First of all, the work of the water jet mainly depends on the movement of the CNC cantilever or gantry to drive the movement of the cutting head to complete some patterns. Therefore, people are not allowed to get close to the CNC cantilever to avoid accidental injury, and the presence of interference around the cantilever should also be avoided. The water cutter head is the outlet of high-pressure water, which acts directly with the material when cutting. Therefore, it is necessary to ensure that the cutting material has been placed flat, otherwise the cutting sand pipe is easy to be damaged, which will lead to high-pressure water leakage and personal injury.

After finishing the processing, the high-pressure water switch must be turned off oenguebnci or the high-pressure water switch must be turned off before reclaiming. In case of emergency power failure, the high-pressure water will remain in the high-pressure system. Once the power is on, the residual high-pressure water will be ejected. Therefore, do not get close to the cutting head at this time. After the power is re connected, the residual high-pressure water needs to be removed.

Secondly, to ensure the safety of high-pressure pipeline. Generally speaking, the high-pressure pipe and supercharger will not have any problems. The main problem is the leakage of high-pressure water. Therefore, it is necessary to replace the sealing components at intervals according to the instructions. At the same time, choose a reasonable water cutting method, pay attention to whether there is high-pressure water seepage, once found, immediately press the emergency stop button to stop the high-pressure system. In addition, the cooling of high-pressure system is also worthy of attention. When the high-pressure system works, high temperature will be produced by hesitating pressurization and friction. If effective cooling is not carried out, the service life of the sealing components and various high-pressure components will be impressed. With long-term high temperature, the service life of the high-pressure system will be greatly reduced, and it is very easy to cause danger. Therefore, some products are equipped with high-temperature protection function, which exceeds the design value When the temperature is fixed, the system will stop automatically to ensure safety. If there is no temperature protection function, users need to pay attention to the temperature change of the equipment in case of accidents.

Finally, water knives are generally provided with high-pressure range of use. The pressure of the water jet is adjustable. If the rated high pressure 300 MPa water jet works at full load for a long time, the wear of the water jet will be great. Generally speaking, when the thickness of 2 cm steel plate is 260 MPa, the ideal speed and effect will be achieved
