China Oxygen Compressor Suppliers - Factory Oil-Free and Corrosion-Resistant for Safe, Pure Compression

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 not only prevents violent oxidation reactions and explosion risks but also guarantees the purity of the outlet oxygen, making it particularly suitable for medical oxygen generation, high-purity oxygen preparation, and fine chemical processes with stringent oil-free requirements.

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 (an oxygen concentration >23% significantly increases fire risk), providing the highest level of safety protection for operators and equipment.

All wetted parts in contact with oxygen, such as the cylinder head, diaphragm, gas valves, and piping, must be made of materials that are oxidation-resistant, low-friction, and do not produce dangerous reactions through incompatibility. Stainless steel (e.g., 304, 316L) or nickel-based alloys are typically selected. Before manufacturing and assembly, all components must undergo thorough degreasing cleaning to remove any grease residue. This is fundamental for preventing auto-ignition incidents.

A three-layer diaphragm structure is adopted, integrated with a diaphragm rupture alarm system. Once an outer diaphragm is damaged, the pressure change in the middle layer immediately triggers a pressure switch, producing an audible and visual alarm and automatically initiating an interlock shutdown. This prevents oxygen from entering the oil system or hydraulic oil from contaminating the gas, forming a critical safety barrier.

The precise hydraulic oil circuit system must ensure stable oil pressure that is always slightly higher than the gas pressure to protect the diaphragm and ensure compression efficiency. Simultaneously, efficient inter-stage coolers and an after-cooler must be configured to strictly control the discharge temperature at each stage, preventing excessive temperature rise of the oxygen that could exacerbate material oxidation risks or become an ignition source. The cooling system typically needs to be equipped with flow and temperature monitoring and interlock protection.
