The working principle of the shot blasting machine is to hit the steel shot with a diameter of about 1mm to the surface of the railway fasteners to be overhauled in the form of high-speed projectile motion. While cleaning and removing rust on the surface of fasteners, a large amount of steel shot will be consumed. Sometimes equipment operators, in order to achieve strict rust removal quality, blindly increase the shot blasting time, which will not only produce a large amount of steel shot consumption, but also cause excessive cleaning and rust removal of railway fasteners, causing damage to the body structure and affecting its use Longevity, in severe cases, it will also cause the scrapping of railway fasteners.
2. Heavy workload
In order to ensure the accuracy of the inspection results, it is necessary to perform shot blasting and rust removal on railway fasteners. The workload is self-evident and has doubled. However, the shot blasting and rust removal equipment commonly used by Chinese railways has low work efficiency. Indisputable facts. In the future, the improvement of shot blasting rust removal technology must take this into account, so as to help workers improve the efficiency of rust removal and shorten working time.
With the development of the times, the maintenance process standards of railway fasteners have become more stringent. They are all trains, and relative to different models, the related train fasteners are very different, and the technical parameters are different, which brings great difficulty to the shot blasting and rust removal of vehicle parts.
The above is the relevant introduction about the difficulty of railway fasteners shot blasting. We must know that the incomplete derusting of railway shot blasting will directly threaten the operational safety of China's railways. Therefore, in the future operation process, we must strengthen prevention and repair properly to improve the quality of shot blasting and rust removal of Chinese railway fasteners.
