Abstract
The utility model relates to the field of electric welding machines, and in particular to an electric welding machine draught fan which comprises a temperature relay, a draught fan and a draught fan power supply. Two contacts of the temperature relay are connected with a power supply after a serious circuit is formed by the two contacts and the draught fan. When a temperature sensor of the temperature relay detects that the temperature of electrical components in the welding machine exceeds temperature preset value, the temperature relay is communicated, and the draught fan works. When the temperature sensor of the temperature relay detects that the temperature of the electrical components in the electric welding machine is below the temperature preset value, the draught fan stops working. The electric welding machine draught fan is capable of effectively controlling opening and closing of the draught fan according to the temperature in the electric welding machine in real time, saving energy effectively and prolonging service life of devices.

Background technique
in engineering construction, welding equipment is indispensable construction equipment.Welding equipment has a large amount of standby time in the front and back of welding process, and within these times, the electrical device of the inside of most of welding machine is still in operation, and open circuit voltage is upper and lower in 70V, and also continuous running of blower fan, has caused the waste of the energy.The power consumption that has comprised running wastage and the blower fan of electrical device.The artificer of large-tonnage product thinks, blower fan just exists in order to protect the electric welding machine internal components, ignores the energy waste of this respect and the working life of blower fan.
Only having the small part product to do the electric welding machine fan intelligent controls.Usually adopt software or hardware utilization timing principle to do the control of electric welding machine blower fan, thereby realize energy-conservation.But these ignore the true temperature of ambient temperature and internal components, very imperfect to the protection of its internal components, be the mechanical welding startup of having accomplished, the blower fan running; Welding stops, blower fan time delay stall.Adopt said method to control the electric welding machine blower fan, can realize the electric welding Fan Energy-saving to a certain extent, but insensitive to electric welding machine inside true temperature and ambient temperature reaction, but still exist the unscientific situation of electric welding machine air-blower control, the problem of the same power consumption existed, the situation that simultaneously also may cause the overheated electric welding machine caused of electric welding machine internal circuit to damage.
The model utility content
Goal of the invention of the present utility model is: control inadequate science for present electric welder, a kind of electric welding machine blower fan is provided.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of electric welding machine blower fan, described electric welding machine blower fan comprises temperature relay, blower fan, fan power, two contacts of described temperature relay with power supply, be connected after wind mechanism becomes series circuit.
Above-mentioned blower fan control system is controlled the running of electric welding machine blower fan, is incorporated in a closed loop control based on temperature relay energy-saving and noise-reducing, the working life of energy extension device.
Preferably, described temperature relay and a switch in parallel.
When temperature relay breaks down, the contact of close switch, when equipment is used, the electric welding machine blower fan still can carry out work.Thereby improve the emergent performance of electric welding machine blower fan.
Preferably, described temperature relay is many, described many temperature relay parallel connections.
Temperature relay quantity is arranged according to Temperature Key point in electric welding machine, and when wherein a temperature relay is connected, blower fan is started working.
The preset temperature value of described temperature relay can be identical can be not identical yet.Can be arranged according to the actual conditions of Temperature Key.
Can be monitored a plurality of Temperature Key points in electric welding machine, when wherein certain Temperature Key point temperature raises, blower fan starts working, thereby avoids single temperature relay not comprehensive to the perception of electric welding machine inside temperature, makes the inner local superheating of electric welding machine and damages electric welding machine.
Preferably, the temperature transducer of described temperature relay uses heat-conducting silicone grease to be fixed on electric welder transformer or rectifier equitemperature key point.
Can lower the thermal resistance between temperature relay and internal components, improve the sensitivity of temperature monitoring.
Described fan power derives from the electric welder transformer input power or derives from the electric welder transformer out-put supply.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
Adopt temperature relay to control the work of electric welding machine blower fan, can be effectively energy-conservation, and the working life of energy extension device.The electric welding machine blower fan system has good emergent performance.
