Discharge.
In the present invention, owing to U-shaped separation of particles module 3 is to solid particle separation of polymeric effect in fluid, at U-shaped microgranule
In the fluid in separation module 3 exit, the fluid at the center only small particle microgranule Han trace, this part fluid is from inner core oil inlet pipe 12
It is flowed into inner core 15 and carries out high-precision filtration；And the fluid of near-wall is rich in aggregated particles, this part fluid passes through oil returning tube
Oil inlet pipe 22 enters oil returning tube 7, then flows back to fuel tank 11 through the oil drain out 10 of overflow valve 8, thus realizes solid particle by particle
Footpath shunting filtering.Herein, oil returning tube 7 and overflow valve 8 serve aforesaid macrofiltration, thus save filter number, fall
Low system cost and complexity.The automatically controlled set screw 9 of overflow valve 8 is used for regulating oil pressure relief, is adjusted to by its pressure slightly
Less than pressure at filtering outlet, to ensure inner core 15 filtering traffic.
It addition, traditional filter mainly uses cake filtration mode, during filtration, filtrate is perpendicular to filter element surface stream
Dynamic, trapped solid particle forms filter cake progressive additive, and the rate of filtration is gradually reduced the most therewith, until filtrate stops stream
Go out, reduce the service life of filter element.In this present invention, carry the filtrate of small particle microgranule from inner core oil inlet pipe 12
Flowing into the helical flow path 17 of inner core 15 in the way of tangential influent stream, inner core 15 wall of helical duct 17 side is high-precision filter element
18, filtrate is close to filter element 18 surface under the influence of centrifugal force, and filtrate is parallel to the surface of filter element 18 and quickly flows, after filtration
Hydraulic oil is then perpendicular to filter element 18 surface direction and flows out to urceolus 19, and the direction of the two flowing is orthogonal staggered, therefore claims it
Filter for cross flow.The quickly flowing of filtrate is applied with shearing to the microgranule being gathered in filter element 18 surface and sweeps stream effect, thus presses down
Having made the increase of filter cake thickness so that rate of filtration near constant, filter pressure also will not raise with the passing of time, filter element
Service life thus increase substantially.Along with the accumulation of filtration time, it is deposited on the pollution granule bottom inner core 15 inverted round stage
Being stepped up, the rate of filtration slowly declines, and in inner core 15, unfiltered filtrate rises along the hollow cylinder 16 at center, now, and pressure
Difference indicator 14 works, and monitors the change of its pressure, that is the stopping state of filter element 18 bottom inner core 15, if exceeding threshold value, then
Regulate automatically controlled set screw 9 and reduce oil pressure relief, and open check-valves 24 simultaneously, make bottom inner core 15 containing more pollution granule
Filtrate is discharged to oil returning tube 7 by inner core oil exit pipe 23 under differential pressure action, it is to avoid bottom, filter element 18 blockage deteriorates, from
And extend filter element 18 service life.
