In a high-pressure sandblasting environment, Sandblasting barrel parts are subjected to complex and diverse forces, which have a crucial impact on the performance, life of the parts and the stable operation of the entire sandblasting equipment.
First, the impact force of the sandblasting medium is the main force on the parts. When the high-pressure gas carries the sand particles and sprays out at high speed, the sand particles hit the inner wall of the sandblasting barrel, the nozzle and other parts at a very high speed. The magnitude of this impact force is closely related to factors such as the sandblasting pressure, the hardness and particle size of the sand particles and the spraying angle. For example, when the sandblasting pressure is high and the hardness of the sand particles is high, the instantaneous impact force on the surface of the part can reach a considerable value, which may cause wear, deformation and even partial damage to the surface of the part. For the nozzle, its front end directly faces the sand particle flow, and the impact force it bears is particularly concentrated, and it needs to have sufficient strength and hardness to withstand this high-frequency strong impact.
Secondly, the parts are also subjected to the effect of internal pressure. Since the sandblasting barrel is in a high-pressure state during the sandblasting process, the barrel wall and related connecting parts need to withstand pressure from the inside to the outside. This pressure acts evenly on the barrel wall, requiring the barrel wall material to have good pressure resistance to prevent the barrel from breaking or deforming. At the same time, parts such as valves and pipe connections must ensure sealing performance while bearing internal pressure. Once the pressure causes the seal to fail, the sandblasting process will not be able to proceed normally, and even cause safety accidents.
Furthermore, vibration and friction are also factors that cannot be ignored. During the sandblasting process, the vibration generated by the high-speed flowing sand and gas will be transmitted to the Sandblasting barrel parts. Long-term vibration may cause problems such as loose connections and fatigue damage of parts. The friction generated by sand particles passing through pipes, nozzles and other parts will gradually wear the inner wall surface of the parts, reduce the dimensional accuracy and surface quality of the parts, and thus affect the sandblasting effect and equipment life. For example, the inner wall of the sand tube may become thinner after being subjected to sand friction for a long time, resulting in a decrease in pressure resistance and even sand leakage.
Finally, in order to ensure that the Sandblasting barrel parts can work stably and reliably in a high-pressure sandblasting environment, these stress conditions need to be fully considered during the design and manufacturing of parts. By selecting suitable materials, such as high-strength alloy steel, wear-resistant ceramic materials, etc., optimizing the structural design of parts, adding reinforcing ribs, improving the connection method, etc., and using advanced surface treatment technology to improve the wear resistance and corrosion resistance of parts, the comprehensive performance of parts is improved, their service life is extended, and the efficient and safe sandblasting operation is guaranteed.
