How to judge whether the waterjet on-off valve repair kit in the waterjet cutting head needs to be replaced?

The following is a method to determine when the waterjet on/off valve repair kit of the waterjet cutting head should be replaced:

1. Observe the water leakage

1.1 If obvious water droplets are found to be seeping out around the waterjet cutting head when it is stationary, this may be a signal that there is a problem with the water switch sealing component. In particular, there should be no water leakage when the waterjet cutting head is not working. Once a water leakage occurs, the damage of the sealing component should be considered.

1.2 During the operation of the water cutting head, if water is found to flow out from abnormal parts, such as leaking from the connection parts, shell gaps, etc., it also means that the water switch sealing component may fail and needs to be inspected and replaced.

2. Check the change in water flow

2.1 When the water flow of the waterjet cutting head is significantly reduced, and other reasons such as insufficient water source pressure and pipe blockage are excluded, it may be that the water switch sealing component is worn and the seal is not tight, causing part of the water flow to leak, thereby affecting the overall water flow.

2.2 If the water flow is unstable, sometimes large and sometimes small, it may also be that there is a problem with the sealing component and it cannot maintain a stable water flow channel.

3. Pay attention to changes in cutting effects

3.1 If the cutting accuracy of the water jet cutting head decreases and the cutting surface becomes rough and uneven, it may be due to damage to the water switch sealing component, which affects the pressure and stability of the water jet, thus affecting the cutting effect.

3.2 When the cutting speed slows down significantly and cannot be improved even after adjusting the water jet pressure and other parameters, you should also consider whether the sealing component has failed, because poor sealing may cause energy loss of the water jet and reduce cutting efficiency.

4. Regular inspection and maintenance

4.1 According to the user manual and maintenance requirements of the water jet cutting equipment, check the waterjet cutting head regularly. Generally speaking, after a certain working time or number of cutting times, even if there is no obvious sign of failure, the water switch sealing components should be checked for wear, aging, etc.

4.2 If the equipment is used in harsh working environments, such as high temperature, high humidity, corrosive environment, etc., the service life of the sealing components may be shortened and more frequent inspections and replacements are required.
