Abstract
The utility model relates to a centralized oil returning device of a paver. The utility model is characterized in that a hydraulic oil entering and dispersing joint is provided with a hollow tube, and a plurality of oil returning joints which are communicated with the hollow tube in the hydraulic oil entering and dispersing joint are arranged on a wall. One end of an oil returning and centralizing seat is communicated with a hydraulic pressure entering joint, the other end extends in an oil box body, and an oil outlet of the oil returning and centralizing seat is provided with a one-way valve. The utility model has the advantages that appearance is compact, the trouble of arranging and connecting a pipeline is avoided, and the utility model can be used for the design with very little oil returning backpressure and can realize the function with a very strict requirement for oil returning backpressure. The utility model is directly communicated with an oil box through an oil returning and centralizing seat and the one-way valve, can reduce the influence of the pressure drop, etc., of the unstable flow quantity of the pipeline on the oil returning backpressure of a hydraulic element and has the advantages of simple structure, practicality and easy realization.
Description
Technical field
The utility model relates to a kind of paver and concentrates oil return apparatus.
Background technology
At present; the oil return that is used on the paver need be through the oil return of radiator; it mainly acts on this form and can only protect radiator; oil return interflow meeting supercharging through oil return behind the one way valve and radiator; just very difficult for limiting the highest oil return or leaking the protection of pump, motor, valve etc. of oil pressure, and the layout of its pipeline be connected trouble.
Goal of the invention
It is succinct that the purpose of this utility model just provides a kind of outward appearance, saved the trouble of layout and connecting line, can be used in the very little design of return oil pressure, can require very strict function by very good realization return oil pressure, and the pressure drop etc. that can reduce the unstable flow of pipeline is to the influence of Hydraulic Elements return oil pressure, and the paver of simple and practical easy realization is concentrated oil return apparatus.
Solution of the present utility model is such: advancing the hydraulic oil joint that looses is hollow tube, have on the wall a plurality of with advance the hydraulic oil back leakage connection that the interior hollow tube of joint is communicated with that looses; One end of return oil concentrator seat is communicated with the feed liquor crimp head, and the other end stretches in the oil box; Oil-out at return oil concentrator seat is equipped with one way valve.
Advantage of the present utility model: outward appearance is succinct, has saved the trouble of layout and connecting line, can be used in the very little design of return oil pressure, can require very strict function by very good realization return oil pressure; Directly communicate with the fuel tank pressure drop that can reduce the unstable flow of pipeline etc. influences simple and practical easy realization to the Hydraulic Elements return oil pressure through one way valve by return oil concentrator seat.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
The utility model includes oil box 1, return oil concentrator seat 2, tubular type one way valve 3, advances the diffusing joint 4 of hydraulic oil, oil return seat 5.
Of the present utility modelly advance the hydraulic oil joint 4 that looses and be hollow tube, have on the wall a plurality of with advance the hydraulic oil back leakage connection that joint 4 interior hollow tubes are communicated with that looses; One end of return oil concentrator seat 2 is communicated with feed liquor crimp head 4, and the other end stretches in the oil box 1; Oil-out at return oil concentrator seat 2 is equipped with one way valve 3.
In embodiment of the present utility model, described return oil concentrator seat 2 is that T-shaped is connected with advancing the diffusing joint 4 of hydraulic oil, and flange is arranged on return oil concentrator seat 2, and flange is to be fixed on the oil box 1, and described feed liquor crimp head 4 is mounted in the top of oil box 1.As shown in Figure 1.Hydraulic Elements as to limit the highest oil return or leak oil pressure pump, motor, valve etc. oil return or leak oil and under the design back pressure of tubular type one way valve 3, can fully carry out the hydraulic oil heat radiation of loosing through return oil concentrator seat seat 2 backs; Excessive and surpass after the opening pressure of one way valve can unobstructed ground oil sump tank when return pressure, well protected the diffusing and Hydraulic Elements of hydraulic oil.
Oil return after concentrating through the oil return behind the radiator and Hydraulic Elements is two relatively independent oil circuits, has avoided through the oil return interflow of oil return behind the one way valve and radiator and supercharging.
Return oil concentrator seat 2 with advance hydraulic oil and loose and not to be only limited to T-shaped being connected of joint 4 and to connect, also can be offset an end or be the in-line connection.
