A ship has hundreds of machinery and systems which helps in its day to day operations.
Lubrication plays a vital role in the smooth running of this machinery by overcoming and reducing heat, neutralizing acid combustion by-products, preventing scuffing, lessening friction and thereby combating wear and tear between two running surfaces.
The main engine lube oil system on ships ensure lubrication of the main bearings through pumping of lube oil by duplex oil filters, to the crossheads, and guides, piston cooling and bottom end bearings through the swivel jointed pipes in the engine casings.

The engine cylinders have their own lube oil system, which lubricates the surfaces between the cylinder wall and the piston rings through a set of concentric nozzles or quills fitted around the cylinder liner.
There are various properties of lubricating oils to be maintained, such as viscosity, volatility, alkalinity, oiliness, detergents.
It is imperative to maintain the lubricating oil’s properties and to ensure it is in good condition.

Therefore, we need a Lube oil purifier on ships for proper purification of lube oil with minimum throughput or batch purification in case of heavy contamination.

Removes impurities and restores / improves the electrical, chemical and physical properties of transformer insulating oils. This oil is an integral part of most large power transformers. It serves two major roles, as a cooling agent and as an electrical insulator between internal components. Contamination of this oil compromises the insulating properties and leads to premature failure of the transformer. This contamination can be in the form of water, dissolved gases, or foreign particles. By processing this oil with a vacuum dehydration unit like the Yuneng Transformer Oil Purifier, this contamination can be removed returning the insulating oil to its original specifications.
The system incorporates high vacuum and mechanical filtration to dehydration, degasification and filter contaminated oil. Engineered with functionality and versatility to meet a wide range of applications with features such as: an inlet pump capable of drawing oil from long distances and low elevations, a unique multi-level vacuum chamber design for rapid degasification, a sophisticated heating control scheme to ensure safe and efficient processing of the contaminated oil, and a variable speed outlet pump to return the processed oil to the transformer being serviced. Control, monitoring, and user interaction are accomplished through an industrial grade touchscreen operator interface. All parameters are easily viewed and adjusted through this interface along with viewing of current and historical data.

Here is we have listed some advantages for transformer oil purifier:
Improved insulation properties of the oil and hence the other media like paper/cellulose insulation
Better the insulation of transformer, longer the life of the transformer and lesser the breakdown of the transformer
Longer the life of the transformer asset, good returns on investment of the asset
Lesser breakdowns and failure of the transformer results in uninterrupted power supply

The YUNENG transformer oil purifier can achieve transformer oil thoroughly dehydrated and remove fine toner. Restore transformer oil to return to raw performance. We have a variety of transformer oil purifiers to choose from, for example, a small online on-Load tap changer (OLTC) transformer oil purifier machine, intelligent transformer oil purifier. Each type of oil purifier has its own features, you can choose from in your own needs.

The increasing rating requirements of modern transformers and electrical apparatus results in greater electrical stress in insulating material and fluids. In order to handle these greater stresses, oils are required to have better dielectric strength, and lower residual water content must be maintained. The timely and proper treatment of these insulating fluids will result in the improvement of the properties of the entire insulating system of power transformers. The principal functions of the insulating fluid are to serve as a dielectric material and an effective coolant. To perform these functions, the insulating fluid must have specific necessary qualities at the time of initial impregnation and filling at the factory which must be maintained at the same quality level in field operation if optimum performance is to be assured.

Almost 75 percent of the transformer failures happen due to contaminated and deteriorated oil. It is important to filter the transformer oil. Regular maintenance is of utmost significance as it is a great financial burden to replace or repair the transformer. Ignoring transformer oil filtration can lead to:
Arcing
Overheating, which reduces electrical efficiency as well as the life of the transformer
Corona Discharges
Decrease in insulating strength of the transformer oil, and more.

The transformer is one of the main assets in the electrical power industry which needs to be maintained for guaranteed uninterrupted power transmission in order to get assured revenue benefits. Transformer oils are important for functional transformers and are the dielectric substance that helps in maintaining their temperature. Transformer oils are vital for the proper running and functioning of the transformers.

About Transformer Oil Filtration:
Transformers require filtered and dried oil. During its usage, the insulating oil absorbs moisture and gets polluted by sopping fibres, dirty particles, aging products, and soot. Even unused oil is not clean enough as it may have absorbed moisture from the air or may have got polluted in the barrel it was stored in. The efficiency of the oil as an insulating material is highly reduced as the moisture level increases. Hence, transformer oil filtration is an important process that eliminates solid particles, dissolved gasses, and dissolved water. The electrical properties of the oil can be enhanced by filtering, dehydration, and degassing. Oil Filtering keeps the transformer in good condition and increases its life.

