Hydraulic systems are often used in a variety of applications, from construction equipment to trucking systems. Hydraulic valves play a crucial role in controlling fluid flow and pressure within these systems.
However, like any mechanical component, they can develop issues over time, impacting the entire system's performance. Hydraulic valve issues can account for about 25% of system malfunctions we fix here at EGO. Regular maintenance and inspection can help prevent these problems.
Let's look at hydraulic valves and some of the common problems with them, along with some practical troubleshooting methods we use to restore them.
Leaky Valves
Hydraulic valves may experience leakage, one of the most prevalent issues affecting performance. Leakage can arise from numerous factors, such as damaged seals, worn-out gaskets, or improperly fitted components.
A leak not only wastes hydraulic fluid but also reduces system pressure, leading to inefficiencies. To address this, we start by inspecting the valve’s seals and gaskets for damage or wear. We'll replace them if necessary. During inspections, we ensure all connections are secure and correctly torqued, preventing fluid from escaping.
Regular inspection and maintenance can significantly reduce the chance of leakage, keeping your hydraulic system running smoothly. Swing by our Tampa shop today, or we can service your machine on-site.
Valve Sticking
This is when the valve fails to move smoothly. It can result from contamination within the hydraulic fluid or corrosion on the valve surface. Such conditions create friction, preventing smooth operation, which can lead to improper fluid flow and pressure control.
Cleaning the valve and replacing contaminated fluid are effective ways to resolve sticking issues. Additionally, using hydraulic fluid additives can help prevent corrosion and reduce friction.
Erratic Operations
Are you experiencing odd noises and vibrations? These issues can be a sign of air in the hydraulic system or cavitation, caused by rapid changes in pressure that create vapor bubbles.
These bubbles collapse as they move through the system, creating noise and vibrations. To troubleshoot this, we'll bleed air from the system to eliminate pockets that could lead to cavitation. Then, we'll ensure the hydraulic fluid level is adequate, as low levels can exacerbate air ingress.
Pressure Issues
A decrease in system pressure may indicate a faulty pressure valve, leakage, or worn-out components. Pressure-related issues can often be traced back to the pressure relief valve, which is pivotal in regulating system pressures.
If you notice a significant drop in pressure, we can check the relief valve's setting and functionality. We'll adjust it according to the manufacturer’s specifications and replace any worn parts that fail to maintain the desired pressure.
Unexpected Performance Changes
Performance changes, such as sluggish operation or erratic movement, could be signs of clogged filters or overheating components within your hydraulic system!
Over time, contaminants can block filters, restricting fluid flow and causing components to overheat. Routine maintenance, including regular filter cleaning and replacement, is essential for optimal valve performance. If overheating persists, we'll need to inspect your cooling system to ensure it is functioning correctly.
