Abstract
The utility model discloses an engineering machinery hydraulic oil tank with a cooling function. The engineering machinery hydraulic oil tank comprises an oil sucking part and an oil returning part, cooling pipes are arranged between the oil sucking part and the oil returning part, the oil sucking part and the oil returning part are provided with an oil sucking filter and an oil returning filter respectively, oil storage cavities are arranged both below the oil sucking filter and the oil returning filter, and the cooling pipes are mutually communicated with the oil storage cavities. Oil draining bolts and fixing frames are arranged below the oil storage cavities, and the lower end of the oil sucking part and the lower end of the soil returning part are provided with an oil sucking opening and an oil returning opening respectively. The engineering machinery hydraulic oil tank has the advantages that the system structure is simplified, the cost is lowered, and the utilization rate of oil liquid is increased. According to the scheme, the oil tank and a cooler are arranged to be of an integral structure, traditional connecting pipelines or other accessories are not arranged between the oil tank and the cooler, the circulating speed of the oil liquid is increased, and the utilization rate of the oil liquid is improved. Thus, the size of the oil tank is made to be smaller, larger space is saved, and mounting and maintaining are convenient.
Description
Technical field
The utility model relates to mechanical equipment technical field, specifically a kind of construction machinery hydraulic oil tank with heat sinking function.
Background technique
Do man-hour in hydraulic system, because the volumetric loss of oil hydraulic pump, oil hydraulic motor, oil hydraulic cylinder and mechanical loss, or the energy of the consumption such as the pressure loss of control unit and pipeline and liquid friction loss, almost all be converted into heat.These heats are dispersed into surrounding space except a part, and major part raises the temperature of fluid and element.If oil liquid temperature is too high, the normal operation of hydraulic system will be had a strong impact on.Generally, for system is remained in a normal working temperature scope, need in system, increase cooling measure.
When the design hydraulic system, reasonably design fuel tank, guarantee that fuel tank has enough volumes and heat diffusion area, can effectively control oil liquid temperature.But, in as engineering machinery, owing to being subject to structural limitations, fuel tank can not be very large; Some adopt the hydraulic system of closed circuit, due to the fluid reciprocation cycle, can not get back to fuel tank cooling; In addition, some hydraulic pressure installation also requirement can be controlled oil liquid temperature automatically, to above occasion, just must take the method for auxiliary heat dissipation, control the temperature of fluid by radiator, make it to be applicable to the requirement of system works.
Traditional hydraulic system adopts the oil tank radiator apart arrangement, can be that car body structure is compacter like this, but has also increased the complexity of system simultaneously.
The model utility content
For above-mentioned technical problem, the utility model provides a kind of construction machinery hydraulic oil tank with heat sinking function.
The technological scheme that the utility model solves its technical problem employing is, a kind of construction machinery hydraulic oil tank with heat sinking function, comprise oil suction part and oil return part, be provided with heat dissipating pipe between described oil suction part and oil return part, described oil suction part and oil return partly are respectively equipped with oil absorption filter and return filter, be equipped with shoe cream room below described oil absorption filter and return filter, described heat dissipating pipe and shoe cream room are interconnected; Described shoe cream room below is provided with oil discharge screw and fixing frame; The lower end of described oil suction part and oil return part is respectively equipped with inlet port and return opening.
The beneficial effect that the utility model produces is,
1, simplied system structure, reduce costs, and increases the fluid utilization ratio.Because this programme adopts fuel tank and the radiator formula structure that becomes one, there is no traditional fuel tank to the connecting pipeline between radiator and some annexes, accelerate speed of circulation and the utilization ratio of fluid, so just can make the volume of fuel tank become less, saved larger space.The convenient installation and maintenance;
2, compact structure, increase radiating efficiency.Because the overall volume of fuel tank diminishes, the circulation fluid in system tails off, large but heat diffusion area becomes relatively, so the radiating efficiency of fluid improves.It is larger that the tradition fuel tank is done, and also can play the effect of part heat radiation, and it is many that the fluid needed becomes, and makes so again the fluid utilization ratio of system reduce.In scheme, accumulator is equivalent to the fuel tank in traditional fuel tank-radiator, and heat dissipating pipe is equivalent to radiator, and the required fluid of volume reduces;
3, reduce traditional fuel tank-radiator ratio and want annex.The tradition fuel tank need to have the cleaning flange, owing to cleaning passable than the great talent that flange must do, has so just increased the volume of traditional fuel tank, at the mounting hole of this programme middle filtrator, can be used as cleanout, has deducted like this design of cleaning flange.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be elaborated:
The structural representation that Fig. 1 is model utility
Fig. 2 is model utility plan structure schematic diagram
In figure, 1, oil absorption filter 2, heat dissipating pipe 3, return filter 4, shoe cream room 5, oil discharge screw 6, fixing frame 7, return opening 8, inlet port
Embodiment
As shown in the figure, a kind of construction machinery hydraulic oil tank with heat sinking function, comprise oil suction part and oil return part, be provided with heat dissipating pipe 2 between described oil suction part and oil return part, described oil suction part and oil return partly are respectively equipped with oil absorption filter 1 and return filter 3, be equipped with shoe cream room 4 below described oil absorption filter 1 and return filter 3, described heat dissipating pipe 2 is interconnected with shoe cream room 4; Described shoe cream room 4 belows are provided with oil discharge screw 5 and fixing frame 6; The lower end of described oil suction part and oil return part is respectively equipped with inlet port 8 and return opening 7;
The utility model is combined as a whole fuel tank and sink, and cardinal principle is as follows: wherein oil return enters fuel tank through return opening 7 and flows according to the direction of arrow, at first passes through return oil filter 3, will enter dirt filtering in fluid; Fluid is entered to oil return part shoe cream room 4 by return filter 3, and then each heat dissipating pipe 2 of flowing through; Now utilize motor or other ancillary methods to drive fan, each heat dissipating pipe 2 blown cooling, accelerate the fluid heat dissipation rate, make through oil liquid temperature can meet job requirement; Enter into oil suction part shoe cream room 4 through overcooled fluid, when needs fluid, fluid can provide oil sources by inlet port 8 through oil absorption filter 1.
The utility model is not limited to above-mentioned mode of execution, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, within all falling into protection domain of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
