Description
Technical field
The utility model relates to the temperature control system that the hydraulic construction machines such as a kind of excavator, loader, dynamic compaction machinery are used.
Background technique
The engineering machinery of excavator, loader, dynamic compaction machinery class is a kind of driven by engine oil hydraulic pump that uses, and does medium transferring energy with hydraulic oil, taking hydraulic jack, oil hydraulic motor etc. as performer, drives equipment to carry out the engineering machinery of related work.Motor is the source of power output, and hydraulic oil is the medium of transmission of power, and the two has a common feature, and its service behaviour temperature influence is very large, directly translates into the impact on power performance of engine temperature and hydraulic fluid temperature; Motor need to remain on competence exertion in certain temperature range and go out higher working efficiency and best fuel economy, the too low consumption that can increase fuel oil of temperature of motor, and can there is overtemperature alarm or cause motor to damage in excess Temperature.Equally, the too high or too low for temperature of hydraulic oil can affect hydraulic pressure oil viscosity, causes the Efficiency Decreasing of hydraulic oil transferring energy, and then affects the working efficiency of complete machine.Therefore, motor and hydraulic oil need special sink, and mainly taking water (cooling liquid) as medium, logical heat transfer dispels the heat motor.
The radiating mode of tradition engineering machinery is stacking before and after engine radiator and hydraulic oil radiator, to installation, drive blade rotary by engine crankshaft with engine blower sharf, make air stream through radiator, take away the temperature of cooling liquid and hydraulic oil, reach the effect of cooling.This radiating mode is simple in structure, with low cost, but radiating effect is subject to the impact of engine speed height, and uncontrolled, need only engine operation, cooling liquid and hydraulic oil just keep lasting radiating state, and engine speed is high, heat dissipating capacity is large, and rotating speed is low, and heat dissipating capacity is little.In the time that ambient temperature is lower, owing to continuing the effect of heat radiation, what engine temperature and hydraulic fluid temperature can not be very fast brings up to optimum working temperature, causes the decline of engine efficiency reduction and power performance, and then reduces the working efficiency of engineering machinery.
Model utility content
The technical problems to be solved in the utility model is to provide the temperature control system that the hydraulic construction machines such as a kind of excavator, loader, dynamic compaction machinery are used.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: hydraulic construction machine temperature control system, comprise radiator, be arranged on multiple electronic fans, controller and temperature transducer on radiator, described temperature transducer is arranged on respectively in motor and hydraulic oil container, described electronic fan is connected transmission of electric signals with temperature transducer with controller, and controller is transferred to communication data the instrument of the hydraulic construction machine being attached thereto.
Further, described radiator inner compartment is divided into the hot radiating part of cooling liquid and hydraulic oil radiating part, and electronic fan is arranged on the position that radiator is corresponding side by side.
Adopt the beneficial effect of the technical solution of the utility model: the temperature of motor and hydraulic oil is controlled separately, ensure that the temperature of motor and hydraulic oil maintains in the reasonable scope, improve the working efficiency of motor and hydraulic equipment, improve the working efficiency of complete machine.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural front view of the present utility model;
Fig. 2 is electric logic block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Fig. 1, the temperature control system of hydraulic construction machine shown in Fig. 2, comprise radiator 1, described radiator 1 inner compartment is divided into the hot radiating part 12 of cooling liquid and hydraulic oil radiating part 11, be arranged on side by side locational multiple electronic fans 2 of radiator 1 correspondence, controller and temperature transducer, described temperature transducer comprises and is arranged on in-engine cooling-water temperature sensor and is arranged on the oil temperature sensor in hydraulic oil container, described electronic fan is connected transmission of electric signals with temperature transducer with controller, controller is transferred to communication data the instrument of the hydraulic construction machine being attached thereto.
At the inner preset corresponding control program of controller, controller is according to preset parameter and the temperature data detecting, by logical operation, control certain electronic fan work or certain several electronic fan is worked simultaneously and the rotating speed of electronic fan, adjust in real time the working state of electronic fan by controller, guarantee that motor and hydraulic oil all remain on suitable temperature range, make motor and hydraulic work system in optimum efficiency interval, real-time detection by controller to temperature, control in real time the working state of electronic fan, ensure that temperature maintains suitable scope, improve working efficiency and the fuel economy of complete machine.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
