I-20 industrial oil is used for the lubrication of the most common industrial assemblies and components that do not require oils with special anti-oxidation or anti-corrosion properties.
Buying the oil is not the only expense. During operation, the oil’s quality must be monitored and the oil should be purified and regenerated when necessary. The foremost factor in selecting a purification method is the price to quality ratio.
One of the methods of purification that we would like to discuss today are filters and the specifics of their practical use.
Filters have various designs. Selection of a filter configuration depends on operating conditions and the requirements to maintain the oil’s purity. Filters are used practically in all stages of production including the storage and transportation of the oil. Filters are installed in oil storage facilities, oil refineries and in equipment and machinery using oil.
Transportation, storage, and filling of industrial oil I-20 is performed with equal element filters. This type of filter is of simple design and can be operated in a wide range of operating pressures. The main drawback of the equal element filters is the need to disconnect them for filter element cleaning or replacement.
In general, oil filters are cylindrical and vary in design of filter element fixture, the number of filter elements, and presence of safety valves.
The need to change the filter arises when the filter becomes contaminated as indicated by the pressure difference on the filter. This difference is measured by two manometers.
The design of the filter is chosen depending on where the filter will be installed. Oil refineries usually filter industrial oil before shipping the oil to the customer or wholesale distributor.
Filters used in storage parks must have high throughput. Their weight and dimensions do not matter much since the filters are stationary.
Along with fabric filter elements, there are also metal mesh, felt or fiberglass filter elements in the oil industry.
The requirements to filters used for oil in stationary oil storage facilities are similar to those installed in oil refineries.
The main problem with a disposable oil filter is the limited service life. Filter media becomes saturated with contaminants increasing the pressure drop to maximum limits.
Lube oils are filtered mostly through disk filters that can only assure coarse filtration by removing particles larger than 70 microns.
During filtration of thickened oil, the filter’s throughput may be lowered by as much as 30-40% compared to oil without thickeners.
For operation in low temperatures, filters are equipped with jackets with steam or a water inlet for heating.
