Engineered to deliver 5.3 m³/min at 1.60 MPa discharge pressure, the LW-5.3/16 is a two-stage, two-row oil-free piston nitrogen compressor purpose-built for high-pressure nitrogen injection, gas cylinder filling, and specialized petrochemical inerting operations. Zero oil contamination, compact footprint, and optimized for medium-duty industrial service at elevated pressure.

Өнімге шолу

The LW-5.3/16 nitrogen compressor occupies a specialized niche within our oil-free piston compressor portfolio, engineered for applications that demand both moderate flow capacity and significantly elevated discharge pressure. With a rated capacity of 5,3 м³/мин and an impressive 1,60 МПа шығару қысымы, this unit bridges the gap between conventional low-pressure nitrogen boosters and ultra-high-pressure gas filling systems.

What distinguishes the LW-5.3/16 is its толығымен майсыз сығымдау механизмі utilizing self-lubricating PTFE composite piston rings and rider bands. This design philosophy eliminates any possibility of hydrocarbon contamination in the nitrogen product stream, making the unit immediately suitable for high-purity nitrogen cylinder filling, pharmaceutical-grade inerting, and electronics manufacturing where even trace oil content would compromise product integrity. The native oil-free certification achieves ISO 8573-1 0 класына сәйкестік without requiring additional downstream purification equipment.

Оның екі сатылы, екі қатарлы (二列二级) configuration is thermodynamically optimized for the high pressure ratio required to reach 1.60 MPa. The staged compression approach divides the total pressure burden between a low-pressure cylinder and a high-pressure cylinder, with an inter-stage cooler removing the heat of compression to maintain gas temperatures within safe limits. This thermal management is critical for preserving the integrity of the PTFE sealing elements under the demanding conditions of high-pressure operation. The compact dimensions—1947 × 1900 × 2580 мм—and manageable weight of 3,97 тонна make the LW-5.3/16 suitable for installations where space is at a premium.

Technical Specifications – LW-5.3/16

* Барлық сипаттамалар стандартты анықтамалық шарттар бойынша бағаланған (ISO 1217, C қосымшасы). Нақты көрсеткіштер алаңның биіктігіне, қоршаған орта температурасына және кіріс жағдайларына байланысты өзгеруі мүмкін.

Негізгі ерекшеліктері және инженерлік артықшылықтары

1. Жоғары қысымды майсыз PTFE тығыздау технологиясы

The LW-5.3/16 employs a specialized өздігінен майланатын поршень сақинасы және шабандоздық жолақ жүйесі manufactured from high-performance PTFE composites reinforced with glass fiber and bronze particulates. This material formulation is specifically engineered for high-pressure service, achieving a coefficient of friction below 0.08 without any external hydrocarbon lubrication. The rings are dimensionally stable at temperatures up to 180°C, which is essential for managing the thermal loads associated with 1.60 MPa discharge pressure. For operators requiring high-purity nitrogen, this design delivers ISO 8573-1 0 класының жергілікті сәйкестігі, eliminating the need for costly downstream oil-filtration systems.

2. Төтенше қысым қатынастары үшін екі сатылы сығымдау

The екі сатылы сығымдау архитектурасы is indispensable for achieving the 1.60 MPa discharge pressure from typical inlet conditions of 0.05–0.10 MPa. By dividing the overall pressure ratio between a low-pressure cylinder and a high-pressure cylinder, the LW-5.3/16 maintains manageable discharge temperatures per stage. A dedicated high-efficiency shell-and-tube intercooler between stages removes the heat of compression, keeping gas temperatures below 160°C even at maximum continuous load. This thermal management strategy is critical for preserving PTFE ring integrity under high-pressure conditions and extends valve plate service life by approximately 35% compared to single-stage designs attempting equivalent pressure ratios.

3. Compact Design with Robust Construction

Despite its high-pressure capability, the LW-5.3/16 maintains a remarkably compact footprint of 1947 × 1900 × 2580 мм. This dimensional efficiency is achieved through a vertically oriented crankcase design that minimizes longitudinal space requirements while providing adequate maintenance access. The main frame is cast from GG25 сұр шойын with integral cooling water passages, and the two-row opposed-cylinder arrangement provides natural first-order force cancellation. At 3,97 тонна, the unit can be transported and positioned using standard forklift equipment, eliminating the need for specialized rigging during installation or relocation.

4. Стандартты 380В тікелей желілік қозғалтқыш жетегі

The LW-5.3/16 is powered by a 55 кВт, 380 В, 50 Гц үш фазалы асинхронды қозғалтқыш conforming to IEC 60034-1 efficiency class IE3. The standard low-voltage configuration integrates directly into existing 380V industrial distribution panels without requiring medium-voltage infrastructure or step-down transformers. This electrical simplicity reduces both capital expenditure and commissioning complexity, making the LW-5.3/16 an attractive option for facilities upgrading from high-pressure bottled nitrogen or membrane separation systems to on-site compression.

Қолдану сценарийлері

Жоғары қысымды азот цилиндрлерін толтыру станциялары

The LW-5.3/16 is ideally suited for азот цилиндрін толтыру операциялары where high-pressure gas must be compressed into standard industrial cylinders at 15–20 MPa. The 1.60 MPa discharge pressure serves as the primary booster stage, feeding a downstream high-pressure compressor or booster pump that achieves the final cylinder charging pressure. The oil-free design is mandatory in cylinder filling applications because any oil contamination would compromise the purity of nitrogen delivered to end-users in food processing, medical, and electronics industries. The 5.3 m³/min capacity supports filling rates of 20–30 cylinders per hour, making it suitable for medium-scale filling stations serving regional industrial gas markets.

