Dear friends, here we AIDA filter introduce a popular type of oil filter to you.
1.Brief introduction
Coalescence Dehydration Oil purifier is a type of oil filter, widely used in the purification of turbine oil and transformer oil, removing water and impurities filtration of oil in hydraulic lubrication system, access hydraulic lubrication systems and improve system cleanliness
2.Technical principles
Different liquids have different surface tension and fluid flow through the holes, the smaller the surface tension, the faster the rate adopted,When a mixture of different liquids into the separator, the first into the coalescence filter, coalescing filter with a multilayer filter media, increasing its aperture layer by layer. Differences due to surface tension, fast-pass oil filter layer, and the water is slow and more; and because the use of hydrophilic coalescing filter material, tiny water droplets is adsorbed on the surface of the filter layer, resulting droplets coalescence. By the kinetic energy of the role of small droplets through the opening race, gradually merged into larger droplets and gravity settlement and oil separation, through the coalescence filter after the oil, the water is still smaller beads in the inertia to move to the separation filter Department. Separated by the special hydrophobic filter material, filter the oil through the separation, the separation of water droplets in the filter is blocked out, while the separation of oil through the filter, and discharged from the exit.
3.Coalescing system
Coalescence system consists of a group composed of coalescing filter, coalescing filter with a unique polarity of the molecular structure of free water and oil in water emulsion through the filter after being together to form larger droplets, and then rely on gravity to sink down to storage tank.
The machine has five filtration systems as follows:
The first stage oil suction filter is located at the oil suction port and the coarse filter protects the oil pump and extends the service life of the main filter.
The second prefilter is located upstream of the coalescer. It can not only prolong the life of the coalescer, but also reduce the content of particles in the filtered liquid.
The third stage coalescer condenses and sinks the water in the oil.
The fourth stage separation filter further blocks the tiny drops of water in the oil, achieving the function of efficient separation.
The filter medium of the fifth-stage fine filter adopts the filter material with high precision and large dirt holding capacity, which can clean the oil safely and efficiently.
4.System features
Combining precise filtration and dewatering two functions into one efficient. It uses advanced the US "coalescing separation" technology for dehydration, which has high efficient dehydration and strong ability. especially is adapted to the large amount of water separation from oil, dehydration ability is far better than the centrifugal method and vacuum method ,you can get rid of all of the oil-water emulsion medium structure ; by filtration, particle filtration system, the cleanliness of the medium can be controlled in a stable state of the system requirements to ensure the cleanliness; the oil does not change the physical and chemical properties, to extend the service life of the oil; energy small, low operating costs; excellent system configuration, continuous strong performance for online operation.
5.Case study
We supply this type oil filter to our Saudi Arabia client in the environmental protection industry; they collect various used oil from different plants, and put into the tanks in their own plant. Once a time, they encounter a user, whose used oil has a content of water as much as 5%. Normally ordinary oil filter cannot fit for this percentage. They asked us whether we have a solution, our engineer studied the sample of the oil carefully, found that there is solid impurities as well as high content water. We propose this coalescence dehydration oil purifier which can remove both the contaminants. Finally they ordered 1 set with flow rate 100 L/min. currently the machine is installed on project site and functioning well. And the processed oil bring great benefits to the our client. As they are satisfied with the product, they ordered 30 pcs of filter cartridge as spare parts last month. They agreed to order more in future.
AIDA filter has focused in filtration products since 1998, with ISO9001 certificate. our factory cover area of 52000 sqm, and have R&D team of 40 staff, with skilled workers which can guarantee quality. Over the past years, we have provided oil filters and filter cartridges to many customers around the world. We welcome you to inquire. I believe we can provide you the most support and have a win-win cooperation.
