Centrifugal compressor

Denair centrifugal compressors adopt a modular design, including proprietary modules such as the main unit, cooling system, oil station system, motor, and electrical control system. They feature a compact structure, reliable operation, energy efficiency, minimal assembly requirements, and easy installation. These compressors ensure the provision of continuous, stable, and oil-free high-quality compressed air, offering users comprehensive industrial gas system solutions.

Pneumatic Design Section

The pneumatic design of Denair centrifugal compressors applies advanced aerodynamic principles, combined with self-developed high-efficiency modeling software and CFD simulations, ensuring optimal inter-stage compression ratio distribution and stability. Additionally, leveraging the long-term product validation experience of Denair's German team, an extensive impeller database, and design software, the pneumatic design achieves superior performance.

Impeller Strength Analysis

Using finite element analysis software, the stress and deformation of the impeller under design conditions are simulated. The stress analysis structure provides a scientific basis for verifying impeller strength, preventing accidents caused by localized stress concentration or insufficient strength during actual operation. The calculated axial and radial deformation values serve as a reference for determining the clearance between the impeller and the intake cylinder, preventing severe failures such as impeller damage due to scraping during operation.

Rotor Dynamic Design

Professionally designed rotors and bearings ensure operation within reasonable oil film temperature, pressure, and thickness, effectively reducing bearing power consumption. By extracting extensive stiffness and damping data from bearings and conducting rotor dynamics analysis, reasonable vibration values are guaranteed. The rated speed is set to operate away from critical speeds, enhancing overall machine stability.

High Reliability Axial

Carefully Designed, Stable and Reliable

Through specialized rotor dynamics design, tilting pad bearings with high load capacity and low vibration are employed. The bearing bush can automatically align according to changes in load and temperature, ensuring stable operation under various harsh conditions.
