Nowadays, shot blasting machine has been used in all walks of life and various professional fields. However, due to improper use or purchase of inferior products produced by illegal merchants, the shot blasting cleaning machine may catch fire. Today, Xiaobian talks about the reasons for the fire of shot blasting cleaning machine. Wear parts of shot blasting machine Different from shot peening machine, it is used to reduce the fatigue life of parts, increase different surface stresses, increase the strength of components, or prevent fretting. Shot blasting machine accessories Casting equipment for cleaning or strengthening the surface of castings by high-speed projectiles thrown by shot blasters. The shot blasting machine can sand, core and clean the casting at the same time. Some areas are also known as sanding machine, sand blasting machine. Vulnerable parts of shot blasting machine It is a kind of treatment technology that the steel sand and steel shot are thrown and impacted on the surface of material objects at high speed by shot blasting device. Compared with other surface treatment technologies, it is faster and more effective, and can be used for the casting process after partial retention or stamping.
Causes of shot blasting machine fire:
1. The distance between shot blasting machine and dust remover is too short, or it is mainly because we have not set a bend for the dust removal system pipeline, such a kind of dust with sparks will directly go to the filter cartridge and cause fire.
2. It is very likely that the shot blasting machine will catch fire. The dust concentration in the cleaning room of the shot blasting machine is relatively high. In addition, there may be combustible materials such as putty and aluminum magnesium powder in the dust. If the combustible materials in the dust reach a certain degree, it is very likely to cause fire or even explosion.
3. The other is that when the pipe of the dust remover of shot blasting machine is designed, the grid plate required inside prevents the direct economic entry of dust, which greatly increases the contact of some reactants to the material surface. Even if it is non flammable material, at this time, it will develop rapidly for oxidation, and the external behavior is through combustion or explosion.
