Double-axle trailer-mounted oil purification combines stable mobility with efficient vacuum dehydration, degassing, and precision filtration for reliable on-site oil treatment.
This Transformer Oil Filtration Machine is a mobile oil purification system designed for on-site transformer oil treatment. The equipment is mounted on a double axle trailer, providing higher load capacity, improved stability, and safer transportation compared with single-axle designs.
This structure distributes the equipment weight more evenly, reducing the risk of instability or tipping when traveling on uneven roads, and ensures safer operation during field transportation an4d positioning.
Double-Axle Mobile Design:
The heavy-duty double-axle trailer provides improved load distribution, transportation stability, and mobility. The system can be moved between substations, power plants, transformer maintenance sites, and other field locations.
Fully Enclosed Protective Cabinet:
The oil purification components are installed inside a durable enclosed cabinet, helping protect pumps, filters, electrical parts, and pipelines from dust, rain, sunlight, and accidental impact during transportation or outdoor operation.
High-Efficiency Vacuum Purification:
The system combines vacuum dehydration, degassing, controlled heating, and precision filtration to remove moisture, dissolved gases, and suspended particles from transformer insulating oil.
Advanced Oil Dispersion System:
An atomization and three-dimensional vacuum separation structure increases the oil’s exposure area, allowing water vapor and dissolved gases to separate more efficiently under vacuum conditions.
Multi-Stage Precision Filtration:
Progressively rated filter elements remove contaminants of different sizes while protecting the fine filtration stage. The primary filter can be cleaned and reused, helping reduce maintenance costs and secondary contamination.
Uniform and Controlled Heating:
The heating system raises the oil temperature evenly to improve dehydration and degassing efficiency. Automatic temperature control and overheating protection help prevent thermal damage to the insulating oil.
Reliable Control and Safety Protection:
The system can include phase-sequence protection, overload protection, overpressure alarms, automatic temperature control, liquid-level monitoring, and electrical interlocks for stable and safe operation.
Oil-Type-Matched Transfer Pumps:
Oil pumps are selected according to the oil type, viscosity, and required flow rate, helping maintain smooth oil transfer and consistent treatment performance.
Flexible Optional Configurations:
Available options include PLC control, touchscreen operation, online moisture monitoring, a BDV oil tester, trailer lighting, brakes, hose storage, toolboxes, custom electrical systems, and customized cabinet or frame designs.
