Therefore, the lubricating oil needs to be purified or filtered when in use.

Currently common oil purification techniques include mechanical, centrifugal, electrical charge, and the like. Mechanical type absolute oil filters fluid through mechanical mixed flow subassembly, generally can effectively purify medium-sized and large-scale particulate matter, but can't catch the particulate matter that is less than the filter screen, and littleer particulate matter makes the filter jam easily, needs often to change the mixed flow subassembly, and use cost is high. Centrifugal oil purification also fails to filter out fine particulates. The principle of the charge type oil purification mode is as follows: the oil with impurities is divided into two paths in the device, and the two paths are respectively provided with a charge injection device, wherein one path is injected with positive charges, the other path is injected with negative charges, and pollution particles with the positive charges and the negative charges can be mutually aggregated and grown up when being mixed. The mixed oil is introduced into a filtering device, and the agglomerated particles are easily captured and filtered. Therefore, the charge type oil purifier has a good effect of purifying small particles.

Therefore, there is a need for a charge flow mixing device and an oil filtering system to solve the above problems.