Specialized Petrochemical High-Pressure Inerting

In petrochemical operations involving high-pressure reactors, catalyst regeneration systems, and hydrocracking units, nitrogen is required at elevated pressures for reactor inerting, catalyst preservation, and emergency depressurization. The LW-5.3/16 high-pressure nitrogen compressor delivers the 1.60 MPa pressure necessary to overcome reactor operating pressures and maintain positive inert gas flow. The oil-free certification is critical in these applications because any hydrocarbon contamination would poison precious metal catalysts, degrade product quality, and create safety hazards in hydrogen-rich process environments.

Pharmaceutical High-Pressure Inerting & Blanketing

Pharmaceutical manufacturing facilities require high-purity nitrogen at elevated pressures for reactor blanketing, powder conveying, and sterile packaging operations. The LW-5.3/16’s 1.60 MPa discharge pressure is sufficient to drive pneumatic conveying systems that transport active pharmaceutical ingredients (APIs) between process vessels without contamination risk. The oil-free design ensures compliance with FDA 21 CFR 211.72 (equipment cleaning and maintenance) and EU GMP Annex 1 (manufacture of sterile medicinal products), where any oil contamination would render batches unfit for human use.

Electronics High-Pressure Process Gas Supply

Жартылай өткізгіш өндіріс орындары мен электроника құрастыру зауыттары жоғары қысымды азотты қажет етеді wafer handling, chemical vapor deposition (CVD) chamber purging, and lead-free soldering operations. The LW-5.3/16’s 1.60 MPa pressure supports the high-flow pneumatic actuators and process gas manifolds used in advanced packaging lines. The oil-free certification is non-negotiable in electronics applications because even trace oil contamination can cause solder joint defects, delamination of conformal coatings, and catastrophic failure of sensitive optical components.

Материал және құрылыс

The LW-5.3/16 is constructed from premium materials selected for high-pressure nitrogen compatibility, thermal stability, and extended service life:

Барлық қысым көтеретін компоненттер сәйкес жобаланған және жасалған ASME BPVC VIII бөлім 1-бөлім немесе Қытайдың GB 150 стандарттары. Әрбір дәнекерлеу қосылысы ASME V бөлімінің 2-бабына сәйкес 100% радиографиялық тексеруден (RT) өтеді, және әрбір аяқталған қысымды ыдыс ең аз дегенде 30 минут ұстау кезеңі ішінде рұқсат етілген ең жоғары жұмыс қысымының (MAWP) 1,5 есесімен гидростатикалық қысым сынағынан өтеді.

Іргетас және кеңістіктік талаптар

The LW-5.3/16 has a dry weight of 3.97 tonnes and a low center of gravity due to its compact vertical design. A 5-6 тонналық темірбетон төсем is sufficient for stable operation, mounted on elastomeric vibration isolators (natural frequency 8–12 Hz). The two-row opposed-cylinder arrangement inherently cancels first-order inertial forces, minimizing vibration transmission. Required clearances: 1.0 m on the non-drive side for valve maintenance, 0.8 m on the drive side for motor access, and 1.5 m overhead for routine service.

Салқындатқыш судың сипаттамалары

Салқындатқыш суға қажеттілік шамамен 15 м³/сағ at an inlet temperature not exceeding 32°C. The water distribution circuit feeds the cylinder jackets and intercooler in parallel. Acceptable water quality: pH 6.5–8.5, total hardness < 300 mg/L as CaCO₃, chloride < 50 mg/L, suspended solids < 30 mg/L. For installations without reliable municipal water supply, a compact closed-loop cooling tower with a 0.5 m³ buffer tank is recommended.

Алдын алу жұмыстарының кестесі

The oil-free design of the LW-5.3/16 dramatically simplifies maintenance compared to lubricated alternatives. There are no oil changes to schedule, no oil samples to analyze, no filter elements to replace, and no separator cartridges to monitor. The only consumable wear items are the PTFE поршень сақиналары және рульдік белдіктер, which typically achieve 4,000–6,000 hours of service life under clean nitrogen conditions.

Сәйкестік және қауіпсіздік сертификаттары

The LW-5.3/16 nitrogen compressor meets the following international standards and regulatory requirements:

Өнімділік және тиімділік талдауы

The LW-5.3/16 achieves a шамамен 10,38 кВт/м³/мин меншікті қуат тұтынуы of nitrogen delivered at 1.60 MPa discharge pressure. While this specific power is higher than low-pressure models due to the extreme pressure ratio, it remains competitive within the high-pressure oil-free piston compressor segment. For comparison, oil-lubricated alternatives in this pressure class typically consume 11.0–12.5 kW/m³/min, and diaphragm compressors (often selected for oil-free high-pressure service) can exceed 14 kW/m³/min.

Over an 8,000-hour annual operating cycle, the LW-5.3/16’s efficiency advantage versus less efficient alternatives yields approximately 25,000–55,000 kWh of energy savings per year. At $0.08/kWh, this represents $2,000–$4,400 in annual electricity cost reduction. However, the primary economic driver for LW-5.3/16 selection is typically the мұнайға қатысты шығын материалдары мен кейінгі тазарту жабдықтарын алып тастау шекті энергия үнемдеуден гөрі.

The жоғары қысымды азот сығымдауының жалпы меншік құны is dominated by maintenance labor and consumables. The LW-5.3/16’s oil-free design eliminates oil changes ($300–600/year), filter replacements ($150–300/year), separator cartridge changes ($400–800/year), and oil analysis ($100–200/year), delivering total consumable savings of $950–$1,900 annually compared to lubricated alternatives.
