diaphragm compressor for rare gas charging in chemical plant

Diaphragm compressors are essential for the compression, transportation, and storage of gases requiring the highest purity. Their unique design avoids any contact between the gas and lubricant, ensuring gas purity up to 99.999%. These compressors excel in handling rare, toxic, corrosive, flammable, or radioactive gases, making them vital equipment across numerous industrial sectors.

Diaphragm Compressor Features

1. High purity gas compression: Gas is completely isolated from lubricating oil and mechanical parts, maintaining ultra-high purity (up to 99.999%).
2. No pollution and no leakage: The diaphragm design isolates gas from the mechanical system, eliminating leakage risks and ensuring contamination-free gas delivery.
3. High compression ratio: Capable of multi-stage compression, diaphragm compressors provide reliable performance across a wide range of pressures, especially at high pressure.
4. Adaptable: Customizable for different pressures and flow rates, suitable for harsh and demanding environments.
5. High safety: Designed for safe operation when handling corrosive, flammable, explosive, or toxic gases.
6. Wide model selection: Available in H, D, L, V, Z and other types, covering needs from low-pressure to ultra-high pressure, single-stage to multi-stage designs.

Working Principle of Diaphragm Compressors

Diaphragm compressors achieve gas compression through a diaphragm-driven reciprocating motion, separating the gas chamber from the drive chamber:

1. Diaphragm movement: A piston or hydraulic system drives the diaphragm to reciprocate within the compression chamber, compressing and discharging the gas.
2. Gas suction and discharge: Gas enters the chamber through a suction valve and is discharged through an exhaust valve after compression.
3. Multi-stage compression: Some models use sequential multi-stage compression for higher efficiency and lower heat generation.
4. Gas isolation: The diaphragm prevents any contact between the gas and lubricating oil or mechanical parts, ensuring pure, uncontaminated gas delivery.
5. Cooling system: An efficient cooling system dissipates heat generated during compression, supporting stable, long-term operation.
