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

Buick Excelle XT introduce

The Buick Excelle XT is more fashionable and sporty, with a focus on home use. The Buick Excelle XT's stylish two box sporty appearance is loved by many young people, while the Buick Excelle GT is a three box car that leans more towards home use from the inside out and is no longer as flamboyant. It can be said that the launch of the Excelle GT has expanded the audience of the Excelle series trains. The overall design of the Excelle GT three box car is more oriented towards home use, with a more stable appearance compared to two boxes. From the perspective of appearance, The GT tends to be the popular mid size Buick LaCrosse, also known as the "Little LaCrosse". The Excelle XT is generally more sporty, and from the front face, there is a certain difference between the two cars. The front of the Excelle GT is more rounded and thick, while the Excelle XT has a "steel cannon temperament", full of fashion and sportiness. The headlight design of the Excelle GT is more regular than that of the XT, and the eyes are not as sharp as the XT. The bright and lively upward sloping headlights integrate the width indicator lights, low beam lights, high beam lights, and corner turning lights, The large three shield emblem is embedded on the wide waterfall style air intake grille. The Yinglang GT has two additional gill shaped heat sinks on the engine compartment cover, adding some embellishments to the engine compartment cover. The Yinglang GT has a smooth side shape, which is very in line with people's aesthetic of family cars. After adding one more compartment, the body proportions are still coordinated The shape of the triangular window on the C-pillar has slightly changed compared to the XT. Compared to the Excelle hatchback XT, the roof of the Excelle GT is more protruding, so the rear headroom will be more comfortable
