3. Hydraulic Valve Problems
Hydraulic valves control the flow and direction of the fluid in the system. If the valve gets stuck, clogged, or the solenoid valve stops working, it can mess up the fluid flow, causing delays in how the parts move. Wear, rust, or dirty oil inside the valve can make it respond slowly, which means the hydraulic cylinder or motor won't work on time. Also, if the electronic parts of proportional or solenoid valves fail, it can mess with how the valve adjusts.
4. Air in the System
Air can sometimes get into the hydraulic system if the seals aren't tight or if the maintenance is done wrong. Air can compress, which lowers the system's efficiency and causes cavitation. Cavitation can slow things down and even damage key parts like the pump and valves.
5. Internal leakage of hydraulic cylinder
Hydraulic cylinder is the executing component of hydraulic system, and the wear or leakage of its internal seals can affect the ability of oil to push the piston. If the seal is aged or damaged, the oil may leak inside the cylinder block, causing the piston to move slowly. Internal leakage of hydraulic cylinders may also cause an increase in system oil temperature, exacerbating wear and aging of other components.
6. Load exceeds the carrying capacity
The design of hydraulic systems needs to match the actual load. If the actual load exceeds the designed carrying capacity of the system, the response speed of the system will be greatly reduced, and even there may be situations where work tasks cannot be completed. Long term operation under overload conditions can also exacerbate the wear of hydraulic system components, leading to a decrease in overall system performance.
