The lifecycle of hydraulic oil depends on several parameters which can extend or shorten the cycle. Some of these are viscosity, acidity and the amount of additives. Contaminating particles, free water, unfavorable operating conditions (temperature, loads and other conditions) all contribute to aging of oil.
Oxidation is further accelerated at temperatures exceeding 60C or in contact with some other materials. Presence of solid particles, especially larger than 2 micron, promote oxidation.
Contaminants are present in all hydraulic equipment. When the units are operated, friction causes additional solid particles and dust to enter the oil.
Therefore, to maintain high quality of oil and is operational parametes, it is important to protect its chemical composition, avoid overheating and protect the oil from water, minimize the amount of solid particles in the oil.
Oil filtration schedule is important to any industrial business. Filter efficiency depends on pore size. Large solid particles are retained by the filter as the oil passes through it, the smaller ones pass through the filter. Most modern filters successfully remove 1 – 5 micron particles.
Relative amount of solids increases as the size of the particles decreases. This means the oil will still be contaminated after filtration. The amount of contaminating particles will increase during operation and oxidation will be accelerated further.
Using the experience of many companies, it can be inferred that the dominating reason for malfunctions of hydraulic systems is related to contamination of the oil by solid particulate matter. Therefore it is extremely important to remove such contaminants.
As mentioned above, filtration alone is not enough. Microscopic particles pass through fine filters. Besides, water and air need other removal methods.
This is specifically what the UVR systems were designed for. Mobile or stationary design, direct connection to hydraulic systems for oil processing are just some of the features of this regeneration system.
Several filters, special pumps, heating and absorption allow removal of the smallest particles, as well as water and air from hydraulic oil. The sorbent media is can be reactivated shortly after running purification cycle is complete.
Oil purity regulations, savings on new resources and storage, unification of purification and filtration equipment are just some of the benefits of using the UVR type hydraulic oil purification system.
