Description
Technical field
The utility model relates to a kind of filter device with pressure gauge, it is mainly used for lubrication oil filtration and pressure is shown.
Background technique
Filtering table is generally arranged in existing lubricating oil filter in shell, and the solid impurity in lubricating oil is blocked in filter
Disk oil inlet side.Its major defect is embodied in: the first, filter disc charge and discharge operations are complicated, clear up inadequate when filter or replacement filter disc
It is convenient；The second, filter disc disk and lubricating oil flow to orthogonal, larger by flow at high speed lubricating oil impact force, therefore to filter disc
Pressure-resistant performance requirement it is harsh；Third, the sticky filter residue that the accumulation of back casing inner wall is used for a long time are difficult to.
On the other hand, existing lubricating oil filter is without pressure-display device, for showing lubricating oil supply system pipeline
The pressure gauge of interior fluid pressure numerical value is typically mounted on the pipeline being connected in series with filter.In some Special use places, than
In compact lubricating utensil, lubricating oil pressure gauge limited space, the existing profit without pressure gauge are installed on oil feed line
Oil filter is difficult to adapt to installation requirements.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of compact-sized, filtering accuracy height, receiving pressure
Height, filter element replacing facilitate and have the lubrication oil filtration and pressure-display device of pressure display function.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme:
A kind of lubrication oil filtration and pressure-display device, including tubular shell are equipped with filter core, feature in tubular shell
It is: offers the mounting hole that inner end is communicated with shell inner cavity on the tube wall of tubular shell and is fixedly installed with pressure at the mounting hole
Power meter connector is equipped with pressure gauge in pressure tapping；The filter core includes filter screen joint, and the inner end of filter screen joint is fixed with
Tubular filter screen, the outer end of tubular filter screen are fixed with strainer end socket；The external screw thread and tubular shell opened up on the outer wall of filter screen joint
Internal screw thread is worked in coordination connection；The oil suction chamber being sequentially communicated, adapter cavity and pressure gauge installation cavity are offered in pressure tapping；Pressure
The inner wall of power table installation cavity offers internal screw thread and the external screw thread of pressure gauge oil inlet pipe is cooperatively connected；Oil suction chamber and the shell inner cavity
It communicates, adapter cavity is communicated by pressure gauge installation cavity with pressure gauge oil inlet pipe.
The diameter of adapter cavity is less than the diameter of oil suction chamber；The diameter of adapter cavity is less than the diameter of pressure gauge installation cavity.
Filter screen joint offers interior six holes.
The plain cushion of sealing is fixedly installed between pressure tapping and the mounting hole.
Compared with prior art, the utility model has the positive effect that:
The first, by rotary sieve connector, element kit easily can be dismantled or install, in addition, due to filter residue quilt
It is blocked in interior, is not contacted with shell tube wall, therefore no longer needs to clear up tube wall, therefore the utility model has entirety
The convenient and fast outstanding feature of filter element replacing easy to maintain.
The second, oil flow direction is the axial direction of tubular shell, and disengaging strainer lubricating oil flow direction is the diameter of tubular shell
To lubricating oil flow is smaller to strainer impact force, and strainer pressure resistance performance is more preferable.
Third, filter device carry pressure gauge, when by it loaded in compact lubrication oil supply equipment, without in oil feed line
Upper in addition setting pressure-display device, provides optimized Selection accessory for compact lubrication oil supply Equip- ment manufacture and installation.
4th, the lubricating oil that high speed enters from shell inner cavity successively passes through three relatively thick, relatively thin and then thicker chambers, and flow velocity is bright
It is aobvious to reduce, to alleviate the impact to pressure gauge.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The embodiments of the present invention include tubular shell 1, and filter core 2, the pipe of tubular shell 1 are equipped in tubular shell 1
The mounting hole that inner end is communicated with shell inner cavity is offered on wall and pressure tapping 3, pressure gauge are fixedly installed at the mounting hole
Pressure gauge is installed for showing shell inner cavity lubricating oil pressure on connector 3.In order to increase by 3 root sealer performance of pressure tapping,
Plain cushion 4 is fixedly installed between pressure tapping 3 and the mounting hole.
As shown in Figure 1, the filter core 2 includes filter screen joint 22, the outer end of filter screen joint 22 close to tubular shell 1 into
Oily end, the inner end of filter screen joint 22 are welded with tubular filter screen 23, and the outer end of tubular filter screen 23 is welded with strainer end socket
24.The external screw thread opened up on the outer wall of filter screen joint 22 is worked in coordination with 1 internal screw thread of tubular shell and is connect.Filter screen joint 22 is also opened
Equipped with interior six hole 21.When needing to load and unload filter core 2, interior six hole spanner is inserted into rotation process in interior six holes 21.
The mounting hole is located between 1 oil outlet of filter screen joint 22 and tubular shell.Offered in pressure tapping 3 according to
The secondary oil suction chamber 33 communicated, adapter cavity 32 and pressure gauge installation cavity 31.The inner wall of pressure gauge installation cavity 31 offer internal screw thread with
The external screw thread of pressure gauge oil inlet pipe is cooperatively connected.Oil suction chamber 33 is communicated with the shell inner cavity, and adapter cavity 32 is installed by pressure gauge
Chamber 31 is communicated with pressure gauge oil inlet pipe.The diameter of adapter cavity 32 is less than the diameter of oil suction chamber 33, the diameter of adapter cavity 32 again smaller than
The diameter of pressure gauge installation cavity 31, the lubricating oil that high speed enters from shell inner cavity successively pass through relatively thick, relatively thin and then thicker three
Chamber, flow velocity are substantially reduced, to alleviate the impact to pressure gauge.
Its working principle is that: the lubricating oil as liquid medium enters from 1 oil inlet end of tubular shell, filters through filtration core 2
Afterwards, clean liquid medium is flowed out from 1 oil outlet of tubular shell, and the clean liquid medium in part enters through pressure tapping 3 presses
Power table, pressure gauge show loine pressure.
