How's about the service life of the waterjet on off repair kit?

The life of the waterjet on off valve repair kit in the waterjet machine will vary depending on a variety of factors:

Generally speaking, if it is used and maintained normally, the waterjet on off valve repair kit can be used for one month to several months. However, if the following situation occur, its life may be shortened:

I. Working Environment Factors

1. Poor water quality: If the water contains a large amount of impurities, particulate matter or corrosive substances, it will accelerate the wear of parts such as seals, thereby shortening the life of the repair kit. For example, some industrial water may contain rust, sand etc. These impurities will continuously impact and wear the sealing components when the water flows through the waterjet on off valve repair kit.

In order to deal with this situation, we have equipped some customers with our water filtration system. After the water used by the machine is filtered through the water filtration system, the sediment, calcium and magnesium ions in the water can be effectively filtered out, greatly extending the service life of related water sealing parts.

2. High temperature environment: If the waterjet machine works in a high temperature environment, the material of the waterjet repair kit may be affected by thermal expansion and contraction, resulting in a decrease in sealing performance and a shortened life. For example, if the waterjet equipment is used in some high-temperature workshops or near heat sources, the life of the repair kit may be greatly affected.

II. Frequency and intensity of use

1. High frequency of use: If the waterjet machine runs continuously for a long time or starts and stops frequently, the wear of the waterjet on off valve repair kit will accelerate. For example, in some large processing plants, such as Antolin and Pelze etc. the automotive interior cutting processing line, the waterjet cutting equipment runs almost all day, and the life of the repair kit may be significantly shortened. What we got from our client, that some of the waterjet on off valve repair kits run about 50k cycles until it need to be replaced. That's very good performance.

2. Higg-intensity cutting: When high-intensity cutting tasks require high-pressure water jets, the pressure on the waterjet on off valve repair kit will also increase, which will accelerate the fatigue and damage of the seal and reduce its life.

III. Maintenance

1. Lack of regular maintenance: If regular inspections and maintenance are not performed, such as cleaning impurities around the on off valve repair kit of waterjet head parts and checking the wear of the seal, the life of the repair kit will be affected. For example, long-term non-cleaning may cause impurities to accumulate and damage the sealing components.

2. Improper installation: If the repair kit is installed improperly, such as uneven installation of the seal and uneven tightening force, it will affect the sealing performance and service life of the repair kit. Some waterjet spare parts require special tools for installation. Using professional waterjet tools for disassembly and assembly can not only increase the speed of installation, but also ensure the quality of installation and prevent damage to other related parts.

In general, there is no fixed specific length of time for the life of the waterjet on off valve repair kit. It needs to be judged and maintained according to actual usage to ensure that it can work properly and extend its service life.