In use lubricating oil becomes contaminated by unwanted particles in various forms
Carbon deposits,
Oxidation by-products
Metallic particles
Crucial role in “cleaning” the contaminated lubricant and extend its life is the purification through a Lube Oil Purifier.
The efficiency of the Lube Oil Purifier is generally not reflected in the routine lube oil analysis (viscosity, BN, etc.). For instance, the comparison of the analysis results of lube oil samples drawn before and after the Lube Oil Purifier, may reveal no differences. This can lead to the wrong interpretation and conclusion that the Lube Oil Purifier is not working correctly.
Therefore further to routine analysis, one method to demonstrate that the Lube Oil Purifier is cleaning the oil effectively is to measure the number of particles in relation to the particle size.
The Lube Oil Purifier should be in continuous operation as the engine is running in order to ensure removal of contaminants as quickly as possible.
If possible, the Lube Oil Purifier should be in operation also when the engine is shut down to further reduce the level of contaminants. In the latter case, oil temperature for efficiency separation needs to be maintained through heaters. Those installations with their separation plant shut down during engine stop, should consider re-starting the separator prior to engine start-up because contamination (engine leaks, condensation) could have occurred during engine stop.
It is important that the maintenance and operation of the Lube Oil Purifier is done according to the recommendations of the manufacturer.

Paraffin-based – derived from special crudes that contain a substantial amount of n-paraffin. This type of insulating oil is less oxidized than naphtha based.
Naphtha-based – derived from special crudes that contain a low amount of n-paraffin.
During the usage of insulating oil, it may be exposed to materials that can affect its quality. It fails to function due to factors such as excessive-high temperature, oxidation and many more.

Consequently, the oil darkens in colour and the acid in it begins to increase. Oil impurities are one of the major causes of transformers' deterioration.

To avoid transformer failure, your insulating oil should be free from any contamination, dirt and moisture. Thus, a transformer oil filtration process is needed.

In this procedure, insulating oil is tested and treated so that transformers will function efficiently.

Dealing with transformer oil purification
To treat and purify insulating oil, a transformer oil purification process is required. Insulating oil filtration is a process of removing sludge and moisture from the transformer oil.

Rising oil temperature The first step is to raise oil temperature up to 65°C to give latent heat which separates moisture and gases. Heating the oil will make it easier to filter because of the decrease in oil viscosity. Removal of dirt and impurities The second step is to remove sludge and dirt from the insulating oil. There are 2 ways to eliminate dirt in the transformer oil. By filter candles Insulating oil filtration by filter candles can be classified by using a classical edge filter or depth type filter. However, new advancements were made in which transformer oil filtration machines use filter cartridges instead of edge type paper filters. By centrifuging action Another method for separating dirt from oil is through centrifuging. With this process, you can save the recurring cost of changing filters. Dehydration and degasification of insulating oil This is the stage of dehumidification of insulating oil and removal of gasses. This process is completed in the transformer Oil Dehydration Machine.

Gas and steam power plants use lube oil centrifuges to keep the lubricating oil clean and dry. These applications involve hi-efficiency separation of oil and water. They also remove fine sediment from the lube oil.
Condensate leaks from cooling systems contaminate lube oil with water. Sludge particles originating from the combustion process or wear on moving parts contaminate lube oil.
An Alfa Laval lube oil centrifuge removes all solid contaminants & water from the lubricating oil. Purified lube oil is desirable for trouble-free operation of turbines and engines.
These centrifuges are also known as lubricating oil purifier.

The Portable Oil Purifier removes water and dirt from oil. This system is small and portable, has plenty of heat and vacuum to purify small lube, hydraulic and gear oil reservoirs and tanks. The oil purifier excellent for small-batch filtration and purification, such as small tanks, drums and totes.

Portable Oil Purifier models are available for transformer and insulating oil applications, such as small oil-filled transformers, load tap changers, medical devices and electrical equipment that requires clean dry transformer oil.

The necessity for transformer oil dehydration and degassing is known for a long time. Transformer oil is used in power equipment where it provides cooling and insulation protection. Over time aggregated moisture, gasses and solid particles can seriously affect these properties. To remove moisture, gasses, and solid particles transformer oil filtration plant needs to be used.

Transformer (Insulating) Oil act as a medium for insulation in the transformer, circuit breaker, high voltage instruments, etc. Transformer Oil is required to be filtered before use and even filtration is required after periodical time.

Filtration helps in removal of Moisture content, Dissolved Gases, Acidity, Sludge, Corrosion and other unwanted impurities, thus it helps transformer oil to improve its dielectric strength and Moisture content removal in transformer oil.

