Low Noise VPSA Oxygen Generator with Long Maintenance Cycle and Modular Design for Industrial Use

With molecular sieves as the core separation medium, our VPSA Oxygen Generator efficiently separates oxygen and nitrogen components in the air through the alternation of low-pressure adsorption and vacuum desorption, producing oxygen that meets both industrial and medical standards. Key advantages include:

• Low power consumption (0.32-0.38kWh/Nm³)
• Fast start-up capability
• Simple maintenance requirements
• Modular design for flexible production capacity

Before installing a VPSA Oxygen Generator, ensure the site meets these critical requirements:

• Structural Requirements: Flat, solid surface with floor bearing capacity of 5kN/m² (small units) to 15kN/m² (large systems). Foundation must use C30 concrete with steel plates (≥12mm thickness) for equipment fixation.
• Environmental Conditions: Well-ventilated area (≥3 air changes/hour) with relative humidity ≤85%. Avoid dust sources or install appropriate filtration.
• Space Requirements: Minimum 1.5m clearance from walls/obstacles for maintenance access.

The installation involves three key stages:

• Equipment Positioning: Level adjustment (≤0.5mm/m deviation) and secure anchoring of blower/vacuum pump.
• Pipeline Connection: Use corrosion-resistant stainless steel pipes (304/316L) with 1‰-3‰ slope. PTFE gaskets for airtight seals followed by pressure testing (1.2× working pressure for 30 minutes).
• Electrical Installation: 380V/50Hz three-phase supply with dedicated circuit (≤30mA leakage protection). Grounding resistance ≤4Ω. PLC system integration via Modbus protocol if required.

Daily: Monitor pressure (0.1-0.3MPa) and flow (±5% of rated value). Clean air pre-filter.

Weekly: Inspect seals for leaks (soapy water test). Check blower/vacuum pump oil levels.

Monthly: Calibrate oxygen purity sensor. Test pressure relief valve functionality.

Troubleshooting: For purity below 90%, check filter and molecular sieve condition. Excessive vibration may indicate loose bolts or bearing wear. Molecular sieve replacement typically required every 5-8 years depending on usage intensity.
