How to avoid the plugging phenomenon of garnet sand？
Since garnet sand has been used in industry, it has been used in more and more fields, especially in the waterjet cutting industry. Garnet sand has become one of the most used abrasives for water cutting. It is used in glass parquet, cutting, stone parquet cutting, etc. More. At the same time, there are more and more garnet sand manufacturers on the market, and the quality of garnet sand is also uneven. If you choose inferior manufacturers, there will be blockages during water cutting operations. The following editor will explain to you How to avoid these problems
Garnet sand
1. Look at the negative pressure gauge
If the negative pressure is significantly lower than the set value, there may be impurities accumulated in the throttle end of the nut at the outlet of the sandbox. In this case, you directly open the nut of the welded pipe joint, put down the sand control valve, and then use a screwdriver to remove the throttle valve seat. Generally, impurities will flow out with the garnet sand. But if it still does not work, it may be due to too much or too large piles of debris, which makes you need to remove the sandbox to remove the debris.
2. Observe that the negative pressure gauge has no negative pressure
In this case, foreign matter or excessive garnet sand accumulates between the sand control valve body and the sand pipe joint. In this case, the removal procedure is more complicated. It is necessary to remove the sand valve joints, sand pipes, and sand pipe joints one by one, and then clean them with high-pressure gas, so that the debris can generally be removed and normal use can be restored.
