What Is a Hydraulic Oil Purification System?
A hydraulic oil purification system is a specialized filtration and treatment setup designed to remove impurities from hydraulic fluids. Unlike simple filters, these systems provide multi-stage purification, targeting solid particles, moisture, and dissolved gases. By maintaining optimal oil quality, these systems protect hydraulic pumps, valves, actuators, and pipelines from wear and failure, ultimately reducing downtime and maintenance costs.
Hydraulic oil degradation can lead to:
- Reduced lubrication efficiency
- Increased component wear
- Corrosion in hydraulic circuits
- Unexpected system failure
Purification systems mitigate these risks and help achieve ISO cleanliness standards, which are essential for precision industrial applications.
Oil Purification System Working Principle
After the large particles and impurities removed by the primary filter system, oil will undergo capillary condensation by the demulsifying filter element from demulsifier system, and small droplets turn into large droplets, and then be separated from the oil. Dissolved water is removed by vacuum system through heating constant evaporation and vacuum pump out. After removing water, oil goes through fine filter system to remove mechanical impurities, finally, oil is purified completely.
Hydraulic Oil Filter System Working Process
Lube oil goes through coarse filter system, and sucked into heating system by vacuum negative pressure, oil heated and water separated from of oil in the vacuum degassing tank. The water from oil is discharged by vacuum pump. oil is decolorized and deacidified by molecular sorbent and then recycled by oil regeneration system. also oil can be transported to fine filter system by oil pump and demulsified by demulsifier, oil and water separated, and oil is purified.
