To determine whether Sandblasting barrel parts are worn and need to be replaced, a comprehensive consideration is needed from multiple aspects.
First, a preliminary judgment can be made through an intuitive appearance inspection. Observe whether there are obvious scratches, dents, cracks or deformations on the surface of the parts. If deep scratches or large areas of wear marks appear on the surface of the parts, this may be a sign of wear.
Second, pay attention to the dimensional changes of the parts. Use precise measuring tools to compare the current size of the parts with the original design size. If the dimensional deviation exceeds the allowable range, it may affect the normal working performance of the sandblasting barrel, indicating that the parts are worn.
It is also important to check the connection parts of the parts. For example, at the threaded connection, if the threads are worn, stripped or loose, it may cause a loose connection and affect the overall performance of the sandblasting barrel.
Observing the surface roughness of the parts is also a method. Under normal circumstances, the surface of the parts should be relatively smooth. If the surface becomes rough and loses its original finish, it may mean that the parts have been excessively worn during the sandblasting process.
In addition, pay attention to the working efficiency and effect of the parts. If the sandblasting effect of the sandblasting barrel is not as good as before, such as uneven sandblasting, weakened force or reduced efficiency, this may be due to wear of the parts.
Changes in the material of the parts can also provide clues. For example, the originally hard material becomes fragile and prone to breakage or peeling, which is likely to be due to material degradation caused by long-term wear and fatigue.
It can also be judged by sound. When the sandblasting barrel is working, if the parts make abnormal noise, vibration or friction sounds, this may be a problem with the fit between the parts, suggesting that the parts are worn.
Take the spray gun of the sandblasting barrel as an example. If the nozzle diameter of the spray gun becomes larger due to wear, the sand particles sprayed will be dispersed, and the expected sandblasting effect cannot be achieved, and the consumption of sand will also increase.
For example, if the impeller blades of the impeller inside the sandblasting barrel are worn, it may cause unbalanced rotation, abnormal vibration and noise, and also reduce the efficiency of sandblasting.
In summary, judging whether the Sandblasting barrel parts are worn requires a combination of appearance inspection, size measurement, work effect observation, sound analysis and other methods. By combining these judgment bases, it is possible to more accurately determine whether the parts are worn to the extent that they need to be replaced, so as to ensure the normal, efficient and safe operation of the sandblasting barrel.
