Chapter 6: Transformer Oil Filtering machine use tips

These tips are used for all kinds of vacuum Transformer Oil Purifier machines. As a long-established brand in China, YELOCO, an oil filtration machine company, has had over 20 years of industrial credibility and integrity. The following tips will help you operate the vacuum Oil Purifier machine correctly and increase the life of not only the Transformer but also the oil.

Oil can only be circulated inside the transformer at 1,500 l/per hour. You can open ¾ of the oil outlet valve as well as the machine circulation valve to control oil flow capacity when you are filling oil into the Transformer.
Transfer of oil from one tank to another tank can be done at more than 1,500 L/per hour.
Oil should be circulated through machine filters more than once (twice is preferred) for better cleaning.
Oil should not be heated above 60 degrees Celsius. The maximum suggested temperature is 65 degrees.
If the oil going into the vacuum chamber is too hot, it will boil and overflow. Therefore, YELOCO sets the machine heating temperature to 60 degrees Celsius.
Oil going into the machine should be restricted at the source so that it prevents the machine from over-filling. This would mean that the machine vacuum chamber volume must match machine flow capacity. YELOCO Oil Purifier Machine’s design and make it according to these scientific ratios.
Dirty oil will need to be circulated slower so that the machine can withdraw moisture and prevent machine overflowing.

Chapter 7: How to package the Transformer Oil Filtration?

Why are tin cases used? Well take a look at the following advantages:

Iron box packaging acts as an excellent barrier and provides comprehensive protective properties to the machine. These packaging materials have extremely low (almost zero) permeability to gas, water, and water vapor, good fragrance retention, and are completely opaque and effective. The same properties also avoid the harmful effects of ultraviolet rays from permeating inside the package. Plastics and paper packages do not match these properties for transporting and carrying such huge machines. Therefore, iron box packaging can provide excellent protection for the contents and is conducive to maintaining the quality of the goods for a long time.

Iron box packaging has good mechanical properties and carries high strength. This type of packaging also has good ductility and high strength. They can be processed by stamping, rolling, stretching, welding, etc., and can be made into thin walls. Packaging containers that have high compressive strength and are not easily damaged and can also be combined with other materials to form composite packaging materials with excellent comprehensive performance.

The packaging is convenient and hygienic. Its containers and internal coatings can generally meet the requirements of hygiene and safety and can adapt to different climatic conditions. The waste from this packaging is better treated and can be recycled.

What is difference between hydraulic oil and turbine oil?

June 11, 2019Turbine oil purifier machine Lube oil filter / Hydraulic oil filteroil cleaning oil filtration turbine oil purifier oil purification turbine oil purification oil treatment turbine oil filtration oil purifier turbine oil filtering hydraulic oil purifier hydraulic oil purification hydraulic oil filtering hydraulic oil filtration lubricating oil purification lube oil oil recycling lubricating oil purifier oil regeneration lubricating oil filtration oil filteringvfadmin

I. First of all, let’s talk about the difference between the definition of hydraulic oil and turbine oil.

The definition of hydraulic oil is: hydraulic oil uses the pressure of the liquid to make the hydraulic system as the hydraulic medium, which acts as anti-wear, system lubrication, defensive cooling, rust prevention, etc. for the hydraulic system.

The definition of Turbine oil is: Turbine oil is commonly referred to as turbine oil, including gas turbine oil, steam turbine oil, etc., which are commonly used in the reduction gears, sliding bearings, and hydraulic control systems of the connected units. The main functions of turbine oil are cooling, speed regulation and lubrication.

II. The differences between hydraulic oil and turbine oil performance requirements

Performance requirements for hydraulic oil: Hydraulic oil requires excellent cleanliness. In order to maintain or improve the efficiency of the hydraulic system, extending the life of the hydraulic oil can save some maintenance costs, has a good anti-wear property is the advantage of turbine oil and hydraulic oil.

Performance requirements for turbine oil: Turbine oil must have good rust and corrosion resistance, good anti-foaming and air release, good demulsibility, good stability, and suitable viscosity.

III. The differences between hydraulic oil and turbine oil characteristics

Characteristics of turbine oil: Gas turbine has the characteristics of energy saving and power. During operation, the lubricating oil is subjected to high heat surface, mixed with air (flue gas), pumped and circulated at a considerable rate and used under high pressure. Therefore, gas turbine oil is required to have superior high temperature oxidation stability and wear resistance than steam turbine oil.

Characteristics of hydraulic oil: Hydraulic oil is used as the working medium of the hydraulic system. It mainly transmits hydraulic energy while lubricating the hydraulic components.
Turbine oil generally refers to gas turbine oil and hydraulic turbine oil. Hydraulic oil is used in hydraulic transmission systems. The two environments are different. Turbine oil requires higher rust prevention, anti-foam and anti-emulsification requirements. Hydraulic oil has higher requirements for anti-wear, anti-foam and anti-emulsification

So our company have designed a special series YH-TY Turbine oil purification machine and series YH-TYA Lubricating oil purification machine according to the different characteristics of the oil.

