Expert opinion about the classes of the hydraulic oil purity

Reliable operation of hydraulic equipment, widely used in various industrial facilities, depends mostly on the quality of the internal cooling and lubrication oil. Such machines operate under heavy loads and sometimes in difficult conditions. Regular maintenance of industrial equipment allows to detect possible malfunction in a timely manner. Presence of solid particles in the oil quickly degrades the oil; among such particles 70-85% are quartz,  10 – 15% aluminum oxide and 5 – 10% iron oxide. Contamination of hydraulic oil disrupts operation of safety and regulation valves.

Complete replacement of oil is not a complete solution, since the system itself is contaminated by metals and sludge. These will contaminate fresh oil filled into the system. The new oil can also be contaminated during incorrect transportation, storage and handling.

The filters built into the hydraulic systems do not ensure the required purification of oil. Oil purity class is not an indication of its compatibility with certain industrial equipment type. Also, it cannot give a precise answer as to the oil’s reliable operation. Equipment loads are a direct influence on the rate of degradation of the oil.

For reliable operation of oil systems and prevention of malfunctions caused by irreversible processes in the oil, it is necessary to use hydraulic oil purification plants.

Selection criteria of such systems are low filtration and regeneration costs, reduction of repair and maintenance costs, high purity of processed oil, removal of sludge and contaminants from oil tanks, mobile or stationary design, compliance with fire and health regulations.

To comply with the above criteria, as well as for minimization of oil purification expenses, GlobeCore developed UVR type units for oil purification and regeneration. These plants are an efficient one-stop substitution for a whole array of filtration and service equipment. One UVR plant on a mobile platform can quickly service several machines. It can easily move around the facility and does not require readjustment for different kinds of oil or equipment.

Availability of oil purification and regeneration plants increases hydraulic system reliability and extends service life, reducing maintenance costs. The complete regeneration and filtration process keeps the oil in specs and reduces the amount of maintenance work and downtime.
