一、Common causes and solutions for automatic glass sandblasting machine not producing sand
1. Add too much sand
It is blocked and cannot be pressurized. Solution: The amount of sand added should be appropriate, not too much. The spray gun is blocked. Solution: After stopping the air, remove the nozzle to see if there is any foreign body. If there is a foreign body, just clean the foreign body;
2. Sand pipe plugging
Solution: After stopping the gas, remove the nozzle, dry the sandblaster, and blow out the foreign matter with high-pressure gas. If it does not work, you have to remove the pipe for cleaning or replacement;
3. Wet sand
4. Solution: Clean the nozzle of the spray gun, and dry the sand to filter. There is no filter screen, causing large foreign matter or uneven sand to enter the sand valve. Solution: Open all sand control valves, and use forced air to remove foreign objects or agglomerated sand materials. If this does not work, you can only release the sand, filter it again, and add it. Too little sand. Solution: Turn off the sandblasting machine and air source, and add sand;
5. How to protect the automatic glass sandblasting machine
6. The equipment should be placed in a ventilated and well-lit workshop. It is best to install a dust-absorbing and moisture-absorbing sponge on the heat dissipation holes of the equipment, and the sponge should be replaced frequently. The equipment can be waterproofed, such as spraying, dipping, potting and other processes can enhance the moisture-proof function of the equipment. Choosing electronic components and materials with low hygroscopicity can minimize the equipment from getting damp. If you don't use the equipment frequently, put it in a dry place, put a desiccant, and cover it with a protective cover. If you encounter the rainy season and other humid seasons, you can use the color-changing silica gel desiccant, and the desiccant should be replaced frequently. The equipment should be cleaned and organized to ensure the cleanliness of the equipment and its working environment.
二、 Failure analysis of automatic glass sandblasting machine
During the operation of the automatic glass sandblasting machine, its internal parts have to withstand various effects such as force, heat, friction, and wear. As the use time increases, its operating status will continue to change, and some performance will gradually degrade, resulting in Failure of parts (components). This is the main reason for the failure of the glass sandblasting machine. Therefore, studying the failure mechanism of parts (components) and identifying the failure mode is the main task of ensuring diagnosis. It is also the foundation of information for fault diagnosis and ultimately reducing the life cycle cost of equipment Purpose; fault analysis (failure analysis) is the main component of diagnostic theory.
