1. Gem nozzle
Observe the flow of water from the jewel nozzle and turn it on at low pressure. The water flow should be symmetrical, and its width depends on the type of nozzle used; the ruby and sapphire nozzles have a slightly wider stream of water, and the diamond nozzles have a narrower stream of water and are more consistent. If the water flow starts to widen, the nozzle is damaged and it should be replaced immediately. Damaged nozzles (or misaligned pipes) can cause internal damage to the cutting head.
2. Cutting head
Periodically inspect the cutting head for signs of wear or damage. For example, accidental contact of the sand tube with the clamp can damage the nozzle nut and internal parts that hold the mixing tube in alignment.
3. Blade head sand supply system
Periodically inspect and replace consumable parts of the conveyor system, such as pipes and fittings, to ensure that no parts of the sand supply system below the bottom of the mini-hopper are exposed to air. To perform this check, disconnect the sand transfer line from the joint at the bottom of the micro funnel, manually open the jet and place the thumb on one end of the sand transfer line. You will feel a sufficient (but not excessive) vacuum present, which may allow The tip of the thumb produces a depression. Inadequate vacuum may indicate that the entrance to the cutting head is blocked or there is a crack in the sand transfer line and must be resolved to fully utilize the efficiency of the system.
Checking the system and keeping it in the best operating condition will make waterjet cutting operations more efficient and extend the life of its components.
4 machine vertical and cross beams
Use the manual function of the computer to move the vertical and horizontal beams to confirm that the vertical and cross beams do not have abnormal noise.
