Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbing equipment, in particular to a shock absorbing mechanism for a steam turbine unit. Background Art

[0002] A steam turbine is a highly efficient energy conversion device. Its core principle is to utilize the thermal energy of steam to drive the rotor, thereby generating mechanical work. A steam turbine consists of a rotating part (rotor) and a stationary part (stationary body). The rotating part includes the moving blades, impeller, and main shaft, while the stationary part includes key components such as the cylinder, steam chamber, and partitions. After the steam is reduced in pressure and increased in speed in the nozzle, it impacts the moving blades, driving the rotor to rotate and converting thermal energy into mechanical energy. Steam turbines are widely used in power generation, ship propulsion, and other fields, and are an indispensable and important piece of equipment in modern industry.

[0003] When steam turbines operate at high speeds, they generate high-frequency vibrations due to factors such as airflow and mechanical imbalance. Excessive vibrations can directly affect equipment stability, potentially loosening or damaging components, and ultimately impacting power generation efficiency and equipment lifespan. Furthermore, excessive vibrations generate high noise levels, which not only negatively impact the work environment but also pose safety risks. Prolonged exposure to noisy environments can also damage workers' hearing and other health issues. Utility Model Content
