Reason 1: The sand in the blasting bucket has run out

Troubleshooting method: After the pressure barrel is degassed, sand can be added again.

Cause 2: The nozzle is blocked by a foreign object

Troubleshooting method: After shutting down the machine and unloading the air, first turn off the sandblasting nozzle cover to check whether the sandblasting nozzle is blocked by foreign objects. If there is, remove the foreign objects.

Reason 3: The pipe is blocked by foreign objects and excessive sand materials

Troubleshooting method: After shutting down and discharging the air, first turn down the sandblasting nozzle, then inflate the sandblasting bucket, then open the thrust bucket and use air pressure to blow out the sand and foreign objects in the tube. If not, the tube needs to be removed for cleaning or replacement.

Reason 4: Adding wet sand (water vapor or rainwater into the sandblasting bucket) causes the sand adjuster mouth to be blocked.

Troubleshooting method: first remove the nozzle (or remove the sandblasting pipe), push the force valve fully close, fully open the sand conditioner, and then fully open the intake valve to allow the air to harden the wet sand in the barrel squeeze out. While pushing out the wet sand in the half barrel, the thrust is instantly fully opened and fully closed to assist in cleaning the wet sand in the tube. If this is ineffective, only remove the sand adjuster at the bottom of the sand bucket, unload the sand, and then lock the sand adjuster back. in the barrel.

Reason 5: The high-pressure air instantly sends a large amount of water into the barrel, causing the sand in the barrel to be wet, or the water is sucked into the sandblasting pipe through the thrust valve, causing the pipe wall to be wet and sticky, thus causing blockage

Troubleshooting method: In addition to the above troubleshooting methods, it is better to install a freeze dryer.

Reason 6: The sand is not filtered, so that large foreign objects enter the sandblasting bucket and get stuck on the sand conditioner, causing blockage and unable to produce sand

Troubleshooting method: only remove the sand conditioner at the bottom of the sand bucket, unload the sand, and then lock the sand conditioner back. Can.
