What are the symptoms of air leakage in a compressor piston?
The most direct effect is a decrease in export pressure
The displacement decreases and the inlet temperature rises
I think the main issue is that the compression ratio has decreased
The displacement decreases, the inlet temperature rises, the compression ratio falls, and seal wear intensifies.
The piston temperature will rise significantly; the temperature of the component where there is a leak will increase, and the volume of air flow will drop markedly
The intake pressure increases, the exhaust pressure decreases, the intake temperature rises, and there are noises and backflow sounds in the cylinder.
Piston leakage is mainly manifested in the inability of the highly compressed, high-temperature and high-pressure gas to be expelled; in other words, the volume of exhaust gas decreases. During inhalation, the expansion of this high-temperature and high-pressure gas within the cylinder results in less gas being drawn in, which leads to an increase in the exhaust pressure and temperature in the previous stage.
The displacement is small, so the exhaust pressure at the previous stage increases and the temperature rises; however, the exhaust pressure should remain unchanged
