Low temperature vacuum distillation system
There are two forms of varnish in lubricating oil: insoluble and soluble. WVD varnish removal oil purifier provides insoluble varnish removal system (electrostatic purification) and soluble varnish removal system (resin adsorption).
Lubricating oil varnish is a kind of high molecular hydrocarbon polymer, which is the product of oil oxidation. Its color ranges from light brown, brown to tan, which is named for its appearance similar to the film of anticorrosive paint. It is common in the mechanical lubrication and hydraulic system with high temperature, high pressure and high speed rotation. The varnish has polarity and is easy to adhered to the metal surface.
1. Reduce the clearance between the bearing bush, increase the friction between the surface of the bearing bush and the shaft, and increase the temperature of the bearing bush.
2. For some turbine control oil systems, when the varnish is serious, it can cause the filter screen of the electro-hydraulic converter in the control oil circuit and valves blocked.
3. Clogging filter results in poor lubrication of the equipment.
4. The varnish deposited on the cooler causes poor heat dissipation, oil temperature rise and oil oxidation acceleration.
5. The varnish will adhere to solid particles, which will cause abrasion of equipment.

WJDTM technology is able to remove insoluble contaminations during degradation processes as soon as possible. Experimental results show that Electrostatic Absorption technology absorbs hard and soft pollutants through the flow of particles with charge during oil circulation, preventing your system away from the pollution of varnish and sludge. Compared to several of the competing technologies, WSD WJDTM technology can at least increase the rate of removing the sludge/varnish by 200%.
The degradation products that form the varnish will exist in the oil in the suspended or dissolved state. The electrostatic adsorption technology mainly aims at the degradation products in the suspended state, but the degradation products in the dissolved state should not be removed by the electrostatic adsorption equipment. WSD can continuously and selectively remove the degradation products in the dissolving state by using special ion exchange resin. The resin contains billions of polar sites, which can adsorb the degradation products in the dissolving state. This adsorption depends on the interaction between the polar varnish molecules and the priority molecules existing in the resin, just like the polar varnish prefers to be on the polar metal surface as coating, it also prefers to be adsorbed on the polar part of the resin.
