Common problems of water jet cutter - troubleshooting of low water pressure

After a long time, no matter how good the water jet cutter is, it may encounter various problems. What makes users scratch their ears and annoy their cheeks is that the water pressure becomes low, which seriously affects the cutting efficiency. It is not a big problem that must be repaired. This kind of problem can be solved by troubleshooting or replacing accessories to restore the due cutting efficiency of the water jet.
1. High pressure water leakage
After the high-pressure water comes out of the check valve, observe whether the high-pressure pipe or joint leaks. Once it leaks, the cutting effect will be greatly reduced. In case of leakage, replace the high-pressure pipe fittings or connectors in time.
2. Insufficient water supply
Check whether the water supply system is perfect. If the water supply is insufficient to meet the requirements, the cutting capacity will also be low. Insufficient water supply may also be caused by incomplete opening of the water valve or clogging of the filter screen, or the filter has not been replaced for too long and filtering is slow.
3. Turbocharger piston oil seal damaged and leaking
The supercharger is the main place to provide high pressure. It is sealed and compressed through the seal ring. If the seal ring is slightly damaged, the pressure will be reduced to a certain extent. Judge whether there is oil stain on the surface from the outside, or remove and observe whether the sealing ring is deformed or enlarged.
4. The water outlet of sand pipe and nozzle is too large
Both the sand pipe and nozzle will be nibbled by water jet cutting. The final result is that the water outlet is too large and the water column cannot be cut centrally. In this case, either rotate the sand pipe and nozzle angle to see if the water can be concentrated, or you can only replace it directly.
5. Sand pipe and nozzle are not installed correctly

The water jet is cut vertically. If the gem/sand pipe is not installed correctly, the water jet will directly shoot at the inner wall, causing the inner wall to become pitted. The most important thing is that the water will form a backflow when blocked, which will counteract the previous water impact, and eventually lead to low cutting ability.
