Abstract
The invention relates to a hydraulic pressurizing oil tank. The hydraulic pressurizing oil tank comprises a tank body and a piston in the tank body and is characterized in that the tank body is provided with a first cavity and a second cavity, the piston is positioned in the second cavity and fixedly connected with a piston rod, the piston rod is positioned in the first cavity and provided with an inner cavity, and a spring is connected in the inner cavity and fixedly connected with the inner wall of the tank body. The hydraulic pressurizing oil tank is simple in structure and has the advantages of effectiveness in pressurizing, high operational reliability and long service life due to adoption of self-supply type pressurizing as compared with a traditional pressurizing oil tank.
Description
Technical field:
The present invention relates to hydraulic equipment field, particularly the fuel tank of hydraulic system.
Background technique:
In hydraulic system, fuel tank is mainly used to air, the impurity etc. in oil storage, heat radiation and parting liquid force feed.The quality of tank design directly has influence on the functional reliability of hydraulic element and system, especially has conclusive impact for the life-span of oil hydraulic pump.For height above sea level, higher or air pressure is compared with under circlet border, if adopt general open type oil tank, often cause the reduction of oil hydraulic pump inlet pressure and cause the cavitation erosion of oil hydraulic pump, have a strong impact on the normal work of hydraulic system, therefore need to adopt pressurized fuel tank, pressurized fuel tank can increase the pressure on fuel tank pasta, prevents that oil hydraulic pump from producing cavitation erosion, thereby effectively improves the high-level performance of hydraulic system.The shortcoming of traditional pressurized fuel tank is that pressurized effect is not good, is prone to the cavitation phenomenon of fuel tank, and its structure is comparatively complicated.
Summary of the invention:
The applicant, for the above-mentioned shortcoming of traditional pressurized fuel tank, studies and improves, and a kind of hydraulic booster fuel tank is provided, and it has feature simple in structure, that pressurized effect is good.
In order to address the above problem, the present invention adopts following scheme:
A kind of hydraulic booster fuel tank, comprise casing, piston in casing, it is characterized in that: described casing has the first cavity and the second cavity, described piston is arranged in described the second cavity, and described piston is fixedly connected with piston rod, described piston rod is arranged in described the first cavity, described piston rod has inner chamber, linking springs in described inner chamber, and described spring is fixedly connected with cabinet wall.
Further technological scheme is:
Described casing lower end is connected with oil hydraulic pump by pipeline, and described oil hydraulic pump is by the inner chamber of piston rod described in pipeline communication.
Technique effect of the present invention is:
The present invention is simple in structure, more traditional pressurized fuel tank, and owing to adopting the supercharging of confession form, it has advantages of, and pressurized effect is good, functional reliability is high and long service life.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes casing 5, piston 4 in casing 5: casing 5 has the first cavity 1 and the second cavity 8, piston 4 is arranged in the second cavity 8, piston 4 is fixedly connected with piston rod 2, and piston rod 2 is arranged in the first cavity 1, and piston rod 2 has inner chamber 3, the interior linking springs 7 of inner chamber 3, spring 7 is fixedly connected with casing 5 inwalls.Casing 5 lower ends are connected with oil hydraulic pump 10 by pipeline 9, and oil hydraulic pump 10 is communicated with the inner chamber 3 of piston rod 2 by pipeline 6, and the below of casing 5 connects return tube 11.
When working, the present invention utilize spring 7 and piston 4 to the fluid supercharging in fuel tank, along with the increase of oil hydraulic pump 10 outlet pressures, the pressure of the inner chamber 3 of hydraulic oil to piston rod 2 increases, therefore piston 4 moves down, fuel-tank pressurization value is also increased, and the effect of spring 7 is necessary inlet pressures when ensureing to start.
