What is the High Vacuum Transformer Oil Purifier Working Principle？
- The 6000LPH high vacuum transformer oil purifier works by passing oil through the machine to remove impurities.
- The machine uses a special vacuum separator that uses the principle of cavitation.
- Cavitation expands the contact area of the oil in the vacuum separator hundreds of times.
- The cavitation system continuously increases the surface area of oil evaporation and constantly updates the evaporation interface.
- This maximizes the oil travel in the vacuum system and the static water volatilization area.
- As a result, the water in the oil can be quickly evaporated under conditions of low heat, high vacuum, large surface, and high pumping speed.
- The evaporated water is then discharged from the vacuum system.
What are the Advantages of the High Vacuum Transformer Oil Purifier?
The advantages of vacuum transformer oil purifiers produced by YUNENG are as follows:
- The transformer oil purification system is a purification technology that integrates low-temperature physical adsorption (removal of dielectric loss, decolorization, and deodorization) and online regeneration of adsorption filters. It has functions such as high-speed purification and oil quality protection. hydrocarbons.
- The oil purifier is specially designed for the purification of electrical insulating oil in oil-filled electrical equipment, especially for the purification of UHV, EHV transformer oil, or other insulating oils.
- This oil purifier can be used to degas, dehydrate, filter, and restore the dielectric strength of insulating oils. Through dehydration, degassing, filtration, and other processes, dissolved gas, moisture, solid particles, and pollutants can be completely removed.
- The oil purifier is a very efficient, durable, and user-friendly high vacuum oil purification device on the market today. Purpose-designed design features maximize the pumping rate of our systems, and state-of-the-art components and workmanship ensure years of maintenance-free operation and performance.

How is the High Vacuum Transformer Oil Purifier Operating?
The following describes the operation of transformer oil purification plants:
1. Initial Setup and Pre-Start Checks
- Vacuum Level: Set the desired vacuum level on the electric contact vacuum gauge within the range of -0.07 MPa to -0.09 MPa. This range may vary slightly depending on the specific purifier model and altitude.
- Temperature Control: Set the temperature controller to a suitable temperature range based on the oil type and altitude. Generally, a temperature range of 45°C to 65°C is recommended.
- Valve and Equipment Checks: Ensure all valves are closed and the vacuum pump is primed and ready for operation. Verify the proper functioning of the oil level gauge, solenoid valves, and other control systems.
2. Vacuum Pump Activation and Monitoring
- Open the intake valve on the vacuum pump and start the pump.
- Closely monitor the vacuum gauge to ensure the vacuum level steadily increases and reaches the pre-set value within the specified timeframe.
3. Electrical Activation and Oil Processing Initiation
Once the desired vacuum level is achieved, activate the electrical contacts. This will automatically trigger the following actions:
- Oil Inlet Solenoid Valve: Opens, allowing oil to flow into the vacuum tank.
- Heater: Activates when the temperature controller reaches the setpoint and the oil inlet solenoid valve is open, ensuring proper oil heating during processing.
4. Automatic Oil Level Control and Circulation
As oil enters the vacuum tank, the infrared oil level controller monitors the level.
- Lower Limit: When the oil level reaches the lower limit, the controller automatically opens the oil outlet solenoid valve and starts the oil pump. This initiates oil circulation through the purification process.
- Upper Limit: If the oil level exceeds the upper limit, the controller automatically closes the oil inlet solenoid valve, stopping oil inflow and preventing overflow.
- Low Level Protection: If the oil level falls below the lower limit, the controller automatically stops the oil pump, protecting the purifier from dry pump operation.
5. Oil Sampling and Analysis
- After the purifier operates stably for a sufficient period and the oil has been circulated through the system several times, representative oil samples can be collected from the designated sampling port.
- These samples should be analyzed for relevant parameters like dielectric strength, moisture content, and particulate contamination to assess the oil’s condition and purification effectiveness.

What is the Difference Between Single-stage Transformer Oil Purifier and Double Stage Transformer Oil Purifier?
The single-stage transformer oil purification plant is applicable to the treatment of insulating oil of small transformers and the purification of transformer oil, transformer insulating oil, circuit breaker oil, etc. It is applicable to transformers below 110KV. The equipment is simple to operate and can quickly and efficiently filter water, gas, impurities, etc. in oil products. It is mainly used in power plants, substations, power industry, etc.
The double-stage transformer oil purification system is applicable to the oil purification treatment and vacuum hot oil circulation drying during the installation and maintenance of various large transformer equipment. Especially suitable for transformers above 110K. The function of the two-stage transformer oil purifier is more perfect than that of the single-stage vacuum oil filter. The effect of removing mechanical impurities, gases, moisture, water-soluble acids, and alkalis is faster and more thorough, and the ultimate insulation strength and flash point of oil products are improved more.
What is the Difference Between a Vacuum Oil Purifier and a Centrifugal Oil Purifier?
The dehydration speed of a centrifugal oil purifier is very fast, but the filtering accuracy is not as high as that of a vacuum oil purifier. The micro water cannot be filtered, the emulsification cannot be broken, the gas cannot be removed, and the acid value cannot be reduced. It is not suitable for industrial oils with high requirements on cleanliness, water content, and gas content.
The centrifugal oil purifier needs to clean the system frequently. The system installation workload is large, the installation requirements are high, and the equipment cost is high. Therefore, many power plants and steel plants have stopped using centrifugal oil purifiers.
The vacuum oil purifier is very suitable for filtering various industrial oils with high water content requirements. Suitable for precision filtration, at a moderate price. Both new oil and oil deteriorated after use is suitable for vacuum oil filters.
