Description
Technical field
The invention belongs to engineering machinery thermal cycle management system, be specifically related to a kind of hot blast regeneration management system。
Background technology
The cooling system of Traditional project machinery is to consider heat radiation; the temperature of hydraulic pressure wet goods medium when not paying close attention to low temperature controls; adopt simple being intercepted by hot and cold air; prevent flow of heat source backflow radiator; such management cold district in the winter time usually can occur hydraulic fluid temperature on the low side, causes that hydraulic system transmission efficiency is low, and abrasion is big; exercise not harmony, the phenomenon of thermal source waste。
Summary of the invention
For the drawbacks described above overcoming prior art to exist, it is an object of the invention to, it is provided that a kind of hot blast regeneration management system, at low ambient temperatures, it is achieved the temperature of hydraulic pressure wet goods fluid media (medium) is maintained in rational scope。
Hot blast provided by the invention regeneration management system, it includes temperature sensor, controller and actuator, and described temperature sensor gathers coolant temperature and hydraulic fluid temperature, the temperature information of collection is passed to described controller simultaneously；Described controller sends control instruction to described actuator by calculating, analyze the difference according to real time temperature Yu ideal temperature；Described actuator realizes hot air reflux by the baffle plate opened, close on radiator or blocks hot air reflux, and described actuator controls hot air reflux amount also by the opening degree controlling baffle plate。
Hot blast provided by the invention regeneration management system, it has the beneficial effects that, simple in construction, practical, and reliability is high, and cost is low, and versatility is good；By controlling hot air reflux, control hydraulic pressure wet goods temperature of fluid medium in real time, efficiently solve the problem that under engineering machinery cold snap, hydraulic pressure wet goods temperature of fluid medium is on the low side。In cold weather, greatly improve the complete machine thermal efficiency and working performance, decrease the abrasion of Hydraulic Elements, increase the service life, the effect reducing oil consumption can be obtained simultaneously。

Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, hot blast provided by the invention is regenerated management system and is described in detail。
Embodiment
With reference to Fig. 1-Fig. 2, the hot blast regeneration management system of the present embodiment, it includes temperature sensor 1, controller 2 and actuator 3, and described temperature sensor 1 gathers coolant temperature and hydraulic fluid temperature, and the temperature information of collection passes to described controller 2 simultaneously；Described controller 2 sends control instruction to described actuator 3 by calculating, analyze the difference according to real time temperature Yu ideal temperature；Described actuator 3 realizes hot air reflux by the baffle plate 4 opened, close on radiator or blocks hot air reflux, and described actuator 3 controls hot air reflux amount also by the opening degree controlling baffle plate 4。Described actuator 3 includes servomotor 5, rocking bar 6 and connecting rod 7, and rocking bar 6 connects servomotor 5, connecting rod 7 and rocking bar 6 and is articulated and connected, and described controller 2 sends control instruction to servomotor 5, and servomotor 5 drive rocker 6, connecting rod 7 control baffle plate 4 folding。Rocking bar 6 and connecting rod 7 may be used without mobilizable connected modes such as bolt connection and link together。
Excavator reads real-time coolant temperature and hydraulic fluid temperature situation by temperature sensor 1, calculate through complete machine controller 2, analyze the difference result according to real time temperature Yu ideal temperature and send control instruction to servomotor 5, baffle plate 4 folding is controlled by servomotor 5 drive rocker 6, connecting rod 7, baffle plate 4 aperture is strengthened when real time temperature is lower than ideal temperature, make more hot air reflux to air intake cabin, improve the gas flow temperature flowing through radiator；When real time temperature is higher than ideal temperature, closed baffle plate 4, block hot air reflux, it is ensured that the gas flow temperature flowing through radiator is air themperature。The real-time control of coolant temperature and hydraulic fluid temperature is achieved by above mechanism。
Claims (1)
