If you need to replace anything on your waterjet maching, you are in luck. In general, waterjet parts are easy to find and replace, making maintenance a hassle-free venture. This is very different from many other machines and can be a huge benefit to anyone who needs replacements.
A waterjet uses high-pressured water to concentrate a lot of pressure and energy onto a very small area. The result is a very precise cut. If anything goes wrong with your waterjet machine, you will likely need to get new parts. The typical waterjet parts that will need replacement and upkeep are the orifices (or jewel) and the nozzles.
Generally, it is a component of the nozzle that wears first and will need ongoing replacement. There is quite a large difference between pure waterjet nozzles and abrasive waterjet nozzles, so it is important that you always make sure you are ordering and replacing the part that matches with the appropriate machine. This is why it is useful to go directly to a waterjet parts supplier rather than ordering second-hand from a third-party dealer.
A pure waterjet nozzle directs the high-pressure water through the orifice to cut the material. This means there is no mixing tube. If something needs replaced, it is most often the jewel. Overtime, dirty inlet water can cause cracking and plugging, but can be avoided with a proper filtration system. Jewels are inexpensive and easy to replace.
For an abrasivejet nozzle, the mixing tube is prone to wear and tear and may require some maintenance or occasional replacement. Typically, most of your ongoing maintenance costs will come from replacing these parts due to normal wear and tear. The controller is the main interface that operates the waterjet. This and the water pump may need to be replaced after they have been used regularly and for a long time.
The catch tank is another important part on a waterjet. This is where all the excess and water and abrasive bits collect. Because waterjets are environmentally friendly, this excess water can be easily disposed of in the sewer system. To maintain the cleanliness and overall function of the machine, the bits will need to be periodically shoveled out. Fortunately, they are completely safe for landfills.
