The turbine impeller is the core rotating component in the turbine. Its main function is to convert the kinetic energy of the fluid into mechanical energy. The turbine impeller consists of a series of precisely arranged blades that are fixed to the hub to form a complete wheel structure. When the fluid passes through the impeller, the fluid exerts force on the blades, pushing the impeller to rotate, thereby driving the shaft connected to the turbine impeller to rotate, and finally converting the kinetic energy into mechanical energy for driving generators, compressors, fans or other mechanical equipment.
Aerospace: In aircraft engines, turbine impellers are key components that convert high-temperature, high-pressure gases produced by fuel combustion into thrust. They are also used in propulsion systems for various spacecraft.
Power Generation: In gas turbines and steam turbine power plants, turbine impellers convert heat energy generated by natural gas, coal gas or atomic energy into electrical energy. Such turbines are often found in stand-alone power stations or as part of large power plants.
Industrial Processes: In various industrial processes, such as chemical processing and oil refining, turbine impellers are used in various pumps and compressors to provide necessary power or pressure support.
Transportation: In the field of marine transportation, turbine impellers are also used in turbine propulsion systems used by ships. In addition, high-speed trains and some special vehicles may also use turbine technology.
Automotive: In the automotive industry, turbochargers use turbine impellers to increase the amount of air intake in the engine, thereby increasing engine power and efficiency.
Ocean and Wind Energy: In wind turbines, turbine impellers capture wind power and convert it into electrical energy. Similarly, turbine impellers are also used in ocean energy power generation devices, such as tidal and wave power generation devices.
The turbine wheel provides a support structure for blade installation to ensure that the blades can be correctly positioned and rotated.Convert kinetic energy: The turbine wheel converts the kinetic energy of the airflow into mechanical energy on the shaft through the rotation of the blades after being impacted by the airflow.
The turbine impeller material must have good high temperature resistance and be able to work stably for a long time in a high temperature environment.
The turbine wheel converts the kinetic energy of the airflow into mechanical energy on the shaft through the rotation of the blades after being impacted by the airflow.
The bearing holes on the turbine wheel are used to connect the turbine wheel and the shaft to support the rotation of the wheel on the shaft.
Automobile turbocharger impellers: The speed of automotive turbocharger impellers is usually between tens of thousands and hundreds of thousands of rpm. These impellers need to rotate quickly to provide sufficient turbocharging effect, thereby increasing the engine’s air intake and power output.
Industrial turbomachinery impellers: The impeller speed range in industrial turbomachinery is relatively wide, usually between thousands and tens of thousands of rpm, and the specific speed depends on the design specifications, working environment and power requirements of the turbomachinery.
Aircraft engine turbine impellers: Turbine impellers in aircraft engines usually operate at very high speeds, reaching more than tens of thousands of rpm, or even more than 100,000 rpm. These impellers need to withstand the impact of high-temperature and high-pressure airflow, and need to have excellent strength and fatigue life.
Ship turbine propeller impellers: The impeller speed range in ship turbine propellers is relatively low, usually between hundreds and thousands of rpm, and the specific speed depends on the size, speed and propulsion requirements of the ship.
