Abstract
The invention discloses a kind of excavator hydraulic oil case, it is related to engineering machinery field, it includes the oil box of built-in hydraulic oil, a lateral surface for being close to the oil box is provided with hydraulic oil radiator, hydraulic oil radiator is connected by connecting tube with the oil return opening of oil box, and hydraulic oil radiator is connected by system oil return pipe with the oil return opening of hydraulic system.There is oil return and prolong stroke pressure loss in the radiating mode that the present invention can solve existing hydraulic oil container, cause the problem of fuel consumption efficiency reduction, it is also possible to which it is limited to solve whole machine arrangement space, the problem of compact and optimized hydraulic system.
Description
Technical field
The present invention relates to technical field of engineering machinery, especially a kind of hydraulic oil container for being used on excavator.
Background technology
At present, the radiating mode on conventional excavator to hydraulic oil container is：To be connected with pipe more long with hydraulic oil container
Hydraulic oil radiator location arrangements at the radiator fan of engine coordinate front end；And hydraulic oil container is in order to ensure fuel sucking pipe
The convenient main pump side that can be arranged in engine coordinate rear end of layout.This radiating mode is radiated due to hydraulic oil container and hydraulic oil
Device position farther out, is necessarily required to the oil inlet of more long, more complicated pipeline connection oily shed hydraulic fluid port and hydraulic oil container, such as 22
Ton excavator hydraulic oil case enters about 5 meters of flowline overall length with oil cooler.The return line of long and complexity is inevitably resulted in back
Oil prolongs stroke pressure loss, causes the reduction of fuel consumption efficiency.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of excavator hydraulic oil case, and it can solve existing hydraulic pressure
There is oil return and prolong stroke pressure loss in the radiating mode of fuel tank, cause fuel consumption efficiency reduction and whole machine arrangement space limited, compact
The difficult problem of optimization hydraulic system.
In order to solve the above problems, the technical scheme is that：This excavator hydraulic oil case includes built-in hydraulic oil
Oil box, a lateral surface for being close to the oil box is provided with hydraulic oil radiator, the hydraulic oil radiator passes through
Connecting tube is connected with the oil return opening of the oil box, the oil return that the hydraulic oil radiator passes through system oil return pipe and hydraulic system
Mouth connection.
In above-mentioned technical proposal, more specifically scheme can also be：The oil box and the hydraulic oil radiator
It is overall that shell is set to one.
Due to using above-mentioned technical proposal, the present invention to have the advantages that：
1. compact conformation of the present invention, is more beneficial for the optimization of whole machine placement scheme；
2. the present invention shortens or cancels pipeline between radiator outlet and hydraulic oil container, so that reducing oil return prolongs journey loss, is conducive to
Improve fuel consumption efficiency parameter；
3. compact conformation of the present invention, it is possible to decrease the cost of fuel tank and radiating module.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the invention.
Label is expressed as in figure：
1st, oil box, 2, connecting tube, 3, hydraulic oil radiator, 4, system oil return pipe.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
The excavator hydraulic oil case of Fig. 1, including built-in hydraulic oil oil box 1, be close to oil box 1 a lateral surface set
There is hydraulic oil radiator 3, hydraulic oil radiator 3 is connected by connecting tube 2 with the oil return opening of oil box 1, hydraulic oil radiator 3 leads to
System oil return pipe 4 is crossed to be connected with the oil return opening of hydraulic system.Oil box 1 and hydraulic pressure radiator can also be integrally formed formula
Stroke pressure loss is prolonged in structure, the oil return that can so substantially reduce oil pipe line, improves the fuel consumption efficiency of whole machine.
Entirely the hydraulic oil radiating principle of hydraulic oil container is：System high temperature oil enters through oil return pipe 4 into hydraulic oil radiator 3
Row radiating, then from the oil return box of connecting tube 2.Radiator can be by the form cooling down high-temperature hydraulic oil such as air-cooled or water-cooled.
Claims (2)
1. a kind of oil box of excavator hydraulic oil case, including built-in hydraulic oil（1）, it is characterised in that：It is being close to the fuel tank
