Description
Technical field
The present invention relates to a kind of fuel tank, more specifically to a kind of hydraulic oil container.
Background technology
Hydraulic oil container is the Fuel Tanking Unit of hydraulic test, and air can be operationally mixed into hydraulic oil by hydraulic test,
Air exists in the form of minute bubbles, while hydraulic test is operationally because the reasons such as abrasion produce chip and are mixed into hydraulic pressure
In oil, therefore existing hydraulic oil container to oily from hydraulic test all containing being filtered and defoaming treatment, is this existing hydraulic pressure
Oil return chamber and oil return filter core are designed with fuel tank, oil return chamber draws oily steel pipe by oil return and communicated with fuel tank internal space, liquid
The oil return of pressure equipment first passes through oil return filter core and enters oil return chamber, then draws the oil that oily steel pipe flow to oil return exterior thereto through oil return
In case space.The hydraulic system of engineering machinery is constantly upgraded, and widely applies plunger pump, because plunger pump compares hydraulic oil requirement
Harshness, the accuracy guarantee and oil return filter core reliability of hydraulic oil is particularly important, and therefore, the control of greasy dirt particle is most important, if
Should try one's best the generation of reduction " cavitation erosion " phenomenon during meter hydraulic system, it is considered to control the bubble accounting in fluid, and in oil return and
Shi Youxiao excludes bubble.Above-mentioned circuit, the bubble in oil return can not be excluded effectively, it usually needs configure plate of cooling down.
The content of the invention
The technical problem to be solved in the present invention is that oily passage froth breaking is drawn in the oil return for being directed to existing oil return chamber to oil storage chamber
The low shortcoming of efficiency, and provide a kind of defoaming effectiveness high hydraulic oil container.
The present invention is such for the technical scheme for realizing its purpose：A kind of hydraulic oil container, including casing are constructed, in casing
Internal oil storage chamber top is provided with oil return chamber, and flat oil return is provided between the oil return chamber and oil storage chamber and is led to
Road.In the present invention, drainback passage is flat, the contact area of increase fluid and wall, improves degassing effect.
Further, in above-mentioned hydraulic oil container, above-mentioned drainback passage be located at the oil return chamber two ends and with the case
The side wall laminating of body.Hydraulic oil is after filter element filtering, and oil is drawn at two ends, and oil return resistance is small, and oil return is more smooth.
Further, in above-mentioned hydraulic oil container, the drainback passage is made up of groove profile steel plate and wallboards of box body, the groove profile
The upper end of steel plate and the side wall of the oil return chamber are mutually welded, and the groove profile steel plate is in its notch position and the wallboards of box body phase
Welding.Drainback passage is constituted by the engagement of groove profile steel plate and wallboards of box body, the material for constituting passage can be saved.
Further, in above-mentioned hydraulic oil container, the bottom plate of the groove profile steel plate is bending plate, its hypomere and the box body wall
Plate is parallel, and epimere is obtuse angle with hypomere angle.
Further, in above-mentioned hydraulic oil container, the ratio of the width of the drainback passage and the width of casing 0.6 to
Between 0.9.The excessively stream flow of drainback passage depends primarily on the cross-sectional area of drainback passage, is ensureing the premise of excessively stream flow
Under, contact area of the hydraulic oil with wallboard in drainback passage is improved, then the width of drainback passage should be wide as much as possible, namely
The width of drainback passage is as far as possible with tank body of oil tank with wide.
The present invention compared with prior art, has the advantages that：
1）Hydraulic oil is after filter element filtering, and oil is drawn at two ends, and oil return resistance is small, and oil return is more smooth.
2）The section girth that oily structure is drawn in oil return is big, and the contact surface of fluid and wallboard is big, and degasification is more preferable.
3）Fluid is along oil tank wall oil return, it is not necessary to be reconfigured at plate of cooling down.

Embodiment
Illustrate specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the hydraulic oil container in the present embodiment includes casing 1, casing 1 constitutes a chamber by wallboard,
Chamber top wallboard formation oil return chamber 3, the bottom of oil return chamber 3 is oil storage chamber 2.It is respectively provided with the two ends of oil return chamber 1
Groove profile steel plate 5, the upper end of groove profile steel plate 5 is mutually welded with constituting the wallboard of oil return chamber 3, positioned at the side plate of the groove profile steel plate on right side
Mutually welded with casing right plate 12, the side plate positioned at the groove profile steel plate in left side is mutually welded with casing left plate 11, groove profile steel plate 5 with
The side plate of casing 1 constitutes drainback passage 4, connection oil return chamber 3 and oil storage chamber 2 at the two ends of oil return chamber.
As shown in Fig. 2 Fig. 3, groove profile steel plate 5 is made up of bottom plate 51 and side plate 52, and biside plate 52 is parallel to each other and vertical base plate
51, bottom plate 51 is bending plate, and its hypomere is parallel with box side, and epimere is obtuse angle with hypomere angle.
In the present embodiment, two groove profile steel plates 5 form drainback passage 4 at the two ends of oil return chamber, and oil return resistance is small, oil return
It is more smooth；The formation of drainback passage simultaneously also uses the wallboard of casing, rational in infrastructure.
In the present embodiment, the width L of drainback passage is greater than the depth D of drainback passage, and flat oil return is constituted with this
Passage.The cross-sectional area that hydraulic oil container is equal to drainback passage by the oil return oil mass of drainback passage is multiplied by the flow velocity of hydraulic oil, right
The hydraulic oil container of a certain equipment is answered, return flow is to determine, therefore the cross-sectional area of drainback passage is also substantially what is determined, is
The contact area of increase hydraulic oil and wallboard, has the width L of increase drainback passage only (while reducing the depth of drainback passage
D), the width between the width namely groove profile steel plate biside plate of the drainback passage therefore in the present embodiment is wide as much as possible, but
It is limited to the width of casing, the ratio between the width of drainback passage and the width of casing are between 0.6 to 0.9.Hydraulic oil is by flat
The contact area of drainback passage, fluid and wallboard is big, and degassing effect is good, fluid along groove profile steel plate and wallboards of box body oil return, without
Configure plate of cooling down.
