    Oxygen Diaphragm Compressor Advantages

    Absolutely Oil-Free & Purity Assurance

    The structure of the diaphragm compressor ensures that oxygen is 100% free from contact with any lubricating oil during compression, perfectly complying with the absolute oil prohibition rule for oxygen compression. This prevents violent oxidation reactions and explosion risks while guaranteeing the purity of the outlet oxygen—ideal for medical oxygen generation, high-purity oxygen preparation, and fine chemical processes.

    Zero Leakage Static Seal Safety

    Utilizing static seal structures such as diaphragm isolation and O-rings, zero leakage from the gas side to the environment is achieved. This is crucial for preventing the accumulation of oxygen in the compressor room, which could create an oxygen-enriched environment (concentration >23% significantly increases fire risk), providing the highest level of safety protection.

    Key Design Points for Oxygen Diaphragm Compressors

    Special Material & Degreasing

    All wetted parts (cylinder head, diaphragm, gas valves, piping) must be oxidation-resistant and low-friction, like stainless steel (e.g., 304, 316L) or nickel-based alloys. Thorough degreasing cleaning to remove grease residue is fundamental to prevent auto-ignition incidents.

    Safety Monitoring & Redundancy

    A three-layer diaphragm structure integrated with a rupture alarm system triggers a pressure switch upon outer diaphragm damage. This initiates an audible/visual alarm and an interlock shutdown, preventing contamination between oxygen and hydraulic oil.

    Oil Circuit & Cooling System

    The precise hydraulic system ensures stable oil pressure slightly higher than gas pressure. Efficient inter-stage and after-coolers strictly control discharge temperature, preventing excessive heat that could act as an ignition source.

    Frequently Asked Questions
    Why is a 100% oil-free design mandatory for oxygen compressors?
    Oxygen is highly reactive. Under high pressure, any contact with hydrocarbons (like lubricating oil) can cause violent oxidation, leading to ignition or catastrophic explosions. An oil-free design ensures absolute operation safety and gas purity.
    How does the static seal structure prevent leakage?
    By utilizing metallic diaphragm isolation and O-ring configurations, the process gas is completely isolated from the environment and hydraulic systems. This eliminates dynamic seal wear, guaranteeing zero leakage to the ambient room.
    What is the purpose of the three-layer diaphragm monitoring system?
    The three-layer diaphragm features a rupture detection system. If any layer fails, the pressure change in the interstitial space immediately triggers a pressure switch, shutting down the system safely before gas contamination occurs.
    Why is degreasing treatment critical before compressor assembly?
    Even trace residues of grease or processing oils on metal surfaces can act as fuel in an oxygen-rich environment. Comprehensive chemical degreasing ensures all wetted parts are completely clean and safe for oxygen service.
    How does the cooling system contribute to compressor safety?
    Compression generates heat, which accelerates oxidation. Efficient inter-stage and after-coolers keep gas temperatures low, preventing the system from reaching temperatures that could trigger auto-ignition of materials.
    What materials are used for parts contacting the oxygen?
    We use high-grade, oxidation-resistant materials such as 304 or 316L stainless steel, and specialized nickel-based alloys. These materials maintain integrity under high pressure and do not react with high-purity oxygen.
