1. Centrifugal Compressor Advantages
1. The centrifugal compressor has large air volume, simple and compact structure, light weight, small unit size and small footprint.
2. Balanced operation, reliable operation, high operation rate, less friction parts, less spare parts, less maintenance costs and less personnel.
In the chemical process, the centrifugal compressor can be absolutely oil-free compression process for chemical media.
4, centrifugal compressor is a kind of rotary motion machine, it is suitable for industrial steam turbine or steam turbine directly drag. For general large chemical plants, by-product steam is commonly used to drive industrial turbines as power, which provides the possibility for comprehensive utilization of heat energy. However, the centrifugal compressor also has some disadvantages
Performance holding point of axial flow compressor
The efficiency is relatively high, the single-machine efficiency can reach 86% ~ 92%, which is 5% ~ 10% higher than that of centrifugal compressor, the circulation capacity per unit area is large, the radial size is small, and the suitable publicity flow rate is more than 1500 m3/min. The single-stage pressure is relatively low, and the single-cylinder multi-stage pressure ratio can reach 11. Compared with centrifugal compressor, the stable working condition area of static vane non-adjustable axial compressor is narrow, and at constant rotating speed, flow changes are relatively small, and pressure changes are large. In addition, the structure is relatively simple and the maintenance is convenient. Therefore, the axial flow compressor is ideal for medium and low pressure, large flow, and the load is basically unchanged. The full static vane adjustable axial flow compressor can expand the stable working condition area of the compressor, make up for the lack of static vane non-adjustable axial flow compressor, and the purpose can improve the efficiency of the compressor and reduce the starting power. At present, refineries mainly use fully static blade adjustable axial flow compressors.
