Turbine blade is one of the important components of the turbine, usually located on the shaft and used to support andconnect the turbine blades. It bears the huge pressure and load caused by the centrifugal force and high-speed rotationof the turbine blades.
The working principle of high-temperature alloy turbine blades involves aerodynamicprinciples and thermodynamic principles.
Aerodynamic principle:
The aerodynamic principle of turbine blades is based on theprinciple of fluid dynamics. When high-temperature and high-pressure gas passes throughthe turbine blades, the airflow will generate a pressure difference on the blade surface, causingthe pressure on both sides of the blade to be different. This pressure difference causes theblades to generate thrust, which drives the turbine disk to rotate. The shape and aerodynamicdesign of turbine blades will affect the flow and pressure distribution of airflow on the bladesurface, thereby affecting the thrust and rotation efficiency of the blades.
Thermodynamic principles:
Turbine blades work in high-temperature and high-pressureairflow, so they need to have good heat resistance and corrosion resistance. High-temperaturealloy materials are widely used in turbine blade manufacturing because of their excellenthigh-temperature strength and oxidation resistance. The cooling system of turbine blades alsoplays an important role by introducing cooling media, such as cooling air or liquid, into theinterior or surface of the blades to reduce the surface temperature of the blades and maintainthe stability of the blade structure and material performance.
In summary, high-temperature alloy turbine blades convert gas kinetic energy into mechanicalenergy by utilizing the pressure difference generated by aerodynamic principles, and ensure thestability and durability of the blades in high-temperature and high-pressure workingenvironments through thermodynamic principles. Its design and manufacturing need to fullyconsider aerodynamic performance, material selection, cooling technology and other factorsto ensure that the blades can effectively drive the turbine and operate stably for a long time.
features
The turbine blade is the main support structurefor fixed blades. The blades are fixed on thedisk to form a rotating blade array. Theseblades generate power through the impact ofairflow, thereby pushing the turbine disk torotate and driving related mechanicalequipment to operate.
The turbine blade bears the centrifugal force andmomentum generated by the turbine blades,converts the kinetic energy of the airflow intomechanical energy, and provides power tosupport the operation of the turbine. Duringtheir high-speed rotation, they convert air flow energy into rotational kinetic energy on the shaft.
The design and manufacturing of theturbine disk need to ensure that it hassufficient strength and rigidity to withstand thecentrifugal force and inertial force caused byhigh-speed rotation. At the same time, theyneed to be balanced and aligned to ensurestable operation of the turbine.
