The water jet cutting head is an important part of the waterjet. It passes high-pressure water through the nozzle to form a high-speed water jet to cut the material. The maintenance of waterjet cutting head mainly includes the following aspects:

Regularly check the wear of the nozzle and replace the nozzle in time. The wear of the nozzle will affect the quality and cutting effect of the water jet, and it is generally recommended to replace the nozzle every 200-300 hours of use.

Regularly check the wear of the sand tube and replace the sand tube in time. The wear of the sand tube will affect the transportation and mixing of the abrasive. It is generally recommended to replace the sand tube every 100-200 hours of use.

Regularly clean the impurities inside the cutting head to prevent clogging and corrosion. There may be scale, abrasives, metal shavings and other impurities inside the cutting head, which should be cleaned with water or air at regular intervals.

Regularly check the seal of the cutting head and replace the seal in time. The seal of the cutting head will be aged or damaged due to the impact of high-pressure water, resulting in leakage or backwater of the water jet. The state of the seal should be checked at regular intervals, and the seal should be replaced as needed.

Regularly check the alignment of the cutting head and adjust the alignment in time. The centering of the cutting head refers to whether the centerlines of the nozzle and the sand pipe coincide. If not, it will affect the stability and cutting quality of the water jet. It should be checked and adjusted with a centering tool at regular intervals
