foreword

Contamination wear classification of components:

Contaminants in the oil cause various forms of wear on components. Solid particles enter the clearance of the moving pair of the component, causing cutting wear or fatigue wear on the surface of the part. The impact of solid particles in the high-speed liquid flow on the surface of the part causes erosion and wear. The water in the oil and the products of oxidation and deterioration of the oil will corrode the components. In addition, the air in the system fluid causes cavitation, leading to erosion and destruction of component surfaces.

1. Component blockage and clamping failure

Solid particles block the gap and orifice of the hydraulic valve, causing the valve core to block and clamp, affecting the working performance of the valve, and even causing the component to malfunction, resulting in system failure.      

2. Accelerate oil performance degradation

Water, air and heat in oil are necessary conditions for oil oxidation. The metal particles in the oil play an important catalytic role in the oxidation of the oil.

In addition, the water and suspended air bubbles in the oil reduce the strength of the oil film between the moving pairs and reduce the lubricating performance.
