What Is a Transformer Oil Filtration Machine with Double Axle Trailer?

A Transformer Oil Filtration Machine with Double Axle Trailer 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.

FAQ

Transformer oil is cleaned using a transformer oil filtration machine that removes moisture, gases, and solid contaminants from the oil. The process typically involves heating the oil, vacuum dehydration, degassing, and multi-stage filtration. Heating reduces oil viscosity, allowing water and gases to separate more easily. The oil then passes through a vacuum chamber where dissolved moisture and gases are extracted. Finally, precision filters remove fine particles and sludge.

This process restores the oil’s dielectric strength, insulation performance, and cooling capability, helping extend transformer service life and improve electrical reliability. Regular transformer oil purification is widely used in power plants, substations, and industrial electrical systems.

A transformer oil filtration machine works by heating the oil and using vacuum separation and filtration to remove moisture, gases, and solid impurities. The system first pumps contaminated transformer oil into a heating unit to lower viscosity and improve separation efficiency. The heated oil then enters a vacuum chamber where water and dissolved gases evaporate under reduced pressure.

After dehydration and degassing, the oil flows through multi-stage precision filters that capture suspended particles and sludge. This combination of vacuum dehydration, degassing, and fine filtration restores the oil’s insulation properties and dielectric strength, ensuring safe operation of high-voltage transformers.

The price of a transformer oil filtration machine depends on several key factors. Capacity is a primary consideration, as higher processing rates require larger pumps, heaters, and vacuum systems. The design and performance of the vacuum system, filtration precision, and number of filtration stages also affect cost, with multi-stage high-precision systems being more expensive.

Additional factors include the heating system power, level of automation (PLC control, safety features, touch-screen interfaces), and mobility or structural design, such as trailer-mounted units for field operations. Customization options, special voltage requirements, and certifications like CE, ISO, or SGS can further influence the final price.
