Seventy percent of hydraulic and lubricating component failures occur as a direct result of surface degradation due to corrosion and mechanical wear. Oil that has water (moisture) content will significantly reduce the lubricating properties of the oil contributing to increased mechanical wear.

 

So, prevent it with ASSEN Oil Purifier Systems.

We have standard and custom-designed equipment for hydraulic press operations, ASSEN TYA Hydraulic Oil Filtration system circulates oil at a very low velocity, removing submicron particles and large contaminants from hydraulic fluids and lubricating oils. The special design and mature technology can promise its after-treatment oil index:

How does oil filtration machine work? http://www.assenpe.com/2017/08/22/how-does-oil-filtration-machine-work/ Tue, 22 Aug 2017 06:56:08 +0000 http://www.assenpe.com/?p=1019 ASSEN is professional manufacturer of High vacuum Transformer Oil Filtration System Plant

  • Advanced dehydrating and degassing system that uses large area three-dimensional flash distillation technique to remove moisture, gas from the transformer oil and paper insulation
  • Mesh filters capture particles in the transformer oil
  • Liquid level detectors and controls ensure internal components are not exposed

 

ASSEN Company offers a high degree of dehydration and degasification leaving your transformer oil dry and free of unwanted oxygen and combustible gases.

Dehydration
Moisture within a transformer can lead to premature aging, can increase the rate paper decay and lead to the dielectric failure in extreme cases.  Assen Transformer Oil Dehydration Treatment will reduce the moisture content of transformer oil and windings.   A dehydration treatment can be conducted via a hot oil dry-out or a high vacuum dry-out.

Degasification
ASSEN Transformer Oil Degasification Treatment is often conducted on a unit that has had oil removed or added during the course of installation, maintenance or repairs.  In addition, a Degasification Treatment is used to reduce dissolved combustible gases caused by internal electrical faults and overheating.  The ASSEN degasifier is specially designed for processing transformer oils and in preserving the integrity of transformer insulation system.

Vacuum filling
The fundamental function of this treatment is to replace the existing transformer oil of low quality, with new or reclaimed oil of acceptable quality. The current oil is drained from the transformer into a storage tank.  The transformer is, then, filled with new oil using a vacuum-filling technique. vacuum filling a transformer is an efficient method of removing contaminated oil and is ideal when little down-time can be afforded.

Oil Purification Process http://www.assenpe.com/2017/06/22/oil-purification-process/ Thu, 22 Jun 2017 02:32:05 +0000 http://www.assenpe.com/?p=1005 Transformer Oil Purification is a process of purifying the transformer oil by eliminating or reducing physical contaminations, such as particles, water content, gas content, and others. Referring to this three contaminants, the transformer oil purification generally goes through the stages

Filtration (oil filtration)

De-humidification (removal of moisture), and

De-gasification (dissolved gas dissolution)

 

In another word, Transformer Oil Purification process is also named one combination of two treatment procedures. The filtration process and the vacuum process; filtration process can filter particles > 0.1 microns, while the vacuum process remove most of the dissolved water and eliminate the gas content in the transformer oil. This simple operation usually enough to correct the low voltage of electricity(caused by the combination of particles and high water content)

 

At last, transformer oil purification has the functions of on line work, vacuum drying and vacuum oiling.

High Performance On-line Reconditioning of Transformer Oil http://www.assenpe.com/2017/06/08/high-performance-on-line-reconditioning-of-transformer-oil/ Thu, 08 Jun 2017 01:47:28 +0000 http://www.assenpe.com/?p=992 on-line transformer oil reconditioning machine

 

Electrical Transformer Equipments continually face the need to reduce the level of contaminants in transformer oil in order to maintain performance, prevent failure, and extend service life. Maintenance personnel often monitor the accumulation of contaminants in the oil, such as acids, alcohols, corrosive sulfur and moisture. The solution is on-site hot oil reclamation and filtration. ASSEN® uses highly effective method to treat oil into like new conditions conforming to the IEC 60422 standard without a requirement for oil change.  Treatment of oil is carried on site where adsorption agents absorb all the degradation products from degraded transformer oil without interrupting the transformer operation.

After restoring oil properties to the level of new oil, the unit will keep the oil clean and dry at all times preventing the accumulation of other oil and paper degradation products from reaching harmful levels in the paper insulation, which will extend the life of the paper insulation and consequently the life of a transformer.

 

Key Features:
1.A capability of reducing moisture content from 50ppm to 3ppm moisture and 12% gas content to less than 0.1% by volume. 98% of particulate matter will also be removed.
2. Removal process is working on-line with in-service transformers and avoiding system shut-down.
3. Double-Stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value no more than 5Pa
4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas, from oil.
5. It is humanization design with low noise,deep purification and long time free maintenance to save cost from the running process

How to improve the working efficiency of vacuum oil purification? http://www.assenpe.com/2017/05/29/how-to-improve-the-working-efficiency-of-vacuum-oil-purification/ Mon, 29 May 2017 07:43:02 +0000 http://www.assenpe.com/?p=989 Best daily preparations, no chaotic situation, It is able to effectively improve the efficiency of vacuum oil purification. But if you want more better performance, you should check the vacuum pump if is fit for your model, we must choose the equipment applicable to the model, specially in technology, performance, material have the advantage. So as to easy to improve its efficiency.

Before we start the machine, we should check whether the connection of the inlet hose and outlet’s in place, and ensure inside way is no block. We need to pay attention to the oil pump that can’t be reversed when it started, so as not to damage the seal of the pump shaft to cause inhalation of air.

When your oil purification machine running some times, it come with insufficient oil inlet, abnormal noise, which situations mean the filter is full with contaminants. It’s time for cleaning the filter or replace it.

The specifications of the cylinders used in oil purification are different, Although the models are different but the role they play is exactly the same, they are an indispensable part.

How to solve the leak point on oil purifier plant? http://www.assenpe.com/2017/05/13/how-to-solve-the-leak-point-on-oil-purifier-plant/ Sat, 13 May 2017 02:58:05 +0000 http://www.assenpe.com/?p=929 Leakage phenomenon come out in normal vacuum oil purifier’s operation was a very common thing, how could we to solve it? And how to determine when the machine is running the water vapor generated by the vacuum or decreased due to the machine itself sealing problems, with leak it?

For the above questions, here we can do
1.we can only start the vacuum pump, if the vacuum degree of machine at this time is not high, it probably the purifier’s leakage problem.
2.we can check the vacuum pump’s running, to see if low speed? And check the vacuum oil if is deterioration. Replaced the new vacuum oil, if the vacuum pump is still low speed, there may be the problem on vacuum pump’s. then we should replace the whole pump.
3.If there are leaks in other parts of the machine, how could we to find them?
a. Closed all the external valve and injecting pressure in it, using detergent water to brush all sealing parts or welding paces, a careful look where there is bubbling, and if so, then this place is a leak. If the flange is leaking, we can tighten the screws, or replace the pads. If the O-ring’s connection wire teeth is broken, we can unload it, re-painted sealant, and install a new O-ring. If there is leakage point of the weld, if small, we can use high-performance industrial adhesive, or with a nail beating around the patch, if you really leak a lot of places, you need to welding again.
