For waterjets, waterjet sand and waterjet sand tubes are all common consumables. In comparison, waterjet sand tubes are much more expensive. Under normal circumstances, the life of the waterjet sand tube is about 150 hours, but its service life often fails to reach this value due to certain factors during the actual use.
We all know that pomegranate sand is a kind of pointed sharp abrasive, and its hardness is also very large, so it will cause certain wear on the waterjet sand pipe in use. This is also one of the reasons why the water knife abrasive is not recommended to use brown corundum. Because of the greater hardness of brown corundum, the wear of the sand tube is greater, resulting in a lower life of the sand tube, and the overall cost of use is much greater than that of pomegranate sand.
Secondly, the main components of the waterjet sand tube are tungsten and zirconium. Although they are very wear-resistant materials, their service life depends on the abrasive. Taking into account the characteristics of the abrasive itself, wear on the sand tube is unavoidable.
In addition to this problem, the cleanliness of the waterjet sand also has a great influence on the quality of the waterjet sand tube, because the waterjet sand is not clean or contains too much dust not only does not have the cutting effect, but also may cause the sand tube to be scrapped. The life of the waterjet sand tube is drastically reduced, so be sure to buy less clean dust.
High-quality water-jet sands are subjected to multiple magnetic separations, screening, washing and drying, so they have stringent quality control standards in terms of cleanliness and dust and impurities so that they will not occur during their use. The problem of plugging caused by dust, large particles, etc. in the waterjet sand tube helps to prolong the service life of the sand tube.
