Features of Centrifugal Compressors
Centrifugal compressors are now being widely used in many fields,
such as Chemical and Petrochemical, Midstream, Fertilizer, Power
Generation, Industrial Gases, Textile Industry, LNG industry, this
is mainly because it has below advantages compared with piston
compressors:
1. The centrifugal compressor has a large gas volume, simple and
compact structure, light weight, small unit size and small floor
space.
2. the operation is balanced, the operation is reliable, the
operation rate is high, and the friction parts are few, because the
spare parts need less usage, the maintenance cost and the personnel
are small.
3. In the chemical process, the centrifugal compressor can achieve
an absolutely oil-free compression process for chemical media.
4. The centrifugal compressor is a kind of rotary motion machine,
which is suitable for direct dragging of industrial steam turbines
or gas turbines.For general large-scale chemical plants, it is
often used as a by-product steam-driven industrial steam turbine to
provide power for comprehensive utilization of thermal energy.
Application Fields
Centrifugal compressors are widely used in large-scale chemical
industry, oil refining, metallurgy, oxygen production,
pharmaceutical and other fields because of their outstanding
advantages. It plays an important role in the relevant production
equipments, and is known as the "heart" of the production line.The
GDC series oil-free centrifugal air compressors are uniquely
designed to ensure continuous and stable operation over a wide
operating range. Their efficient operating efficiency meets the gas
supply requirements of various process flows, providing absolutely
oil-free high-flow compression for all industries.

Advantages
1. 100% Oil-free
Perfect separation structure between the lubricating oil part and
the air compression part ensures 100% clean and oil-free compressed
air.
2. Anti-surge control system
The system consists of surge pressure sensor and motor current
sensor. When the change ratio of the last stage exhaust pressure
and the change ratio of the motor current is higher than the set
value of surge, PLC will regard this situation as surge, and then
alarming system will work and compressor will stop meanwhile
discharging the air. Through the advanced method of continuously
monitoring the changes of the two parameters of system pressure and
current at the same time, it can avoid the misoperation of surge
only by single signal judgment, and effectively prevent the
occurrence of surge.
3. Wide range of applications
Compressors from single stage to multiple stages (6 stage) are all
available, we provide customized products.
4. Durability
Stable quality assurance system to insure the compressor
performance
The modern industrial craft adopted in impeller making
The centrifugal air compressor is developed through the cooperation
between domestic top experts in aviation air dynamics and GoodSeaA
research team. The key part of the centrifugal air compressor is
impeller, which is designed with the advanced aero-engine design
software Axstream, verified with the aero-engine strength
verification software ANSYS and processing on 5-axis CNC machine. During the making process, the three dimention flow field simulation is carried out by using
aerodynmic impeller simulation softwere NUMECA.
