The main factor in determining the length of time to complete the purification process, is the degree or level of oil contamination. The higher the “Acid Number” of the oil. the longer the process will take to complete. In any case, the process should be controlled by special instruments.
Any new components installed into a hydraulic system must be just as clean or more clean as the ones already installed. Component manufacturers are obligated to provide information on the purity of each component. In case of hydraulic tank contamination, it must be cleaned during oil processing. At the end of the process, the purity of oil will only be as clean as the cleanliness of the tank’s internal surfaces. If hydraulic liquid is replaced by another, insoluble and not mixed with the original liquid, the time of purification increases drastically.
The Purification Process requires checking all filters and possibly replacing them as required. The common misconception is that filters are a universal solution to maintain the cleanliness of oils and fluids. Filters are not intended for the purification of heavily contaminated oil or fluids that may contain particles of metal, sand, small stones and other foreign objects. Oil, water or air contaminated with such particles will remain contaminated after passing through the filters. To ensure full system purification, it must be completely rinsed. Oil and other fluids must be filtered thoroughly through an external filter. This method however, has certain drawbacks, of which the most important one is the significant time required for external purification. A good example of a long purification process is a large lifting machine which may take up to 15 hours to complete.
The only way to ensure the reliability and durability of hydraulic motors, pumps and other hydraulic components is efficient filtration (removal ) of solid particles and moisture from hydraulic fluid. The existing national and international standards define the norms which the fluid must comply with. (16/14 class, ISO 4406) Absolute filtration fineness is set at 3 microns.
Depending on the specific type of equipment, the purity requirements of the fluid may vary. The versatility of purification and filtration systems therefore, becomes very important. Versatile systems allow for operation with different types of fluids and ensure the required purity class regardless of original contamination.
This is just what GlobeCore offers. The GlobeCore UVR vacuum purification plants lighten and purify fluids, remove aromatics from turbine oil, industrial oil, and transformer oil as well as other petrochemical products, e.g. dark diesel fuel, HFO, gas condensate etc.
