![]() ![]() Sometimes, if the overstroke alarm occurred in error, these steps will reset your system and resolve the problem. Monitor the intensifier stroke rate via the indicator on the operator interface or manually by monitoring the proximity switches.Turn on the pump and allow pressure to build.Regardless of whether the overstroking is to the left, right, or in both directions, the first thing you should do is reset the alarm. ![]() Sometimes, though, the hydraulic piston travels faster in one or both directions, or more than the pump can support. It is normal for the intensifier to stroke faster during startup and when changing between low pressure and high pressure however, during normal operation, the intensifier should stroke smoothly to the left and right at the same speed. Three other common problems with intensifier-based waterjet systems are hydraulic pressure failure, low water pressure, and hydraulic temperature overheating. Some of the most common problems are overstroking, water leaks, and short seal life (see Figure 1). Because it has more moving parts, more can go wrong. The intensifier is probably the hardest-working part of any waterjet system. Most of them can be quickly resolved with some simple troubleshooting. Still, as with any mechanical machinery, problems are sure to surface from time to time. Engineering advances and advanced system diagnostics that warn of a problem before it starts have made today’s waterjet systems more reliable than those designed even a decade ago, making maintenance more predictable and reducing downtime in general. The newest systems can cut faster and more precisely, and they are more reliable for improved uptime. Like other cutting technologies, waterjet systems have changed quite a bit over the past decade. That makes waterjet the preferred method for cutting metal parts for aerospace and construction applications in which metallurgical changes could impact the integrity of the material. In contrast with thermal cutting, they can precisely cut metal without leaving a heat-affected zone (HAZ). ![]() High-pressure waterjets are a versatile alternative to cutting methods such as plasma, laser, and mechanical slitting machines. Problems can be avoided or resolved with simple troubleshooting. Still, they need maintenance and repair from time to time. High-pressure waterjets have advanced substantially over the years in terms of longevity and reliability. ![]()
