The specific embodiment
The automatic water-cooling apparatus of a kind of goods carrying vehicle drg is made up of lack of water warning, reserve tank (2), temperature sensor (9), injection flow rate control system (6), electromagnetic throttle valve (5), water injecting system (8) and water pipe (4).
According to the constructional feature of goods carrying vehicle drum brake mechanism, be in the vehicle traveling process at the beginning of automobile brake, brake wheel (7) rotates with wheel, because the needs of information transfer, thermocouple temperature sensor (9) can not be directly installed on the brake wheel (7).Therefore for thermocouple temperature sensor (9) is not rotated with brake wheel, and can accurately detect variation of temperature, so thermocouple temperature sensor (9) is installed in the top of the brake wheel cylinder very approaching apart from the brake wheel running surface.
The lack of water warning is crossed low alarm switch (3) and water level by water-level indicator (1), water level and is crossed low alarm lamp etc. and form; It mainly acts on is the water yield in the indication coolant storage tank; Cross when low when the water yield this signal is passed to chaufeur through the alarm lamp that is installed on the gauge panel, remind chaufeur in time to add water.Alarm lamp is installed on the facia board, and when the water yield in the reserve tank reduces to specified value when following, thermally dependent resistor surfaces, and heat radiation is slow; Temperature is higher, and resistance value is less, and electric current is bigger in the circuit; The lack of water alarm lamp is lighted automatically, notes to remind chaufeur, adds cold water in good time; When the water yield more for a long time, thermally dependent resistor is under water, rapid heat dissipation, temperature is low, resistance value is big, current value is very little, alarm lamp does not work.
Injection flow rate control system (6) is made up of temperature sensor (9), AT89C51 micro controller system, amplifying circuit and electromagnetic throttle valve (5); It mainly acts on is through detecting the working of brakes temperature; More accurately control is sprayed onto the cooling water inflow on the drg, and the working of brakes temperature is remained on below 100 ℃ with normal operation.In addition; In order to make water-injection system have enough water spray pressure; Be provided with the dedicated line that is connected with storage tank (Pneumatic braking system) in the upper end of water tank; Behind high pressure air in storage tank process reducing valve, the check valve cooling water expansion tank in the water tank is applied certain pressure like this, can guarantee that cooling water expansion tank sprays with elevated pressures, can prevent that also antipriming pipe stops up.Utilize the Single-chip Controlling electromagnetic throttle valve according to the temperature of drg, thus control water injecting system water spray, the following stable operation of temperature (100 ℃) that drg is being set.Control system is made up of MAX6675 type thermocouple sensor, AT89C51 micro controller system, amplifying circuit and electromagnetic throttle valve.MAX6675 type thermocouple sensor converts the brake wheel temperature signal that records into electric potential signal; Thermocouple amplifier and quanxtizer through thermocouple amplifier, cold junction compensation, A/D converter and SPI serial ports; Input micro controller system and setting value compare; If the signal that collects is greater than setting value, micro controller system sends instruction, opens electromagnetic valve the brake wheel trickle is lowered the temperature; Less than setting value, micro controller system does not send instruction like the brake wheel temperature, and electromagnetic valve is in closed condition.
The reserve tank of cooling system (2) is fixed on the crossbeam of car chassis, is provided with dividing plate in it, and dividing plate is installed in tank top; Lower end and water tank bottom are separated by a distance; Cooling water expansion tank in the water tank plays buffer action, and water gauge (1) is arranged on the side outside of water tank, adopts the lucite pipe with the inner UNICOM of water tank; Water level is crossed low alarm switch (3) and is arranged on the inside near water tank bottom, the 10cm place apart from the bottom.Admission port is located at tank top and communicates with the inside of water tank, and the filler is at the top of water tank, and blow off valve places the bottom correct position of water tank; Admission port communicates with the high pressure air of storage tank through gas source valve, reducing valve, guaranteed the enough pressure of water spray, and admission port is equipped with the air inlet switch, conveniently adds water.
The water outlet of electromagnetic throttle valve links to each other with the water inlet of water injecting system (8) through water pipe (4), is installed between the water outlet and water injecting system (8) of water tank (2), is used for the injection flow rate of control flows to water injecting system.Its principle of work is to control injection flow rate through the current time pulse change electromagnetic valve time of opening of control input, and in the time need not spraying water, spool is SELF CL under the effect of pull back spring.
