome plated decorative strip in the fog light area, which is unique to the new 3 Series, is firmly covered by black tape, But the overall lines are clearly exposed. The side of the BMW 328Li can be clearly seen to be different from the overseas version of the 3 Series. The size of the rear door has a more obvious increase, and the line at the back of the side skirt tends to be more straight. This also means that it will be an authentic domestic new 3 Series sedan, which will provide more abundant rear seating space for Chinese consumers. The BMW 328Li will be equipped with a brand new 4-cylinder turbocharged engine, The maximum power is 240 horsepower, matched with a brand new 8-speed automatic transmission. The first six gears of the new transmission adopt a 1:1 gear ratio, and the last two gears are super ratio gears, which can help reduce fuel consumption during high-speed cruising
