Embodiment
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of cooling water automatic thermostatic device, comprise temperature controller 1, A.C. contactor 2, power switch 3, water tank 4, temperature-sensing probe 5, water pump 6, heater 7, described temperature controller 1 is connected with A.C. contactor 2 by circuit, and A.C. contactor 2 is connected with power switch 3 by circuit;
Described temperature controller 1 is connected with water tank 4 by circuit, and the inside of water tank 4 is provided with temperature-sensing probe 5, and temperature-sensing probe 5 is connected with temperature controller 1 by circuit;
Described water tank 4 is connected with cooling device 8 by pipeline, and this pipeline is provided with water pump 6, heater 7, heater 7 is connected with power switch 3 by circuit.
Described temperature controller 1 is connected with temperature-sensing probe 5, the reading can carrying out at any time to the temperature of the cooling water in water tank 4, simultaneously, temperature controller 1 is connected with A.C. contactor 2, can directly control power switch 3, by carrying out the setting of upper and lower end value to the temperature of temperature controller 1, cooling water automatic thermostatic device can be made in the temperature of setting to carry out Automatic-heating to the cooling water in water tank 4, without the need to artificial manipulation, improve production efficiency, save human cost.
Described temperature controller 1 adopts electronic temperature controller.
The exit of described water tank 4 is provided with filter, is filtered by cooling water, prevents from producing device in cooling procedure polluting.
Implementation process:
First temperature controller 1 is carried out to the setting of temperature, upper and lower two end point temperatures are set, when water tank 4 inner cooling water temperature is less than lower limit, temperature controller 1 sends a signal to A.C. contactor 2, and A.C. contactor 2 controls power switch 3, is closed by power switch 3, heater 7 starts, heat the cooling water that water pump 6 is extracted out, when temperature is higher than lower limit, cooling water is allowed for access cooling device; When water tank 4 inner cooling water temperature is greater than higher limit, temperature controller 1 sends a signal to A.C. contactor 2, A.C. contactor 2 controls power switch 3, power switch 3 is disconnected, heater 7 cuts out, water pump 6 stops pumping, until water tank 4 inner cooling water temperature height is when higher limit, cooling water is allowed for access cooling device; When water tank 4 inner cooling water temperature is between endpoints thereof, temperature controller 1 sends a signal to A.C. contactor 2, and A.C. contactor 2 controls power switch 3, is disconnected by power switch 3, and heater 7 cuts out, and water pump 6 draws water, and makes cooling water enter cooling device.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
