Several major uses of oil filter equipment

There are many types of oil filters on the market. For many users who don't know much about the functions, scope of use and purpose of such equipment, it's a bit confusing. As an oil filter manufacturer, I will popularize some knowledge about the uses of oil filters to help users make some references when choosing oil filter purification equipment. At present, the types of oil that can be processed by oil filters are mainly lubricating hydraulic oils, insulating oils, and light fuel oils. According to different functions, they are mainly divided to achieve the following purposes.

Preventive purification

Such as the factory filter of the finished oil depot, the oil filter of each oil-using unit, and the online oil filter of various machines and equipment. They are mainly used to filter qualified oil products to prevent pollutants from entering the lubricating oil. Due to the preventive purification of lubricating oil products, this type of equipment has low investment and wide benefits. Many users have raised the standard for preventive purification of qualified lubricating oils, and use filtering and purification equipment to prevent new oil or pre-filled oil products.

Re-purification

It refers to the mixing of water, gas, mechanical impurities and other pollutants into the oil, resulting in the unqualified performance of lubricating oil, insulating oil and other oil products; but the composition of the lubricating oil has not changed, and it has not deteriorated. At this time, dehydrating, degassing and removing impurities from the lubricating oil can restore the quality and performance of the lubricating oil, which is the re-purification of the contaminated lubricating oil. Most of the oil filters on the current market are purification and dehydration oil filters designed for contaminated lubricating oil, insulating oil and light fuel oil, but the oil purification capacity and adaptability of various oil filters are different, and they need to be used differently. For example, insulating oil filters and lubricating oil filters must be used differently and cannot be mixed, because of the nature of the oil. Purification and dehydration oil filters are the best tools for the maintenance of oil systems of various lubricating equipment.

Refining and regeneration

It refers to the lubricating oil has turned red and black, and has begun to age and deteriorate, but the corresponding aging index exceeds the standard by a small amount. The re-refining oil filter can be used to filter out the aging and deterioration components in the oil and restore the various performance indicators of the lubricating oil. Since the re-refining oil filter can directly restore the performance of scrapped lubricating oil, it has the most intuitive economic benefits; and it can also be used to prevent the aging and deterioration of lubricating oil. Therefore, although the use cost of the refining oil filter is relatively high, it is still more widely used.

Re-refining

The process similar to oil refining is used to restore the performance of deeply deteriorated lubricating oil to new oil. It is called re-refining. Since the cost of dispersed refining of deeply deteriorated lubricating oil is too high, users are required to hand over the waste oil to the recycling company for recycling. In this type of scrapped oil, heavy metals and colloids are generally seriously exceeded, and chemical additives are also lost. The oil must be re-refined through distillation and then re-blended to make new lubricating oil. This type of equipment is generally called waste oil refining equipment.

Common oils include waste engine oil recycled by 4S stores, blackened lubricating oil mixed and recycled by various industries, etc.
