Shot Blasting on a LiBr Absorption Unit
Shot blasting operates on the principle of using an electric motor to drive an impeller, which in turn rotates at high speed. This rotation generates centrifugal force, causing projectiles—typically cast steel shot, steel wire cut shot, stainless steel shot, or other materials—ranging in diameter from about 0.2 to 3.0 mm, to be ejected toward the surface of the workpiece. The high-velocity impact of these projectiles creates a controlled level of roughness on the surface of the workpiece. This process is commonly used for cleaning, strengthening, or preparing surfaces in various industries, improving their quality and performance.
The role of shot blasting in the maintenance and enhancement of LiBr absorption units includes:
- Initial Cleaning of the LiBr Absorption Unit Surface
Shot blasting is used to clean the surface of the LiBr absorption unit by removing oxidized skin, surface rust, and any adhering sand. Additionally, it helps identify any surface defects, ensuring that potential issues are detected early. Moreover, shot blasting improves the surface finish of the unit, which enhances the adhesion of the paint applied during subsequent painting processes, leading to better corrosion resistance and a more durable finish. - Reinforcement of the LiBr Absorption Unit as a Whole
Shot blasting plays a key role in strengthening the LiBr absorption unit by altering the welding tensile stress to compressive stress. This process helps to reduce the risk of surface cracks and increases the overall durability and service life of the unit, making it more resistant to wear and tear during its operational life.
