Sand blasting machine is the category of air conveying machinery. In the pipeline, compressed air is used to transport powdery particles (1 ~ 4mm in diameter) from one place to another. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, so as to improve the surface quality of the object.

Sand blasting machine is a kind of common casting mechanical equipment. With the wide application of sand blasting machine, some operators who are troubled by sandblasting machine failure will not be able to continue to use if they do not eliminate the fault in time. Next, Kunshan huaguanshen sandblasting machinery to share common sandblasting machine failure.

Sandblasting machine failure phenomenon: no compressed air, no abrasive

Possible causes:

1. Compressed air is not turned on.

2. The setting pressure of pressure regulating valve is too low.

3. The foot switch is not adjusted properly or damaged.

4. Sandblasting or abrasive valve clogging.

5. The safety gas path is cut off.

6. The main pressure regulating valve of sandblasting machine is broken.

7. The control pressure regulating valve is broken.

Exclusion method

1. Turn on the air source.

2. Adjust the pressure above 0.5MPa.

3. Adjust or replace the foot switch.

4. Clean nozzle or abrasive valve or reassemble.

5. Check the valve on the safety gas path.

6. Check the main pressure regulating valve of sandblasting machine.

7. Check the sandblasting machine control valve.

Sand blasting machine fault: good sand into the dust bag.

Possible causes:

1. The gap of the new vacuum bag is large.

2. The sand material is too fine

Exclusion method:

1. It can be removed after 8 hours.

2.Sand blasting machine failure: sand material leakage.

Possible cause: the vacuum bag has holes or is not clamped.

Troubleshooting: replace the vacuum bag and clamp it again.

Failure of sandblasting machine: vision is not clear when sandblasting.

Possible causes:

1. The dust bag is blocked.

2.Block the aging bag.

3. There is too much dust in sand.

4. The pressure of compressed air is too high.

Exclusion method:

1. Vibrate the dust bag of sand blasting machine.

2. Replace the dust bag of sandblasting machine.

3. Replace sand material.

4. Lower the pressure recommended by sandblasting machine.
