Harm of oil pollution to the system

1) Contamination and wear of components

Various pollutants in the oil cause various forms of wear of components, and solid particles enter the clearance of the moving pair, causing cutting wear or fatigue wear on the surface of parts. The impact of solid particles in high-speed liquid flow on the surface of components causes erosion wear. The water in the oil and the products of oil oxidation deterioration will corrode the components. In addition, the air in the oil of the system causes cavitation, which leads to denudation and damage of the component surface.

2) Blocking and clamping failure of elements

Solid particles block the clearance and orifice of the hydraulic valve, causing the valve core to be blocked and clamped, affecting the working performance, and even causing serious accidents.

3) Accelerate deterioration of oil performance

The water and air in the oil are the main conditions for oil oxidation with their heat energy, and the metal particles in the oil play an important catalytic role in the oil oxidation. In addition, the water and suspended bubbles in the oil significantly reduce the strength of the oil film between the motion pairs, reducing the lubrication performance.
