Abstract
The invention relates to a filter keeping long action of engine oil. The filter mainly comprises an upper cover, a lower casing, a filter body pressure plate, a pressure relief valve, a pressure relief snap spring, a core pipe, a filter body and a sealing ring. When the filter works, the engine oil enters into an interlayer oil passage between the filter body pressure plate and the upper cover from an oil inlet hole of the upper cover and further enters into a cavity formed by the periphery of the filter body of an engine oil purifier and a housing, impurities, water, organic acids and other substances, which are contained in the engine oil, are filtered and absorbed by the filter body, and then the engine oil enters into the core pipe and finally enters into a machine from an oil return port of the upper cover for circulating work; and when the circulating pressure of the engine oil is too large, the engine oil can press down the pressure snap spring through a pressure relief through hole of the upper cover, open a pressure valve and then directly enters into the machine through the oil return port of the upper cover for circulating work, so that the normal working lubrication state of the machine can be ensured, and the engine oil after pressure relief can recover the normal purification circulation process. Compared with the prior art, the filter disclosed by the invention has the benefits that the water in the engine oil can be effectively absorbed, the impurities contained in the engine oil can be filtered out and the effective service life of the engine oil can be further prolonged.
Description
Technical field
The present invention is a kind of oil strainer, particularly a kind of long-acting filter of maintenance machine oil that can permanently effective filtration machine oil.
Background technique
The machine oil that uses in the various machinery, it is lubricated that effect mainly contains one, between moving parts, provides film lubrication to reduce friction and to wear and tear; The 2nd, cooling is taken away the heat cooling action as thermal medium from critical surface; The 3rd, sealing, filling casing wall, the injustice place on valve stem surface and in the oil sealing of turbosupercharger, sealing; The 4th, cleaning is taken back sump through flowing of machine oil with the carbide on the part, greasy filth, the logical circulation of wear metal particle, and is unlikely at part surface formation incrustation; The 5th, damping and buffering effect, particularly high pressure component are like gear and push rod etc.; The 6th, anti-oxidation and corrosive action shield to part.Machine oil is the work during through one section in machine, has brought into play after the above-mentioned function contaminated and the mistake effect need be changed.In order to prolong the working life of machine oil, the most frequently used method is to use oil strainer, returns machine relaying supervention behind the contaminant filter that oil circulation is taken back and waves due function.The oil strainer that uses at present is main with filtration larger particles impurity mainly all, and shortcoming one is can't get rid of and generate organic acid for moisture content the part machine is produced corrosion, and this also is the main cause that causes the machine oil premature failure; Another shortcoming is after filter core is blocked, and the bypass valve in the filter is opened, and machine oil does not just filter and directly gets in the machine, still takes back the impurity that has originally filtered out synchronously in the machine simultaneously, causes machine parts to quicken to waste damage.
Summary of the invention
To the deficiency of above-mentioned existing technology, the objective of the invention is to strengthen the filtration of machine oil and absorb moisture content, thereby prolong the Acceptable life of machine oil with rational structure more and extraordinary filter material, bring up to existing 10 times or more than.
The present invention mainly comprises loam cake, lower casing, filter body pressing plate, Decompression valves, pressure release jump ring, core pipe, filter body, seal ring composition.Wherein loam cake, lower casing and seal ring are formed the monolithic case of oil strainer; The filter body place shell and and shell between be fixed with certain space; The core pipe places the core road of filter body; The lower end is enclosed within on the core pipe positioning table of lower casing; The location trepanning that the upper end then is enclosed within filter body pressing plate outward then, the pressure release jump ring is placed in the location trepanning of filter body pressing plate again, Decompression valves places pressure release jump ring upper end and cooperates with the Decompression valves recess of loam cake.During work; Machine oil gets into the external week of filter of the interlayer oil duct entering machine oil purifier between filter body pressing plate and the loam cake and the cavity that shell forms by the oil inlet hole of loam cake; Logical again filter is filtered materials such as contained impurity own, moisture content, organic acid and is absorbed back entering core pipe, and last return opening by loam cake gets into and carries out periodic duty in the machine; When oil circulation pressure is excessive; Then machine oil can press down the pressure jump ring of support Decompression valves through the pressure release through hole of loam cake and open pressure valve directly through circuit work in the return opening entering machine of loam cake; To guarantee the proper functioning lubricating status of machine, originally filter and reside in the impurity in the machine oil purifier and then can not taken back in the machine again part is not worn and torn because be present in the bottom; Machine oil after the pressure release then can recover normal decontamination cycle process once more.
The beneficial effect that the present invention compared with prior art has is effectively to absorb moisture content and filtering in the machine oil to receive and deposit impurity, thereby prolongs the Acceptable life of machine oil.
