Hydrogen Compressor
-
01Absolutely Oil-Free & Purity Assurance:
The unique diaphragm chamber design completely physically isolates the process gas from the lubricating oil system, fundamentally eliminating the risk of oil molecule contamination. This perfectly guarantees the quality of high-purity hydrogen for applications such as electronic-grade and fuel-cell-grade hydrogen, with purity consistently stable above 99.999%.
-
02Intrinsically Safe Zero-Leakage Seal:
Utilizing a static seal structure combined with advanced designs like an embedded diaphragm head, it ensures no risk of hydrogen external leakage. Even in the event of a diaphragm rupture, the three-layer diaphragm structure and diaphragm rupture alarm device can detect it immediately and trigger an interlock shutdown, containing the risk at its inception.
-
01Precise Explosion-Proof Rating Matching:
All electrical equipment, including drive motors and control components, must adopt the highest explosion-proof rating applicable to IIC-class hydrogen. A typical configuration is the composite explosion-proof type such as Ex d e mb px II C T4 Gb, ensuring operational safety in explosive atmospheres. The mechanical properties of the flameproof enclosure fastening bolts must meet strict requirements of tensile strength ≥ 800MPa and yield strength ≥ 640MPa.
-
02Material Compatibility & Special Treatment:
All wetted parts must be made of austenitic stainless steel (e.g., 316L), and undergo high-level degreasing, cleaning, and passivation treatment on the surface to prevent hydrogen embrittlement and ensure ultra-high cleanliness. Piping should preferentially use stainless steel seamless pipes conforming to the GB/T 14976 standard.
-
03Multiple Safety Interlocks & Monitoring:
The safety system must be redundantly configured. In addition to the diaphragm rupture alarm, high/low limit alarms and automatic shutdown interlocks must be set for discharge temperature at each stage (set point ≤ 180°C), lubricating oil pressure, cooling water status (flow/temperature), suction pressure, and discharge pressure. The system must integrate hydrogen concentration sensors and interlock with the emergency ventilation system to ensure environmental safety for skid-mounted or indoor installations.

-
01High Pressure & Large Flow Capacity:
The piston structure makes it easier to achieve higher single-stage pressure ratios and larger volumetric flow rates, efficiently meeting the continuous and stable supply demands for high-pressure, large-flow hydrogen in applications such as hydrogen refueling station filling (25MPa) and large chemical plants.
-
02Mature Technology & High Cost-Effectiveness:
Under the premise of achieving oil-free lubrication, piston compressor technology is mature. The initial investment and long-term maintenance costs are more competitive compared to diaphragm compressors of similar specifications, making it a preferred choice for large-scale hydrogen infrastructure.
-
01Oil-Free Lubrication Design & Strict Temperature Control:
The cylinder must use self-lubricating piston rings and packing made from PTFE or carbon fiber composite materials to completely prevent lubricating oil from entering the cylinder. Given the high adiabatic index of hydrogen and significant temperature rise during compression, inter-stage cooling must be enhanced, and the discharge temperature must be strictly controlled below 120°C (for oil-free high-pressure conditions) to prevent material overheating failure or abnormal hydrogen temperature increase.
-
02Nitrogen Buffer Seal & Leakage Control:Targeting hydrogen's high leakage tendency, the piston rod packing system must adopt a nitrogen buffer seal as recommended by the API 618 standard. By injecting pure nitrogen into the packing box, a micro-positive pressure barrier is formed, effectively preventing hydrogen leakage along the piston rod. The mixture of leaked trace hydrogen and nitrogen should be directed to a centralized vent for safe disposal.
-
03System-Level Explosion Protection & Safety Procedures:
The motor explosion-proof rating must also meet Ex d II C T4 or higher requirements. Process-wise, the inlet piping should be equipped with double block and bleed valves and an inert gas purge connection to ensure thorough air displacement with nitrogen before startup. The relief capacity of safety valves must exceed the compressor's safety relief capacity, and discharge points must be routed to a safe area. The control system must integrate multi-parameter interlock shutdown protection, including low suction pressure, high discharge pressure, cooling water failure, and low lube oil pressure.
