Internal tandem type lubricating oil filter capable of removing water and scrap iron

Abstract

The invention relates to a lubricating oil filter, in particular to an internal tandem type lubricating oil filter capable of removing water and scrap iron. The problems that the quality of lubricating oil is reduced, the service life is shortened, the failure rate of oil machinery is increased and the existing filters connected in series or in parallel through pipelines are large in size, increased in leakage probability and long in installation time due to the fact that insoluble precipitates in the form of scrap iron and oil sludge are continuously increased in the use process of the lubricating oil are solved. The filter comprises a cylindrical shell and a filter element assembly in the shell. An oil inlet and an oil outlet are formed in the upper end face and the lower end face of theshell respectively. The lubricating oil filter is characterized in that the filter element assembly comprises a first filter element, a middle partition plate, a middle metal supporting net and a second filter element which are sequentially arranged from top to bottom; a first partition plate is arranged at the upper middle position of a first hollow cylinder in the first filter element; a permanent magnet is fixed on the lower surface of the first partition plate; an oil passing hole is formed in the middle partition plate; and a carbon powder polymer is placed on one side of the closed endof the upper end of the second hollow cylinder in the second filter element.

Description

technical field [0001] The invention relates to a lubricating oil filter, in particular to an inner series lubricating oil filter capable of removing water and iron scraps. Background technique [0002] During the use of lubricating oil, due to the continuous accumulation of iron filings, incomplete combustion products, oxygen-containing sulfur compounds and oxygen-containing compounds formed by the oxidation of the lubricating oil itself, as well as the immersion of water molecules, iron filings and sludge-like insoluble deposits are caused. (including paint film, carbon deposits and sludge) continue to increase, the quality of lubricating oil decreases, and the service life of lubricating oil is shortened. In the long run, the failure rate of oil-using machinery is increased. [0003] In addition, the service life of the existing filters is limited. In order to increase the service life, the common solution is to connect two or more filters in series or in parallel through...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an internal series lubricating oil filter capable of removing water and iron filings, so as to solve the problem of reduced lubricating oil quality due to the continuous increase of iron filings and sludge-like insoluble deposits during the use of lubricating oil. The service life is shortened, the failure rate of oil-using machinery is increased, and the existing filters connected in series or in parallel through the pipeline have technical problems such as large volume, increased leakage probability, and long installation time
