Turbo Machinery Know-How

After two years in EPT Clean Oil focused on Lubricant Chemistry Management of Turbo Machinery Oils, Decided to make this summary about Turbo Machinery.

Turbo machinery refers to a class of machines that use a rapidly rotating impeller or rotor to convert energy from a fluid, typically a gas or liquid, into mechanical energy. These machines are widely used in various industries, including power generation, oil and gas, chemical processing, and aerospace. In this article, we will explore the different types of turbo machinery and their applications.

1. Centrifugal Compressors: Centrifugal compressors are used to compress gases by accelerating them in a radial direction through an impeller. They are widely used in natural gas processing, petrochemicals, and refinery applications. Centrifugal compressors are preferred for applications where high volume flow rates and moderate compression ratios are required.
2. Axial Compressors: Axial compressors are used to compress large volumes of air or gas in a continuous flow. They use a series of rotating and stationary blades to compress the fluid. Axial compressors are commonly used in gas turbines for power generation, as well as in aircraft engines.
3. Gas Turbines: Gas turbines are a type of turbine that uses a combustion process to generate high-temperature and high-pressure gas that drives a turbine. They are used for power generation, aviation, marine propulsion, and industrial applications.
4. Steam Turbines: Steam turbines use high-pressure steam to drive a turbine, which converts the energy into mechanical power. They are commonly used in power plants to generate electricity, as well as in marine propulsion and industrial applications.
5. Hydraulic Turbines: Hydraulic turbines are used to convert the energy of moving water into mechanical energy. They are commonly used in hydroelectric power plants, where the energy of falling water is used to turn a turbine, which generates electricity.
6. Turbochargers: Turbochargers are used to increase the power output of internal combustion engines by compressing the air that enters the engine. They are commonly used in automotive and marine engines, as well as in some stationary power generation applications.
7. Turbo-expanders: Turbo-expanders are used to extract energy from a process stream and convert it into mechanical energy. They are commonly used in natural gas processing, petrochemicals, and cryogenic applications.

here are some more specific applications for each type of turbo machinery:
