Abstract
The utility model discloses a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection, it is characterized in that, this system comprises fuel tank (1), return filter (2), cooler (3), accumulator (4) and one-way valve (5), the described cooler being connected with the oil return circuit of main valve (3) is connected with fuel tank (1) by filter (2), external accumulator (4) and one-way valve (5) on oil return circuit; Described one-way valve (5) is connected with fuel tank (1).The technical problem that the utility model solves is to provide a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection, and this device can protect rig radiator by high pressure and hydraulic shock, not damaged effectively.
Description
Technical field
The utility model belongs to rig radiator protection field, particularly a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection.
Background technique
Along with the application of hydraulics, to engineering machinery, brought easily simultaneously, also exist some shortcomings part, such as hydraulic system is to responsive to temperature.In the continuous firing of rig, in order to prevent the rising of oil temperature, hydraulic system all can increase cooling unit, and generally adopts air cooled chiller, in system, in order to filter out the impurity in system, has all increased oil return filter core.Because general rated pressure only has 1.6MPa, if the operating time is very long, and more renew cartridge is not able to do in time, the impurity that system is brought will accumulate, when running up to a certain degree, will cause return filter to stop up, radiator will bear back pressure and causes pressure to raise so, when pressure reaches the rated pressure of radiator, will damage radiator.
In rig work, if while running into harder soil property, during for convenient propelling angle, the general way of oil cylinder is to promote rotatable handle to do clockwise and anticlockwise to-and-fro motion, in so heavy working condition, because the moment opening and closing meeting of rotary manual valve causes larger hydraulic shock, this impact meeting is delivered in radiator along pipeline, although at this moment oil return filter core does not stop up, if bearing this impact, radiator also can cause radiator infringement.
Model utility content
The purpose of this utility model is to provide a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection, and this device can protect rig radiator by high pressure and hydraulic shock, not damaged effectively.
In order to reach above object, the technical solution adopted in the utility model is: a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection, it is characterized in that, this system comprises fuel tank (1), return filter (2), cooler (3), accumulator (4) and one-way valve (5), the described cooler being connected with the oil return circuit of main valve (3) is connected with fuel tank (1) by filter (2), external accumulator (4) and one-way valve (5) on oil return circuit; Described one-way valve (5) is connected with fuel tank (1).
The beneficial effects of the utility model are to provide a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection; this device has been set up thermal accumulator and one-way valve; can effectively divide the hydraulic shock of release system and reduce the high pressure that system produces because of emergency case, thereby extend the working life of radiator.
Accompanying drawing explanation
Fig. 1 is hydraulic scheme of the present utility model.
At the numerical reference described in Figure of description, be expressed as: 1, fuel tank; 2, return filter; 3, cooler; 4, accumulator; 5, one-way valve.
Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Referring to Fig. 1; a kind of hydraulic system for non-excavation level directional drilling machine oil cylinder radiator protection; this system comprises fuel tank 1, return filter 2, cooler 3, accumulator 4 and one-way valve 5; the described cooler being connected with the oil return circuit of main valve 3 is connected with fuel tank 1 by filter 2; external accumulator 4 and one-way valve 5 on oil return circuit, one-way valve 5 is connected with fuel tank 1.
In specific operation, owing to having installed thermal accumulator and one-way valve additional on total oil circuit, while normally working, accumulator and one-way valve are inoperative.Pressure when return filter stops up on total oil circuit can raise, and when pressure reaches 0.5MPa, the one-way valve being contained on total oil circuit is opened.Oil on total oil circuit directly flows back to fuel tank through one-way valve, because total oil circuit is less than the rated pressure of radiator, so can protect radiator.
The accumulator being contained in when rotary manual valve clockwise and anticlockwise to-and-fro motion produces hydraulic shock on total oil circuit can absorb along the next hydraulic shock of pipeline transmission, thereby protection heat radiation wall is undermined.
Applied specific case herein principle of the present utility model and mode of execution are set forth, the explanation of above example is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or without improving, the design of model utility and technological scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
