Method of application:
When a kind of medium and heavy lorry automatic water sprayer of the utility model uses; The open contact of I relay 3 and II relay 4 is closed; Radiator water spray relay indicating light 5 is shinny, and expression radiator cooling system is worked, and the open contact of III relay 6 and IV relay 7 breaks off; Brake wheel water spray relay indicating light 8 extinguishes, and expression brake wheel sprinkler is not worked; When vehicle under steam, by No. 3 lines power supply of heavy wrecker truck wire harness 16, an end of radiator temperature control inductive switch 14 and brake disc temperature control inductive switch 15 all has; But not conducting, two shower heads are not all sprayed water, when the temperature build-up of driving engine causes the temperature of heavy wrecker truck radiator also to increase; When temperature is raised to the higher limit of radiator temperature control inductive switch 14 settings, be installed in the just conductings automatically of temperature control inductive switch 14 on the heavy wrecker truck radiator, to the suction coil power supply of I relay 3; Because the suction coil of I relay 3 obtains pick-up voltage and adhesive, make its open contact closed, radiator water supply electromagnetic valve 19 also obtains voltage and adhesive; Open the water supply line of radiator shower head 17, the suction coil of II relay 4 also obtains pick-up voltage and adhesive at the same time, makes its open contact also closed; Connected the power supply of radiator water spray relay indicating light 5 and D1 diode 9 simultaneously, made radiator water spray relay indicating light 5 shinny, this just representes that the radiator water-injection system works; Since D1 diode 9 obtains be forward voltage with regard to conducting, connect the power supply of water pump 25, water pump 25 just starts running and supplies water to radiator shower head 17; Radiator shower head 17 begins to heavy wrecker truck radiator appearance water spray, and this moment, D2 diode 10 obtained is reverse voltage and ending, and brake wheel water spray relay indicating light 8 does not work; Expression brake wheel cooling system is not worked; So brake wheel water supply electromagnetic valve 21 is closed, 25 on water pump supplies water to radiator shower head 17, makes the temperature of heavy wrecker truck radiator begin to descend; Thereby the temperature of driving engine is also descended thereupon, reach the purpose that reduces engine temperature.When the temperature of heavy wrecker truck radiator drops to the lower limit of radiator temperature control inductive switch 14 design temperatures, with regard to automatic cutout, and the pick-up voltage of cut-out I relay 3 suction coils; The suction coil is discharged; Open contact breaks off, so the suction coil of II relay 4 also loses pick-up voltage and discharges, its open contact is also broken off; Cut off the power supply of D1 diode 9, water pump 25 and radiator water spray relay indicating light 5 simultaneously; Make water pump 25 stalls, radiator water spray relay indicating light 5 extinguishes, and radiator water supply electromagnetic valve 19 also loses pick-up voltage and closes water supply line at this moment; Radiator shower head 17 quits work, and no longer sprays water to heavy wrecker truck radiator appearance.
The normally closed contact of said I relay 3 and II relay 4 breaks off; Radiator water spray relay indicating light 5 extinguishes; The radiator water-injection system is not worked; The normally closed contact of III relay 6 and IV relay 7 is closed, and brake wheel water spray relay indicating light 8 is shinny, just representes that the brake wheel water-injection system works.
When the temperature on the brake disc rises to the higher limit of brake disc temperature control inductive switch 15 design temperatures, be installed in the just conductings automatically of temperature control inductive switch 15 on the heavy wrecker truck brake disc, and connect pick-up voltage and the adhesive of III relay 6 suction coils; Make the open contact of III relay 6 closed, make brake wheel water supply electromagnetic valve 21 get electric adhesive and open water supply line, the suction coil of IV relay 7 also obtains pick-up voltage and adhesive at this moment; Make its open contact also closed, connect the power supply of brake wheel water spray relay indicating light 8 and D2 diode 10 simultaneously, make brake wheel water spray relay indicating light 8 shinny; Because D2 diode 10 obtains forward voltages with regard to conducting,, be reverse voltage and ending but D1 diode 9 obtains to D1 diode 9 and water pump 25 power supplies; Have only water pump 25 electric and turn round, supply water to brake wheel shower head 26, brake wheel shower head 26 begins to spray water to brake wheel; Force the temperature of brake wheel to begin to descend, when the temperature of brake wheel dropped to the smallest limit of brake disc temperature control inductive switch 15 design temperatures that are installed on the heavy wrecker truck brake disc, brake disc temperature control inductive switch 15 was with regard to automatic cutout; And the pick-up voltage that cuts off III relay 6 suction coils also discharges; Its open contact is opened, and makes the suction coil of IV relay 7 also lose pick-up voltage and discharges, and open contact is also opened; Thereby cut off the power supply of brake wheel water spray relay indicating light 8 and D2 diode 10 and water pump 25; Brake wheel water spray relay indicating light 8 is extinguished, and water pump 25 stops, and no longer supplies water to brake wheel shower head 26; Brake wheel water supply electromagnetic valve 21 is also closed at this moment, and brake wheel shower head 26 stops to spray water to brake wheel.
When carrying out water tank 27 maintenances and maintenance, close inlet valve 24, water cock 22 is opened the water of emitting in the water tank, can carry out.
