Discover the Structure, Benefits, and Our Proven GZ-500/16-29 Model
In the hydrogen energy industry, where gas purity, leak-free performance, and explosion-proof safety are paramount, diaphragm compressors have emerged as the most trusted technology for high-pressure gas handling.
But how exactly does a diaphragm compressor work? What makes it better than other types of compressors for hydrogen applications?
Let’s break it down—with real data from our GZ-500/16-29 model, already used in global hydrogen projects.
⚙️ ダイアフラム・コンプレッサーの仕組み
A diaphragm compressor compresses gas using flexible metal diaphragms rather than pistons. The diaphragm is hydraulically actuated—moved back and forth by a plunger that is powered by a crankshaft and motor. Gas is compressed in a completely sealed chamber, never coming into contact with oil or lubricants.
This makes it the ideal choice for ultra-pure, flammable, or toxic gases, such as hydrogen.
🔩 Main Components of a Diaphragm Compressor
Gas-end chamber: The area where hydrogen is compressed—100% leak-tight and oil-free.
Metal diaphragm (usually stainless steel): Provides flexible movement to compress the gas.
Hydraulic oil system: Drives the diaphragm with consistent force.
Crankshaft and motor drive system: Converts electric motor energy into reciprocating motion.
Cooling system: Often water-cooled to maintain stable temperature under high pressure.
Safety valves and sensors: Prevent overpressure and ensure system integrity.
All components are housed in a compact, explosion-proof frame, with customizable features depending on application needs.
