The four main points of hydraulic system maintenance
- Oct 18, 2018 -

When hydraulic oil enters the hydraulic system, cleaning is the primary problem. It should prevent dirt and other impurities from entering the hydraulic system. Prevent tiny particles from scratching the valve, jamming the pump, blocking the orifice, resulting in costly repairs. In the following we should pay attention to the following points:


1. Keep the hydraulic oil clean:

Store the oil in a clean location. Care must be taken when changing oil or refueling. Use only a cleaning funnel equipped with a fine mesh to pour oil from the container into the tank.


2. Keep the system clean:

Regular oil and filter changes. Good hydraulic fluids contain a variety of additives that prevent oil from damaging or clogging system parts. However, these additives will lose their effectiveness over time. Therefore, the oil should be replaced periodically to ensure that the additives function. The filter can only absorb a limited amount of dirt particles and other impurities from the oil. Replace the filter at the recommended cycle to keep the system clean.


3. Drain and refuel:

Regular discharge of water and sediment from the tank is important for removing impurities from the oil, but it is also important to periodically vent the entire hydraulic system. This is a reliable method to completely remove system impurities, oxidized hydraulic oil and other harmful substances. The recommended clean hydraulic fluid should be re-added to the system.


4. Cleaning:

If the oil is completely contaminated, especially when the pump is damaged, the oil in the tank must be cleaned. The oil is moved through the oil cleaning device until the oil contamination indicator shows that the oil is in a satisfactory state.
