Excavator compressors typically employ a reciprocating or rotary structure. Their core function is to increase low-pressure gas to high-pressure gas, providing power to the excavator. The specific process is as follows:
1. Intake Process: When the compressor is in intake mode, low-pressure gas is drawn into the cylinder through the intake valve.
2. Compression Process: As the piston moves upward, the gas volume inside the cylinder gradually decreases, the gas is compressed, and the pressure and temperature gradually increase.
3. Exhaust Process: When the piston reaches top dead center, the high-pressure gas is discharged through the exhaust valve, providing power to the excavator.
