• Dielectric oil
• Silicone oil
• Mutual Inductor oil
• Switchgear oil

The Series YH-ZYD-R Double-stage vacuum Transformer Oil Regeneration Equipment can rapidly remove the water content, gaseous matter and impurities found in a wide variety of oils, as well as the poisonous components in the oil fluid such as acetylene, hydrogen, methane, etc. in the insulating oil. This effectively enhances the insulating property of oil and ensures the normal operations of power installation, preventing the occurrences of incidents.

Furthermore, it can also satisfy the on-site installation or troubleshooting and maintenance and implement the vacuum suction for the transformer itself. At the same time, the Transformer Oil Regeneration Equipment is capable of completing the treatment of water and gas removal for the transformer oil, substantially shortening the oil treatment cycle.

It is widely used in a broad range of industries that include power plants, power stations, power companies, metallurgy, petrochemical, machinery, transportation, railways, and more, and is especially suitable for use in large scale voltage transmission and transforming equipment (350 KV – 1000 KV), as well as main national power grid transformers. Additionally, it can shorten the oil treatment cycle for the installation and troubleshooting/maintenance of the transformer.

Fulfilling the work implementation and commissioning specifications (Q/GDW 122-2005) of the national power grid transformers (350 – 1000 KV), oil immersed reactor and mutual inductors, it is also the top-choice equipment for use above the sea level of 500m.

The equipment can effectively remove moisture, gas and impurities from insulating oil, improve the compressive strength and quality of insulating oil, and regenerate deteriorated insulating oil. It can also remove deep oxides, free carbon and other polar substances from oil, and recover dielectric loss, oxidation resistance, acid-base water solubility and other comprehensive indicators of deteriorated insulating oil.

Previous attempts in manufacturing to address these issues saw the adoption of a Regeneration tank with silica gel, designed to absorb the oil acidity impurities and free carbon. However, the results weren’t positive, with more oil wasted during regeneration.

To address these issues, we have now developed the Regeneration filters. The Regeneration filter use resin filter and is based on an ion exchange principle, which absorbs acidic substances or metal ions in fluids, in order to reduce the acidity of fluids or increase the resistivity of oil.

Series resin regeneration filters adopt a large diameter structure and high filling capacity and have a very high contact absorption area and ability. The special high-performance ion exchange resin can purify oil quickly and efficiently. The acid-removing filter element can quickly and effectively reduce the oil acid value.

The acid-reducing capacity reaches 3.7 g molecular acid/liter. It is 5-7 times as powerful as ordinary diatomite and 2.5 times as much as activated alumina.

The oil acid value can reach below 0.1 mg KOH/g.

No metal ions were released in the treatment process, no gelatinous polyphosphate was produced, and no particle leakage pollution occurred.

This equipment is designed with a powerful vacuum system.

Our company adopts rotary vane vacuum pump with a boots pump in the vacuum system (which can provide a higher internal vacuum impact and achieve a better dehydration effect). The vacuum separator adopts short-range distillation film evaporation technology, including short-range distillation technology, which can realize distillation and separation in the vacuum of 0.001 mbar and heating time of less than 1 minute. Therefore, for the substances with high boiling points and thermal sensitivities, it will undoubtedly become the preferred technology for distillation and separation.

Normally, the boiling point of a substance can be reduced by 20 to 50 degrees for reduction of pressure by one order of magnitude. Based on this, the boiling point of the substance at 0.001 mbar should be lower than its normal boiling point of 120 to 300 degrees. At present, short-range distillation technology can be applied to the distillation and separation of substances with a normal boiling point of close to 700 degrees. With the split branch node technology, water can quickly be evaporated in the oil. The design of polarization and the scientific vacuum pressure difference in the vacuum separator are more conducive to the escape of water and gas. With thin film evaporation technology and high vacuum, the system can completely and effectively remove oil, moisture and gas, so as to ensure the rapid separation of moisture content from insulating oil.

The equipment also possesses a precise filtration system.

The primary filter, which adopts a stainless steel mat-shaped net, is made of deep processing, with filtering accuracy of 80μm (optional), a large quantity of pollutants received and a long service life. It’s able to be repeatedly cleaned to reduce the intensity of the cleaning of the filter element.

The secondary filter is made of high-precision stainless steel mat-shaped net imported from Japan, which can be repeatedly cleaned, reducing the time required to unload and clean the secondary filter element and also improving the efficiency of the equipment.

The filtering accuracy is 10μm (optional). Precision filters, made of imported polymer filters from the United States, can effectively intercept impurities of various shapes in the oil. The machine adopts step-by-step encryption, proportionally sharing the impurity removal load of filter elements at all levels, and adopts reasonable fluid design to realize cleanliness and a deep filtration of fine particles in oil. The regenerative filter element adopts a kind of special high-efficiency oil purifier, which can purify and regenerate deteriorated insulating oil, remove acidic polar substances, suspended substances, and precipitated pollutants, as well as removing oil pigments.

For security, the device has multiple security protection systems.

