One less leaf, or what is symmetry?
The principle of steam turbine rotor design is to convert heat source energy into mechanical energy through a high-speed rotating impeller, thereby driving generators and other equipment to operate. One less blade or symmetry refers to the blade shape design of the steam turbine rotor. The purpose of blade design is to enable the steam turbine rotor to more effectively convert heat source energy into mechanical energy when rotating at high speed. For example, one less blade can reduce the gap between the blades and increase the speed and efficiency of the impeller. ； Symmetrical blades can balance the force of wind on the impeller and reduce wind noise. .
The first picture lacks left and right symmetry. What does that mean?
The design principle of the steam turbine rotor is to convert the kinetic energy of high-speed rotation into working energy, which plays a key role in the entire steam turbine power generation system. The steam turbine rotor generally consists of several parts, including the runner, blades and rotating shaft. The runner is made of high-strength and heat-resistant material, usually cast steel or forged steel, with high strength and fatigue resistance. The blades are used to push steam out of the hub to create torque. The rotating shaft connects the runner and the transmission device and is used to transmit the rotational force to the generator or other mechanical device. The design of the entire rotor must take into account many factors, such as speed, temperature, stress, vibration, etc., and take certain measures to ensure safe and reliable operation. .
I have never seen a piece missing. My first feeling was that it was broken.···
There are also symmetrical steam turbine impellers with one less piece, which reduces the centrifugal force and inertia force, thereby making the impeller rotate faster, reducing airflow interference, and improving the efficiency of the steam turbine.
It is estimated that one piece is broken, so I will reduce one piece diagonally to ensure balance: lol
I guess it's to adjust the critical speed away from the operating speed :lol
Master, hurry up and post, I want to learn* Got it
