In a centrifugal compressor, the high-speed rotating impeller exerts
centrifugal force on the gas and expands the gas in the expansion channel,
resulting in an increase in gas pressure. In the early days, due to the fact
that this type of compressor was only suitable for low, medium pressure, and
high flow situations, it was not noticed by people. Due to the development of
the chemical industry and the establishment of various large-scale chemical
plants and refineries, industrial compressor have become a key machine for
compressing and transporting various gases in chemical production, occupying an
extremely important position.




(1) Horizontal split centrifugal compressor
This type of compressor has a horizontal dividing surface that divides the
cylinder into upper and lower halves, which are connected by bolts at the
dividing surface. This structure is easy to disassemble and is suitable for
medium and low pressure applications.
(2) Cylindrical centrifugal compressor
The cylindrical compressor has two layers of cylinders, inner and outer. The
outer cylinder is cylindrical with end caps at both ends. The inner cylinder is
vertically divided and assembled before being pushed into the outer cylinder.
This structure has high strength, good sealing performance, and good rigidity,
but it is difficult to install and inconvenient to maintain. It is suitable for
high-pressure or situations that require good sealing performance.
(3) Multi axis centrifugal compressor
It is driven by a large gear in a gearbox, which drives several small gear
shafts. One or both ends of each shaft are equipped with a first stage
impeller, which enters the air axially and discharges radially. The impellers
are connected to each stage through pipelines. This structure is simple, small
in size, and suitable for compression of medium to low pressure air, vapor, or
inert gases.

Application
In a Industrial Centrifugal Air Compressors, the high-speed rotating impeller
exerts centrifugal force on the gas and expands the gas in the expansion
channel, resulting in an increase in gas pressure. In the early days, due to
the fact that this type of compressor was only suitable for low, medium
pressure, and high flow situations, it was not noticed by people. Due to the
development of the chemical industry and the establishment of various large-
scale chemical plants and refineries, centrifugal compressors have become a key
machine for compressing and transporting various gases in chemical production,
occupying an extremely important position. With the achievements of gas
dynamics research, the efficiency of centrifugal compressors has been
continuously improved. Due to the successful development of key technologies
such as high-pressure sealing, small flow narrow impeller processing, and multi
oil wedge bearings, a series of problems related to the development of
centrifugal compressors towards high pressure and wide flow range have been
solved, greatly expanding the application range of centrifugal compressors. As
a result, they can replace reciprocating compressors in many occasions and
greatly expand their application range. The pressure of industrial high-
pressure centrifugal compressors ranges from (150~350) × 105Pa, while the
pressure of centrifugal compressors used for gas injection in offshore oil
fields can reach up to 700 × 105Pa. As a centrifugal blower used for blast
furnace blowing, the flow rate can reach up to 7000m3/min, the power is
52900KW, and the speed is generally above 10000r/min.
Some basic chemical raw materials, such as propylene, ethylene, butadiene,
benzene, etc., can be processed into important chemical products such as
plastics, fibers, rubber, etc. In petrochemical plants that produce this basic
raw material, centrifugal compressors also play an important role and are one
of the key equipment. In addition, centrifugal compressors are also crucial
equipment in other industries such as petroleum refining and refrigeration.