What is the function of YELOCO Hydraulic oil purifier machine/ Lubricating oil purification machine?

May 24, 2019Lube oil filter / Hydraulic oil filterhydraulic oil purifier hydraulic oil filtering lube oil purifier lubricating oil purification lubricating oil filtering lubrication oil purifier oil filtration oil recycling oil purification oil regeneration oil treatment oil purifier hydraulic oil filtervfadmin

What is the function of YELOCO Hydraulic oil purifier machine/ Lubricating oil purification machine?

The series YH-TYA Hydraulic oil purifier machine/ Lubricating oil purification machine is widely applied to power, metallurgic, mine, mechanical, chemical and manufacturing industries for purification of hydraulic oil, freezing machine oil, gear oil, vacuum pump oil, gas engine oil and heat treatment oil.

I. Why these oil need use YELOCO Lubricating Oil Purification machine/ Hydraulic oil filtering machine?

1) Water and gas are in two forms in the oil – dissolved water, gas (below the saturation point) are present in most oil systems and oil equipment, and free water, gas (above the saturation point) is present in many oils.

2) Due to system leakage, poor sealing, long-term thermal load of oil, open storage, etc., moisture and gas in the air settle in the oil, resulting in water and gas in the oil.

3) As the system leaks, the dust in the air enters the system and the dust falls off. The oil works for a long time under high temperature and water. It will inevitably cause some oil to crack and precipitate the gelatinous substance.

What are harms of water, gas and impurities in the lubricating oil?

·Rapidly oxidize and degrade 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.

II. YELOCO Hydraulic oil purification/ Lubricating oil filtering machine function

The Series YH-TYA Hydraulic oil purifier/ Lubricating oil filtering system filters out the water, gas, impurities and volatile matters, (methanol, ethanol, acetylene, hydrogen, methane, ammonia) etc. and other dangerous components in the oil, etc. further raising the quality of the oil fluid, restoring the viscosity, cleanliness and performance of the various oils. Additionally, it effectively ensures the normal operation of the usage of the turbine oil, substantially reduces the occurrence frequency of frictions, elevating the lubricating performance, and avoid the occurrence of any potential incidents.

III. How to treatment these oil?

1) When the Hydraulic oil purification machine/ Lube oil purifier machine is in operation, the oil fluid will first of all flow into the heater under the effect of differences in internal and external pressure of the oil fluid to conduct heat exchange so that the oil fluidity is further enhanced and the water content in the oil fluid is evaporated in the vacuum separator.

2) After the heating process, it will enter into the preliminary purification device to remove the large molecules of impurities.

3) Thereafter, the oil fluid will now enter into the water separator. As the water separator uses an enhanced hydrophilic and hydrophobic technology, it comprehensively alters the interactive performances of the 2 interfaces between oil and water, enabling the microscopic water molecules to accelerate their activities and integrating into a larger water molecule that is big enough to be separated from the oil fluid. The extracted water molecules will settle down on a collection device and be emptied out.

4) The oil fluid will continue to move into a customized and personalized vacuum separator, whereby it capitalizes on the molecular separation principle to execute pressure-changing resolution, vacuum retention, rapid three-dimensional evaporation, and elimination of molecular bonding so that the dissolving water, dissolving gases, and the free gases will quickly break free from the oil molecules and be filtered out. They will first form into the vapor state in the vacuum separator, and then later form into the membrane state so that the contact surface is a few hundred times that of the original in the vacuum, and the water content in the oil will evaporate and be pumped out of the vacuum system under extreme high temperature, highly intensified vacuum, large surface area and high-speed pumping.

5) The dry oil fluid that has been vaporized and eliminated of the water content in the vacuum, will remove the microscopic molecules of impurities in the oil fluid after being pumped into a more precise filtering device through the oil drainage pump, thereby completing the whole process of oil purification.

Why transformer oil filtration machine is required?

Why do you need to purify transformer oil? Rather the first question should be “Why is it important to have purified oil in a transformer?” Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating–reducing the electrical efficiency and lifetime of the transformer. Similarly, water contamination at levels as low as 30 ppm (parts per million) can adversely affect the insulating strength of the oil. With ever-increasing standards for energy efficiency of power distribution transformers, the need to effectively degas will become even more important in the future. Particles contamination also affects the function of insulating oil. So transformer oil filtration machine is required to purify used transformer oil and keep the transformer oil absolutely clean.

It also can shorten the oil treating duration during installation and maintenance of Transformer.
