What Are The Hazards of Oil Contamination To The Hydraulic Station System?

The damage caused by oil contamination to the hydraulic station system is extremely serious, and the forms of the contaminants are also diverse.

Solid particles block the gaps and ports of the hydraulic valve, causing the valve core to become clogged and stuck, which affects the working characteristics and may even lead to major accidents.

2. Contamination and damage of components:

Various contaminants in the oil cause various forms of damage to the components. Solid particles enter the clearance of the moving parts, resulting in surface cutting damage or fatigue wear of the parts. Erosion wear is caused by the impact of solid particles in the high-speed liquid flow on the surface of the components. The moisture in the oil and the oxidation and deterioration products of the oil have corrosive effects on the components. In addition, air in the oil of the system can cause cavitation, which leads to erosion and damage to the surface of the components.

3. Hazards resulting from the mixture of oil and water:

(1) When a certain amount of water is mixed into the gear oil, the oil will become emulsified and cloudy. If the oil itself has poor anti-emulsification ability, after being left still for a period of time, the water and the oil cannot separate, keeping the oil in a white state. This cloudy emulsified liquid enters the hydraulic system, not only causing the hydraulic components to rust, but also reducing their lubrication performance, worsening the damage to the parts and lowering the system efficiency.

(2) When the iron and metal components in the hydraulic station system get rusty, the fallen rust will be present in the hydraulic station system's pipelines and hydraulic components. The rust will flow, spread and diffuse internally, leading to rusting throughout the entire system and causing more rusting and oxidation issues.

(3) The sulfur and chlorine present in water and oil react to form sulfuric acid and hydrochloric acid, which further damages and wears down the components, accelerates the oxidation and deterioration of the oil, and even leads to the formation of a large amount of oil deposits.
