Centrifugal Compressor

Centrifugal compressor is a kind of compressor that utilizes a high-speed rotating impeller to do work on the gas, so that the pressure and kinetic energy of the gas in the centrifugal field are increased.

In the early days, the centrifugal compressor is mainly used to compress air, and is only suitable for low and medium pressure and very large volume occasions. With the demand of various production processes and the improvement of centrifugal compressor manufacturing technology and design technology, centrifugal compressors have been applied to high pressure areas.

Centrifugal compressor class structure

Centrifugal compressors have various structural types such as single-stage, double-stage and multi-stage. Single-stage compressor is mainly composed of suction chamber, impeller, diffuser, worm shell, etc. For multi-stage compressor, there are also components such as bends and reflows.

Components

The centrifugal compressor adopts modular design, including the host, cooling system, oil station system, motor, electric control system and other proprietary modules. It has the advantages of compact structure, reliable operation, energy saving and high efficiency, less assembly and easy installation. It can ensure to provide users with continuous, stable, oil-free compressed air of high quality.

Impeller

Centrifugal compressor's pneumatic design applies aerodynamic principles, combined with self-developed modeling software, CFD simulation and other means, to ensure the inter-stage compression ratio distribution and stability; at the same time, combined with the long term product validation and design experience of Denel's technical R&D team, impeller database and design software, to ensure the stability of the pneumatic design.

Rotor Dynamics Design

The rotor and bearing design ensures that it can operate under reasonable oil film temperature, pressure and thickness, effectively reducing bearing power consumption. Extracting a large amount of bearing stiffness and damping data for rotor dynamics analysis, to ensure a reasonable rotor vibration value, to ensure that the rated speed setting is far from the critical speed operation, and to enhance the stability of the whole aircraft.

Integral Casting Gearbox-Modular Integrated Assembly

Horizontal split gear box and all levels of worm shell integrated casting, cooler box body overall casting, modular design. Compared with the welded gear box split structure, the main structure has high strength, less machining surface, reliable operation, no assembly error between all levels of worm shells and gear box body, no deformation, low noise, low vibration. Processing, assembly, transportation, on-site installation and maintenance are simple and convenient.

High Reliability Bearing

Through the professional design of rotor dynamics, it adopts tilting tile bearings with strong load capacity and low vibration. The bearing tilting pads can be automatically centered according to the load and temperature changes, which ensures the stable operation of the unit in dealing with a variety of harsh working conditions.

High Performance IGV

The electric actuator drives the winged stainless steel vanes to provide precise control of the inlet guide vane opening, changing the pre-spin value of the inlet air to improve the operating efficiency of the centrifugal compressor. When the compressed air requirement is reduced, the IGV saves up to approximately 9% of the energy consumption, allowing the centrifugal compressor to operate in a highly efficient and energy-saving manner.

Feature

Compact structure, good sealing effect, less leakage phenomenon, small size, thus the unit footprint and weight are much smaller than the same volume of piston compressor.
Large flow rate, high power, conducive to energy saving. Turbomachinery flow through the impeller medium, has been continuous, the cylinder volume is larger, the impeller can rotate at high speed, so the turbomachinery exhaust flow and power can be greatly increased. So the centrifugal compressor exhaust gas uniformity, airflow without pulse.
Smooth operation, reliable operation, so it has a high operating rate, a flat performance curve, a wider range of operations, maintenance costs and fewer personnel.
Fewer wearing parts, long operating cycle, fewer and simpler moving parts, and low manufacturing precision, so its manufacturing costs are relatively low and high reliability. Easy to automate and large-scale.
Centrifugal compressor compression process can be done without oil, the machine does not need lubrication, which is very important for the production of many industries.
