Example Embodiment
[0014] See figure 1 , Example 1: A sandblasting process for the head of an aviation fire extinguishing bottle includes the following steps:
[0015] a. Pretreatment: inspect the sandblasting machine, air compressor and sandblasting nozzle 2, and pass 0.5MPa compressed air to the air compressor;
[0016] b. Sandblasting: sandblasting the head of the fire extinguishing bottle to remove the oxide scale, welding slag and oil stains on the fire extinguishing bottle. Set up baffles 1 on both sides of the sandblasting nozzle 2. During the sandblasting process, the sandblasting nozzle 2 moves slowly , And the fire extinguishing bottle rotates at a constant speed of 1 revolution per minute;
[0017] c. Cleaning: Blow out dry compressed air through an air compressor to clean the sand and ash on the surface of the head of the fire extinguishing bottle;
[0018] d. Inspection: Inspect the surface roughness of the head of the fire extinguishing bottle. The head should have a uniform roughness...
Example Embodiment
[0019] Embodiment 2: A sandblasting process for the sealing head of an aviation fire extinguishing bottle includes the following steps:
[0020] a. Pretreatment: inspect the sandblasting machine, air compressor and sandblasting nozzle 2, and pass 0.55MPa compressed air to the air compressor;
[0021] b. Sandblasting: sandblasting the head of the fire extinguishing bottle to remove the oxide scale, welding slag and oil stains on the fire extinguishing bottle. Set up baffles 1 on both sides of the sandblasting nozzle 2. During the sandblasting process, the sandblasting nozzle 2 moves slowly , And the fire extinguishing bottle rotates at a constant speed of 2 revolutions per minute;
[0022] c. Cleaning: Blow out dry compressed air through an air compressor to clean the sand and ash on the surface of the head of the fire extinguishing bottle;
[0023] d. Inspection: Inspect the surface roughness of the head of the fire extinguishing bottle. The head should have a uniform roughness wi...
Example Embodiment
[0024] Embodiment 3: A sandblasting process for the head of an aviation fire extinguishing bottle includes the following steps:
[0025] a. Pretreatment: inspect the sandblasting machine, air compressor and sandblasting nozzle 2, and pass compressed air of 0.6MPa to the air compressor;
[0026] b. Sandblasting: sandblasting the head of the fire extinguishing bottle to remove the oxide scale, welding slag and oil stains on the fire extinguishing bottle. Set up baffles 1 on both sides of the sandblasting nozzle 2. During the sandblasting process, the sandblasting nozzle 2 moves slowly , And the fire extinguishing bottle rotates at a constant speed of 3 revolutions per minute;
[0027] c. Cleaning: Blow out dry compressed air through an air compressor to clean the sand and ash on the surface of the head of the fire extinguishing bottle;
[0028] d. Inspection: Inspect the surface roughness of the head of the fire extinguishing bottle. The head should have a uniform roughness with a r...
