Description

A kind of liquid cleaner

Technical field:

The present invention relates to cleaner field, especially a kind of liquid cleaner that is provided with by-passing valve and oil-out check-valves and/or magnet.

Background technology:

At present, need fluid lubrication or utilizing fluid fuel to support in the plant equipment of work by combustion, the fluid such as lubricating oil and fuel oil using, in transport and use procedure, there are a certain amount of acting accessory substance and other objectionable impurities in capital, especially the metal impurities that wear and tear from equipment mix therein, impurity can cause wearing and tearing to equipment, even stop up fluid passage, reduction equipment service efficiency, shorten service life of equipment, in order to tackle the objectionable impurities filtering in fluid, avoid impurity to cause damage to equipment, protection equipment performance optimum performance, extension device service life.Cleaner is set on fluid passage to be absolutely necessary.Existing liquid cleaner primary structure comprises the filter medium assembly in shell, housing cover, housing, between filter medium assembly and oil-in, be provided with check-valves, below filter medium assembly, being provided with by-passing valve, mainly there are several large defects below in existing liquid cleaner.

First, in existing lubricating oil purifier, when for fear of plant equipment, in cold start-up lubricating oil viscosity, large or filter medium is blocked, cause plant equipment dry friction, rear end at filter medium is provided with by-passing valve, to guarantee that, in the time that filter medium is blocked, lubricating oil can loop back plant equipment through by-passing valve, for plant equipment provides proper lubrication.But in actual use,, owing to by-passing valve being arranged on to the rear end of filter medium, when filter medium or cleaner are when blocked, the resistance of cleaner inside will increase, and causes by-passing valve to be difficult to be opened.Therefore, very easily cause filter case and sealing ring to be suppressed quick-fried, produce oil leakage phenomenon, or filter medium is suppressed brokenly, cause losing filtration and/or make the clogging grease channel of broken filter parts, cause plant equipment lubricated owing to lacking, and frayed or produced by the phenomenon of locking.And in existing liquid cleaner, in the time that or filter medium large by filter fluid viscosity under low-temperature condition is blocked in use for some time, even in the situation that by-passing valve can be by smooth opening, also first to be passed through between the inwall of filter case and the outer surface of filter medium by filter fluid, then the by-passing valve gadgetize equipment of flowing through.The effective filtration that not only be can not get filter medium by filter fluid now, and also can be filtered media filtration out by original, and be deposited on the large granular impurity on filter medium outer surface, and take in plant equipment through by-passing valve, cause larger uninterrupted wearing and tearing to plant equipment.

Second; in existing liquid cleaner, be drained for fear of plant equipment cleaner after long-time shutdown, while causing next plant equipment to restart; lubricating oil is supplied with to be lagged behind to cause plant equipment dry friction and/or fluid fuel is supplied with and is lagged behind, and extension device start-up time.Oil-in place at cleaner is typically provided with oil-in check-valves; avoid cleaner to be drained; be used for guaranteeing that plant equipment, can be within the shortest time in the time that start next time, the lubricated or fluid fuel support equipment that obtains retaining in cleaner lubricating oil starts acting.But due in existing liquid cleaner, be conventionally all only provided with oil-in check-valves at the oil-in place of cleaner, and do not set out hydraulic fluid port check-valves at oil-out place.Will cause like this lubricating oil or fluid fuel in cleaner, flow back in the oil sump or fuel tank of plant equipment through oil-out by filter medium micropore, and cleaner is drained, cause plant equipment in next time during from new startup, because lubricating oil or fluid fuel are supplied with and are lagged behind, cause dry friction and/or start-up time to be extended to plant equipment, cause irreversible infringement to plant equipment.So the oil-in check-valves only arranging at oil-in place just performs practically no function, it does not only have non-return effect, and also can increase production cost and be formed resistance to filtering fluid.

The 3rd, existing machine oil or fuel filter, conventionally be all the objectionable impurities using in single papery filter medium filtering fluid, but in the time of actual design, can not form under the prerequisite of resistance being filtered fluid in order to ensure filter medium, must intentionally filter paper pore size be amplified, do cost with sacrificial section filter effect.So just cause again existing filter medium, the best ability that also can only be designed into 60% left and right impurity in filtering fluid.This point just can be confirmed in the existing machinery industry standard JB/T5088.2-2008 of China " internal combustion engine rotary mounting engine oil filter Part II, test method ".So existing liquid cleaner can be described in actual use, even under the situation of not opening at by-passing valve, also having 40% left and right to be less than the objectionable impurities of filter medium micropore can not be by effective filtering, in this section can not be by the objectionable impurities of effectively filtering, because the Ferromagnetic Impurities under wearing and tearing in plant equipment is relatively tiny, so in the majority with Ferromagnetic Impurities, and the hardness of Ferromagnetic Impurities must exceed the hardness of other composition objectionable impurities, its wearing and tearing that cause to plant equipment are also maximum.

In sum, existing liquid cleaner, the impurity that is greater than and is less than its filter medium micropore is not all had to permanent filtration, can only equate with its filter medium micropore those, and the impurity that can be embedded in filter medium micropore plays permanent filtration.Therefore can illustrate, existing liquid cleaner not only filtering efficiency is extremely low, and also exists above-mentioned many design defect.As do not taked a kind of rationally effective method, solve the defect of existing liquid cleaner, it will cause plant equipment by instead by multiple dry friction or because lack lubricated and by locking, and entered the large granular impurity of plant equipment through by-passing valve, especially plant equipment is endangered to maximum Ferromagnetic Impurities and bring uninterrupted wearing and tearing.Owing to will be changed original design parameter of plant equipment by the wearing and tearing of unlubricated friction scrape along repeatedly, oil consumption, noise and the exhaust emissions of plant equipment are strengthened, compression ratio reduces, power declines, lower exhaust increase, burn oil, the maintenance frequency of increase plant equipment, the life cycle of shortening lubricating oil and cleaner, cause plant equipment to be scrapped in advance, increase and pollute to environment, bring waste to resource, for consumer brings many correlative charges that should not produce.

This is just badly in need of a kind ofly can solving the liquid cleaner of described problem above.

Summary of the invention:

Object of the present invention, in order to provide one can effectively promote filtering efficiency, can effectively avoid again the explosive shell of cleaner, quick-fried core, quick-fried envelope, leakage of oil, easily stop up oil circuit, easily be drained, easily make fuel feeding to be lagged behind, easily cause equipment by dry friction, easily cause plant equipment by locking, especially can effectively avoid large granular impurity to be brought plant equipment by filter fluid through by-passing valve secondary, and Ferromagnetic Impurities cause a kind of liquid cleaner of the phenomenon generations such as uninterrupted wearing and tearing to plant equipment.
