1. The sand material in the sand blasting barrel has been used up, method of elimination: after unloading the gas from the pressure barrel, add sand again.
2. The nozzle is blocked by foreign matter troubleshooting method: after shutting down the machine and unloading the gas, first turn down the nozzle set and check whether there is any foreign matter blocking the nozzle, if there is any foreign matter, just remove it.
3. The tube is blocked by foreign matter and excessive sand material Troubleshooting method: After shutting down the machine and unloading the air, first turn down the sand blasting nozzle, inflate the sand blasting barrel, and then open the thrust barrel to utilize the air pressure to blow out the sand material and foreign matter in the tube. If not, you need to remove the tube to clean or become new.
4. Add wet sand material (moisture or rain into the sand blasting barrel) caused by the sand adjuster mouth sand material blockage. Troubleshooting methods: first remove the nozzle (or remove the sandblasting pipe), the thrust valve is fully closed, the sand regulator is fully open, and then the air inlet valve is fully open, so that the gas will be the wet sand inside the barrel hard to squeeze out. Half a barrel of wet sand out of one side, while the thrust instantaneous full open and full closed to assist in cleaning up the wet sand in the tube. If this is ineffective, only the bottom of the sand bucket sand regulator removed, the sand out, and then lock the sand regulator back, and then, the sand material to get dry again, sifted through the screen, in the re-added to the sand bucket can be.
5. High-pressure air instantly sent into a large amount of moisture caused by the barrel of sand material wet, or through the thrust valve will be the moisture sucked into the sand blasting tube caused by the wall of the tube wet sticky sand, thus causing obstruction fault troubleshooting method: In addition to the above method of elimination of the operation, it is very good to install a freeze dryer.
6. Add sand without filtering and make large foreign objects into the sand blasting barrel stuck in the sand regulator, causing blockage, unable to sand troubleshooting methods: only the bottom of the sand barrel sand regulator removed, the sand discharged, and then the sand regulator lock back, and then the sand through the filter screen, and then re-added to the sand barrel can be.
