Industrial transformer oil filtration machine specifications

An industrial transformer oil filtration machine is designed to purify and improve the quality of transformer oil, used in electrical transformers for insulation and cooling. These machines help in removing contaminants such as water, dirt, sludge, and gases from the oil, ensuring the transformer operates at peak efficiency. Below are typical specifications for such a machine:

 1. Flow Rate:

   - Capacity: The flow rate typically ranges from 500 to 10,000 liters per hour (L/h), depending on the size and design of the filtration unit.

   - Common Flow Rate Options:

     - Small units: 500–2,000 L/h

     - Medium units: 2,000–5,000 L/h

     - Large units: 5,000–10,000 L/h or more.

 2. Filtration Stages:

   - Coarse Filtration: Removes large particles like dirt, dust, and debris using mesh filters.

   - Fine Filtration: Uses finer filters (often micron-level) to capture smaller particles.

   - Vacuum Degassing: Eliminates dissolved gases and moisture in the oil.

   - Dehydration: Often combined with vacuum filtration or using a molecular sieve to remove water.

   - Polishing Filters: Typically used in the final stage to remove fine particles and provide the highest oil quality.

 3. Operating Voltage:

   - Voltage: Usually operates on 380V, 415V, or 440V three-phase power supply, though smaller units may operate on 220V single-phase.

 4. Temperature Range:

   - Operating Temperature: Typically from 40°C to 70°C (104°F to 158°F). Some machines may have heating elements to ensure the oil reaches the optimal temperature for filtration.

 5. Filtration Efficiency:

   - Particle Filtration: Can filter down to 1 micron or smaller.

   - Water Removal: Can remove up to 90% or more of the water content in the oil, depending on the machine.

   - Gas Removal: Effectively removes dissolved gases (like oxygen, nitrogen, hydrogen) using vacuum degassing.

 6. Tank Capacity:

   - Oil Reservoir Capacity: The tank size varies from small (100–200 liters) to large (10,000 liters or more), depending on the unit's design.

 7. Materials:

   - Construction Material: Typically made of stainless steel (SS304 or SS316) for durability and resistance to corrosion.

   - Filter Media: Often includes activated carbon, cellulose, and other synthetic materials designed to capture impurities without contaminating the oil.

 8. Power Consumption:

   - The power consumption can range from 3 to 50 kW, depending on the size and capacity of the machine.

   - Efficiency features like energy-saving motors and automation can help reduce power usage.

 9. Control System:

   - Automation: Equipped with a PLC (Programmable Logic Controller) system to control the filtration process.

   - Indicators and Alarms: Includes oil temperature, filter condition, and pressure sensors, as well as alarms for potential issues like clogged filters or overheating.

   - Touchscreen Interface: For easy monitoring and operation.

 10. Mobility:

   - Some filtration units are designed to be portable, and mounted on wheels or trailers, allowing them to be used in different locations, especially for field service or transformer maintenance.

 11. Additional Features:

   - Degassing System: For vacuum dehydration and degassing, ensure the transformer oil is free from gases and moisture.

   - Oil Sampling Ports: For testing the oil’s quality before and after filtration.

   - Bypass System: Some units include a bypass valve to allow for oil circulation even during the filtration process.

   - Automatic Oil Flow Regulation: To maintain a consistent flow rate and pressure.

 12. Safety Features:

   - Pressure Relief Valve: To prevent damage from excess pressure.

   - Thermal Protection: Automatically shuts down the machine in case of overheating.

   - Emergency Shutdown System: For manual emergency stops.

 13. Maintenance:

   - Filter Replacement Indicators: Alerts when the filters need to be replaced.

   - Easy-to-Access Parts: Designed for simple and efficient maintenance, ensuring minimal downtime.

 14. Dimensions and Weight:

   - The size and weight depend on the flow rate and overall design, but typical units can range from small, compact designs (around 500–1,000 kg) to larger, more industrial models (5,000–10,000 kg).

 15. Optional Add-ons:

   - Oil Regeneration System: Uses chemical additives and a special process to regenerate oil, extending its life.

   - UV Sterilization: Some systems use ultraviolet light to break down organic contaminants in the oil.

The specifications can vary widely depending on the manufacturer and the specific requirements of the transformer oil filtration process.
