Described two machine filter device cores 4 are one-level fine cleaner core, and supercharging filter filter core 3 be a secondary secondary filter filter core, and two oil filter cores 4 and a supercharging to filter between the filter core 3 be series relationship.
Described oil temperature control valve 13 can be dynamically constantly the controller oil temperature in a certain scope.Described piston cooling opening valve 7 and piston cooling control valve 6 are used for the cooling of control piston, and can guarantee that the engine oil pressure of supplying with the piston cooling keeps constant.Described first safety valve 12 is used to realize the oil circuit bypass of supercharging filter filter core 3, and second safety valve 15 is used to realize the oil circuit bypass of oil filter core 4.
Described machine filter device seat 1 is provided with machine oil import 9, first oil outlet 16, second fuel-displaced 18 and the release return opening 17 with the body junction plane, and machine oil filler opening 9 communicates with oil temperature control valve 13 and machine oil cooler oil input channel 25, first oil outlet 16 communicates with main oil gallery 19 after the filtering, second oil outlet 18 communicates with the valve pocket of piston cooling control valve 6, and release return opening 17 communicates with the valve pocket of pressure-limit valve 14.
Described machine filter device seat 1 is provided with before the filtering main oil gallery 19 behind the main oil gallery 8 and filtering, and is provided with the first oil pressure sensor mount inlet 20 before filtering on the main oil gallery 8, and main oil gallery 19 is provided with the second oil pressure sensor mount inlet 21 after the filtering.
Both sides, described machine filter device seat 1 top are respectively equipped with and joining oil outlet flange 22 of machine oil cooler and filler opening flange 23.
During diesel engine work, after entering machine filter device seat 1 from the machine oil of body main oil gallery by the filler opening 9 on machine filter device seat and the body junction plane, when if system's oil temperature is low at that time, then engine oil pressure is higher, oil temperature control valve 13 is opened under higher engine oil pressure effect, make machine oil enter the preceding main oil gallery 8 of filtering, entering two oil filter filter cores 4 then respectively filters, machine oil after the filtration enters main oil gallery 19 after the filtering, then be divided into three the tunnel, first oil outlet 16 on one road slave filter seat junction plane leads to the body main oil gallery, one the tunnel enters supercharging filter filter core 3 carries out entering pressurized machine by pressurized machine oil-feed oil duct 10 behind the cascade filtration, and one the tunnel leads to piston cooling opening valve 7 and piston cooling control valve 6.
The road machine oil that leads to piston cooling opening valve 7 all can make piston cooling opening valve 7 open after filtering under the normal situation of the engine oil pressure in the main oil gallery 19, do not open for lubricated this valve that at first guarantees each component of diesel engine when engine oil pressure is low, piston cooling control valve 6 generally is in normally open, therefore flow through piston cooling opening valve 7 and piston cooling control valve 6 valve pockets from the machine oil in the main oil gallery after the filtering 19 after the second fuel-displaced 18 piston cooling oil duct that enters on the body that machine filter device seat and body mating face are located, remove cooling piston by the piston cooling nozzle oil spout then, when the piston cooling nozzle injection pressure is higher, piston cooling control valve 6 both sides engine oil pressure differences also raise, when the pressure at both sides difference is cooled off control valve 6 initial tension of spring greater than piston, the spool of piston cooling control valve 6 begins to move, and closure piston cools off control valve 6 at leisure, after the oil outlet in piston cooling control valve 6 cavitys is closed, the pressure reduction of piston cooling control valve two 6 sides slowly diminishes again, pressure difference is little when the initial tension of spring, piston cooling control valve 6 begins again to open, piston cooling control valve moves again and again like this, thereby the engine oil pressure of having guaranteed the supply piston cooling nozzle is constant.
If it is higher from the oil temperature of body main oil gallery, then oil temperature control valve 13 is not opened, machine oil flows to machine oil cooler oil input channel 25, oil outlet flange 22 through being connected with cooler enters cooler and cools off, the cooled machine oil filler opening flange 23 through being connected with cooler enters filter cleaner seat 1, ensuing machine oil flow to above the machine oil flow direction opened behind the oil temperature control valve 13 the same.
The working principle and the function of pressure-limit valve 14 are: when the engine oil pressure in the main oil gallery before the filtering 8 is too high; higher engine oil pressure overcomes limiting valve spring elastic force opens pressure-limit valve 14; make machine oil flow back to oil sump through the body return opening, thereby component such as protection filter core and other valve bodies are avoided damaging from unloading port 17.
The working principle and the function of first safety valve 12 are: when supercharging filter filter core 3 stops up, the engine oil pressure that leads to supercharging filter filter core 3 raises, after higher engine oil pressure overcomes first safety valve, 12 spring forces first safety valve 12 is opened, make the machine oil that filters through one-level directly enter pressurized machine through pressurized machine oil input channel 10 by the pressurized machine bypass oil duct on the machine filter device seat 11.The setting of first safety valve 12 and bypass oil duct 11 can protect supercharging filter filter core 3 to avoid damaging, and can guarantee the lubricated of pressurized machine again and cool off unaffected.
The working principle and the function of second safety valve 15 are: when two machine filter device cores 4 stop up, the spring force that higher engine oil pressure overcomes second safety valve 15 is opened second safety valve 15, come from that the machine oil of main oil gallery 9 does not filter by two machine filter device cores 4 before the filtering, and directly enter main oil gallery 19 after the filtering by bypass oil duct 24.The setting of second safety valve 15 and bypass oil duct 24 had both protected two machine filter device cores to avoid damaging, and had guaranteed that again each component of motor obtain lubricated normally and cooling, thereby had guaranteed the normal reliable ground running of motor.
Can monitor before the filtering constantly and the engine oil pressure after the filtering after oil pressure sensor is installed on the first oil pressure sensor mount inlet 20, the second oil pressure sensor mount inlet 21, unusually can be in time these oil filter parts and even diesel engine be safeguarded or keeped in repair if find engine oil pressure.
