Intake process: When the compressor starts, the motor drives the crankshaft to rotate, and the piston reciprocates in the cylinder through the connecting rod and the crosshead. The piston moves from the inner dead point of the cylinder to the outer side. At this time, a low-pressure area is formed inside and outside the cylinder, and the gas enters the cylinder through the intake valve.
Compression process: The piston continues to move from the outside to the inside, the intake valve is closed, the gas in the cylinder is compressed, and the pressure increases. When the pressure exceeds the external air pressure of the exhaust valve, the exhaust valve opens and begins to discharge the compressed gas.
Exhaust process: The piston moves from the inside to the outside, the exhaust valve opens, and the gas in the cylinder is discharged. When the piston reaches the outer dead point, the exhaust process ends and a working cycle is completed.
Repeated cycle: The inside and outside of the piston work at the same time, the outside takes in air, and the inside compresses and exhausts air, forming a continuous gas compression cycle.
In addition, modern micro CNG compressors also use many advanced technologies to improve efficiency and reliability, such as:
Double-acting design: allows the inner and outer sides of the piston to simultaneously intake and compress.
Double-gauge seal intermediate: Enhanced sealing performance.
Corrosion-resistant valve plate: Reduced noise and power consumption.
These technologies have significantly improved the efficiency and reliability of micro CNG compressors.
