The influence on the service life of waterjet abrasive nozzle?

For water jet, abrasive and abrasive nozzle are common consumables, and the price of abrasive and abrasive nozzle is much higher than that of water jet. Under normal circumstances, the service life of the abrasive nozzle is about 150 hours, but in the actual use process, due to the influence of some factors, its service life often does not reach this value.

We all know that pomegranate abrasive is a kind of abrasive with sharp corners and great hardness, so it will cause certain wear to abrasive nozzle of water jet in use, which is one of the reasons why brown corundum is not recommended for water jet abrasive. Because the hardness of brown corundum is greater and the wear of abrasive nozzle is greater, the service life of abrasive nozzle is lower, and the whole use cost is far greater than that of pomegranate abrasive.

Secondly, the main components of the water jet abrasive nozzles are tungsten and zirconium. Although they are very wear-resistant materials, their service life should also be determined according to the abrasive in use.

In addition to this problem, the cleanliness of the water jet abrasive also has a great impact on the quality of the water jet nozzle, because the water jet abrasive is not clean or contains too much dust, which not only has no cutting effect, but also may cause the scrap of the nozzle, so the service life of the water jet nozzle will be sharply reduced, so we must buy a clean abrasive nozzle with less dust.

The high-quality water jet nozzle has been magnetic separation, screening, washing and drying for many times, so there are strict quality control standards in terms of cleanliness and dust impurities, so that the plug problem caused by dust and large particles in the water jet nozzle will not appear during its use, which helps to prolong the service life of waterjet cutting system.
