Many problems and defects in hydraulic systems have similar symptoms. For example, a sudden or gradual drop in pressure will reduce the speed or power of the cylinder.
Sometimes the hydraulic cylinder may stop under load and not move at all. Often, a decrease in the power of the hydraulic system is accompanied by an increase in the volume of the pump.
In troubleshooting a simple hydraulic system, the main components of this system, including filters, pumps, pressure relief valves, direction control valves or cylinders, may fail or have problems. Therefore, in order to diagnose and find the problem of the hydraulic system, the performance and condition of the mentioned components should be examined. Using the following step-by-step method, you can track the hydraulic system defects and, if necessary, repair the damaged parts or replace.
- Checking the smoothness (filter)
- Checking the pump and pressure breaker
- Check the cylinder
- Checking the starter valve
