Description
Technical field
The utility model relates to a kind of cleaner, is specifically related to a kind of spin-on filter, is used to filter the various impurity in the machine oil.
Background technology
Cleaner be with removing metal fragment and various impurity in the oil, make oil reach certain cleannes, prevent the device wearing and tearing, protection main frame parts prolong its service life.Oil filter can be divided three classes by work principle of filter: mechanical separation, centrifugation and magnetic absorption.Pure machinery separates the common grid that has and filters, and the aperture of certain size is arranged on surface of filter medium, the solid particles in the machine oil, and size is just stopped on the filter material outer surface greater than aperture; Centrifugation is to make machine oil pass through a high speed rotor rotated, and well cuts is subjected to centrifugal action to be thrown to rotor inner wall, thereby separates from machine oil; Magnetic absorption is to utilize permanent magnet that the irony particle in the machine oil is adsorbed, and does not allow their circulate back and forth in machine oil, the harm parts.
More all kinds of cleaners, mechanical isolating construction is simple, adopt the multiple filtration net to filter, but when the pressure into and out of oil did not reach certain value, the by-passing valve of cleaner can be opened, and machine oil directly flows into main oil gallery through by-passing valve just without filtration.When containing oarse-grained impurity in the oil, when filtering, cause bulky grain to stop up space between fiber easily, influence later result of use thereby filter area is little, more cause a large amount of wastes during renew cartridge, there is the also uppity technical problem of general assembly cleannes.Magnetic absorption only is fit to filter ferromagnetism impurity, and filtration types is comparatively single.Centrifugal separation, oil by nozzle produces a moment of reaction, drive rotor rotation, oil in the rotor is isolated solid impurity under centrifugal action, accumulate on the rotor inner wall, the rotor center oil partly cleaning that becomes, from nozzle flow oil return drain pan, that utilizes centrifugal force and screen pack combines removing impurities, and effect is preferable.
Now in the technology, spin-on filter such as the disclosed spin-on oil filter of Chinese utility model (CN2782944Y), constitute by base, shell, armature spindle, rotor block mechanism, rotor block mechanism is socketed on the armature spindle, and can freely rotate, rotor block mechanism is made up of upper and lower bearing, base plate, interior deflector, mozzle, rotor cap, and mozzle is arranged on the center axial location of rotor cap, and it is fixed with upper and lower bearing in two ends up and down.Its operation principle is: the machine oil of engine flows into base from the bottom from fuel feed hole, and the oilhole on armature spindle sprays, enter rotor block mechanism inner chamber along the mozzle inwall, participate in the high speed rotation of rotor mechanism, under the centrifugal inertial force effect that rotation is produced at a high speed, contained granule foreign is deposited in rotor block mechanism inwall in the machine oil, and the machine oil after filtering will be injected in the reaction force of borrowing oily stream to spray on the base and continue to promote the rotation at a high speed of rotor block mechanism do along two nozzle ejections of rotor block mechanism.Yet, as described herein, when engine drives to certain fare register, the suitable quantity of impurity Ji Dian after the in-house filtration of rotor block makes the weight of rotor block mechanism increase, and the upwards motive force that oil stream sprays can not overcome whole gravity, the filtration of cleaner will slowly be lost, and need the whole rotor block of replacing mechanism, and it is higher to change frequency, waste to material is bigger, and use cost is higher; In addition, this structure is to rely on oil pressure to finish oil-feed and as rotary motive power, and oil pressure is stable all will directly to be influenced fuel-displacedly, and simultaneously only according to borrowing oil pressure as power, the turning power deficiency also will directly cause the efficient and the effect of centrifugal removing impurities; Also have, oil-out is arranged at the interior ring place of rotor block structure machine, and between the impurity of rotor internal deposition without any spacer assembly, can not get rid of the possibility of stopping up oil-out.Therefore, present spin-on filter structure is perfect not enough, needs to do further to improve.
