Impurities produced in hydraulic oil filters have serious harm to the system, which may include the following aspects:
1. Damage hydraulic components
Impurities can block or jam small gaps and orifice holes in hydraulic components, resulting in parts that cannot work normally, such as spool blockage, abnormal heating or even damage.
2. Increase wear and tear in hydraulic oil filters
The flow of solid particles into the friction surface with hydraulic oil will accelerate the wear of precision parts such as hydraulic valves, increase internal leakage, and reduce system efficiency.
3. Affect the hydraulic system performance
The impurities destroy the oil film between the moving pairs, increase the leakage amount, reduce the pressure, reduce the responsiveness and rigidity of the system, and are prone to vibration and crawling.
4. Cause oil deterioration
Impurities such as water, air, etc. mixed into the oil will accelerate the oxidation and chemical changes of the oil, resulting in unstable properties of the oil, reducing lubricity, and accelerating corrosion and damage of the components.
5. Gas jam phenomenon
The mixture of air will cause "gas plug", destroy the continuity of liquid flow, so that the valve can not work normally, causing irregular flow and pressure shock.
It is very important to keep the oil clean and prevent oil pollution to prolong the life of the hydraulic system and ensure its stable operation. Regular replacement of hydraulic oil and filter, to avoid high oil temperature, and to ensure that the fuel port and vent clean, can effectively reduce the harm caused by hydraulic oil impurities.
