Turbine Blade Rust Removal Shot Blasting Machine For Generator Set, And Steam Turbine Blade Sand Removal And Rust Removal Shot Blasting Strengthening Plan

       The electrical industry is one of the basic industries in a modern country, and its development directly affects the development of the national economy. At present, steam turbine generator sets provide about 75% of the energy for human beings, so the safety, reliability and high efficiency and long-term operation of steam turbines are essential. The heart blade of a steam turbine is directly related to the safety of the entire steam turbine and power plant.

　　The steam turbine blade shot blasting machine can be described as the new favorite of the energy machinery industry nowadays, and the importance of strengthening the blades of the steam turbine blade as a heart-level component is obvious. Today, the editor of Qingdao Wozhou Machinery will talk about the shot blasting strengthening plan for steam turbine blades and the type of shot blasting machine required.

　　 steam turbine blade shot blasting machine is designed to increase the internal surface stress of the steam turbine blade and enhance its hardness, so as to extend its service life and improve the safety of the steam turbine in the later use process.

Steam turbine blade shot blasting strengthening scheme:

       Steam turbine blades are shot blasted for surface treatment. The shot blasting device uses centrifugal force to accelerate the steel shot to a certain speed. The diameter of the centrifugal wheel blade is generally 300-400mm, and the number of revolutions is 1500-3000r/min. The high-speed steel shot flow (50-60m/ s) Throwing to the workpiece for surface cleaning to remove the sticky sand, oxide scale and small flash burrs on the surface of the workpiece to obtain a certain roughness. Increase the shot blasting speed (80-100m/s) through the servo motor for polishing. Make the steam turbine blades form compressive stress and produce deformation strengthening and fine grain strengthening to change the surface mechanical properties and increase the service life of the workpiece. Shot blasting has poor flexibility, and it is easy to produce dead corners that cannot be cleaned on the surface of complex workpieces.

      At present, due to the improvement of the shot blasting device, the shot blasting volume has been increasing (more than 200kg/min, even reaching 500-1200kg/min), and the ejection speed has also increased to about 100. The surface treatment of shot blasting has great impact on the workpiece, the surface cleaning and strengthening effect is obvious, the shot blasting amount is large, and the efficiency is high. It is suitable for large castings and workpieces of steam turbine blades.

The steam turbine blade shot blasting machine produced by Qingdao Wozhou Machinery has high cleaning efficiency and does not require secondary cleaning. It has been praised by new and old customers. The steam turbine blade shot blasting machine produced by Qingdao Wozhou Machinery, under the premise of ensuring quality, Cost-effective for customer satisfaction.
