The fluid power industry significantly depends on hydraulic systems that make the best use of hydraulic fluids to ensure smooth operation and effective system pressure. However, these systems are often subject to hydraulic problems that operators struggle to resolve immediately. Here are three common hydraulic issues and some ways to deal with them.
Unusual Noise
Hydraulic systems are often subject to abnormal noise levels. These unusual noises are often an outcome of two processes, including cavitation and aeration. When a pumping system aerates, the hydraulic fluid inside it begins to degrade with rapid acceleration.
Frequent cavitation and aeration put the hydraulic system at significant risk of system damage resulting from overheating, seal burns, and loss of lubrication. Therefore, the ideal way to deal with this issue is by ensuring that the system’s intake lines are tightened adequately and well-maintained.
Taking care of the fittings around your system can prevent them from weakening and becoming porous. Furthermore, it’s also essential to monitor fluid levels and fill them frequently if the reservoirs seem empty.
High Fluid Temperature
Another common hydraulic issue many plant operators face is extremely high fluid temperatures. When the fluid temperatures exceed 82°C, the system is highly likely to experience seal damage and instant fluid degradation.
Fluid temperatures rise due to two reasons, including the practice of reducing the pump’s capacity to distribute heat evenly or increasing the overall heat load. Nevertheless, it’s critical to always operate systems below 82°C to ensure the system components’ safety.
Slow Operation
Another most common machinery problem is performance reduction, which two primary factors can cause. These include slow operation and extended cycle times.
An excellent way to combat this issue is to identify potential leakages using infrared thermometers and hydraulic flow-testers to determine the source of the defect.