The equipment is equipped with a perfect protection device. Through high temperature protection, over-pressure protection, power cut protection, over-voltage protection, under-voltage protection and phase-out protection of the equipment by various actuators, it can effectively ensure the normal operation of equipment and prevent any accidents from occurring.

The equipment is designed to be operated in a simple and convenient way. When you need to use the regeneration device it’s easily controlled by its control valve, which can be closed when not in use. The regeneration device can be manufactured separately and used in conjunction with the vacuum oil filter. It can also be used as a bypass in oil filter equipment. We have sold this machine for several years, with many customers experiencing high satisfaction with our machines.

Which kind of Turbine Oil Purifier machine will achieve the best results?

The oil used in the adjustment and lubrication system of the steam turbine generator set will mix steam, water or impurities to different degrees throughout the course of its operation. It requires frequent maintenance and treatment. Otherwise, it may accelerate the deterioration of oil quality, cause adjustment and protection system failures, result in bearing bush damage or otherwise influence safe operation of the unit.

In the past, medium and small units generally used a regular pressure oil purifier machine and a centrifugal oil purifier machine to remove impurities and water from the running oil. However, the operation of these two kinds of equipment is complicated and results in a high amount of oil waste. The efficiency of filtering out water and impurities is too low, and the operation requirements of the unit cannot be met.

Before, the oil purification device currently used for 200MW units mainly utilized the principle of settlement and filtration. Its basic structure consists of a sedimentation tank, a filter tank and a storage tank. A multi-layer separation net is arranged in the sedimentation tank. Depending on the gravity difference between the oil and the water, the water in the oil condenses into water droplets as it passes through the separation net, settling in the lower part of the tank before it is discharged from the outside of the tank by an automatic water pump. This oil purifying equipment has a large design capacity and size, and from a practical use perspective, experienced widespread phenomena such as poor water removal efficiency, dirty oil, and easy clogging of purification devices. In addition, there is also an ordinary vacuum type purifying machine, which uses the principle of flushing to remove water and removes impurities with a mesh filter. Such a device is suitable for removing trace water in oil, but for a unit with serious water leakage, and especially emulsified oil, it can’t sustain treatment and isn’t suitable for continuous operation.

The Turbine oil characteristics and problem are as below:

• Water and gas are in two forms in the oil – dissolved water and gas (below the saturation point) are present in most oil systems and oil equipment, and free water and gas (above the saturation point) are present in many oils.
• Due to issues such as system leakage, poor sealing, long-term thermal loads of oil, open storage, and more, moisture and gas in the air settle in the oil, resulting in water and gas in the oil.
• As the system leaks, the dust in the air enters the system and the dust falls off. The oil labors for a long time under high temperature conditions and water. It will inevitably cause some of the oil to crack and create a gelatinous substance.

What damage is caused by water, gas and impurities in the oil?

• Rapidly oxidizes and degrades the oil to form acidic substances and corrode metal contact surfaces
• The precipitation of the additive in the oil fails, the thickness of the lubricating film is reduced, and the mechanical wear is increased
• Lubrication, cooling, and reduced flow properties accelerate metal surface fatigue
• Ice crystals formed at low temperatures block components and reduce system rigidity
• System response is slow and accompanied by irregular motion conduction performance degradation
• Higher oil temperature does not cool
• Oil pump and power equipment are damaged by cavitation

Now, according to turbine oil characteristics, we’ve designed the YH-TY series turbine oil purifier machine to filter out the water, gas, impurities and volatile matters, (methanol, ethanol, acetylene, hydrogen, methane, ammonia) etc. and other dangerous components in the turbine oil. This further raises the quality of the oil, restoring the viscosity, cleanliness and performance of the turbine oil.

Additionally, it effectively ensures the normal operation of the usage of the turbine oil, substantially reduces the occurrence frequency of frictions, elevates the lubricating performance, and minimizes the risk of occurrence of potential incidents. It is most applicable to power generation plants, substations, power stations, oil fields, mines, metallurgical fields, electric power plants, transportation, manufacturing sectors, and other industries that require purification and regeneration of the turbine oil and all kinds of lubricating oils.

YELOCO Series YH-TY Turbine Oil Purifier machine advantages:

1. Strong capabilities in filtering water and demulsification. It easily separates huge volume of water from the oil, and filters out small volumes of water in the oil as well. With the usage of a strengthened hydrophilic and hydrophobic technology (water separation device and filter elements), it comprehensively alters the interactive performances of the two interfaces between oil and water, and accelerates the activity of small little water molecules, combining them together to form a bigger water molecule big enough to be separated from the oil content. This ensures that the cloudy and emulsifying oil becomes transparent and clear.
2. Strong performance in purifying impurities. It uses a filtering material that has a composite microporous structure that is corrosion-proof and heat-resistant. This is a durable and lasting device, with long-lasting usage, and the deeply-layered filtering elements within the large surface area are able to filter out the microscopic impurities from the oil content in deeper layers.
3. It is mainly designed to purify the waste oils that have large water content and are seriously emulsified.
4. The YH-TY series of the turbine oil purifier machine is especially adaptable and suitable for handling turbine oil, hydraulic oil, refrigeration oil and other lubricating oils that require huge amount of water elimination and precise filtering functions.
