Abstract
The invention provides a hydraulic oil tank, and relates to the technical field of engineering machinery. The hydraulic oil tank comprises a tank body and an oil return pipe. An oil return cavity is formed in the upper portion of an inner cavity of the tank body. The oil return pipe is arranged in the inner cavity of the tank body. The bottom end of the oil return pipe is communicated with an oil return opening in the bottom of the tank body. The top end of the oil return pipe is communicated with the oil return cavity which is communicated with the inner cavity of the tank body through a return oil filter element in the tank body. Compared with the prior art, pipelines are simplified, the installation space is reduced, the problem that installation is difficult is solved, cost is reduced, the hydraulic oil enters the oil return cavity firstly to be buffered, the impact of the return hydraulic oil on the return oil filter element is reduced through the return oil filter element, and the normal work of a whole oil return system is ensured.
Description
Technical field
The present invention relates to technical field of engineering machinery, especially a kind of hydraulic oil container.
Background technique
Loader is the one of engineering machinery, and be widely used in the engineering fields such as building, road, mine, harbour, the Main Function of loader carries out shovel to pretend industry.
Comply with the main trend of energy-saving and emission-reduction development, loader hydraulic system is in continuous upgrading, hydraulic system starts to widely apply plunger pump, because plunger pump requires harsher to oil suction, in order to prevent occurring at work inhaling sky, require that oil suction position is higher than pump mounting point, hydraulic oil container adopts backpack to install, the mounting point of this kind of hydraulic oil container is relatively high, arranges return tube as being also retained in hydraulic oil container top, then return line becomes complicated, and it is large to take up space, hydraulic oil container installs difficulty, and complex structure, cost is high.
Summary of the invention
The invention provides a kind of hydraulic oil container, it can solve the problem that existing backpack hydraulic oil tank structure is complicated, install difficulty.
In order to solve technique scheme, the technical solution adopted in the present invention is: it includes casing and return tube, described cabinets cavity top is provided with oil back chamber, described return tube is arranged in described cabinets cavity, this return tube bottom is communicated with the return opening being located at described bottom half, this return tube top is communicated with described oil back chamber, and described oil back chamber is communicated with described cabinets cavity by the oil return filter core be arranged in described casing.
In technique scheme, scheme can also be more specifically: described oil back chamber is welded at described cabinets cavity dividing plate; Described oil return filter core is fixedly connected with described casing by fastening piece.
Further: described return tube is fixedly connected with described casing by fastening piece.
Owing to adopting technique scheme, the present invention with enjoy compared with technology, there is following beneficial effect:
(1), because return opening is located at bottom half, the return tube be connected with return opening is located in cabinets cavity, and hydraulic system, by bottom oil return, simplifies pipeline, reduces installing space, solves installation difficulty, reduces costs.
(2), owing to being provided with oil back chamber on cabinets cavity top, return tube is arranged in cabinets cavity, return tube bottom is communicated with the return opening being located at bottom half, top is communicated with oil back chamber, and oil back chamber is communicated with cabinets cavity by oil return filter core, and hydraulic oil-returning is introduced into oil back chamber, cushioned, again by oil return filter core, reduce hydraulic oil-returning to the impact of oil return filter core, guarantee the normal work of whole oil return system.
(3), effectively can eliminate bubble, improve the reliable life of hydraulic system element;
(4), oil return filter core can extract out from hydraulic oil container top, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Reference character of the present invention is as follows:
1, casing; 2, steel pipe; 3, oil return filter core, 4, oil back chamber, 5, return opening, 6, dividing plate, 7, oil outlet.
Embodiment
Below in conjunction with attached Example, the invention will be further described:
The present embodiment as depicted in figs. 1 and 2, include casing 1 and return tube 2, casing 1 inner chamber top is provided with oil back chamber 4, return tube 2 is arranged in casing 1 inner chamber, this return tube bottom is communicated with the return opening 5 be located at bottom casing 1, this return tube top is communicated with oil back chamber 4, and oil back chamber 2 is by being arranged on oil return filter core in casing 13 and casing 1 inner space; Oil back chamber 4 is welded at casing 1 inner chamber dividing plate 6, and return tube 3 is by screw and be fastened in casing 1; Oil return filter core 3 is fixedly connected with casing 1 by screw.
When being provided with the loader work of this hydraulic oil container, hydraulic oil is at casing 1 internal circulation flow, hollow arrow in Fig. 1 shows the flow direction of hydraulic oil, as indicated with an arrow, hydraulic oil drains into the oil back chamber 4 of casing 1 by return tube 2, is cushioned in oil back chamber 4, the inner chamber of casing 1 is entered again by oil return filter core 3, the oil outlet 7 of oil return filter core 3 is immersed in below hydraulic pressure pasta, and the flow path of hydraulic oil is elongated thus, ensures time enough and eliminates bubble and heat radiation.
Because the oil back chamber 4 of casing 1 and the inner chamber of casing 1 are isolated, be realized by dividing plate 6 Type of Welding, processing is simple, and intensity is large, is easy to realize.
Claims (3)
1. a hydraulic oil container, include casing and return tube, it is characterized in that: described cabinets cavity top is provided with oil back chamber, described return tube is arranged in described cabinets cavity, this return tube bottom is communicated with the return opening being located at described bottom half, this return tube top is communicated with described oil back chamber, and described oil back chamber is communicated with described cabinets cavity by the oil return filter core be arranged in described casing.
2. hydraulic oil container according to claim 1, is characterized in that: described oil back chamber is welded at described cabinets cavity dividing plate.
