Preferably, described paver cooling system also comprises: the display screen that shows the temperature that described controller receives.
From above-mentioned technical scheme as can be seen, the disclosed paver cooling system of the utility model, the temperature of detection of engine cooling fluid in real time, and according to the described speed of cooling fan of the automatic adjusting of the temperature of the engine coolant that detects, make it accurately control in the zone of reasonableness, the cooling fan that has solved existing paver is always with the work of maximal rate pattern, the energy loss problem of higher that the motor that causes can not enter optimum working temperature fast and cause.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the disclosed a kind of structural representation that has the paver of cooling system of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of paver cooling system, works the energy loss problem of higher that the motor that causes can not enter optimum working temperature fast and cause with the maximal rate pattern with the cooling fan that solves paver always.
Moreover, using existing paver to carry out in the construction of the highway process, in case the operating mode of described paver change because cooling fan is worked with the maximal rate pattern always, cooling system can not be adjusted temperature thereupon, can have a strong impact on the work of paver.Adopt the disclosed paver cooling system of present embodiment, when the operating mode of described paver changes, the temperature of the cooling fluid of its motor also can change, described paver cooling system is adjusted the wind speed of cooling fan according to the temperature of engine coolant, and then adjusts the temperature of the cooling fluid of motor.
The disclosed paver cooling system of present embodiment, structure comprises as shown in Figure 1: be arranged on controller 1 and drive unit on the described paver, and be arranged on the temperature pick up 3 on the paver motor 4.
Temperature pick up 3 is gathered the temperature of the cooling fluid of motor 4, and it is transferred in the controller 1.Controller 1 compares temperature signal that receives and the temperature value that presets, and according to the rotating speed of comparative result by accessory drive and then control cooling fan 5, makes the paver engine temperature remain on best temperature range.
Temperature pick up 3 can also be provided with alarm unit, and pre-sets the uniform temperature value thereon, and when the temperature of temperature pick up 3 collections surpassed the temperature value that presets, alarm unit promptly sent warning message, the prompting staff.
Concrete, the drive unit in the foregoing description comprises:
Be connected, drive the hydraulic fan motor 21 of its rotation with cooling fan 5;
Be connected, drive the hydraulic gear pump 22 that hydraulic fan motor 21 turns round with motor 4;
The electro-hydraulic proportional valve 23 of control hydraulic fan motor 21 running powers.
Result after controller 1 compares is: when the temperature of real engine cooling fluid is higher than the temperature that presets, controller 1 outputs signal to electro-hydraulic proportional valve 23, increase the fluid flow that flows through this valve, thereby increase the fluid flow that flows through hydraulic fan CD-ROM drive motor 21, increase hydraulic fan motor 21 running powers.Like this, the rotating speed of cooling fan 5 improves, and has increased intake, causes the temperature of motor to reduce.When the temperature of motor is reduced to preset temperature, controller 1 output signal again reduces and flows through the fluid flow of hydraulic fan CD-ROM drive motor 21, thereby reduced the rotating speed of cooling fan 5 to electro-hydraulic proportional valve 23, reduced intake, made the temperature of motor keep best temperature range.
Otherwise, result after controller 1 compares is: when the temperature of real engine cooling fluid is lower than design temperature, equally, controller 1 outputs signal to electro-hydraulic proportional valve 23, flow through the running power of the fluid flow minimizing hydraulic fan CD-ROM drive motor 21 of electro-hydraulic proportional valve 23 by minimizing, thereby the minimizing speed of cooling fan reduces intake, improves the temperature of motor; When the temperature of motor is reduced to preset temperature, controller 1 output signal again increases the fluid flow that flows through hydraulic fan CD-ROM drive motor 21 to electro-hydraulic proportional valve 23, thereby increases the rotating speed of cooling fan 5, increase intake, make the temperature of motor keep best temperature range.
Through after the above-mentioned operation, the rotating speed of cooling fan 5 will remain within the constant scope, thereby keeps the stable of ECT.
Because described paver hydraulic oil cooling system and motor adopt same cooling fan, if during the variations in temperature of described paver hydraulic oil cooling system, equally also can influence the work of paver, so, in the following embodiments, described paver cooling system, structure equally as shown in Figure 1, also comprise: be arranged on the temperature pick up 7 on the paver hydraulic oil container 6, temperature pick up 7 is used to gather the hydraulic fluid temperature of hydraulic oil container 6, transmits it to controller 1 again.
After controller 1 receives the temperature signal of temperature pick up 7, also itself and the optimum working temperature that presets to be compared, determine the rotating speed of cooling fan 5 according to comparative result, operating process that it is concrete such as the disclosed content of above-mentioned embodiment repeat no more herein.
Equally, alarm unit is set also on temperature pick up 7, also presets certain temperature value thereon, but the temperature that temperature pick up 7 is gathered is when surpassing the temperature value that presets on it, its alarm unit also sends warning message.
In order to make the staff can know clearly the actual temp value that temperature pick up 3 and temperature pick up 7 are gathered, as shown in Figure 1, described paver cooling system also comprises display screen 8, and display screen 8 can be LCDs, the temperature value that display controller 1 receives.Concrete displays temperature sensor 3 and temperature pick up 7 collect and are transferred to the temperature value of controller 1.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
