Background technique
The radiation system of Traditional project machinery is to consider heat radiation; the temperature of the hydraulic pressure wet goods medium during concern low temperature controls; adopt simple being intercepted by hot and cold air; prevent thermal source airflow reflux radiator; usually hydraulic fluid temperature to occur on the low side in cold area in the winter time in such management, and cause hydraulic system transmission efficiency low, wearing and tearing are large; exercise not harmony, the phenomenon of thermal source waste.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, provide a kind of hot blast to regenerate management system, at low ambient temperatures, the temperature realizing hydraulic pressure wet goods flowing medium remains in rational scope.
Hot blast regeneration management system provided by the invention, it comprises temperature transducer, controller and actuator, and described temperature transducer gathers coolant temperature and hydraulic fluid temperature, the temperature information of collection is passed to described controller simultaneously; Described controller sends control command to described actuator by calculating, analyzing according to the difference of real time temperature and ideal temperature; The baffle plate of described actuator by opening, on closed radiator realizes hot air reflux or blocks hot air reflux, and the opening degree of described actuator also by controlling baffle plate controls hot air reflux amount.
Hot blast regeneration management system provided by the invention, its beneficial effect is, structure is simple, and practical, reliability is high, and cost is low, and versatility is good; By controlling hot air reflux, real-time hydraulic control wet goods temperature of fluid medium, efficiently solve the problem that hydraulic pressure wet goods temperature of fluid medium under engineering machinery cold snap is on the low side.In cold weather, greatly improve the complete machine thermal efficiency and operating efficiency, decrease the wearing and tearing of hydraulic element, increase the service life, the effect reducing oil consumption can be obtained simultaneously.
