Description
Technical field
The utility model relates to a kind of road maintenance equipment technical field of hydraulic pressure, and in particular to a kind of supporting equipped with fine filter
Protect equipment circuit apparatus for hydraulic.
Background technique
Existing maintenance class equipment hydraulic circuit filtering carries out oil mostly in the mode of hydraulic pump entrance setting rough filtering device
Filter is passed by, can satisfy general circuit requirements.It is existing but as hydraulic device control precision is continuously improved in maintenance of equipment
Oil circuit cannot meet the requirements well.
Summary of the invention
Utility model aims to solve the problems of existing hydraulic circuit extensive style oil circuit precision controlling deficiency, provide
A kind of maintenance of equipment circuit apparatus for hydraulic equipped with fine filter, enable to oil liquid by after refined filtration more can reliably working liquid
Press loop apparatus.
A kind of maintenance of equipment circuit apparatus for hydraulic equipped with fine filter of the utility model, including hydraulic pump, the hydraulic pump
It exports oil liquid and enters motor 5-linked valve after fine filter, hydraulic pump is connect by valve with fuel tank, hydraulic pump outlet and refined filtration
Device parallel connection is equipped with bypass pipe, and the bypass pipe is equipped with the second control valve, and the first motor of control, the second motor, the are entered after refined filtration
Three motors, the 4th motor, the 5th motor operations 5-linked valve, loop works complete oil liquid back after radiator is cooling, warp
It goes back after crossing oil return filter filtering.
Utility model works principle: opening circuit apparatus for hydraulic, first turns on hydraulic pump, valve, closes the second control
Valve, therefore pipe inner fluid successively passes through valve, hydraulic pump, fine filter, 5-linked valve, heat dissipation under the action of hydraulic pump from fuel tank
Device, oil return filter return to fuel tank, form oil liquid circuit.Oil liquid after unlatching in a period of time flows through fine filter and is filtered, and makes
It is few to obtain oil residue, hydraulic control precision is high.After circuit apparatus for hydraulic the operation is stable, the second control valve, oil liquid part are opened
Enter 5-linked valve from by-pass line, reduce the operating pressure of essential oil device, so that oil liquid flow efficiency is high.
Compared with prior art, the utility model has the following beneficial effects:
Equipment is made to control precision raising, the operation is stable by setting essential oil device and bypass pipe, oil liquid circulation efficiency is high, together
When, considerably increase essential oil device service life.
Detailed description of the invention
Fig. 1 is that this kind of maintenance of equipment hydraulic circuit knot device is intended to.
In attached drawing: 1, oil return filter；2, radiator；3,5-linked valve；4, the first motor；5, the second motor；6, third motor；
7, the 4th motor；8, the 5th motor；9, fine filter；10, hydraulic pump；11, valve；12, bypass pipe；13 second control valves.
Specific embodiment
A kind of maintenance of equipment circuit apparatus for hydraulic equipped with fine filter, including hydraulic pump 10, the hydraulic pump 10 export oil
Liquid enters motor 5-linked valve 3 after fine filter 10, and hydraulic pump 10 is connect by valve 11 with fuel tank, the outlet of hydraulic pump 10 and essence
Filter 9 is in parallel to be equipped with bypass pipe 12, and the bypass pipe 12 is equipped with the second control valve 13, and the first motor 4 of control, the are entered after refined filtration
The 5-linked valve 3 that two motor 5, third motor 6, the 4th motor 7, the 5th motor 8 work, loop works complete oil liquid back through dissipating
After hot device 2 is cooling, go back after the filtering of oil return filter 1.Because this hydraulic circuit working fluid passes through 9 refined filtration of fine filter, therefore it is
The relatively reliable stable realization of this hydraulic circuit work.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
