Abstract

A filter capable of keeping long service life of machine oil mainly comprises an upper cover, a lower casing, a filter body pressing plate, a pressure releasing valve, a pressure releasing clamping spring, a core tube, a filter body and a sealing ring. When the filter works, machine oil flows into an interlayer oil channel arranged between the filter body pressing plate and the upper cover from an oil inlet hole on the upper cover, flows into a cavity formed by the periphery of the filter body of a machine oil purifier and a casing, flows into the core tube after matter such as impurities, moisture, organic acid and the like contained in the machine oil is filtered and absorbed by the filter body, and then flows into a machine from an oil return opening on the upper cover to carry out circulating operation. When the circulating pressure of the machine oil is overlarge, the machine oil can directly flows into the machine from the oil return opening on the upper cover to carry out circulating operation by means of a pressure releasing through hole on the upper cover to press down a pressure clamping spring to open a pressure valve, thereby guaranteeing a normal work lubricating state of the machine and guaranteeing the machine oil after pressure releasing to recover normal purification and circulation process. Compared with the prior art, the filter capable of keeping the long service life of the machine oil has the advantages of effectively absorbing the moisture contained in the machine oil, filtering and storing the impurities contained in the machine oil and effectively prolonging service life of the machine oil.

Description

Keep the long-acting filter of machine oil

Technical field

The utility model 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.

The model utility content

To the deficiency of above-mentioned existing technology, the purpose of the utility model is to strengthen the filtration of machine oil and absorb moisture content with rational structure more and extraordinary filter material, thereby prolongs the Acceptable life of machine oil, bring up to existing 10 times or more than.

The utility model mainly is made up of loam cake, lower casing, filter body pressing plate, Decompression valves, pressure release jump ring, core pipe, filter body, seal ring; Loam cake, lower casing and seal ring then constitute monolithic case; The core pipe places in the core road of filter body; Filter body simultaneously and pressed between filter body pressing plate and upper shell bottom, the upper end of core pipe is placed in the trepanning outside, location of filter body pressing plate, and the pressure release jump ring is placed in the location trepanning of filter body pressing plate again; Decompression valves places its sealing plane of pressure release jump ring upper end to cooperate with the Decompression valves recess of loam cake and the pressure release through hole of loam cake is sealed, and the lower end of core pipe then tightly is placed in outside the positioning table of lower casing.

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 utility model 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.
