Abstract
The utility model relates to a fan controlling device used for an electric welding machine, comprising a fan power supply loop, a solid state relay, a temperature sensor switch, a control power supply circuit and an anti-interference circuit. The control power supply circuit is in connection with an input control signal terminal of the solid state relay; the temperature sensor switch is in connection with the input control signal terminal of the solid state relay through the anti-interference circuit; an output terminal of the solid state relay is in connection with a power supply terminal of the fan power supply loop. The advantages of the utility model are that the fan controlling device controls the starting and stopping of an electric welding machine fan in dependence on temperatures of a temperature sensor; when the temperatures rise, the fan starts to rotate, and when the temperatures fall, the fan stops working, thereby effectively saving electric energy, reducing dust in a machine, prolonging a service life of the fan and achieving great progress.
Description
Technical field:
The utility model relates to a kind of electric welding machine, especially relates to a kind of fan controller that is used for electric welding machine.
Background technique:
In the existing technology, machine intimate can produce great amount of heat during electric welding machine work, and the normal blower fan that adopts carries out wind-cooling heat dissipating to it in order to dispel the heat.Conventional way is electric welding machine one start, and blower fan stops using the shutdown rear fan just to quit work with regard to entry into service until electric welding machine.Because the working state of electric welding machine is a discontinuous, the empty time scale of moving of cutting is bigger, so wasted a large amount of electric power extraly, has also increased machine members simultaneously.On the other hand, when carrying out welding job, can produce amounts of dust, can bring these dust into welding machine inside during blower fan work, cause the inner a large amount of laying dusts of electric welding machine.
The model utility content:
The purpose of the utility model provides a kind of to the existing technology deficiency and saves electric energy, can effectively prolong the fan controller that is used for electric welding machine of fan life.
The purpose of the utility model is to realize through following measure: a kind of fan controller that is used for electric welding machine is characterized in that: it comprises blower fan current supply circuit, solid-state relay, temperature sensor switch, control power circuit, anti-jamming circuit; Said control power circuit connects solid-state relay input control signal end, and temperature sensor switch connects solid-state relay input control signal end through anti-jamming circuit, the solid-state relay Out let machine current supply circuit feeder ear of giving a dinner for a visitor from afar.
Said control power supply is made up of filter capacitor C1, current-limiting resistance R1, DC electrical source.
Said anti-jamming circuit is by anti-interference capacitor C2, C3, C4, and current-limiting resistance R2 forms.
Compared with prior art; The fan controller that is used for electric welding machine that has adopted the utility model to propose has following advantage: this product is controlled the start and stop of electric welding machine blower fan according to the temperature of temperature transducer, and blower fan begins rotation when temperature raises; Blower fan quit work when temperature reduced; Thereby practiced thrift electric energy effectively, reduced the laying dust in the machine, prolonged the working life of blower fan, obtained significant progress.
Description of drawings:
Fig. 1 is the example structure schematic representation that the utility model proposes.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated: an embodiment who provides the utility model at Fig. 1.Among the figure, a kind of fan controller that is used for electric welding machine, it comprises blower fan current supply circuit 1, solid-state relay 2, temperature sensor switch 3, control power circuit 4, anti-jamming circuit 5 compositions.Said control power supply is made up of filter capacitor C1, current-limiting resistance R1, DC electrical source, and DC electrical source is 15V in this instance, supplies power to solid-state relay.Said anti-jamming circuit is by anti-interference capacitor C2, C3, C4, and current-limiting resistance R2 forms, and anti-jamming circuit is for preventing that interference voltage that temperature detect switch (TDS) causes is provided with the influence of solid-state relay input control signal end.Said control power circuit 4 connects solid-state relay 2 input control signal ends, and temperature sensor switch 3 connects solid-state relay 2 input control signal ends through anti-interference circuit 5, solid-state relay 2 Out lets machine current supply circuit 1 feeder ear of giving a dinner for a visitor from afar.
The utility model is like this work: when temperature detect switch (TDS) detects the welding machine inside temperature when low, temperature detect switch (TDS) is closed, and the current potential that will connect solid-state relay input control signal end in fact is pulled down to earth potential; This moment, the solid-state relay control end did not have power supply to supply with, and solid-state relay is not worked, the blower fan non-transformer; Do not turn round, when temperature detect switch (TDS) detects the welding machine inside temperature when too high, temperature detect switch (TDS) breaks off; The current-limiting resistance R1 of control power circuit gives the power supply of solid-state relay control end; Solid-state relay work, blower fan obtains power supply, entry into service.
Combine accompanying drawing to describe the mode of execution of the utility model above; The structure that embodiment provides does not constitute the restriction to the utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in related domain.