Transformer oil testing is performed for both new products and for regenerated oil. Water content is a part of the testing is both cases.
Knowing the amount of water in the oil is indicative of its quality, and provides information on the causes of oil and solid insulation dielectric strength deterioration.
The highest allowed concentration of water in transformer oil depends on the type of equipment; on average, no more than 10-20 ppm (grams per ton) is allowed. Detecting such a small amount of water is not simple, and the methods used for the testing must be highly precise and sensitive. Higher concentrations of water may cause transformer failure, so using a transformer oil dehydration machine is a mandatory measure.
Some of the most common methods of measuring the amount of water in the transformer oil are:
filtration;
gas chromatography;
mass spectrometry;
the calcium hydride method;
photoacoustic spectroscopy.

Particulate and water contamination are the leading causes of oil breakdown and hydraulic component failure.

If you’re experiencing any of the following, it’s time to look for a new industrial filtration system:
Replacement of pumps, bearings, proportional valves and servo valves
Increased component wear and corrosion
Loss of productivity from rejected parts, poor cycle times and downtime
High costs for oil disposal and replacement
Leaking seals, sticking valves and blocked ports
Oxidation, additive depletion and varnish buildup
Filter Particulate Contamination to One Micron or Better

Particulate contamination is constantly working its way into your hydraulic system. New machines and even brand-new oil come dirty from the manufacturer. Particulate also accumulates in hydraulic oil from machine wear and dust ingression. Yuneng's hydraulic oil filtration machine can remove particulate to one micron, allowing you to:
Reduce downtime and maintenance costs
Save on fluid disposal and replacement
Improve part quality, machine efficiency, and overall productivity
Achieve any ISO cleanliness goal

Hydraulic oil performs four basic functions. Their primary function is to create force and motion as the flow is converted to pressure near the point of use. Second, by occupying the space between metal surfaces, the fluid forms a seal, which provides a pressure barrier and helps exclude contaminants. A third function – often misunderstood – is the lubrication of metal surfaces. The fourth and final function provided by the hydraulic fluid is the cooling of system components.

If anyone of these functions is impaired, the hydraulic system will not perform as designed. Worse yet, sudden and catastrophic failure is possible. The resulting downtime can easily cost a large manufacturing plant thousands of dollars an hour. Hydraulic-fluid maintenance helps prevent or reduce unplanned downtime. It is accomplished through a continuous program to minimize and remove contaminants.

Yuneng\’s hydraulic oil filtration system adopts a two-stage filtration structure, a large-capacity particulate matter and a multi-stage filtration system to ensure high filtration accuracy.

Present and future transformer ratings require high quality and high purity insulating oils at the point of use.

The increasing voltage and rating of the modern transformer and electrical apparatus results in greater electrical stress in insulating material and fluids. To handle these greater stresses, oils with better dielectric qualities are required. Also, the lower residual water content in insulating fluids and material must be maintained. The proper treatment and upgrading of the insulating fluid will result in the improvement of the properties of the entire insulating media of power transformers. The principal functions of the insulating fluid are to serve as a dielectric material and as an effective coolant. To perform these functions, the insulating fluid must have the necessary qualities at the time of initial impregnation and filling at the factory and later maintain the same quality in the field operation.

Yuneng’s High Vacuum transformer oil purification system upgrades the new or used electrical insulating fluids. These systems and equipment were developed as a result of 50 years of experience in the vacuum treatment of electric insulating fluids.

Our Vacuum oil purifier (also known as Oil Dehydrators, Oil Reclaimers, and Oil Distillation Systems), are made to combine simple operation with high performance, creating more value for your investment.
The main purpose of a Vacuum oil purifier is to remove contamination from refined petroleum oils and other liquid hydrocarbons. These petroleum products are used in many different industrial, marine, and aerospace processes (including hydraulic systems using fluid power, lube oil systems and bearings, and gears and storage facilities, like tank farms).
In petroleum oils like these, you will most often find contaminants like water, gas, lighter hydrocarbons, particulate matter, or even process seal leaks from steam turbine seals or compressor seals.
Contamination may also be introduced into certain systems through contact with the environment, the atmosphere, and the transfer of products from other contaminated sources like tanks, reservoirs, pipelines, and barrels.
Our Vacuum Oil Purifiers and Filtration Systems were developed specifically to solve this wide array of contamination issues seen so frequently within refined hydrocarbon and petroleum products.
The reason Vacuum Oil Purifiers are so effective in removing most forms of contamination is because they use both a vacuum and a specific temperature setting to expel contaminants in the form of a gas, while the desired petroleum product remains as it is in its original liquid form.
A typical vacuum is set at -25\” Hg or higher, with the temperature raised to 150 degrees Fahrenheit. At this setting, most contamination will be evaporated off into the atmosphere and can later be condensed back into a liquid or gas.
