Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
As shown in Figure 1, the utility model provides a kind of hydraulic system, and this hydraulic system comprises a plurality of hydraulic works unit 6, and wherein, each hydraulic work unit has an independent cooling fan 1.
In technique scheme; Owing to all be equipped with independent cooling fan 1 for each hydraulic work unit; The operation of these cooling fans of control such as runnability that can each hydraulic work unit of basis and its, hydraulic oil oil tender feeling condition; Thereby reach energy-conserving action, make the good energy-conserving effect of this hydraulic system hydraulic system.Those skilled in the art can be understood that in addition, and in the present technique scheme, cooling fan 1 is through the heat transmission of hydraulic system sheet being carried cooling air, realizing the cooling to hydraulic system.
Below will the utility model be described, but this preferred implementation is not used in restriction the utility model with the preferred implementation of the utility model.In a preferred embodiment, consider that cooling fan can close down or start according to the operation conditions of this hydraulic work unit, control for ease, preferably, each cooling fan 1 is by independent motor driving.Motor is compared the for example more convenient control such as oil hydraulic motor of other driving mode.
In the utility model; In order more directly and accurately to control the operation of cooling fan; The control of preferably cooling fan being carried out according to the oil return oil temperature of this hydraulic work unit, therefore as shown in Figure 1, preferably; The hydraulic system that the utility model provides comprises controller 3; The return line of each hydraulic work unit is provided with temperature transducer 4, and this temperature transducer 4 sends to controller 3 with the value of the temperature that detects, and this controller is controlled said cooling fan 1 according to the value of the temperature that detects and started or stop.Particularly, be provided with threshold value in this controller 3, when the temperature value of temperature transducer 4 detections was lower than this threshold value, controller 3 control cooling fans quit work.And when the temperature value of said temperature transducer 4 detections was equal to or greater than said threshold value, the said cooling fan 1 of said controller 3 controls started.Need to prove; For succinctly; As only partly showing the hydraulic system that the utility model provides among Fig. 1; And only schematically the temperature transducer 4 of a hydraulic work unit, cooling fan 1 are coupled together with controller 3, it should be understood that the temperature transducer of other hydraulic work unit, cooling fan 1 also are connected with controller 3.
In said process, temperature transducer that relates to and controller are parts common in related domain, and for example controller 3 is the PLC controller.In addition; Those skilled in the art can be understood that temperature transducer 4 is arranged on the return line; Be because oil return oil temperature is the oil temperature after the work; Its temperature value can be represented the runnability of this hydraulic work unit, and for example warm when too high when oil return oil, then ordinary representation should be because load of hydraulic work unit be bigger.Therefore, as shown in Figure 1, equally radiating fin also is placed on this oil return circuit, cool off with hydraulic oil, and temperature transducer 4 should be positioned at before the radiating fin, correctly to keep watch on the oil temperature of this hydraulic work unit this hydraulic work unit.
Show that through a large amount of experience and experiments the related threshold value of the utility model is preferably 55 ℃-65 ℃.In actual use; Threshold value should be a particular value in this scope; Certainly in particular cases at some; Those skilled in the art can be arranged on the value outside the threshold value preferable range that the utility model provides with this threshold value, as long as satisfy the purpose of the utility model, it should drop in the protection domain of the utility model equally.
In addition, according to the mode of oil return oil temperature control cooling fan, can also further control the rotating speed of fan, promptly preferably, when the temperature value of temperature transducer 4 detections changed, controller 3 was according to the rotating speed of the variation control cooling fan 1 of this temperature value.Wherein, Can be through a plurality of threshold values be set in controller 3; The corresponding rotation speed of the fan of each threshold value, thereby through temperature value that temperature transducer 4 is detected and a plurality of threshold ratio, when this temperature value meets certain threshold value; By the different rotating speeds of controller 3 control motors realization cooling fans 1, with the hydraulic system good energy saving performance that the utility model is provided.
In addition; The utility model is except using the mode of above-mentioned detection oil return oil temperature; Can also use to detect to be used for because the runnability of working cell is controlled the running of fan, particularly, each hydraulic work unit of the hydraulic system that the utility model provides has a work oil pump 5; Controller 3 is correspondingly controlled cooling fan 1 and is started or stoped according to the state that starts or stops of this work oil pump 5.Particularly, can the various sensors of can the testing pump start or cutting out be set on the oil pump 5, send signal to controller 3 by sensor, thereby realize control, to realize the purpose of the utility model to cooling fan in work.
According to the utility model on the other hand, a kind of vibratory roller is provided, this vibratory roller comprises the hydraulic system that the utility model provides.Except the vibratory roller that the utility model provides, for various places with hydraulic system, the hydraulic system that the utility model provides is suitable equally.
Therefore, hydraulic system that the utility model provides and vibratory roller, the energy saving height has stronger practicability and promotional value.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned mode of execution; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technological scheme of the utility model, these simple variant all belong to the protection domain of the utility model.For example,
Need to prove in addition; Each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
