Description
Technical field
The invention belongs to engine turbine pressurization system field, be specifically related to a kind of turbo-charger heat protecting equipment.
Background technique
On petrol engine, adopt machine oil of motor own and cooling water to cool off simultaneously at present; to guarantee the turbosupercharger proper functioning; but when engine shutdown; the cooling capacity of machine oil of motor own and cooling water reduces rapidly; this moment, the engine turbine pressurized machine was because action of inertia; its operating temperature is also very high; if its bearing arrangement only lowers the temperature by natural cooling; to cause the bearing wear aggravation; have a strong impact on booster performance and working life; to directly cause the bearing locking when serious, and cause pressurized machine to damage.And for guaranteeing that turbosupercharger is without prejudice, the driver is generally also needing to make motor move a period of time under idling mode after the parking, has both increased the stand-by period, has expended gasoline again.
Summary of the invention
The purpose of this invention is to provide a kind of turbo-charger heat protecting equipment, make turbosupercharger behind engine shutdown, can cool to normal state safely.
For achieving the above object; the present invention has adopted following technological scheme: a kind of turbo-charger heat protecting equipment; comprise water-cooling tube; this device also comprises electronic water pump and control gear; described electronic water pump is in series with engine cooling water pump or is in parallel, and electronic water pump is accepted to be in operation or stop state from the signal of control gear.
As shown from the above technical solution, the present invention is monitored the running state of engine cooling water system by control gear, when the engine cooling water system runs well, electronic water pump is in stop state, and ought be to stall, after the engine cooling water system quits work, control gear is issued drive signal of electronic water pump, electronic water pump brings into operation, thereby cooling water system continues operation, makes turbosupercharger safety lower the temperature.Hence one can see that; the use of this device can make the direct shutting engine down of driver; dally and need not engine idle; improved user's comfort; reduced the cost of driving; can prevent that also motor from causing damage to turbosupercharger because of the direct shutdown of unexpected problem, and this device construction is simple, is convenient to realize.
Description of drawings
Fig. 1 is a system architecture schematic representation of the present invention;
Fig. 2 is the connect structural representation of form of the present invention;
Fig. 3 is the structural representation of parallel form of the present invention.
Embodiment
Shown in Fig. 1～3; a kind of turbo-charger heat protecting equipment; comprise water-cooling tube 10; also comprise electronic water pump 20 and control gear 30; described electronic water pump 20 is in series with engine cooling water pump 40 or is in parallel, and electronic water pump 20 is accepted to be in operation or stop state from the signal of control gear 30.
As shown in Figure 2, electronic water pump 20 is in series with engine cooling water pump 40.This moment, the engine cooling water system need not be done any change, only increases an electronic water pump 20 and get final product in water-cooling tube 10 tunnel.
After to stall, rely on the engine cooling water pump 40 of engine crankshaft belt drive owing to lack power resources stall simultaneously, electronic water pump 20 is accepted to bring into operation from the signal of control gear 30 then, cooling water system continues to finish whole circulation, lowers the temperature safely to realize turbosupercharger.
As preferred version of the present invention, described electronic water pump 20 is in parallel with engine cooling water pump 40, its water inlet is arranged on the outlet port of swelling water tank 50, and water outlet is arranged on engine cooling water pump 40 backs to the water-cooling tube 10 between the water intake of turbosupercharger cooling jacket 60.As shown in Figure 3.
After electronic water pump 20 and engine cooling water pump 40 are in parallel, the cooling water circulation time engine cooling water pump 40 of can not flowing through once more then, thus significantly reduced the resistance of cooling water system operation, shortened working time, reduce operating cost, and improved cooling effect.
As the present invention's preferred version further, the water outlet of described electronic water pump 20 is arranged on the water inlet of turbosupercharger cooling jacket 60.As shown in Figure 3.
In this preferred version, the cooling water circulation time is not only without engine cooling water pump 40, nor through engine cooling water jacket 70, the cooling water recirculation system of this moment has not only significantly reduced the resistance of system's operation, also significantly reduced the temperature of cooling water in the system, further improved the cooling effect of cooling water turbosupercharger.
As shown in Figure 1, described control gear 30 comprises control module 31 and sensor 32.The service data that sensor 32 is collected cooling water system, and this service data passed to control module 31, compare with the design data of internal memory as the foundation of judging that whether cooling water system moves with this service data, judge whether to send drive signal by control module 31 again to electronic water pump 20.
Described sensor 32 comprises throttle valve body position transducer 32A, temperature transducer 32B, speed probe 32C and cooling-water temperature sensor 32D.By above various sensor 32 is set, can comparatively clear and definite understanding be arranged to throttle valve body position, engine temperature, engine speed and cooling water temperature, and then engine system and engine cooling water system there has been understanding clearly, by control module 31 data that collect and the design data of internal memory are compared again, to judge the running state of engine system and engine cooling water system.
Described control module 31 is connected with the switch gear of electronic water pump 20 by a delay circuit, and delay time is 3 minutes.After engine system is out of service, control module 31 is connected the switch gear of electronic water pump 20 by delay circuit, can power to the motor of electronic water pump 20 by the storage battery of automobile, electronic water pump 20 actions, the cooling water system operation, system's operation is after 3 minutes, and the temperature of turbosupercharger can be reduced to safety range, and this device is out of service.
Electronic water pump described in the present invention is common used water pump, and it accepts the drive signal from control gear 30 when starting working, and can be moved by the storage battery power supply of automobile, and hence one can see that, simple structure of the present invention, and be easy to realize.
