Industrial oils are used as a lubricant reducing friction and wear of parts and components in various industrial machines. The main functions of this type of oil is anti-corrosion protection, dissipation of heat from friction parts, removal of contaminants and reduction of foaming.

Industrial oils can also be used as the base for hydraulic fluid, as well as grease, that extends durability and service life of industrial equipment.

Despite the fact that practically all industrial oils are thoroughly tested in laboratories before dispatch to the user, the oils will become contaminated during use and operation. Industrial oil, just as with any other oil, can become contaminated by atmospheric oxygen, water and particulate matter. Interaction with aggressive media may accelerate oil oxidation that is accompanied by the accumulation of even more unwanted contaminants in the oil.

Saturation of oil by contaminants degrades the oil’s performance. Due to aging and contamination, industrial oils lose the ability to efficiently dissipate heat and protect equipment from corrosion.

It would seem that the aging process is natural and nothing can be done about it except replacing the used oil with new and disposing of the old oil. A practical operator however, will be concerned by the additional costs of used oil disposal, as well as the frequent cost of oil changes.

Fortunately, aging of oil is not all that critical with the advent of modern additives and oil processing equipment. The aging process therefore, can be significantly slowed and the service life of the lubricating oil can be significantly extended.

It is however, necessary to regularly take oil samples to know and understand the oil’s condition and to detect and identify the contaminants degrading the performance of the oil and to purify the oil in a timely manner.

GlobeCore is one of the leading manufacturers and suppliers of industrial, turbine and dielectric insulating oil purification systems.

The CMM-CM type units and CFU-M filter carts made by GlobeCore are successfully operated in more than 70 countries around the world. They are efficient for the purification and regeneration of industrial oils.

The ability to purify and regenerate industrial oil was made possible by using modern technologies and maximizing and customizing the processing operations for the individual client.

The CMM-CM units are designed for removal for water and solid particles from oil by using a special zeolite sorbent and subsequent reactivation of this sorbent in the system.

The CFU-M filtration carts are designed for removal of solid particles from industrial oil. These units can purify the product in one cycle.

Both types are simple in service and operation and facilitate a significant extention of industrial oil service life cycle.

In any business, be it a toy store or transformer oil sales, there are many fine points to consider. Knowing them will save you time and money. In this article, we will look into the process of supply and receipt of transformer dielectric insulating oil.

Every sale of transformer insulating oil must be accompanied by the correct technical documentation. The information required on the batch can be given in original certificates or in official extracts from the original documents.

Receipt and acceptance occurs before removing the oil for use from the shipping container or tank. Ooil samples must be taken and analyzed for compliance with the product’s claimed and documented performance specifications. Among the parameters that must be varified are:

dielectric strength;
flashpoint;
acidity;
water soluble acid and base content;
particulate matter; and
water.

An analysis of the oil’s oxidation stability and dissipation factor at 90ºС/194ºF should be performed for electric power transformers of 110kV and above. This analysis should also include transformers of especially important facilities regardless of the voltage class or level. If the oxidation stability analysis is to be performed after the oil leaves the shipping container, it is recommended to take samples in the presence of the oil supplier.

For the protection of your company whether buying or selling, and to facilitate arbitration in the matter, should the need arise, one of the samples should be sealed and stored. This will provide all the parties with an used sample of the oil so that the initial oil quality may be detemined even after the oil has been used.

Samples are taken in the following cases:

If supplied in rail road or truck tanks, samples are taken before draining from each tank
If supplied in barrels, the number of samples is determined by the terms of supply, however, there should be at least 1 sample per 10 tons of supplied oil.

If the results of the laboratory analysis are favorable, the transformer oil is taken to the client and pumped into the buyer’s tanks. The oil is then either stored or treated before being used in oil filled equipment like transformers and oil filled switches. Transformer insulating oil is transferred from tanks through hoses using additional special equipment at the storage facility.

If the lab results show that the purity of the oil is not in compliance with the established standard(s), the product must be purified immediately or prior to placement in the oil filled equipment. Failure to do so will most likely result in preamture equipment failure and unscheduled equipment down time.

GlobeCore manufactures and supplies mobile oil treatment units such as the Mobile Oil Station type CMM-M. The GlobeCore CMM-M units are designed for degassing, removal of particulate matter and heating of dielectric insulating oils used in electric power transformers of up to 1150 kV. The CMM-M units can be used to heat oil filled electrical systems with hot oil as well as for vacuum drying and vacuumizing of oil filled equipment.

The following advantages of the GlobeCore CMM-M units should be noted:

Purification of dielectric insulating oil in one cycle;
Significant service life extension of insultaing oil and equipment;
Wide range of equipment options; and
Simple operation and servicing.

The CMM-M units can operate in one of three modes:

filtration;
filtration with heating; and
thermovacuum purification and oil degassing.

Complete purification of I-12 industrial oil

I-12 industrial oil is a general purpose oil with no additives. It is made from sweet crude by selective purification.

This oil is used for lubrication of bushings of straight bar and linking machines, spindles of metal cutters, bearings of low power electric motors, and as an operating liquid in positive displacement of hydraulic drives operated indoors.

Combined purification methods of I-12 industrial oil are based on simultaneous influence of several electrical fields or a field with filtration.

