As a core equipment in the fields of thermal power generation and ship power, steam turbines rely on steam expansion to drive rotor rotation, efficiently converting thermal energy into mechanical energy. They have significant advantages such as high power, stable operation, and high efficiency, and are widely suitable for diverse scenarios such as thermal power, nuclear power, and industrial drive. Its structure is precise, mainly composed of key components such as rotor, stator, partition, bearings, etc. During the operation and maintenance process, the standardization of disassembly operations directly affects the quality of equipment maintenance and subsequent operational safety.
In the disassembly process of steam turbine components, the chain hoist is a manual lifting tool that has become the preferred choice for on-site operations due to its flexible, convenient, precise and controllable characteristics. Compared to electric lifting equipment, chain hoists do not rely on power sources and are suitable for various working environments such as workshops and outdoors. They are particularly suitable for lifting components in narrow spaces inside steam turbines, effectively avoiding the problems of cumbersome wiring and limited space of electric equipment.
Hand pulled hoists can achieve smooth lifting and precise positioning of components by manually driving the lifting chain up and down. Whether it is lightweight partitions, blades, or oversized bearing seats, they can adjust the lifting height and position with the help of the chain, accurately docking and dismantling points, and avoiding collision damage to components. At the same time, its operation is simple, and a single person can complete the preparation and control of the task, greatly reducing manpower investment, improving disassembly efficiency while reducing work intensity, truly achieving time-saving and labor-saving.
Relying on the precise lifting capability of the chain hoist, the safety and standardization of the dismantling operation of the steam turbine are guaranteed, laying a solid foundation for subsequent maintenance and replacement of parts, helping the equipment to quickly resume operation, and ensuring the smooth progress of the production process.
