　　Principle disassembly and typical application of centrifugal air compressor? In the field of industrial gas power, centrifugal air compressor has always had the title of "power heart". Different from the common screw machine or piston machine, it is famous for its oil-free operation, large flow and high stability, and is an indispensable equipment for modern large-scale process industry. In this paper, Turbo-Tech compressor will disassemble the core technical logic and typical application of centrifugal air compressor for your system based on the bottom pneumatic principle and the pain points of actual working conditions.

　　Principle disassembly and typical application of centrifugal air compressor

　　Ⅰ. Core principles

　　Many people's intuitive understanding of the centrifuge stays in "the impeller rotates at high speed to throw the air out", but from the perspective of engineering thermodynamics, it is a precise continuous energy conversion system. The compression process of centrifugal air compressor is divided into three steps:

　　1. kinetic energy acquisition: the motor drives the multi-stage impeller (usually 2-10 stages) to reach the speed of more than 10,000 revolutions, and the gas makes forced circular motion with the blades in the impeller runner to obtain extremely high linear speed;

　　2. Pressure rise: when the high-speed airflow enters the diffuser, the cross section of the flow passage gradually expands and the flow velocity decreases. According to Bernoulli equation, kinetic energy is converted into static pressure energy;

　　3. Cooling and recompression: Single-stage compression will produce a significant temperature rise, so an intercooler must be arranged between stages to reduce the inlet temperature of the next stage, which can save energy and avoid surge risk.

　　Ⅱ.The typical application scene portrait

　　Petrochemical and natural gas: catalytic cracking, hydrogenation process gas transportation, pressurization of long-distance natural gas pipeline, oil and gas recovery and continuous gas supply in refining and chemical units.

　　Electric energy: instrument and control gas in thermal power plant, gas turbine inlet pressurization, nuclear power auxiliary system and preparation of new energy (such as hydrogen energy).

　　Iron and steel metallurgy: large-scale gas consumption in blast furnace blast, converter/electric furnace stirring, oxygen preparation (air separation unit) and sintering process.

　　Electronics and semiconductors: Clean workshops such as wafer manufacturing and chip packaging need Class0 all-oil free compressor air to avoid product pollution.

　　Air separation and gas separation: large-scale air separation devices (oxygen production, nitrogen production and argon production) depend on their large-flow continuous compression characteristics.

　　Environmental protection and water treatment: large sewage treatment plant aeration system, landfill gas collection and waste gas treatment facilities.

　　Textile and papermaking: air-jet weft insertion, pneumatic control system of loom and continuous power source of large papermaking machinery.

　　The above is an introduction to the principle disassembly and typical application of centrifugal air compressor, which is a continuous and stable guarantee without oil and gas source. If your production line is facing the expansion of gas consumption scale or the bottleneck of product yield caused by oil content, you may wish to recalculate the equipment scheme from the "full return cycle".
