Applications of Transformer Oil Filtration Machine

ZJA Series high vacuum transformer oil filter machine is mainly used in the power industry, power stations, power companies, metallurgy, chemical machinery, transportation, railways, and other industries. It is used to filter the oils such as transformer oil, and imported oil.

• Oil filtration can be performed on-site.
• Vacuum dry damp electrical equipment.
• Vacuum the newly installed or overhauled transformer, and carry out vacuum oil injection at the same time.

How Does ZJA Double Stage Transformer Oil Filtration Machine Work?

1. The process begins with the oil passing through a pre-filter and entering a heating unit.
2. Inside the vacuum separator, the heated oil undergoes separation, with a vacuum pump and roots pump at work.
3. Subsequently, the root pump directs the oil to the condenser, while water vapor molecules are drawn into a water receiver.
4. Through a secondary filter and fine filter, the oil is processed as it exits the oil pump.
5. The steps in the operation include:
   • Creating a vacuum by expelling air from the vacuum tank with the vacuum pump.
   • External oil enters the primary filter via the oil inlet pipe, where larger particles are removed.
   • Heating the oil to 45~65℃ in the heating tank before automatic oil float valve regulation.
   • The rapid rotation of the jet wing separates the heated oil into a semi-mist, causing water in the oil to evaporate into vapor, which is then drawn into the condenser by the vacuum pump.
   • Cooling the water vapor in the condenser, results in its conversion back to water and release.
   • Discharging the oil in the vacuum degassing and dehydration chamber through the oil discharge pump, with fine particulate impurities being filtered out by a fine filter.

Why We Need Transformer Oil Filtration Machine?

• The transformer oil will be aged or polluted after running for a period of time, and mechanical impurities, moisture, gas, etc. will enter the transformer oil.
• Both new oil and transformer oil after a period of use need to be filtered. At this time, the role of the transformer oil filtration machine is reflected. The equipment can effectively remove water, gas, suspended impurities, precipitated impurities, etc. from inferior transformer oil.
• It can filter and purify the inferior transformer oil and switch oil, improve the oil quality, and restore the viscosity, flash point, and service performance of the lubricating oil, so as to ensure the normal operation of the transformer system.

What are the Advantages of the Transformer Oil Filtration Machine?

This high vacuum transformer oil filter machine offers several advantages when it comes to filtering waste oil.

1. It utilizes vacuum separation technology, enabling a vacuum degassing separation process. This technology effectively doubles the evaporation area and extends the oil’s residence time in the vacuum chamber. As a result, it enhances the quality and reliability of the filtered oil.
2. Enhances the interaction between water and gas molecules, achieving multiple vacuum cycles.
3. Equipped with a vacuum pump precooler, which reduces water intake into the vacuum pump.
4. Decrease the frequency of vacuum pump oil replacement and prolong the vacuum pump’s lifespan.
5. Heating and high vacuum quickly remove water from oil due to the lowered boiling point of water in oil under high vacuum conditions.
6. Remove impurities from the oil, and achieve the goal of oil purification.
