What is the problem with the high-pressure gauge shaking?
1 Answers
When the high-pressure gauge of a car's air conditioning system shakes, it is usually due to internal issues with the compressor. Common causes include problems with the one-way valve plate, hydraulic shock, or rapid refrigerant charging. Replacement is often the only solution to eliminate the issue. Another possible reason is unstable high-pressure output from the compressor. You can use an air conditioning pressure gauge to check if the high-pressure gauge is fluctuating. If it is, the compressor is likely damaged. Here is some additional information: Air compressor: In car air conditioning systems, the air compressor is mainly used to regulate its start-stop state. By adjusting the pressure in the air storage tank, the air compressor can be stopped for rest, which helps maintain the machine. During factory debugging of the air compressor, the pressure is adjusted to the specified level based on customer requirements, and a pressure difference is set.
