ZJB Single-Stage Vacuum transformer oil refinery machine is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. From the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which have insulation system.
Edges:
◆ Compare with Double-Stage Transformer Oil Purifier, ZJB haven't Roots pump
◆ Eliminates water, gas and impurities effectively by utilizing the unique technology of 3D Stereo-Evaporation, hence improve the voltage withstand strength and the quality of oil, which ensures a safe operation of power generation equipment.
◆ It can inject the insulation oil into the transformer devices, and has the function of electrification online operation.
◆ Enhance the value of breakdown voltage greatly..
◆ Easy handling and maintenance.
◆ Adopts double infrared liquid control automatically system to control inlet and outlet the oil smoothly.
◆ Lower maintenance and replacement expenses.
◆ ZJB-T series equipment can be used for testing insulator withstand voltage and print the result automatically.
◆ Low maintenance and replacement expresses.
◆ Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters.
◆ High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.
◆ Utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.
◆ This machine can work independently, also it can work with the oil regeneration system that can eliminate the acid, the color and reduce the PH value effectively, then further enhance the insulation value of oil.
Structure
◆Dehydration (Degas) System
1, The vacuum vessel can evaporation area efficiently. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the evaporation area of vacuum vessel is three times more than that of the general vacuum vessel. This innovation can dehydrate and degas effectively and efficiently.
2, The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.
◆Filtering System (particulate matter removal)
1, The filtering materials with variable apertures are made of specialized glass fiber. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method.
2, The filtering system has stable and prefect filtering fineness. The filtering fineness has several grades, including 0. 5, 1, 2, 3, 5, 6, 10 Micron etc. Oil β> =1000 after filter.
3, The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully.

1) Working principle
When the oil purification starts, firstly contaminated oil enter into heater, secondly flowed into pre-filter under the difference pressure, in which the large impurities are removed. Thirdly oil goes into intermediate filter. Fourthly oil flow into water separator, the water separator adopts a special skill which changes the change the impaction of oil and water to speed up trace water and coagulate big water which is separated from oil and stored in water content. After that, oil passes through the fine filter and fine particles of matters is removed during the process. Finally oil flows into vacuum pump which use stereo-evaporation removing residual trace of water and steam is condensed in the condenser or expelled out by the vacuum system. the oil was transported out by oil pump. The purification process has finished.
