Description

Secondary cylinder type hydraulic oil filter
Technical field
The utility model belongs to hydraulic oil filter field, is specifically related to a kind of secondary cylinder type hydraulic oil filter.
Background technique
Hydraulic shovel is one of main type of engineering machinery.Along with to excavator in working efficiency, save the energy, operate light, safety and comfort, raising that the various aspects of performance such as reliability and durability requires, the requirement in the hydraulic parts life-span of excavator is improved gradually.Excavator is due to work under bad environment, and operating mode is special, and hydraulic oil oil return is impure more, needs accurately to filter, and traditional filter type is because structural limitations, and filter precision is not high, affects the working life of excavator hydraulic parts.
Model utility content
The purpose of this utility model is to provide a kind of secondary cylinder type hydraulic oil filter, and solve traditional filter type because structural limitations, filter precision is not high, affects the problem in the working life of excavator hydraulic parts.
The utility model relates to a kind of secondary cylinder type hydraulic oil filter, comprise housing, enclosure interior is provided with filter core, is provided with oil pocket one and oil pocket two in housing, and oil pocket one is communicated with oil pocket two-way oil channel, the top of oil pocket one has filler opening, the top of oil pocket two has oil outlet, and filler opening bottom is provided with one-level filter core, is connected bottom one-level filter core by spring one with the bottom of housing, the oil outlet place of oil duct is provided with secondary filter core, and the bottom of secondary filter core is connected with housing sidewall by spring two.
The inner walls that filler opening is other is provided with circular groove one, and the top of one-level filter core is placed in circular groove one, prevents filter core wobble effects filtering effect in working procedure.
The inner walls that oil duct oil outlet is other is provided with circular groove two, and the top of secondary filter core is placed in circular groove two, prevents filter core wobble effects filtering effect in working procedure.
Compared with prior art, the utility model has the advantage of:
Structure is simple, by secondary filter element filtering, makes filter precision higher, improves the working life of excavator hydraulic parts, prevents plugged filter from causing hydraulic oil cannot oil return, plays safety effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, filler opening, 2, circular groove one, 3, one-level filter core, 4, housing, 5, oil outlet, 6, secondary filter core, 7, oil pocket two, 8, spring two, 9, circular groove two, 10, oil duct, 11, spring one, 12, oil pocket one.
Embodiment
Contrast accompanying drawing below, embodiment of the present utility model is described in further detail.
The utility model relates to a kind of secondary cylinder type hydraulic oil filter as shown in Figure 1, comprise housing 4, housing 4 inside is provided with filter core, oil pocket 1 and oil pocket 27 is provided with in housing 4, oil pocket 1 is communicated with by oil duct 10 with oil pocket 27, the top of oil pocket 1 has filler opening 1, the top of oil pocket 27 has oil outlet 5, filler opening 1 bottom is provided with one-level filter core 3, be connected with the bottom of housing 4 by spring 1 bottom one-level filter core 3, the oil outlet place of oil duct 10 is provided with secondary filter core 6, and the bottom of secondary filter core 6 is connected with housing 4 sidewall by spring 28.
Housing 4 inwall that filler opening 1 is other is provided with circular groove 1, and the top of one-level filter core 3 is placed in circular groove 1, prevents filter core wobble effects filtering effect in working procedure.
Housing 4 inwall that oil duct 10 oil outlet is other is provided with circular groove 29, and the top of secondary filter core 6 is placed in circular groove 29, prevents filter core wobble effects filtering effect in working procedure.
When filter normally works, hydraulic oil enters from filler opening 1, successively by one-level filter core 3 and secondary filter core 6, flows out, realize cascade filtration from oil outlet 5, improves filter precision.When one-level filter core 3 blocks, hydraulic fluid pressure raises, and Compress Spring 1 forms path, and hydraulic oil, through secondary filter core 6, flows out from oil outlet 5, realizes filtering.When one-level filter core 3 and secondary filter core 6 all block, hydraulic fluid pressure raises, and Compress Spring 1 and spring 28 form path, and hydraulic oil flows out without filtration, prevents plugged filter from causing hydraulic oil cannot oil return, plays safety effect.
In sum, the utility model structure is simple, by secondary filter element filtering, makes filter precision higher, improves the working life of excavator hydraulic parts, prevents plugged filter from causing hydraulic oil cannot oil return, plays safety effect.
