What is the difference between the movable steel plate, steel bridge shot blasting machine and sand blasting machine?
Mobile steel plate, steel bridge beam shot blasting machine and sand blasting machine are both used as surface rust removal and roughening cleaning equipment, which are actually different. However, many people may have doubts about the difference between these two equipment at the initial stage?
1. Due to different power, the shot blasting machine for moving steel plate and steel bridge beam uses electric drive impeller to run at high speed to impact the shot blasting to the work site
To finish the process of surface derusting, cleaning and strengthening; For sand blasting, compressed air is selected as the power source. When working, compressed air carries sand (carborundum, corundum, glass sand, etc.) to impact the workpiece surface and complete the operation;
2. Different shot blasting and sand blasting materials are selected. The mobile steel plate and steel bridge beam shot blasting machine uses specially made materials and shaped metal particles as the shot blasting medium, while the sand blasting machine uses glass sand, corundum, carborundum and other high hardness wear-resistant materials;
3. After shot blasting or sand blasting, the surface hardness obtained is different. The moving steel plate and steel bridge beam shot blasting machine has the effect of surface hardening, but the sand blasting machine is out of reach;
4. The cleaning efficiency is different. The moving steel plate and steel bridge beam shot blasting machine has high cleaning efficiency, low cost, few operators, and is easy to realize mechanization, which can greatly save labor costs; The cleaning efficiency of sand blasting machine is relatively low, with many operators and high labor intensity;
5. The moving steel plate and steel bridge beam shot blasting machine does not use compressed air to accelerate the shot, so it is not necessary to set a high-power air compression station, and the cleaned surface is free of moisture; The sandblasting machine must be equipped with a high-power air compression station. Under the same cleaning effect, the energy consumption is large; The cleaned surface is prone to moisture and rust regeneration;
6. There are relatively many vulnerable parts of the moving steel plate and steel bridge shot blasting machine, especially the parts such as blades, which wear quickly and need to be replaced constantly; Sand blasting machine has simple equipment structure, less investment in the whole machine, less vulnerable parts and low maintenance cost;
7. The steel plate and steel bridge beam shot blasting machine is easy to move, and is widely used in flat and vertical workplaces; The sandblasting machine is easier to clean the inner and outer surfaces of complex workpieces and the inner walls of pipe fittings, and is not limited by the site. The equipment can be placed near the oversized workpieces;
