What is the Proper Way of Cleaning the Abrasive Tube of Water Jet Cutter?

Every once in a while, as you use your water jet cutter, the clear tube that supplies the abrasive particles to the head gets clogged. When this happens, it causes your waterjet system to cease cutting/slicing through your material.

The usual reason for this garnet flow malfunction is due to water finding its way into the tube, which needs to remain dry so that garnet particles can flow unhampered. 

Water jet cutting machine operators can clean out the tube on their own just so the project flow can remain sustained.  To clean the abrasive tube for your water jet cutter, we suggest that you follow the recommended steps we have below. 

Always use your goggles and gloves in doing so. They are your proper protective gears to use in carrying out tasks like this.

Inspect the line and detach the abrasive tubes. 

The translucent tube that connects to the side of the water jet nozzle head is known as the abrasive tube. This long tube is connected to the print head by a smaller 2-3 inch translucent tube. Pull those free carefully so that the short tube does not fall into the water jet pool. Stop if any of the tubes are missing or broken. 

The hopper, which is usually attached next to the waterjet head, is then to be inspected. A tiny garnet feeder can be found right at the bottom of the hopper, connected to the other end of the abrasive tube. Remove the abrasive hose. You can do this by removing the transparent tube from the bottom of the garnet feeder. 

Clean the tubes.

You should vacuum out leftover water or abrasive particles that have been trapped in the abrasive tubes now that they have been disconnected. Insert the compressed air gun into the end of the abrasive tube at the hopper end. 

Air can be forced into the tube by virtue of a compressed gas lever. It helps if a second person will hold the other end of the abrasive tubing and direct it away from any people into the rear of the water jet.


This will help make sure that the abrasive tubing will not dip back into the water, so that it will remain dry, and that you do not spray someone with air and filthy water jet water.  

You can now blast the narrow transparent tube that links the head to the abrasive tube. See to it that no abrasive or water is thrown back into the tank and that all abrasive particles and water are removed, both externally and internally.

Connect back your clean abrasive tubes

First, insert the narrow 2-inch tube back into the hole from which it was inserted. This is situated on the water jet head side. Next, you need to slip the long abrasive tube across the narrower tube, covering as much of it as possible.

Reattach the hopper feeder to the abrasive hopper. Do so by pressing it through the cavity right at the bottom part of the hopper.  You need to assemble this vertically at the hopper’s base. Then put back in place again the abrasive tube’s other end in its proper location which is at the bottom section of the hopper feeder.

Resume your cutting/material slicing work. 

You would almost certainly need to reverse the head’s location by clicking the backward button next to the print to complete your cut. The head will retrace the cut course. If you hit a point directly above a previously cut part, you can resume the cut.

As long as you have your water jet cutting machine tubes properly cleaned, the cutting/slicing job you are working on previously can be resumed without further ado.
