Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to polishing equipment for producing steam turbine blades. Background Art

[0002] A steam turbine is a device that converts thermal energy into mechanical energy, and is mainly used for power generation and driving machinery. Its working principle is to use high-temperature and high-pressure steam to drive the turbine blades to rotate, thereby generating rotational mechanical energy. Steam turbine blades are an important part of steam turbines. They are key components that directly receive steam energy and convert it into mechanical energy. During production, steam turbine blades are usually polished using a polishing machine.

[0003] Most traditional steam turbine blade production polishing equipment lacks the function of cleaning dust during the polishing process. Metal materials will produce tiny particles due to wear, which will be released into the air to form dust. The abrasive used will also wear and produce solid particles when in contact with the blades. The dust generated during the polishing process will enter the air, causing the air quality to deteriorate. Therefore, those skilled in the art provide a steam turbine blade production polishing equipment to solve the problems raised in the above background technology. Utility Model Content
