The centrifugal compressor features a modular design that integrates key proprietary components such as the main unit, cooling system, oil station, motor, and electrical control system. This design offers a compact structure, high reliability, energy efficiency, and reduced assembly complexity, making installation quick and easy. With its advanced engineering, the compressor ensures a continuous, stable supply of oil-free, high-quality compressed air, ideal for a wide range of industrial applications.
The compressor is equipped with an aviation-grade titanium alloy impeller known for its high efficiency and exceptional reliability. It features a special corrosion-resistant coating—commonly referred to as the “gold impeller”—designed to withstand the impact of aggressive and special gases. The impeller is forged using advanced five-axis precision machining and incorporates a ternary flow, backward-curved design for superior aerodynamic performance. Its large-flow configuration, combining long and short blades, ensures reduced flow loss and excellent adaptability to varying working conditions, making it ideal for demanding industrial environments.
The bearings and seals feature a horizontally split structure, allowing for easy and convenient maintenance by simply lifting the gearbox’s upper cover. The rotor shaft utilizes a thrust ring design, eliminating the need for a thrust bearing. This simplified structure enhances transmission efficiency and significantly improves the overall reliability of the equipment.
The system offers stable and efficient performance with stepless adjustment for precise control. It includes a self-contained protective cover that ensures safe operation and effective dust protection. Designed with a robust fork structure, it delivers high reliability even in demanding conditions. Additionally, the use of electric actuators and positioners eliminates the need for external instrument air, simplifying installation and reducing maintenance requirements.
The system features a straight tube design that eliminates the need for core pulling during maintenance, reducing maintenance time by up to 90%. With no wearing parts, it ensures minimal maintenance costs. Its large-scale construction allows for highly efficient heat exchange, low water consumption, and ultra-low gas pressure loss—achieving 1–2% energy savings compared to traditional designs. The patented variable cross-section structure enhances gas-liquid separation performance. A stainless steel support core minimizes corrosion risk, while the design’s absence of fasteners eliminates any chance of impeller damage due to loose components. Dual-end support eliminates the risk of resonance-related damage to the cooler core. Additionally, the long-life steam trap offers rust-free, efficient water drainage with zero air loss, ensuring durability and consistent performance.
Compressors equipped with Inlet Guide Vanes (IGVs) are 7–9% more efficient than those using butterfly valves, thanks to the IGV’s intake pre-rotation effect, which aligns the incoming airflow with the impeller’s angle for optimized efficiency. IGVs also offer a broader adjustment range, resulting in smoother regulation and minimal airflow disturbance. Additionally, the compressor incorporates a highly reliable venting control valve capable of operating across a full 0–100% flow range. Engineered for constant pressure control, this valve is designed to handle up to 200,000 load/unload cycles per year, ensuring long-term reliability and performance.
The system is equipped with an integrally welded oil tank for enhanced strength and durability, along with an oil tank heater to maintain optimal oil temperature. It includes an oil level sight glass and a low oil level alarm with an automatic shutdown function to ensure safe and reliable operation. The spindle is directly connected to the main oil pump for efficient and consistent oil circulation. A full-flow auxiliary oil pump automatically activates at low oil pressure and is equipped with a pressure regulating valve for stable performance. Additional components such as an oil filter, check valves, and safety valves are included to ensure clean lubrication and secure system protection.
The system features an advanced PLC control system with a user-friendly 7-inch touch screen interface, making operation intuitive and accessible. It supports automatic dual control, constant pressure control, and self-balancing modes to automatically adjust gas volume based on system demand. All operating parameters are clearly displayed, with options for user-defined parameter settings. The system is equipped with various adjustable alarm and shutdown functions for enhanced safety. Additionally, it includes anti-surge and surge prediction functions to protect the compressor during critical conditions. Communication is supported via DH+, Modbus, Profibus, or Ethernet protocols, allowing seamless integration with industrial control networks.
