Product Details

The 2SY series two-stage liquid ring compressor and water ring compressor represent a significant technological upgrade developed by Xiamen Taixing. Specifically engineered for high-pressure, high-vacuum, and hazardous gas conditions, this series utilizes a dual-stage series structure to achieve superior compression ratios through isothermal technology. With a stable gas flow range of 1.5 to 30 m³/min and working pressures between 0.3 and 0.6 MPaG (reaching a maximum of 0.8 MPaG), it stands as the premier choice for demanding industrial applications.

Core Features & Advantages

Enhanced Two-Stage Efficiency: The dual-stage series structure ensures more thorough isothermal compression. Compared to single-stage equipment, it reduces energy consumption by 15-20% under the same pressure conditions.
Explosion-Proof Safety: By using a liquid ring to dissipate compression heat, the process remains isothermal. This eliminates spark risks, making it ideal for transporting flammable gases like ethylene, chlorine, benzene, and butadiene.
Superior Medium Adaptability: This water ring compressor can handle gases containing large amounts of water vapor or non-particulate dust. Flow parts are available in cast iron, 304, or 316L stainless steel to resist corrosion.
Robust Design & Easy Maintenance: Features inspection holes on the side covers for direct observation of internal corrosion or scaling. Options for packing seals or double-end mechanical seals ensure zero leakage and simplified upkeep.
Stable & Reliable Operation: Rotating parts operate without contact in the working chamber. Optimized dynamic balance design ensures low vibration and noise, making it perfect for continuous long-term operation.
Dual-Function Versatility: It functions both as a high-pressure compressor (up to 0.8 MPaG) and a high-performance vacuum pump (limit 33 mbar absolute pressure).

Note: 1. Motor power is based on a discharge pressure of 0.55 MPaG. 2. Maximum pressure can reach 0.8 MPaG with adjusted motor power. 3. Performance data is based on air at 20°C, 70% humidity, and 15-20°C water temperature.

Wide Range of Applications

The 2SY series is a versatile solution for industrial gas transportation across various sectors:

Petrochemical: Compression of flammable gases such as vinyl chloride, sulfur dioxide, hydrogen sulfide, and butadiene.
Power Industry: Condenser vacuuming, negative pressure conveying, and gypsum dewatering in desulfurization units.
Mining: Vacuum dewatering, mine gas drainage, and filter matching for dust-laden air.
Food & Beverage: Vacuum packaging, freeze-drying, and bottling with oil-free, clean operation.
General Industry: Vacuum impregnation, drying, and high-pressure gas delivery systems.

Frequently Asked Questions

1. What is the main advantage of the 2SY over the single-stage SY series?

The 2SY series offers a higher compression ratio and discharge pressure with significantly lower energy consumption. It is specifically optimized for high-pressure and high-vacuum requirements that single-stage units cannot efficiently meet.

2. Can it handle highly corrosive gases?

Yes. By selecting 316L stainless steel or rubber-lined components and utilizing a double-end mechanical seal, the 2SY can safely transport corrosive media without leakage.

3. What kind of working fluid is required?

Clean water is standard, though softened water is recommended to prevent scaling. In closed-loop systems, the fluid typically needs replacement every 3-6 months depending on the gas quality.

In summary, the 2SY series two-stage liquid ring compressor redefines the standards for high-pressure fluid equipment. By combining safety, efficiency, and durability, it provides a "high-efficiency, low-consumption" solution for the most challenging industrial environments.

Conclusion: The 2SY Series Two-stage Liquid Ring Compressor is suitable for industries requiring high-pressure, high-purity gas delivery and explosive gas handling. The core advantage is its two-stage isothermal compression, high efficiency, and explosion-proof safety.
