Abstract

The utility model relates to a hydraulic oil circulation control device for a hydraulic excavator, which is provided with an oil return pipe, a cooling pipe, a heat radiator, a hydraulic fuel tank connecting pipe and a hydraulic fuel tank, wherein the oil return pipe is communicated with the heat radiator through the cooling pipe; the heat radiator is communicated with the hydraulic fuel tank through the hydraulic fuel tank connecting pipe; a three-way solenoid valve is arranged between the oil return pipe and the cooling pipe, one inlet of the three-way solenoid valve is connected with the oil return pipe, one of two outlets of the three-way solenoid valve is connected with the cooling pipe, and the other outlet is connected with the hydraulic fuel tank connecting pipe. The hydraulic oil circulation control device has the benefits that the problems of lower energy efficiency and abrasive hydraulic component caused by too low hydraulic oil temperature are effectively solved, and meanwhile, the shutdown loss of user shutdown and the maintenance and service cost of a host manufacturer caused by the damage of the hydraulic component are effectively reduced.

Description

Hydraulic shovel hydraulic oil cycler
Technical field
The utility model relates to a kind of hydraulic shovel oil path control system, particularly a kind of hydraulic shovel hydraulic oil cycler.
Background technique
Hydraulic shovel is a kind of earth moving machinery that is widely used in engineering construction.Hydraulic transmission is the main rotating manner of hydraulic shovel.The normal working temperature that it has been generally acknowledged that hydraulic oil is 30~65 ℃, and too high oil temperature has harm to system, and low excessively oily temperature also can cause influences such as resistance becomes greatly, transmission efficiency reduction, component abrasion increase.
Present most of excavator cooling system all can only cool off hydraulic oil incessantly, ignored hydraulic oil temperature cross low to hydraulic system influence, therefore exist not enough.
The model utility content
The purpose of the utility model provides a kind of above-mentioned shortcoming that overcomes, and can effectively control the hydraulic shovel hydraulic oil cycler of hydraulic fluid temperature according to temperature variation.
The technological scheme that realizes the utility model purpose is: a kind of hydraulic shovel hydraulic oil cycler; Have return tube, cooling tube, radiator, hydraulic oil container connecting tube and hydraulic oil container; Return tube is through cooling tube and radiator UNICOM, and radiator is through hydraulic oil container connecting tube and hydraulic oil container UNICOM; Be provided with three-way magnetic valve between said return tube and the cooling tube, an import of three-way magnetic valve is connected with return tube, and one of them outlet of two outlets is connected with cooling tube, and another outlet is connected with the hydraulic oil container connecting tube.
The hydraulic oil container connecting tube or the hydraulic oil container of above-mentioned hydraulic shovel hydraulic oil cycler are provided with temperature transducer.
The utlity model has positive effect: the utility model effectively solves because hydraulic oil temperature hangs down low, the hydraulic element wear problem of Energy Efficiency Ratio that causes excessively, and the while effectively reduces owing to hydraulic element damage shutdown loss and the reduction main frame manufacturer maintenance service cost that causes the user to shut down.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the utility model principle schematic.
Embodiment
See Fig. 1, the utlity model has return tube 1, cooling tube 2, radiator 3, hydraulic oil container connecting tube 4 and hydraulic oil container 5, return tube 1 is through cooling tube 2 and radiator 3 UNICOMs, and radiator 3 is through hydraulic oil container connecting tube 4 and hydraulic oil container 5 UNICOMs; It is characterized in that: be provided with three-way magnetic valve 6 between said return tube 1 and the cooling tube 2; An import of three-way magnetic valve 6 is connected with return tube 1; One of them outlet of two outlets is connected with cooling tube 2; Another outlet is connected with hydraulic oil container connecting tube 4, and hydraulic oil container connecting tube 4 is provided with temperature transducer 7.
Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
