Iranian Specialists Indigenize Centrifugal Compressors
“Centrifugal compressors are classified as dynamic compressors due to their radial thrust flow. These compressors increase the kinetic energy of the cooled gas by using rotating blades, and as a result, the pressure and temperature of the fluid also increase,” said Alireza Sadri, the managing director of the knowledge-based company.
Noting that centrifugal turbocompressors can produce a very high volume of compressed fluid, equivalent to several smaller compressors from other technologies, such as screw, he said, “These features play an effective role in optimizing energy consumption, increasing production efficiency, and decreasing costs. Also, with their high speed, they produce continuous and uniform compressed air, which prevents shocks in the consumption network.”
“These compressors are divided into two types of single-stage and multi-stage. Each of these categories can be divided into drip, pressurized and oil-free types in terms of lubrication system. The oil-free type, by using frictionless magnetic bearings, reduces mechanical wear and improves reliability and efficiency. These compressors have an energy production capacity of up to 35,000 kW and are very suitable for industries that require high pressure. In addition to having a compact and lightweight structure, the compressors are also able to work with a wide range of fluids, including helium and liquid nitrogen,” Sadri said.
A centrifugal compressor is a type of dynamic compressor used to increase the pressure of a gas by converting its kinetic energy into potential energy.
Commonly used in a variety of industrial applications to compress gasses (such as air, natural gas, and refrigerants), its main role is to move gas around. It thus provides compressed air for a wide range of applications, such as pneumatic tools, or manufacturing processes, as well as being key in many high-end refrigeration applications.
It can also be referred to as an impeller compressor, a radial compressor or a turbo compressor, and it is considered as part of the other types of refrigeration compressors.
