Abstract
The utility model relates to a kind of hydraulic oil container return oil filter structures, including oil return filter core, housing cylindrical, hard tube, lower cover, the lower cover and housing cylindrical fixing seal are installed, the hard tube is mounted on center below lower cover, the oil return filter core is mounted on lower cover, it further include mounting base, the mounting base pedestal is hollow disc, top is thin-wall circular tubular, the mounting base centre bore is identical as hard tube bore dia, the mounting base cylindrical shape outer diameter is identical as filter core bore dia, the mounting base is removably mounted between filter core and lower cover, the utility model beneficial effect is: mounting base is removably mounted on lower cover, solve phosphatization, feeling suffocated and hydrops problem in electrophoresis process, more convenient later period cleaning.
Description
Technical field
The utility model relates to a kind of hydraulic system more particularly to hydraulic system oil return oil filtering structures.
Background technique
Fuel tank internal occurs corrosion or gets rusty in order to prevent, and phosphatization can be swum in fuel tank production or electrophoresis process is fuel tank shell
Body metallic matrix provides layer protecting film, and can take the lifting of fuel tank that can take just when fuel tank enters phosphating pond or tiselius apparatus
It hangs or to projecting form；But result is when using projecting, due to mounting base, the structure type meeting of return oil filter bottom plate
Lead to that phenomenon of feeling suffocated can be generated at bottom plate during electrophoresis or phosphating solution enter fuel tank internal, leads to phosphatization or electrophoresis office
Portion's failure, is also easy to produce floating rust, and leading to later period fuel tank, position gets rusty and seriously affects fuel tank internal cleannes index herein.
When using positive hang, fuel tank phosphatization or electrophoresis are complete leave phosphating pond or tiselius apparatus when, the phosphating solution of fuel tank internal
Or electrophoresis liquid can be flowed out from fuel tank fuel outlet or Butterworth Hatch, but had at oil filter bottom plate and mounting base and accumulated to obtain phosphating solution
Or electrophoresis liquid, need to draw residual liquid at this time using vacuum machine, not only waste of time, often result is still drawn unclean.
Simultaneously for when engineering machinery oil tank is maintained in field, this welding monolithic construction will lead to the accumulation of oil return shell
It is extremely difficult that pollutant, which carries out cleaning,.
Utility model content
The technical issues of the utility model solves is: fuel tank phosphatization at mounting base and oil filter lower cover, in electrophoresis process
Feel suffocated and hydrops problem and later period oil tank cleaning internal contamination object cleaning problem.
Provided technical solution is the utility model to solve above-mentioned technical problem:
A kind of hydraulic oil container return oil filter structure, including oil return filter core, housing cylindrical, hard tube, lower cover, the lower end
Lid is installed with housing cylindrical fixing seal, and the hard tube is mounted on center below lower cover, and the oil return filter core is mounted on lower end
It covers, it is characterised in that: further include mounting base, the mounting base pedestal is hollow disc, and top is thin-wall circular tubular, the peace
Dress seat centre bore is identical as hard tube bore dia, and the mounting base cylindrical shape outer diameter is identical as filter core bore dia, and the mounting base can
Disassembly is mounted between filter core and lower cover.
Mounting base pedestal outer is provided with n groove, and n is more than or equal to 2, and lower cover place corresponding with groove is opened
There is bolt hole, the mounting base is fixed in bolt hole by bolt by groove.
The mounting base bottom is provided with annular groove, places o type circle in the groove.
The utility model beneficial effect is: mounting base is removably mounted on lower cover, in solution phosphatization, electrophoresis process
Feel suffocated and hydrops problem, be more convenient the later period cleaning.
Detailed description of the invention
Fig. 1 is hydraulic oil container return oil filter structural schematic diagram；
Wherein, 1, oil return filter core, 2, housing cylindrical, 3, hard tube, 4, mounting base, 5, o type circle, 6, lower cover, 7, bolt, 8,
Centre bore.
Specific embodiment
Referring to attached drawing, a kind of hydraulic oil container return oil filter structure, including oil return filter core 1, housing cylindrical 2, hard tube 3, under
End cap 6, the lower cover 6 are installed with 2 fixing seal of housing cylindrical, and the hard tube 3 is mounted on center under lower cover 6, and described time
Oily filter core 1 is mounted on lower cover 6, further includes mounting base 4, and 4 pedestal of mounting base is hollow disc, and top is thin-walled cylinder
Shape, 4 centre bore 8 of mounting base is identical as 3 bore dia of hard tube, the cylindric outer diameter of the mounting base 6 and 1 bore dia of oil return filter core
Identical, the 4 pedestal outer of mounting base is provided with n groove, and n is more than or equal to 2, and mounting base 4 is mounted on oil return filter by bolt 7
Between core 1 and lower cover 6, o type circle 5 is installed in the annular groove below mounting base 4.
After completing fuel tank phosphatization or electrophoresis process, 5 groove of o shape circle that o shape circle 5 is mounted below 4 pedestal of mounting base
It is interior, mounting base 4 is then placed on filter lower cover 6 above and ensures that the two centre bore 8 is aligned, then puts bolt 7 into
It is screwed into 6 bolt hole of lower cover in 4 submounts groove of mounting base, mounting base 4 is fixed on above bottom plate 6.Then can
Subsequent assembly manipulation is carried out above so that oil return filter core 1 is mounted on mounting base 4；Fuel tank mounting base 4 when carrying out phosphatization or electrophoresis
Without installation, avoids just to hang when phosphatization or electrophoresis in this way, hangs upside down the filter housings as caused by the presence of mounting base 4
Occur at lower cover 6 feel suffocated, hydrops problem.
