Does the oil contamination in a 500-ton four-column hydraulic machine system have an impact on the equipment?
Does the oil contamination in a 500-ton four-column hydraulic machine system have an impact on the equipment?
Under normal circumstances, the harm of oil contamination to the hydraulic system mainly has the following impacts:
- 1. Contamination wear of components
Various pollutants in the oil cause various forms of wear on the components. Solid particles enter the moving pair gap, causing cutting wear or fatigue wear on the part surface. Solid particles in high-speed liquid flow impact the surface of the component, causing erosion wear. The water in the oil and the products of oil oxidation cause corrosion to the components. In addition, the air in the system oil causes cavitation, leading to surface peeling and destruction.
- 2. Component blockage and jamming failures
Solid particles block the gap and orifice of the hydraulic valve, causing the valve core to block and jam, affecting performance, and even causing serious accidents.
- 3. Accelerate the deterioration of oil performance
The water and air in the oil are the main conditions for oil oxidation with their thermal energy, and the metal particles in the oil play an important catalytic role in oil oxidation. In addition, the water and suspended bubbles in the oil significantly reduce the strength of the oil film between the moving pairs, reducing the lubrication performance.
