Abstract
The utility model provides a dig hydraulic tank's oil return a little and strain lid, including the lid with lead back oil pipe, seted up the oil pipe through -hole on the lid, lead back oil pipe and passes the oil pipe through -hole, back lead oil pipe and welds on the lid, lead back oil pipe's first time oil pipe of upper portion fixedly connected with and second time oil pipe, the lower extreme of leading back oil pipe is connected with the oil return filter core, first time oil pipe, second time oil pipe and oil return filter core all with lead back oil pipe and communicate, first time oil pipe and second time oil pipe are located the top of lid, the oil return filter core is located the below of lid. The utility model discloses a main time oil pipe of integration on the lid for hydraulic tank is last need not to arrange the oil return opening, has saved hydraulic tank's space, has satisfied the demand of digging little space layout hydraulic tank a little. The lower extreme that owner on the lid returned oil pipe is connected with the oil return filter core, need not set up the oil return chamber in hydraulic tank, just can realize the filtration of hydraulic oil, the space of having practiced thrift hydraulic tank.
Description
Technical field
This utility model relates to micro-case lid field digging hydraulic oil container, is specifically related to a kind of micro-oil return filter cover digging hydraulic oil container.
Background technology
The structure of existing micro-case lid dug on hydraulic oil container is a circular lid mostly, or increases on the lid of circle
Adding a breather valve mounting seat, the effect of case lid is intended merely to the filter element installing hole of leakproof fuel cell, and case lid is to hydraulic oil container
Limited use, it addition, oil return opening needs to be arranged on the casing of hydraulic oil container, takies the space of casing, it is impossible to meet micro-dig little
The demand of fuel tank is arranged in space, and hydraulic oil container needs have single oil return cavity could realize hydraulic pressure oil filtration, and this allows for
The complicated structure of hydraulic oil container, it is the most convenient to install.
Utility model content
For the problem that the lid effect on existing hydraulic oil container is single, this utility model provides a kind of micro-hydraulic oil container that digs
Oil return filter cover.
The technical scheme that this utility model employing is following:
A kind of micro-oil return filter cover digging hydraulic oil container, including lid and main oil return pipe, described lid offers oil pipe through hole, institute
Stating main oil return pipe and pass oil pipe through hole, main oil return pipe is welded on lid, and the top of described main oil return pipe is fixedly connected with first time
Oil pipe and the second oil return pipe, the lower end of main oil return pipe connects oil return filter element, described first oil return pipe, the second oil return pipe and oil return
Filter element all connects with main oil return pipe, and described first oil return pipe and the second oil return pipe are positioned at the top of lid, and described oil return filter element is positioned at
The lower section of lid.
Preferably, described lid is generally circular in shape.
Preferably, described lid is further opened with the hydraulic-oil filling mouth facilitating hydraulic oil to add.
Preferably, it is threaded connection between described main oil return pipe and oil return filter element.
This utility model has the beneficial effect that
Micro-oil return filter cover digging hydraulic oil container that this utility model provides, by main oil return pipe integrated on lid so that liquid
Need not on force feed case arrange oil return opening, save the space of hydraulic oil container, meet micro-need digging little space layout hydraulic oil container
Ask；The lower end of the main oil return pipe on lid connects oil return filter element, it is not necessary to arrange oil back chamber in hydraulic oil container, it is possible to real
Existing hydraulic pressure oil filtration, has saved the space of hydraulic oil container.It addition, hydraulic-oil filling mouth facilitates personnel to fill hydraulic pressure in fuel tank
Oil.The design of this oil return filter cover is simple, and structural safety is reliable, plays good effect in actual applications.
Accompanying drawing explanation
Fig. 1 is the structural representation of micro-oil return filter cover digging hydraulic oil container.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is specifically described:
In conjunction with Fig. 1, a kind of micro-oil return filter cover digging hydraulic oil container, including lid 1 and main oil return pipe 2, being shaped as of lid 1 is round
Shape.
Wherein, lid 1 offering oil pipe through hole, main oil return pipe 2 is through oil pipe through hole, and main oil return pipe 2 is welded on lid 1
On, the top of main oil return pipe 2 is fixedly connected with the first oil return pipe 3 and the second oil return pipe 4, the first oil return pipe 2 and the second oil return
Pipe 3 is positioned at the top of lid 1.
This oil return filter cover is by integrated main oil return pipe on lid so that need not on hydraulic oil container arrange oil return opening, saves
The space of hydraulic oil container, meets and micro-dig little space and arrange the demand of hydraulic oil container.
The lower end of main oil return pipe 2 connects oil return filter element 5, is threaded connection between main oil return pipe 2 and oil return filter element 5, returns
Oil filter element position 5 is in the lower section of lid 1.
First oil return pipe the 3, second oil return pipe 4 all connects with main oil return pipe 2 with oil return filter element 5.
The hydraulic-oil filling mouth 6 facilitating hydraulic oil to add it is further opened with on lid 1.
The lower end of the main oil return pipe on lid 1 connects oil return filter element 5, it is not necessary to arranges oil back chamber in hydraulic oil container, passes through
Oil return filter element 5 just can realize hydraulic pressure oil filtration, has saved the space of hydraulic oil container.
The design of this oil return filter cover is simple, and structural safety is reliable, plays good effect in actual applications.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this skill
Change that the technical staff in art field is made in essential scope of the present utility model, retrofit, add or replace, also should belong to
Protection domain of the present utility model.
