high pressure V type differential piston air compressor

The high-pressure V-type differential piston air compressor is designed for stable, high-pressure air supply in a compact footprint. Equipped with a water cooling system and advanced automation, it ensures reliable long-term operation, controllable temperature, and exceptional service life. Its perfect air drying treatment and high compression efficiency make it the ideal choice for demanding scenarios requiring clean, high-pressure gas.

Features of High-Pressure V-Type Differential Piston Air Compressor

1. V-type double-row structure: Optimized cylinder arrangement reduces unit size and increases operational smoothness.
2. Double-acting piston design: Pistons compress air in both directions, increasing air delivery per unit time.
3. Four-stage compression: Multi-stage compression reduces single-stage ratio, lowers power consumption, and increases exhaust pressure.
4. Differential piston technology: Pistons with varying diameters at each level maximize compression efficiency by handling different pressures in a single stroke.
5. Water cooling system: Circulating cooling water effectively reduces temperature during compression, preventing overheating and extending equipment lifespan.
6. Full-automatic control system: Enables pressure adjustment, auto start/stop, and fault alarms for enhanced safety and convenience.
7. Air drying treatment: Efficiently removes moisture, delivering dry, high-quality compressed air for sensitive applications.
8. Work pressure: Up to 40 Mpa.

Principle of Operation

1. First stage: Air enters via inlet valve and is initially compressed by a large-diameter piston, then cooled through an intercooler.
2. Second stage: Cooled air is further compressed by a medium-diameter piston and cooled again.
3. Third stage: Air is compressed by a smaller piston, pressure rises, and cooling reduces temperature.
4. Fourth stage: Final compression with the smallest piston head, followed by after-cooling and air drying before output at 40 Mpa.

Stepwise compression and cooling reduce stress on each cylinder stage, lower energy use, and ensure consistent, high-quality air output.
