氧气增压压缩机：规格指南
工程师和采购经理在指定氧气增压压缩机之前需要了解哪些内容——从技术选择到压力级配置。
什么是氧气增压压缩机？
氧气增压压缩机是一种往复式机械，它将氧气流的压力从较低的入口压力提升到下游工艺或储存系统所需的较高出口压力。气源（通常是变压吸附式制氧机、变压吸附式制氧机或液氧汽化器）已经完成了初始压力提升。增压压缩机利用这些气体进一步提升压力。
最常见的应用是氧气瓶充气站（入口压力 0.1–0.5 MPa，瓶内压力 15.0–16.5 MPa）；炼钢氧气管道（3.0–3.5 MPa）；以及玻璃熔炉的富氧燃烧系统（1.0–1.6 MPa）。
为什么压缩机必须是无油的
压缩氧气与碳氢化合物润滑剂会发生剧烈反应。在压缩气缸内的高压高温环境下，即使少量矿物油也会自燃。无油往复式压缩机完全消除了压缩区的润滑剂——活塞在聚四氟乙烯（PTFE）复合材料的活塞环上运行；气缸壁无需润滑。输出符合 ISO 8573-1 0 级油品要求，无需任何下游过滤器。
Pressure Stage Configuration
Each compression stage should not exceed a ratio of approximately 3.5–4:1. For oxygen (specific heat ratio gamma ≈ 1.4), this limits per-stage temperature rise to below 160°C in normal industrial service.
| 阶段 | Outlet Pressure | Typical Application |
|---|---|---|
| 2-stage | 0.20 – 0.80 兆帕 | PSA distribution, ASU output |
| 3-stage | 3.0 – 3.5 MPa | Steel mill pipeline, BOF converter |
| 4-stage | 10 – 15.0 MPa | Cylinder filling (large capacity) |
| 5-stage | 15.0 – 16.5 兆帕 | Cylinder filling (ZW compact series) |
Inter-stage water-cooled heat exchangers with moisture separators are fitted between every stage on all models above 18.5 kW. Condensate discharge is automatic.
How to Specify an Oxygen Booster Compressor
When enquiring, providing the following information allows us to return a complete technical recommendation:
- Gas type and purity (medical or industrial; trace contaminants)
- Inlet pressure — minimum and maximum (PSA output varies with regeneration cycle)
- Required outlet pressure — steady-state and peak
- Flow rate in Nm³/h or m³/min at inlet conditions (specify clearly)
- Duty cycle: continuous 24-hour, intermittent or seasonal
- Cooling medium: water temperature/pressure or air-cooled preference
- Power supply: voltage, frequency, available fault current
- Installation: indoor/outdoor, altitude, ambient temperature range
- Applicable standards: API 618, local pressure vessel code, area classification
PSA Integration — Key Consideration
A buffer receiver between PSA and booster is strongly recommended. Size the receiver for at least 10–15 minutes of compressor flow capacity. The booster inlet low-pressure cutoff protects the machine if PSA output falls below the minimum safe inlet pressure.
150 bar vs 165 bar & EPC Procurement
Cylinder Filling Pressure Selection
The most common fill pressure for T-type industrial cylinders in Europe and Asia is 150 bar (15.0 MPa) at 15°C. In some markets, 165 bar (16.5 MPa) is preferred to maximise gas content per cylinder. Our ZW series covers both: /150 and /165 suffix variants share the same frame — only stage ratios and final-stage design differ.
Large Industrial Projects and EPC Procurement
For air separation unit integration and steel mill oxygen supply, the compressor is specified against a process data sheet to API 618 Fifth Edition. We supply fully assembled skid-mounted packages — compressor, motor, inter-stage coolers, separators, instrumentation, control panel and interconnecting piping on a single baseplate — minimising site installation time. ATEX and explosion-proof configurations available.
Maintenance and Total Cost of Ownership
Lifetime cost is dominated by energy (60–80%) and maintenance (15–30%). Oil-free reciprocating designs have no oil changes, no oil filter elements, no separator cartridges. Primary consumables are piston rings (15,000–25,000 hr interval) and valve plates (8,000–12,000 hr). Explore the full product catalogue or contact us for a comparative analysis.
常见问题
An oxygen booster compressor is specifically designed for pure oxygen service. The critical differences are: (1) oil-free compression throughout — lubricating oil and oxygen are incompatible at pressure due to combustion risk; (2) material selection compatible with oxygen service (avoiding aluminium alloys, certain plastics and copper alloys at high concentrations); (3) internal surface cleanliness standards — all wetted surfaces are degreased and cleaned to oxygen service standards before assembly; and (4) conservative design margins for pressure and temperature. A standard air compressor cannot be safely repurposed for oxygen service.
Yes. Our ZW, LW and DW series accept inlet pressures from atmospheric (approximately 0.1 MPa absolute) upward. PSA oxygen generators typically output at 0.3–0.6 MPa. We recommend installing a buffer receiver between the PSA and the booster to smooth out pressure fluctuations during the PSA regeneration cycle. The booster inlet low-pressure shutdown ensures the machine stops safely if PSA output falls below the minimum acceptable inlet pressure.
Our compressors are designed and manufactured to API 618 (Reciprocating Compressors for Petroleum, Chemical and Gas Industry Services). ISO 9001 quality management certification is held for our manufacturing facility. CE marking is available for European markets. Pressure vessel components are manufactured and tested to relevant national pressure vessel standards. For projects requiring specific regional certifications, please discuss your requirements with our engineering team before order placement.
Routine maintenance on our ZW, LW and DW series is minimal by design. External bearing lubrication requires one grease application per year. Valve plates and piston rings are the primary wearing components; inspection intervals depend on operating hours and gas conditions but typically fall in the range of 8,000–12,000 operating hours for valve inspection and 15,000–25,000 hours for piston ring replacement. There are no oil changes, no oil filter elements, and no oil separator cartridges — eliminating the highest-frequency maintenance items found on oil-injected compressors.
Yes. For large industrial and EPC projects, we supply fully assembled skid-mounted packages including the compressor, drive motor, inter-stage coolers and moisture separators, process and utility piping, instrumentation and safety devices, and a PLC-based control panel with local HMI. The package is factory-assembled, pressure-tested and performance-tested before shipment, minimising site installation time. ATEX and explosion-proof configurations are available for hazardous area classification. Contact us with your project data sheet for a technical and commercial proposal.