The principle of combining electric field influence and centrifical force is implemented in cyclone separators and centrifuges equipped with a special electrical device.

By design, a triboelectric centrifuge purifier is a multifoil rosette with two chargers that create opposite charges in the industrial oil. The passes through the swirler in a translational-rotational movement. It them passes the oil through a circular ring space. Due to friction with barriers, contaminants become oppositely charged. Centrifugal force moves particles with a positive charge to the outlet wall where they are coagulated with negatively charged particles. The charges are neutralized in the coagulated particles.

Then by the force of gravity and inertia, the particles are deposited in a special settling tank.

Comparing hydrocycling efficiency with that of a similar machine equipped with chargers, the chargers are 40% more efficient on average.

When using centrifuges with electrifying devices, the electric field may be obtained by voltage from an external source or by a triboelectric effect. The triboelectric effect occurs due to rotor friction against special bars. The rotor is made from a special dielectric material. (Plexiglas, PTFE, or some other dielectric material )

It is also possible to combine centrifugal force with a magnetic field. It is done by installing permanent magnets into centrifuge systems to capture ferromagnetic particles. Diamagnetic and paramagnetic contaminants are only influenced by the centrifugal force.

The most widespread of combined industrial oil purification systems are devices combining elecrtric fields and filtration effects. These include magnetic filters, filtering centrifuges and vibration (acoustic) filters.

In centrifuge filtration, the centrifuges operate at relatively low rotation speeds. Contaminants may be removed from the rotor either continuously or occasionally.

A magnetic filter is free from such a disadvange of magnetic purifier as selective removal of only ferromagnetic particles. Such devices, beside permanent magnets, use special filters capturing non-magnetic contaminants. An additional filter element (usually a metal mesh) protects the surfaces of the magnets from tar, sediment and other products of hydrocarbon oxidation.

In vibration filters the oil passes through a vibrating porous membrane. The vibrations prevent sedimentation of contaminants on the surface and reduce hydraulic losses, increasing the filter’s service life.

It should be noted that the combined methods of purifying oil products are not widely used at this time due to the complexity of purifier design.

The principal functions of transformer insulating oils are to serve as a dielectric medium and as a transformer coolant or heat transfer medium. In order to perform these functions, transformer oil must have the necessary qualities at the time of initial impregnation and filling at the factory and later be able to maintain the same quality in normal operation.

High Vacuum Treatment improves insulating fluids that includes transformer oils and silicone fluids. GlobeCore transformer oil purification equipment was developed as a result of 30 years of experience in vacuum treatment of transformer oils.

Benefit

Every company dealing with oil-insulated high voltage equipment (transformers, high-voltage switches, turbines, etc.), shares the problem of having to change and dispose of contaminated oil and fluids. The costs of changing and disposing of insulating oils are frequently very high and need a significant investment in time, labor, and money. At GlobeCore, our equipment offers a practical, proven and economical method to purify oil so that it can be used again and again for your high voltage equipment.

Thermally accelerated Vacuum Dehydration and Degassing of Transformer Oil has gained wide acceptance as one of the most economical methods for the removal of dissolved water and gases.

On-Site Transformer Oil Purification is the most cost effective transformer maintenance service in existence today.

Short Process Description

Hot Filtration Mode

A gear type pump draws in the oil for processing via a valve and a strainer. Processed oil is then pumped through the cartridge filter, the three-way valve and is then discharged to the processed oil vessel via a connecting line.

The above mode is also used for transformer core drying. Transformer oil is circulated through the oil purification equipment. After filtering the oil to remove the particles, the oil is heated up to max. temperature of 800C/1472F. All residual gases are removed and the moisture is evaporated in the vacuum degassing chamber. Residual moisture content can be reduced down to less than 3 parts per million (ppm). Oil purification is a necessary maintenance process for oil-filled transformers and can be employed for removal of moisture from the transformer’s core and solid insulation. Heating of the transformer oil moves the moisture from paper to the oil and allows for its removal from the transformer. The most common mistake made by operators of transformer oil purification equipment is to stop the drying process after reaching oil moisture content of less than 5 ppm. After some time, when normal transformer operation conditions exist, the moisture content of the oil increases. It is essential to dry the transformer oil continuously throughout a long period.

Transformer Evacuation

Another required process is the immediate evacuation of the transformer after pumping the insulating oil out of the transformer tank. The “Vacuum Effect” on the insulation surfaces greatly improves moisture content removal. The process must be repeated several times before the desired effects will be achieved.

Hot Filtration and Thermo-Vacuum Drying

A gear type pump draws the oil in for processing via a strainer and cartridge filter. It then directs the oil to the heat exchanger where the oil is heated by the heat conductor. The oil is then fed to the vacuum drier’s sprayer after being heated to 60C/140F. The Vacuum Pump maintains vacuum in the vacuum chamber. a Vacuum can be regulated by valve(s) and monitored on the vacuum meter. Filtered hot air comes into the chamber and removes gases and vapor from the oil’s surface effectively drying the oil. The air is then discharged into the atmosphere via an oil separator by the vacuum pump. A gear type pump then directs the oil into the processed oil vessel. A programmable thermal regulator switch monitors the plant’s function continuously and maintains the pre-set temperature.
