Reasons for Oil Leakage in Automotive Air Conditioning Compressors?

Here are the reasons for oil leakage in automotive air conditioning compressors: 1. Avoid blockage of the check valve and vent valve: If the check valve or vent valve is blocked, it will cause the temperature inside the housing to rise, filling the entire space with oil vapor. This increases the pressure inside the housing and adds resistance to the piston's movement, leading to increased oil consumption. Additionally, the pressure difference between the inside and outside of the housing can often cause oil leakage at weak sealing points. 2. Ensure the sealing of various oil pipe joints: The connecting pipe nuts used in engineering machinery are frequently disassembled and reassembled, making them prone to loosening due to stripped threads or broken fasteners. Poor precision in the flare of the two joints, misalignment of the conical surfaces' centerlines, or different cone angles can all lead to oil seepage. The conical sealing surfaces can be repaired by lapping to ensure the nuts are tightly fastened and reliably sealed.

What to Do If Your Car Breaks Down on the Highway?

If your car breaks down on the highway, follow these steps to resolve the issue: 1. Exit the vehicle: Immediately turn on your hazard lights to alert other drivers of the situation. If the car is still operable, move it to the emergency lane and place a warning triangle 150 meters behind the vehicle. All passengers must leave the car and move to a safe area beyond the guardrail to avoid secondary collisions from oncoming traffic. 2. Call for help: Once in a safe location, call the police or emergency services as soon as possible by dialing 110 or 112, or any other emergency number, and wait patiently for assistance. 3. Towing: Do not attempt to tow the vehicle with another car, as this is extremely dangerous and illegal on highways, and may result in penalties. Always wait for traffic police to handle the towing, as they will ensure safety by managing the scene and protecting other vehicles on the road.
