| titleOfInvention | A kind of explosion-proof method of electric welding machine |
| abstract | The present invention relates to a kind of explosion-proof method of electric welding machine, the explosion-proof method of this electric welding machine belongs to electrical explosion proof field, he is suitable for the combustible and explosive areas electric weldings such as mine, chemical industry.The present invention is placed on the electric welding machine, contactor and other protections that are easy to produce electric spark inside flameproof enclosure with control circuit and constitutes the flame proof source of welding current; it is cooling that the high pressure nitrogen that electric arc is sprayed by welding gun inner nozzle is generated in welding process near torch head; it is cooling that the high pressure water that the red-hot molten iron near weldment is sprayed by welding gun outer nozzle is sprayed onto welding process; methane gas content near welding gun is detected by firedamp sensor; the flow of high pressure nitrogen and water is detected by flow sensor, controls explosion-proof source of welding current connecting and disconnecting of the circuit by control cable. |
