Working Principle of Piston Compressor

When the crankshaft of the piston compressor rotates, the piston reciprocates, creating a change in the working volume formed by the cylinder’s inner wall, cylinder head, and piston top surface. As the piston moves away from the cylinder head, the working volume increases, allowing gas to flow in through the intake pipe. When the working volume reaches its maximum, the intake valve closes. When the piston moves in the opposite direction, the working volume decreases, and the gas pressure increases. Once the pressure in the cylinder exceeds the exhaust pressure, the exhaust valve opens, allowing the gas to be discharged from the cylinder. This cycle repeats with each rotation of the crankshaft, allowing for efficient air intake, compression, and exhaust.

Advantages of Piston Compressor

1. Wide applicable pressure range, ensuring the desired pressure regardless of the flow rate.
2. High thermal efficiency and low unit power consumption, making it energy-efficient.
